The photo on p. 38, the title page of the Ecological Risk Analysis, is of
Bombus (Separatobombus) griseocollis, not the intended Bombus (Pyrobombus)
impatiens. Liz Day brought this obvious misidentification to my attention.
Note the low position of the ocelli, uniformly and deeply infuscated
wings, brownish subappressed hairs on the basal terga, uniformly short and
dense yellowish hairs on the unworn portion of the anterior scutum, etc.
In Bombus impatiens, the lateral ocelli are distinctly below the
supraorbital line; the wings are not uniformly or deeply infuscated; pale
hairs on the basal terga are present only on T1 and these are elongate,
erect, and never brownish; and the hairs of the anterior scutum are more
elongate, not as dense, and a different shade of grayish-yellow.
Numerous correctly identified photos of both species are available online
at www.discoverlife.org, www.bugguide.net, and elsewhere. At
discoverlife.org keys and full descriptions are also available.
The exotic endoparasites of Bombus are somewhat more difficult to identify.

Subject: [Pollinator] Flowers and pollinators
Message-ID:
Flowers shape themselves to guide their pollinators to the pollen
Why do flowers specialize on different pollinators? For example, both bats
and hummingbirds pollinate plants in tropical forests; why adapt to just one
instead of using both? Biologists often assume that tradeoffs contribute to such
specialization (the jack of all pollinators is master of none), yet
surprisingly little evidence exists in support of this idea.
Nathan Muchhala from the University of Miami explored pollinator
specialization through experiments with bats, hummingbirds, and artificial flowers in
cloudforests of Ecuador.
In a study published in the April issue of the American Naturalist, he
reports that the fit between flower and pollinator is key: bats pollinate wide
flowers better, while hummingbirds transfer more pollen between narrow flowers.
Videotaping demonstrated that a poor fit fails to correctly guide the pollinator
while feeding. This tradeoff in adapting to bats vs. hummingbirds is strong
enough to favor specialization on one or the other.
Nathan says, "While all leaves tend to look similar, flowers come in a
spectacular variety of shapes and colors. This study suggests tradeoffs in adapting
to different pollinators may have played an important role in the evolution of
such diversity."

The Honorable XXXXXXX
Office of the Governor
Address
City, State, Zip
Dear Governor XXX:
As a citizen of this state, I would like to take this opportunity to request a proclamation for 'Pollinator Week' the week of June 24 through 30, 2007. The Coevolution Institute has already sent in a request with a variety of information that explains the plight of the declining number of pollinating animals, which are vital to our food supply and a key to sustainability in our world.
With growing concern for pollinators, the United States Senate unanimously approved Resolution 580, which designates June 24 through June 30, 2007, as 'National Pollinator Week.' This was preceded by a proclamation by US Secretary of Agriculture, Mike Johanns also declaring June 24-30 to be National Pollinator Week.
I am writing to ask for your support in helping protect pollinating animals by declaring 'Pollinator Week' June 24 to June 30, 2007 to coincide with what has grown to be an international celebration of pollinating animals including bees, birds, butterflies, bats, beetles and others.
Pollinators are vital to our ecosystems and to supporting terrestrial wildlife, providing healthy watershed, and providing significant benefits to the agriculture.
Please consider joining Indiana, Iowa, Louisiana, Maine, and Michigan, which have already declared Pollinator Week a statewide event, in this movement to support pollinators.
Your consideration and your help are greatly appreciated. Thank you.
Sincerely,
Your Name

I think it is worth pointing out that the paper on Bombus impatiens that David highlighted was one part of a proposal by Koppert Biological Systems, Inc. to allow release of B. impatiens into California for open field pollination. The California Department of Food and Agriculture (CDFA) published a Notice of Intent to adopt a Negative Declaration -- i.e., that the release of the non-native bumble bee will have no impact on the environment -- and the associated initial study under the California Environmental Quality Act (CEQA). The initial study included Joseph Sullivan's paper as an appendix. This proposal was released for public comment in December of last year, and many organizations and individuals from across North America submitted comments by the late-January deadline. The comments from CoEvolution Institute were especially strong and a good model for others.
In brief, the Xerces Society opposed importation of Bombus impatiens, due to the many ecological risks and unknown outcomes of importing this bee. We strongly disagreed with the finding that the prescribed risk mitigation measures adequately addressed the significant ecological risks associated with importation, and believe that the proposed mitigation measures were fraught with vulnerabilities and should not be relied upon as a basis for allowing the importation of B. impatiens. The Society urged the CDFA Division of Plant Health and Pest Prevention Services not to approve the requested permit for importing Bombus impatiens. We believe that there should instead be a focus on the ongoing effort to identify and commercialize bee species that are native to California.
Robbin Thorp contributed greatly to our comments and we received good information from several other researchers, including Sarah Greenleaf and Cory Sheffield. We thank them and everyone else who assisted.

As a foot note, thanks to the efforts of everyone who submitted comments, it looks like the release of impatiens will not be allowed at this stage. CDFA has yet to officially respond to the submitted comments but the feeling is that the Negative Declaration will not be issued. The large number of submissions against the release and the significance of the issues raised in these submissions will likely mean a more detailed and extensive Environmental Impact Report will be required under CEQA.

Subject: [Pollinator] Christian Science Monitor -- What's happening to the
bees?
Message-ID: <200704041111220921.00A06874@smtp.integra.net>
from the April 04, 2007 edition - http://www.csmonitor.com/2007/0404/p13s01-sten.html
What's happening to the bees?
Suddenly, the bees farmers and growers rely on are vanishing. Researchers are scrambling to find out why.
By Moises Velasquez-Manoff | Correspondent of The Christian Science Monitor
Beekeeper James Doan first began finding empty hives last fall. Entire bee colonies seemed to have up and vanished, leaving their honey behind. Noting the unusually wet fall in Hamlin, N.Y., he blamed the weather. Unable to forage in the rain, the bees probably starved, he reasoned.
But when deserted hives began appearing daily, "we knew it was something different," he says. Now, at the beginning of the 2007 pollination season, more than half of his 4,300 hives are gone. "I'm just about ready to give up," says Mr. Doan from his honeybee wintering site in Ft. Meade, Fla. "I'm not sure I can survive."
The cause of the die-offs has yet to be determined. Its effect on the food supply may be significant. Longer-term, it may also force a rethinking of some agricultural practices including our heavy reliance on human-managed bees for pollination.
Scientists call it "colony collapse disorder" (CCD). First reported in Florida last fall, the problem has since spread to 24 states. Commercial beekeepers are reporting losses of between 50 and 90 percent, an unprecedented amount even for an industry accustomed to die-offs.
Many worry that what's shaping up to be a honeybee catastrophe will disrupt the food supply. While staple crops like wheat and corn are pollinated by wind, some 90 cultivated flowering crops ? from almonds and apples to cranberries and watermelons ? rely heavily on honeybees trucked in for pollinization. Honeybees pollinate every third bite of food ingested by Americans, says a Cornell study. Bees help generate some $14 billion in produce.
Research is only beginning and hard data is still lacking, but beekeepers suspect everything from a new virus or parasite to pesticides and genetically modified crops. Scientists have hastily established a CCD working group at Pennsylvania State University. Last week, the US House of Representatives' Committee on Agriculture held hearings on the missing bees.
For many entomologists, the bee crisis is a wake-up call. By relying on a single species for pollination, US agriculture has put itself in a precarious position, they say. A resilient agricultural system requires diverse pollinators. This speaks to a larger conservation issue. Some evidence indicates a decline in the estimated 4,500 potential alternate pollinators ? native species of butterflies, wasps. and other bees. The blame for that sits squarely on human activity ? habitat loss, pesticide use, and imported disease ? but much of this could be offset by different land-use practices.
Moving away from monoculture, say scientists, and having something always flowering within bee-distance, would help natural pollinators. This would make crops less dependent on trucked-in bees, which have proved to be vulnerable to die-offs.
The stress on honeybees grew as native and wild pollinators diminished and farmers came to rely more on honeybees. We've put "all of our pollination eggs in the honeybee basket," says Mace Vaughan, conservation director of the Xerces Society for Invertebrate Conservation in Portland, Ore. "We need more baskets."
An immune-system disorder?
Meanwhile, beekeepers are seeing hives empty in a matter of weeks, sometimes days. The entire adult bee population vanishes, except for a few juveniles. This makes CCD difficult to study. "You have a crime scene, you know a crime happened here, but you don't really have evidence," says Medhat Nasr, provincial apiculturalist in Alberta, Canada. Eerily, the stored honey in the hive remains untouched. Raiding bees from nearby colonies never materialize, as is common.
Records of suddenly empty hives go back as far as the late 1800s, but never on this scale. Beekeepers dubbed it "autumn collapse," "spring dwindle," or "disappearing disease." But Dennis vanEngelsdorp, the acting Penn State apiarist, calls this manifestation the AIDS of bees. The remaining juvenile bees appear to be rife with disease. To him, "It's clear that there is an immune suppression," he says.
What might suppress a bee's immune system is anyone's guess. But many ascribe to a tipping-point theory: A variety of factors may have accumulated until a single straw finally broke the bee's back.
A review of honeybee history shows many suspects. The Varroa mite, native to Asia, came to North America in the late 1980s. Since then, yearly losses of between 15 and 20 percent have become the norm. "Before the mites, you could be a bee-have-er," says Mr. vanEngelsdorp. "Now you have to be a bee-keep-er."
Beekeepers are the first to acknowledge the stress of migratory pollination. Carted on flatbed trucks from wintering sites in the South, the bees crisscross the continent, first to California's almond groves, which rely entirely on honeybees for pollination, and then northward throughout the country, following the spring flowering season. Farmers have come to rely increasingly on honeybee services, says May Berenbaum, head of the department of entomology at the University of Illinois, Urbana-Champaign. "Given its economic importance, beekeeping really hasn't gotten the attention it deserves," she says.
Poor nutrition may be another factor, says Mr. Vaughan. To prepare them for winter, bees are fed high-fructose corn syrup and protein supplements. In the fields they've pollinated, meanwhile, more often than not they've gathered only one kind of pollen. Maybe, like other animals, they need a diverse diet, he says. "If you only ate McDonald's every day, you'd be just like that guy in 'Super Size Me,' " he says. "And he didn't feel that good."
Others, like Doan, suspect pesticides.
Similar problem in 1990s France
In the 1990s, France experienced a precipitous honeybee decline from "mad bee disease." Honey production dropped by nearly one-third, to 25,000 tons. French beekeepers blamed a newly introduced pesticide marketed under the name Gaucho. From the same family as nicotine, the chemical targeted aphids' navigational systems. And when the honeybees weren't finding their way home, either, French beekeepers protested. The French government banned the product in 1999. Though subsequent studies haven't found a strong link, bee populations still haven't rebounded to previous levels.
Others point to genetically modified crops ? specifically, those with a gene for a bacterial toxin called Bt. Initial studies indicated that it didn't affect bees. But some beekeepers argue the trials didn't last long enough to determine the long-term effects. (Doan says the same about the nicotinelike pesticides.) A German study supports this. Scientists at the University of Jena found that while Bt food had no direct effect on bees, when fed to bee populations infected with parasites, they quickly became diseased. Alone, Bt may do nothing. But in the presence of a parasite, it may facilitate infection.
"Maybe these toxins weaken the immune system," says John McDonald, a retired biologist and hobby apiculturalist in Spring Mills, Pa., who wrote an editorial on the topic for the San Francisco Chronicle
But the shrinking of our so-called "pollination portfolio" is of more concern to many entomologists than a die-off in commercial beehives. A 2006 National Academy of Sciences report declared that there was "direct evidence for decline of some pollinator species in North America" ? species responsible for pollinating three-quarters of flowering plants. Europeans have documented a parallel decline in their natural pollinators for years.
On the US East Coast, where a more ecologically diverse farming landscape enhances species diversity, studies have shown that wild pollinators were doing about 90 percent of the pollinating anyway, says Neal Williams, an assistant professor of biology at Bryn Mawr College in Pennsylvania. "It seems a little bit silly from a whole-country perspective, even from a farmer perspective, that we would place so much emphasis on one species. We don't do that with any other part of the economy," he says.
Meanwhile, a Canadian study suggests that if canola farmers leave 30 percent of their land fallow, they will increase their yields. Wild land provides habitat for native pollinators, improving pollination and increasing the number of seeds. "If we cultivate all the land, we lose ecosystem services like pollination," says Lora Morandin, lead author on the study. "Healthy, sustainable agricultural systems need to include natural land."

As a foot note, thanks to the efforts of everyone who submitted comments, it
looks like the release of impatiens will not be allowed at this stage. CDFA
has yet to officially respond to the submitted comments but the feeling is that
the Negative Declaration will not be issued. The large number of submissions
against the release and the significance of the issues raised in these
submissions will likely mean a more detailed and extensive Environmental Impact Report
will be required under CEQA.

What's Happening To The Bees?
April 4, 2007
_____
(Christian Science Monitor) This article was written by Moises
Velasquez-Manoff.
_____
Beekeeper James Doan first began finding empty hives last fall. Entire bee
colonies seemed to have up and vanished, leaving their honey behind. Noting
the unusually wet fall in Hamlin, N.Y., he blamed the weather. Unable to
forage in the rain, the bees probably starved, he reasoned.
But when deserted hives began appearing daily, "we knew it was something
different," he says. Now, at the beginning of the 2007 pollination season,
more than half of his 4,300 hives are gone. "I'm just about ready to give
up," says Doan from his honeybee wintering site in Ft. Meade, Fla. "I'm not
sure I can survive."
The cause of the die-offs has yet to be determined. Its effect on the food
supply may be significant. Longer-term, it may also force a rethinking of
some agricultural practices including our heavy reliance on human-managed
bees for pollination.
Scientists call it "colony collapse disorder" (CCD). First reported in
Florida last fall, the problem has since spread to 24 states. Commercial
beekeepers are reporting losses of between 50 and 90 percent, an
unprecedented amount even for an industry accustomed to die-offs.
Many worry that what's shaping up to be a honeybee catastrophe will disrupt
the food supply. While staple crops like wheat and corn are pollinated by
wind, some 90 cultivated flowering crops - from almonds and apples to
cranberries and watermelons - rely heavily on honeybees trucked in for
pollinization. Honeybees pollinate every third bite of food ingested by
Americans, says a Cornell study. Bees help generate some $14 billion in
produce.
Research is only beginning and hard data is still lacking, but beekeepers
suspect everything from a new virus or parasite to pesticides and
genetically modified crops. Scientists have hastily established a CCD
working group at Pennsylvania State University. Last week, the U.S. House of
Representatives' Committee on Agriculture held hearings on the missing bees.
For many entomologists, the bee crisis is a wake-up call. By relying on a
single species for pollination, U.S. agriculture has put itself in a
precarious position, they say. A resilient agricultural system requires
diverse pollinators. This speaks to a larger conservation issue. Some
evidence indicates a decline in the estimated 4,500 potential alternate
pollinators - native species of butterflies, wasps. and other bees. The
blame for that sits squarely on human activity - habitat loss, pesticide
use, and imported disease - but much of this could be offset by different
land-use practices.
Moving away from monoculture, say scientists, and having something always
flowering within bee-distance, would help natural pollinators. This would
make crops less dependent on trucked-in bees, which have proved to be
vulnerable to die-offs.
The stress on honeybees grew as native and wild pollinators diminished and
farmers came to rely more on honeybees. We've put "all of our pollination
eggs in the honeybee basket," says Mace Vaughan, conservation director of
the Xerces Society for Invertebrate Conservation in Portland, Ore. "We need
more baskets."
An immune-system disorder?
Meanwhile, beekeepers are seeing hives empty in a matter of weeks, sometimes
days. The entire adult bee population vanishes, except for a few juveniles.
This makes CCD difficult to study. "You have a crime scene, you know a crime
happened here, but you don't really have evidence," says Medhat Nasr,
provincial apiculturalist in Alberta, Canada. Eerily, the stored honey in
the hive remains untouched. Raiding bees from nearby colonies never
materialize, as is common.
Records of suddenly empty hives go back as far as the late 1800s, but never
on this scale. Beekeepers dubbed it "autumn collapse," "spring dwindle," or
"disappearing disease." But Dennis vanEngelsdorp, the acting Penn State
apiarist, calls this manifestation the AIDS of bees. The remaining juvenile
bees appear to be rife with disease. To him, "It's clear that there is an
immune suppression," he says.
What might suppress a bee's immune system is anyone's guess. But many
ascribe to a tipping-point theory: A variety of factors may have accumulated
until a single straw finally broke the bee's back.
A review of honeybee history shows many suspects. The Varroa mite, native to
Asia, came to North America in the late 1980s. Since then, yearly losses of
between 15 and 20 percent have become the norm. "Before the mites, you could
be a bee-have-er," says vanEngelsdorp. "Now you have to be a bee-keep-er."
Beekeepers are the first to acknowledge the stress of migratory pollination.
Carted on flatbed trucks from wintering sites in the South, the bees
crisscross the continent, first to California's almond groves, which rely
entirely on honeybees for pollination, and then northward throughout the
country, following the spring flowering season. Farmers have come to rely
increasingly on honeybee services, says May Berenbaum, head of the
department of entomology at the University of Illinois, Urbana-Champaign.
"Given its economic importance, beekeeping really hasn't gotten the
attention it deserves," she says.
Poor nutrition may be another factor, says Vaughan. To prepare them for
winter, bees are fed high-fructose corn syrup and protein supplements. In
the fields they've pollinated, meanwhile, more often than not they've
gathered only one kind of pollen. Maybe, like other animals, they need a
diverse diet, he says. "If you only ate McDonald's every day, you'd be just
like that guy in 'Super Size Me,' " he says. "And he didn't feel that good."
Others, like Doan, suspect pesticides.
Similar problem in 1990s France
In the 1990s, France experienced a precipitous honeybee decline from "mad
bee disease." Honey production dropped by nearly one-third, to 25,000 tons.
French beekeepers blamed a newly introduced pesticide marketed under the
name Gaucho. From the same family as nicotine, the chemical targeted aphids'
navigational systems. And when the honeybees weren't finding their way home,
either, French beekeepers protested. The French government banned the
product in 1999. Though subsequent studies haven't found a strong link, bee
populations still haven't rebounded to previous levels.
Others point to genetically modified crops - specifically, those with a gene
for a bacterial toxin called Bt. Initial studies indicated that it didn't
affect bees. But some beekeepers argue the trials didn't last long enough to
determine the long-term effects. (Doan says the same about the nicotinelike
pesticides.) A German study supports this. Scientists at the University of
Jena found that while Bt food had no direct effect on bees, when fed to bee
populations infected with parasites, they quickly became diseased. Alone, Bt
may do nothing. But in the presence of a parasite, it may facilitate
infection.
"Maybe these toxins weaken the immune system," says John McDonald, a retired
biologist and hobby apiculturalist in Spring Mills, Pa., who wrote an
editorial on the topic for the San Francisco Chronicle
But the shrinking of our so-called "pollination portfolio" is of more
concern to many entomologists than a die-off in commercial beehives. A 2006
National Academy of Sciences report declared that there was "direct evidence
for decline of some pollinator species in North America" - species
responsible for pollinating three-quarters of flowering plants. Europeans
have documented a parallel decline in their natural pollinators for years.
On the U.S. East Coast, where a more ecologically diverse farming landscape
enhances species diversity, studies have shown that wild pollinators were
doing about 90 percent of the pollinating anyway, says Neal Williams, an
assistant professor of biology at Bryn Mawr College in Pennsylvania. "It
seems a little bit silly from a whole-country perspective, even from a
farmer perspective, that we would place so much emphasis on one species. We
don't do that with any other part of the economy," he says.
Meanwhile, a Canadian study suggests that if canola farmers leave 30 percent
of their land fallow, they will increase their yields. Wild land provides
habitat for native pollinators, improving pollination and increasing the
number of seeds. "If we cultivate all the land, we lose ecosystem services
like pollination," says Lora Morandin, lead author on the study. "Healthy,
sustainable agricultural systems need to include natural land."

MAJOR JOB ACTIVITIES: Under the direction of the Xerces Society Executive Director and local U.S. Fish and Wildlife Service staff the Research Associate will conduct a detailed ecological study of the Laguna Mountain skipper. The following questions will be addressed: 1) Where in the habitat, and on which plants, do adult females oviposit? (2) What are the vegetation characteristics of oviposition areas? (3) What is the larval behavior (if caterpillars are found)? (4) Do pupae eclose synchronously or over a more protracted period? (5) What is the duration of the flight season and is the subspecies uni- or bi-voltine?. The Research Associate will also conduct order of magnitude population estimates using modified Pollard walks. The successful applicant will be trained in butterfly monitoring and research techniques.
Start Date: Early May 2007.
The ideal candidate will demonstrate the following:
Ability to reliably work independently in the field after an initial training.
Possess a valid driver?s license.

POLLINATION BEES BUTTERFLIES STAMP CROP ART BATS KANSAS MONARCH
Contact Information Available for logged-in reporters only
DescriptionA noted butterfly researcher and a world-famous crop artist are
behind a nationwide campaign to publicize the peril faced by species that
transfer pollen between flowers -- vital for much of our food supply. Crop art and a
postage stamp will help raise awareness of the damage pesticides and
pollution are doing to habitats of pollinators like bees, butterflies and bats.
Newswise ? Humans are reducing numbers of pollinators like bees and
butterflies by destroying habitats, spraying pesticides and emitting pollution. Now, a
University of Kansas researcher and a world-famous crop artist are behind a
nationwide campaign to publicize the peril faced by species that transfer pollen
between flowers.
?This is serious,? said Orley ?Chip? Taylor, professor of ecology and
evolutionary biology at KU. ?We?re losing six thousand acres of habitat a day to
development, 365 days a year. One out of every three bites you eat is
traceable to pollinators? activity. But if you start losing pollinators, you start
losing plants.?
Taylor works with the North American Pollinator Protection Campaign (NAPPC).
That group has successfully worked with the United States Department of
Agriculture and U.S. Senate to designate June 24 through June 30, 2007, as ?National
Pollinator Week.? The NAPPC also has convinced the United States Postal
Service to issue a block of four ?Pollination? stamps this summer depicting a
Morrison?s bumble bee, a calliope hummingbird, a lesser long-nosed bat and a
Southern dogface butterfly.
To call more attention to pollinators at risk, Taylor has enlisted help from
noted Kansas-based artist Stan Herd. Herd executes masterful large-scale
earthworks around the world, including rock mosaics, natural-material sculptures
and crop art.
?I sent Stan Herd an e-mail and said, ?Hey, we?ve got a project here I?d
like to have you think about?,? said Taylor. ?Stan immediately said ?yes.? He?
s very much aware of ecological issues and he wants to become involved.?
Herd will take an image from one ?Pollinator? stamp ? the Southern dogface
butterfly ? and create a vast facsimile at Pendleton?s Country Market, a
family farm between Kansas City and Lawrence. The image will be best viewed
aerially from a nearby silo or an aircraft. Herd?s immense stamp reproduction is to
incorporate plants that conservationists urge for use in backyard butterfly
gardens.
?I wanted to add my artistic statement to the equation,? said Herd. ?I?m a
fan of the flora and fauna and know that with migratory critters like
butterflies there are increasing problems because of loss of habitat. My work is about
my ideals. It also catches young people?s attention and we?ll bring school
kids out to get involved in this piece.?
Taylor and NAPPC are grateful for the awareness Herd?s work could bring to
the drop in pollinator populations.
?We can use this larger image to attract the attention of the public to this
cause,? said Laurie Adams, who manages NAPPC. ?Beautiful green lawns are
wonderful but we need to do more with our cities, farms and the habitats that we
control to provide for wildlife. Creating pollinator gardens or Monarch
butterfly waystations through MonarchWatch are easy to do. And they are important.?
Artist Herd plans to complete the pollinator stamp piece by National
Pollinator Week. Those wishing to make a tax-deducatble donation to the crop art
project can do so at the not-for-profit Coevolution Institute which coordinates
NAPPC at http://www.pollinator.org (click ?Crop Art Donations?) or by

Colony Collapse Disorder
One day you peer into the hive and all is well. On your next visit,
all that's left of a thriving colony are the queen and a handful of
bees around her. Last week, the House Agriculture Subcommittee on
Horticulture and Organic Agriculture had a hearing on the latest
threat to our pollinating bee population, "CCD," or Colony Collapse
Disorder. There's still a lot of mystery surrounding CCD, but area
beekeepers have been keeping a close watch on their hives. I met Marc
Hoffman with the Montgomery County Beekeepers Association at Brookside
Nature Center in Wheaton. Standing next to a group of hives run by the
Association, we talked about what "CCD" might mean for the region's
pollinators.

April 7, 2007
BANGOR, Maine --Maine blueberry growers expect to pay higher prices for
honeybees to pollinate their fields this spring following a die-off of bees
across the country.
Maine's blueberry crop requires about 50,000 beehives for pollination each
year, with most of the hives brought to Maine from other states.
Spencer Allen of Allen's Wild Maine Blueberries in Blue Hill said he usually
imports about 1,200 hives for 800 acres of crops.
Allen said his bee wrangler's bees are doing OK, but the national shortage
of honeybee pollinators is causing prices to go up. The price he will pay
has risen from about $50 to $70 -- a jump of 40 percent -- for each hive
placed in his fields, usually in mid-May.
"That adds up with 1,200 hives," Allen said.
Commercial beekeepers in 26 states have reported that they have lost between
50 and 90 percent of their bees to an unidentified disease. Scientists say
the country's food supply may be at risk if die-off continues unabated.
Maine beekeepers have several thousand hives that are kept in the state
year-round to pollinate apple orchards, strawberry fields and other crops.
But there aren't enough to cover Maine's 60,000 acres of blueberry fields.
Marc Plaisted of Pittston has raised honeybees for 20 years and supplies
hives to a dozen Maine farmers for pollination.
By time mid-May rolls around, he thinks the price could be $90 or more per
hive. Many migratory bee keepers are being lured to California, he said,
where almond growers are paying as much as $200 a hive.
But Plaisted's bigger concern is making sure the disease doesn't come to
Maine.
"We aren't seeing this disease here yet, but I'm very concerned about the
migratory bees that are brought into Maine," he said. "Who knows what
diseases they are bringing in here. If this disease is not here by the end
of summer, I'd be very surprised."
Nat Lindquist of Jasper Wyman and Sons of Milbridge, one of the state's
largest blueberry companies, said he will import 10,000 hives from seven
beekeepers. Lindquist began monitoring the bee kill last fall when his
largest supplier began reporting empty hives in Pennsylvania.
That beekeeper has lost more than a million bees. The bees in 2,000 of his
2,900 hives have disappeared -- a 60 percent loss.
"He has assured us that we will have plenty of bees," Lindquist said. "We
also want strong hives, and he has assured us of that as well."

Troubled ecosystem?: Smokies may feel heat of global warming

The flower of ?Rugelia,? which is in the Aster family, is the only member of
its genus. Its entire world range is within Great Smoky Mountains National
Park at high elevations.
By Mark Boxley
of the Daily Times Staff
Climate conditions in the Great Smoky Mountains National Park have never been
something stable enough to make a safe bet on. But things appear to be on the
verge of a pretty serious change, one that could alter the Park's ecosystem
forever.
Think of the ecosystem in the Smokies as a pyramid where animals, plants and
insects that need warmer temperatures live in low elevations at the bottom,
and organisms that need colder temperatures live higher up until you reach the
top.
If temperatures rise in the Park ? and, according to Keith Langdon, inventory
and monitoring coordinator with the Smokies, many scientific models indicate
they likely will in the next few decades ? the living things at the bottom
could, in theory, move up the mountain according to their needs. Trees, animals
and insects at the top, though, don't have the same options, and that's a big
problem.
"As you go uphill, as you go towards Clingman's Dome, you find fewer species
per same unit of area," Langdon said. "When you get near the top, most of the
species you find will be endemics ? that is, species with a very small range."
One of those would be the Frasier Fir tree, "which is quite rare outside
of the park," he said. "Three quarters of all its range is in the park.
"One of the worries that the Park has is that these endemics which are
clustered and reefed around the summits of our higher slopes, whether they will be
quote-un-quote, squeezed off the top of the mountains," he said. "And we're
worried about that.
"We are presuming, maybe incorrectly, that things at lower elevations might
be able to migrate up slope," he said. "We don't know that's true. But we know
there's no place for the ones on the very summit to migrate to."
There isn't any real hard data showing an amount of change in the Smokies
caused by climate change that most untrained eyes can see. But changes are there,
said GSMNP Chief of Resource Management and Science Nancy Finley.
"Yeah, I think we already have some clear indications that something is
different," she said.
"We have observed both a shift in some species that were never as far north
latitude-wise in the Smokies, in the Park," she said. "And we have seen species
that were never as high in elevation as they were before.
"In other words, if you hadn't seen something for years and you knew that
their northern-most extended range was Georgia, and all of a sudden you're seeing
them in the Smokies, there's something going on there," she said.
But the changes in the Park aren't as obvious as, say, acres of trees being
replaced by shrubbery.
"No, it's subtle," Finley said. "And I think that's why it's difficult for
people to understand or accept.
"It's not like you see a full-scale landscape change at this point," she
continued. "We're seeing a plant or a flower or a tree that you wouldn't
ordinarily have seen.
"At this point, we haven't seen an observed ecosystem-level change of any
sort, not even a population level change."
But give the climate change problem a few years, like maybe 10 or 15, and
then the story may be different, she said.
"I think you could potentially see a change in landscape," Finley said.
"Whether that's good, bad or indifferent is probably in the eyes of the beholder.
But it's clearly not what it was supposed to be."
Rapid change
Scientific data are usually things that can be interpreted differently
depending on the person looking at the figures. Climate change is certainly no
different.
But when it comes to climate modeling for the southeast United States, the
consensus seems to point to higher temperatures through the year 2100.
"When you look at the computer model simulations that have been run for the
rest of the century, I've seen three or four different ones, and they all call
for climate change," Langdon said. "There would be an impact to the park.
"Let me hasten to add, as they say, that the climate has never been stable ?
it's always changing," he said. "We've experienced warm temperatures
before."
The problem that seems to be approaching the Park today is not so much the
possibility of increased temperatures, but the rapidity of the change ? a couple
decades instead of a few centuries, Langdon said.
"I think some of the concerns I've heard expressed professionally is that
this change may occur very rapidly," he said. "Much more rapidly than species can
accommodate.
"So if (the species) need to migrate up slope a half mile to a different
climate, they can do that over a few hundred years," he added. "They may not be
able to do that over a few tens of years."

Pollination in danger
For trees and other plants that rely on an outside force to help during the
pollination period, climate change trouble could come in the form of something
as simple as an insect dying off or migrating due to a temperature increase.
And that is big trouble for the area plants.
"When a pollinator goes locally extinct, the plants that depend on that
pollinator, they're doomed," Langdon said.
There are, and probably always will be, experts and lay people who disagree
with the assertion that climate change is coming and that it could mean drastic
changes for the Smokies over the next 20 years of so. But Park officials are
looking at the data and are preparing for the worst, in hopes of getting out
in front of the problem before irreparable damage is inflicted upon the Smokies.
Ecosystem change due to climate change in the Smokies is not a certainty,
Langdon said, but the data certainly seems to be pointing in that direction.
"Nothing's ever 100 percent, nor should it be, but from what I've seen the
majority of the models predict temperature increase for the southeast states for
the rest of the century."

Butterfly art project may be sweet for bees
By Eric Weslander
Monday, April 9, 2007
An artwork envisioned for a patch of ground east of Lawrence will tell the
story of the birds and the bees - or at least, the butterflies and the bees.
Lawrence crop artist Stan Herd is collaborating with Kansas University in a
plan to raise awareness of the loss of habitat for pollinating animals by
building a 2-acre earthwork of a butterfly at Pendleton's Country Market
east of Lawrence.
The work should be finished by late June, in time for the U.S.
Senate-designated "National Pollinator Week" at the request of the North
American Pollinator Protection Campaign.
"I've always felt that artwork used properly was a platform for the
discussion of issues," said Herd, who is known internationally for his
large-scale artworks built into the landscape.
Herd became involved in the project at the request of Chip Taylor, KU
professor of ecology and evolutionary biology, who says that thousands of
acres of pollinating animals' habitat per day are lost to development.
Losing pollinating animals means losing a key part of the ecosystem, Taylor
said.
"All the seeds, fruits, nuts and vegetation of all the plants that are
supported by these pollinators is food for everything else," he said.
The earthwork, which will be made using thousands of petunias, will
replicate the southern dogface butterfly depicted on one of four
"pollination" stamps the U.S. Postal Service will issue this summer.
Taylor said he's trying to raise about $25,000 in coming weeks for the
project. Donations can be submitted online at www.pollinator.org or made by
contacting Laurie Adams at (415) 362-1137.

Safety Assessment of Bt Crops for Adult and Larval Honeybees
- by Eric Sachs, Yong Gao and Jian Duan, Presented March 29, 2007, Public
Hearing, Subcommittee on Horticulture and Organic Agriculture
Summary
--Entomologists have not been able to determine the cause of CCD (colony
collapse disorder) in honey bees. While the cause is not yet clear, there is
strong evidence that the production of specific insecticidal proteins from
the soil bacterium Bacillus thuringiensis (Bt) in crops to control targeted
caterpillar pests and beetles does not pose a risk to honeybees.
--There is extensive information on the lack of non-target effects to
diverse groups of beneficial insects including honey bees and other
pollinators from Bt microbial preparations that contain Bt proteins.
--Bt proteins are ideal for use in organic production and in Bt crops
because they bind specifically to receptors on the mid-gut of sensitive
caterpillar pests and have no deleterious effect on beneficial/non-target
insects under the conditions of use, including predators and parasitoids of
targeted caterpillar pests and honeybees.
--Scientists perform extensive honeybee safety assessments on all
insect-protected crops, including Bt corn and Bt cotton. The Bt proteins in
these crops have been shown to have no adverse effect on the honeybee.
--EPA risk assessments have demonstrated that Bt proteins expressed in Bt
crops do not exhibit detrimental effects to non-target organisms in
populations exposed to the levels of Bt proteins produced in plant tissues.
--Specific studies involving Cry1Ab provide strong evidence of the safety of
MON 810 Bt corn to the honeybee (similar studies have been conducted with
other Bt proteins in genetically modified crops).
--The EPA concluded that based on the weight of evidence there are no
unreasonable adverse effects of the Cry1Ab protein expressed in MON 810 Bt
corn to non-target wildlife or beneficial invertebrates.
Colony Collapse Disorder in Honey Bees
Because honey bees play such a crucial role in agriculture, the recent news
that large areas of the U.S. were experiencing a wide-spread sudden loss (or
disappearance) of honey bee colonies caused alarm across the country. This
phenomenon has been described by honeybee experts as Colony Collapse
Disorder (CCD). Groups critical of the widespread adoption of biotech crops
in the U.S. and globally have recently begun a campaign alleging that CCD
may be caused by crops expressing one or more Bt proteins. Unfortunately,
entomologists have not been able to determine the cause of CCD. While the
cause is not yet clear, there is strong evidence that the production of
specific insecticidal proteins from the soil bacterium Bacillus
thuringiensis (Bt) in crops to control targeted caterpillar pests and
beetles does not pose a risk to honeybees.
Safety of Commercialized Bt Proteins in Corn and Cotton
There is extensive information on the lack of non-target effects to diverse
groups of beneficial insects including honey bees and other pollinators from
Bt microbial preparations that contain Bt proteins. The Bt proteins produced
in Bt corn and Bt cotton are present in microbial products used in
agricultural systems to control targeted pests. Bt proteins are extremely
selective and are toxic only to specific pests . A generalized mode of
action for Bt proteins includes ingestion of the protein crystals by
insects, solubilization of the crystals in the insect midgut and proteolytic
processing of the released Bt protein by enzymes, and binding of the
partially digested "activated" protein to specific high-affinity receptors
on the surface of the midgut epithelium of target insects . Bt proteins are
ideal for use in organic production and in Bt crops because they bind
specifically to receptors on the mid-gut of sensitive caterpillar pests and
have no deleterious effect on beneficial/non-target insects, under the
conditions of use, including predators and parasitoids of targeted
caterpillar pests and honeybee (Apis mellifera) .
Safety Assessment of Bt Crops
Scientists perform extensive honeybee safety assessments on all
insect-protected crops, including Bt corn and Bt cotton. The Bt proteins in
these crops have been shown to have no adverse effect on the honeybee. EPA
evaluated studies of potential effects on a wide variety of non-target
organisms that might be exposed to the Bt protein, e.g., birds, fish,
honeybees, ladybugs, parasitic wasps, lacewings, springtails, aquatic
invertebrates and earthworms. Such non-target organisms are important to a
healthy ecosystem, especially the predatory, parasitic, and pollinating
insects . These risk assessments demonstrated that Bt proteins expressed in
Bt crops do not exhibit detrimental effects to non-target organisms in
populations exposed to the levels of Bt proteins produced in plant tissues.
To illustrate how the different Bt proteins produced in Bt crops are
evaluated for safety to the honeybee, two representative studies are
described below for the Cry1Ab protein produced in MON 810 Bt corn. These
studies with Cry1Ab protein were conducted with the trypsin-resistant core
because this is the insecticidally-active portion of the Cry1Ab protein.
Specific studies designed to assess the potential for adverse effects to
developing larval and adult honeybees are described below.
Honeybee Larva.
The primary route of exposure for honey bee larvae to the Cry1Ab protein is
ingestion of pollen collected by foraging adults from genetically modified
plants. Therefore, honey bee larvae were exposed to Cry1Ab protein in their
natural diet by including a maximum hazard dose (20 parts per million in
distilled water mixed with honey) in developing brood cells. This maximum
nominal concentration of 20 ppm was approximately 100 times greater than the
maximum expected Cry1Ab protein level in MON 810 pollen. In addition to this
treatment group, a negative control group was treated with distilled water.
Another control group was treated with heat-attenuated (inactivated) Cry1Ab
protein (20 ppm), and one set of larvae received no treatment (untreated
control). At least 50 bees (1 to 4 days old) were in each replicate, and
there were three replicates for each group. The treatments were administered
to each larval cell through an electronic micro-applicator, which delivered
5 microliters (?L) of the test diet. Once the first bee emerged on day 15,
daily counting of emerged bees was performed and emerged bees were removed
to an adult holding cage. The test diet was renewed daily and the study was
terminated 48 hours after the last bee had emerged on day 19.
There were no statistically significant (P>0.05) differences in honeybee
larval survival to adult emergence among the four treatment groups. The mean
adult survival rates after emergence ranged from 91.7% to 96.0% across all
groups, including the controls and Cry1Ab-treated groups. This study
demonstrates that honeybee larvae were not adversely affected after being
exposed to Cry1Ab protein at a concentration of 20 ppm in their diet.
Adult Honeybee.
Adult bees reared in bee hives were immobilized using CO2. The test diet was
prepared by mixing the appropriate amount of the insecticidally-active
Cry1Ab protein with a honey-water (50-50) syrup to a concentration of 20
parts per million (?g protein/g diet; ppm). The negative control group was
fed the same diet with the exception that no Cry1Ab protein was added to the
honey-water mixture. A second control group was fed heat-attenuated
(inactivated) Cry1Ab protein at the same concentration (20 ppm) as the
treatment group. A fourth test system was an empty cage to measure the
amount of diet loss due to evaporation. All diets were presented to the bees
in a 6 ml shell vial inserted through a cork in the holding cage lid. Three
replicates of four test groups of at least 40 adult honeybees were selected
and placed in each holding cage. Two observations were made the first day
and were made daily for the duration of the 9-day study. At the time of the
daily observation, the test diets were replaced with fresh vials containing
the appropriate concentration of test material. The test was terminated on
day 9 when the mortality rate in the negative control group exceeded 20%.
Adult honeybees exposed to the Cry1Ab protein in a honey-water solution for
9 days at a concentration of 20 ppm showed no signs of treatment-related
mortality or toxicity. At the end of the testing period, the mortality
percentage was calculated for each group. Mortality in the treatment and the
negative control groups was 16.20% and 22.28%, respectively. The
heat-attenuated control group mortality was 32.59%. Mortality showed a sharp
increase in all three groups from days 6 through 9. At the termination of
the test, the highest mortality was observed in the group that was fed the
heat-attenuated Cry1Ab protein diet, while the lowest mortality was observed
in the group that was fed the Cry1Ab protein diet. The mortalities in the
treatment group are not considered to be treatment-related because the two
control groups showed a higher percentage of mortality over the same time
interval. There was no significant statistical difference (P>0.05) in
mortality patterns between any of the groups.
The EPA concluded that based on the weight of evidence there are no
unreasonable adverse effects of the Cry1Ab protein expressed in MON 810 Bt
corn to non-target wildlife or beneficial invertebrates . They reported no
measurable deleterious effects were observed in submitted studies of the
Cry1Ab protein administered to honey bee larvae, honey bee adults, parasitic
wasps, Ladybird beetles, green lacewings, Collembola (springtails), and
Daphnia.

Subject: [Pollinator] Paul Harvey and Bees - Monday, April 16
Message-ID:
Thanks to Barry Thompson for this update - good day.
Paul Harvey, on his noon broadcast on Monday, April 16, had a lengthy piece
on CCD and its apparent reduction of honey bee populations "not only in the
United States" but Canada, Wales, and in multiple European countries. He included
the well-known Einstein comment that "when the bees disappear, the world has
about four years." Unfortunately, PH also mentioned the studies from Landau
(GE) regarding cell phone (transmission) disruption of honey bee orientation,
thereby giving credence to incompletely understood data (my opinion.) The
broadcast will not be available in text until 1315 EDT, so I can't pass on much that
is useful. Nonetheless, the "press" continues re "CCD". Research thus far
hasn't progress much toward definition of one or more etiologies. Losses continue
here in the East from a variety of circumstances (weather being no help
presently to the splitting of colonies for increase and replacement.)
42 degrees F. with winds to 50 mph here all night and morning; guess that I
won't attempt to open colonies today (but I'd better check to see if high water
or winds have dumped any over, exposing bees to inclement conditions.)
Regards,
Barry Thompson

Message-ID: <04dc01c782b9$551db780$3c06000a@cov002>
The North American Pollinator Protection Campaign (NAPPC) issued the following press release yesterday. It can also be found online at http://www.pollinator.org/Resources/CoECropArtPressReleaseFINAL.pdf.
FOR IMMEDIATE RELEASE

Will a Butterfly Bloom in Kansas?
San Francisco, CA (April 18, 2007) A bold plan to publicize the importance and plight of pollinators in the U.S. is hoping to literally take root on a small farm in Kansas. Backed by a continental coalition of pollinator advocates, a program to raise funds for a unique blend of art and conservation advocacy is looking for "seed money."
To draw attention to the importance of pollinators in ecosystems, agriculture, and biodiversity, a continent-wide campaign to protect pollinators, the North American Pollinator Protection Campaign (NAPPC), plans to partner with world-renowned Kansas-based crop artist Stan Herd to build a 50-foot butterfly out of natural materials.
"Pollinators are essential to our quality of life, and they may be in trouble," said Laurie Davies Adams, who directs the North American Pollinator Protection Campaign (NAPPC). "Many people don't realize that we depend on pollinators for 80% of the flowering plants in natural areas and for much of the food we eat. A world without pollinators is a world without strawberries, apples, almonds, berries, and even one-half of the oils in our diet."
Convinced that public awareness and involvement are essential to pollinator protection, NAPPC Steering Committee member Professor Chip Taylor of the University of Kansas, and the head of MonarchWatch, has enlisted the help of acclaimed artist Stan Herd to publicize the issue. Herd specializes in large-scale earthworks, such as crop art and rock mosaics, and has been featured in publications such as National Geographic, Smithsonian, and Wall Street Journal. His previous work can be viewed at www.stanherdart.com, and a sketch of the crop art is available at http://www.pollinator.org/pix/crop%20art%20sketch.jpg. (See below left.)
Herd plans to replicate one of four Pollination stamps to be issued by the U.S. Postal Service, the Southern dogface butterfly, using only plants and other natural materials. The installation will be executed near Pendleton's Country Market, a family farm off Kansas Highway 10 between Olathe and Lawrence. The resulting evanescent image will be viewed aerially for a brief few weeks. Flyovers originating from an airport three miles away are planned.
NAPPC hopes to raise the funding for this project this month - in time for planting. "Our goal is that the beauty and timeliness of this art inspire the public to take action to protect pollinators," said Taylor. "Small actions make a big difference at the collective level. Get in touch with nature by taking a walk; learn about animal-pollinated plants native to your area; and then plant a few. Another way to help is by donating to the pollinator crop art project, which will help bring much-needed publicity to the importance of pollinators."
The crop art will coincide with National Pollinator Week, designated by the U.S. Senate and the U.S. Department of Agriculture to help publicize the vulnerability of pollinators and to call on the public to create pollinator-friendly habitats in their own landscapes.
The U.S. Postal Service block of four Pollination stamps, to be issued during Pollinator Week, will feature Morrison's bumble bee, the calliope hummingbird, and the lesser long-nosed bat, in addition to the Southern dogface butterfly that crop artist Herd plans to create in flowers.
"We are excited that the message we are trying to convey - the importance of pollinators to our society - will be amplified with this enormous and unique reproduction of our beautiful postage stamp," said David Failor, Executive Director of Stamp Services for the U.S. Postal Service.
National Pollinator Week will focus on information on actions that help pollinators. Through habitat destruction, misuse of pesticides, and pollution, humans have provoked a decline in many species of pollinators, such as birds, bats, bees and butterflies that play an essential role in the reproduction of flowering plants both on farms and in the wild.
National Pollinator Week comes at a time when pollinators have been in the news. Recently, much media attention has been focused on the mysterious disappearance of tens of thousands of honey bee colonies, a phenomenon known as Colony Collapse Disorder (CCD). Scientists are currently studying the extent, causes and remedies for this unexplained loss, and have put forth possible explanations ranging from new pesticides to persistent drought caused by climate change to persistent and cumulative effects of parasites, disease or fungus. Whatever the reason, CCD has proven particularly difficult for the farmers who depend on honey bees to pollinate their crops.
"Everyone loses when we lose pollinators," said Paul Growald, the Chairman of NAPPC. "When pollinators are in trouble, the plant species that depend on them are in trouble - the entire ecosystem suffers. When beekeepers are forced to charge farmers more for pollination services because of honey bee die-off, we all shoulder the burden in the form of higher food prices."
To make a tax-deductible donation to the crop art project, visit www.pollinator.org (click "Crop Art Donations") or Contact Laurie Davies Adams at (415) 362-1137 or info at coevolution.org. Donations are necessary to assure the project's timely completion; artist Herd hopes to complete the pollinator crop art by National Pollinator Week, June 24-30. NAPPC encourages all types of groups - classrooms, congregations, families - and individuals to use this opportunity to learn about pollinators as they fundraise to support this project. NAPPC gratefully welcomes donations of any amount, and will recognize contributors on www.pollinator.org.

The buzz about mason bees
By Pam
Tempelmayr
Apr 20 2007
In Bloom
Have you noticed a shiny blue bee or what might look like a furry fly in
your garden or orchard?
Chances are you have seen an orchard mason bee, Osmia lignaria, and you must
consider yourself fortunate. These are one of the best pollinators you can
have. These insects are a type of honeybee usually a bit smaller in size than
the domesticated variety kept by beekeepers.
Females, unlike these honeybee counterparts, who have sacs on their legs for
collecting pollen, have hairs on the underside of their abdomens (called
scopa) for this purpose. Since their habit is to land on the top of blossoms they
are constantly transferring pollen as they move from blossom to blossom. I?ve
found their holes under the siding on our old shed as well as in the tree bark
on our property.
These holes in which females lay eggs are not anything to be concerned
about, as this fuzzy little bee doesn?t excavate at all. It actually cleans out
loose debris from existing holes. She picks holes about 1/4 to 3/8 inches (about
2 1/2 cm) in diameter and three to six inches (7 1/2 ? 15 1/4 cm) deep.
The first chore as pre-stated is cleaning out the hole, and then the bee
places a mud plug at the bottom. Into this she busily transfers 15 to 20 loads of
pollen and nectar, which provides food for her progeny. Once she has
sufficient stores she lays her egg and seals the cell with a tiny plug of mud. She
then supplies another cell the same way on and on until the hole is nearly
filled.
At this stage, she seals the entrance with another thick mud plug. This seal
is also important for your identification as some wasps and leaf-cutters also
lay in similar holes. The mason bee?s plug is always rough, while that of a
wasp is smooth and a leaf-cutters hole is sealed with chewed leaves.
Females live about one month laying about two eggs a day. Larva hatch from
egg after a few days and begin eating provisions. Once these are eaten (about
10 days) the larva spins a cocoon and pupates.
They remain in cocoon until spring. Males (smaller with long antennae)
emerge first then females emerge from inner cells a few days later, chewing through
cocoons and mud plugs. They begin nesting in three or four days. If weather
cools it might take one or two weeks for all bees to emerge.
Mason bees aren?t just great pollinators, they are totally non-aggressive
and rarely if ever sting and the sting is more like a mosquito bite.
Some gardeners I know have mason bee houses hanging under the eaves of the
shed next to fruit trees. They are simply made (or bought) by drilling holes
1/4 to 3/8 inches (about 21/2 cm) in diameter and three to six inches (about 7
1/2 ? 15 1/4 cm) deep into a piece of pine or fir. I?m told a ?brad-point bit?
makes a nice smooth hole. These houses are about a foot (1/3 metre) high and
half that width. They?ve cut the top to a point adding two little pieces of
molding to look like a peaked roof for decorative effect. They are hung under
the eaves for rain protection. It is also important they catch the sun?s
morning rays and there is a source for mud making nearby.
Tip: About 80 per cent of the world?s crops require pollination from birds,
bees, butterflies, beetles, mosquitoes and bats. June 24-30 this year is
International Pollinator Week and the U. S. Postal Service is issuing a booklet of
20 commemorative stamps on June 24th titled Pollination (by artist Steve
Buchanan) in honour of it.
Superstition: Bathe in warm water and honey to attract love.

Flowers Evolve to Suit Birds and Bats
By Heather Whipps
Special to LiveScience
posted: 20 April 2007
11:37 am ET
The varying shapes of flowers found in tropical forests, from broadly
blooming to delicately narrow, may have to do with what has stuck its nose in there
to pollinate in past evolutionary eras. ?
Different species of birds and bats may have encouraged flowers to evolve to
fit the shape of their snouts or beaks, new findings suggest. ?
Flowers seem to respond to whatever is available and doing the best job of
spreading pollen, said study leader Nathan Muchhala, a University of Miami
biologist. Birds and bats have also changed their body shapes over time to adapt
to available food sources and flower and plant shapes, but flowers have done so
more aggressively, he said. ?
"Basically, the flowers are making an evolutionary decision," he told
LiveScience. "Organisms can specialize in something (like having wide or narrow
openings), but they have to make the tradeoff to be good at one or the other." ?
The findings are detailed in this month's issue of the American Naturalist.
?
If the snout fits ?
Biologists have long observed that pollinators such as birds and bats seem
to favor different shapes and species of flowers. However, there has never been
evidence to support the idea that flower diversity is a direct result of the
need to "choose" one shape over another depending on the pollinator. ?
To test this, Muchhala and his team captured (and later released) a species
of nectar bat and hummingbird in the rainforests of Ecuador and brought them
together with a variety of artificial flowers?filled with honey water?like the
ones found locally. ?
Flower-pollinator fit was crucial in successful pollination, the results
showed. ?
The hummingbirds, with their long and thin beaks, were better guided by
flowers with similarly narrow shapes. On the other hand, the much larger bats made
better contact with flowers that had wider openings. ?
Lots of pollen dropped to the ground and was wasted by each animal when the
reverse was tested, Muchhala said, and also forced the animals to fly in at odd
?and probably uncomfortable?angles. ?
It has probably been a bit of a give and take relationship over the years,
Muchhala said, with the flowers doing most of the evolutionary work. ?
"There is definitely some degree of co-evolution (simultaneously adapting
together), which you can see just in the fact that flower visiting bats and
birds have longer snouts than other bats and birds," he said. "However, flowers
seem to respond faster." ?
There isn't just one flower species per bat or bird, Muchhala clarified. ?
"This is a common misconception?that is, that each flower has its bat/bird
specialist, and they are tightly interdependent," he said. "The one exception
is a bat with an extremely long tongue (140 percent of body length!) that I
recently discovered in Ecuador?a flower with a matching tube length is
exclusively specialized to this bat," he said. ?

Subject: [Pollinator] Bumble bees in the news
Message-ID:
>From My Mother Lode News:
Bumblebees Are Primo Pollinators
Saturday, April 21, 2007 - 06:00 AM
Bumblebees greet spring with unrestrained exuberance, appearing to gleefully
romp from one poppy blossom to the next.
In reality, these bees are hard at work, diligently gathering pollen and
nectar to take home to their nest. In so doing, they move pollen from one flower
to another to help produce yet another crop of next year's flowers, seed, and
food. Bumblebees are primo pollinators.
WHO ARE THE BUMBLEBEES? Bumblebees are large, hairy, yellow and black bees
that boisterously buzz flowers from early spring to late fall. There are about
240 species of Bombus worldwide with 26 native to California.
Due to their hairiness, bumblebees look larger than they really are. Their
hair helps gather and hold pollen during their travels from flower to flower,
and helps warm them during cold weather. They also have the ability to shiver
for warmth and, unlike honeybees and a number of other pollinators, can fly
from near freezing weather to into the 90s. Further, many bumblebees have
unusually long tongues enabling them to reach the inner parts of flowers other bees
cannot. And, they increase crop production by buzz pollinating (sonicating)
tomatoes, blueberries, eggplants, and some pepper blossoms.
Unlike social honeybees that form large hives, bumblebees are semi-social. A
single female starts a colony in the spring in an abandoned rodent hole or
tree cavity. By season's end, the nest may contain only 50 to 250 bees. All of
the bumblebees then die except a single fertilized female, who starts a new
colony in the spring. Since they don't over-winter in the colony, bumblebees do
not stockpile honey as do honeybees.
A garden or yard can easily house a bumblebee nest, perhaps several, without
your even knowing. Since bumblebees live in small nests, they never swarm.
And, since they produce only small amounts of honey for their own needs,
bumblebees have no need to protect their hives from honey thieves. Although a
bumblebee can sting more than once, they are quite unlikely to attack humans unless
their life is threatened. In fact the smaller male drones that hatch in
midsummer have no sting at all.
Don't confuse bumblebees with carpenter bees. Carpenter bees belong to the
species Xylocopa, and resemble bumblebees in size and shape, but their abdomen
or tail portion is usually a non-hairy shiny blue black. Carpenter bees are
solitary bees that bore holes in wood to make nests for their young. They are
valuable pollinators for some crops, but unlike many bumblebees, they are nectar
thieves that cut into the side of flowers and steal nectar, often without
pollinating.
THE PLIGHT OF NATIVE POLLINATORS: Pollinators are crucial to our food
supply. Without pollinators, we will lose most fruit crops, many vegetables and
grains, even chocolate. Honeybees (non-native European bees) are our best-known
pollinators, and their decline due to disease, mites, and ?colony collapse? has
received much press.
Fortunately we have 1,600 species of known California bees, including
bumblebees, plus many other native pollinating insects, bats, and birds. These
native creatures often have greater resistance to local diseases and parasites, and
their diversity makes it less likely that a disease would impact all.
Even so, our native pollinators are under a siege that has been compared to
global warming. The advent of chemical gardening and increased agriculture
last century took a great toll. Industrialization and urbanization continue to
reduce nesting areas and eliminate many native plants that pollinators depend
on. And, ongoing importation of exotic (non-native) bees, including European
bumblebees for greenhouse tomato pollination, potentially brings more new
diseases.
WHAT TO DO: We all have the power to help bumblebees and other pollinators
in some way. Embrace non-chemical solutions to pest problems and eliminate
pesticide powders and dusts, as pollinators can carry these back to the nest.
Encourage schools, parks, golf courses, and other public entities to use fewer
pesticides and to let ditches and hedgerows go unplowed and unsprayed to preserve
nesting sites. Let native plants (including some weeds) grow undisturbed
whenever possible.
And, if you can, plant a few pollinator flowers or even a pollinator garden.
Pollinators prefer their flowers in patches, rather than single plants, and
need a succession of blossoms from spring through fall.
The California Native Plant Society recommendations include California
poppies, sunflowers, lupine, clover, California lilac, penstemon, gooseberries,
salvias, milkweeds, and manzanita. For more flower suggestions, go to
http://nature.Berkeley.edu/urbanbeegardens. Also visit The American Pollinator Protection
Campaign at www.nappc.org.
A final word on bumblebees: Be sure to spend lots of time watching these
amazing creatures. Note which flowers they frequent. Teach children to enjoy
their antics and appreciate their contributions to our food supply. Slowly walk
away if bees fly too close. Remember, if undisturbed, bumblebees are peaceful
bees, very unlikely to sting.

Global changes fool Mother Nature
Arbor Day Foundation's new hardiness map reflects Earth's warming
By Nancy Taylor Robson
Special to The Sun
Originally published April 22, 2007
Does it seem as though your lilacs are opening earlier than they did in your
childhood? Have you noticed the dogwood, wild columbine and Virginia
bluebells blooming earlier?
It's not your imagination. Though there are certainly seasonal fluctuations
from year to year, as the recent cool spell can attest, studies are showing
global warming is having an effect on our gardens. "Many plants are blooming
weeks earlier than they used to," says David Inouye, professor of biology at the
University of Maryland, College Park.
A 30-year Smithsonian Institution study of first-flowering dates from Jan. 1
to June 1 in the Baltimore-Washington area shows distinct changes in bloom
times. Scientists tracked 2,500 species, then selected 100 for which they had
the most years of record.
"Of 100 species, 89 were flowering earlier," says Stanwyn Shet- ler,
emeritus curator of botany at Smithsonian Institution's National Museum of Natural
History. "From a fraction of a day to up to 46 days earlier."
The earlier warmth has prompted a recent revision in the hardiness map.
Using the temperature data from the National Oceanic and Atmospheric
Administration, the National Arbor Day Foundation revised the hardiness map to reflect the
fact that the South is creeping north.
The map has been adjusted twice before - once in 1965 to add data missing
from the original, and then again in 1990 to incorporate changes in weather
patterns.
This time, the changes are striking. Chunks of many states have warmed one
full hardiness zone. Some have even jumped two zones.
While Baltimore has stayed the same, Western Maryland has shifted from Zone
6 to Zone 7 and the Easton/Oxford/Cambridge area of the Eastern Shore has
moved from Zone 7 to Zone 8.
So what if spring comes earlier? Couldn't we just shift the cherry blossom
festival? Plant more Southern cultivars? What's the big deal? For one thing:
pollination. Just as with catching a plane, in the intricate dance of
plant-and-pollinator: Timing is everything.
"There is a rather tight schedule to meet, especially for forest-floor
flowers," Shetler says. "They can't come out too early or there aren't pollinators
there [to enable them to reproduce]. If they bloom too late, the canopy has
closed over and they don't get enough sun to go through their full cycle."
The pollinators have their own circadian clocks that determine emergence,
feeding and reproduction times that are not purely reliant on warmth. If bloom
time and pollen production don't coincide with pollinator emergence, insects
(and insect-eating birds) starve. Without pollinators, plants don't produce seed
or fruit.
Despite this critical connection, most gardeners rarely give pollination a
thought. "It's a service that's provided by ecosystems," Inouye says. "But
there has been growing concern over the past few years about the status of
pollinators in North America."
While home gardeners may blithely assume pollination will just happen,
commercial growers, keenly aware of their pollinator-dependence, often pay
commercial beekeepers to transport bees into orchards and farms to pollinate their
crops. But honeybees are suffering from colony collapse disorder, which kills off
as much as 60 percent of a hive in a winter.
Yet it isn't just a change in pollinators that will affect gardeners. Warmer
temperatures also have paved the way for a new crop of invasives coming up
from the south.
"When you shift minimum winter temperatures up, that acts as less of a brake
on where these invasives can grow," says Lewis Ziska, plant physiologist at
the U.S. Department of Agriculture's Crop Systems and Global Change Laboratory
in Beltsville.
Another spur to invasive weed growth is increased carbon dioxide (CO2)
levels, a key component of global warming. Since 1960, there has been a 20 percent
increase in CO2 levels outside of urban areas and a 24 percent increase in
Baltimore, Ziska says.
While plants require CO2 in addition to light, nutrients and water, when one
of the legs in that four-legged stool changes, it unbalances everything that
rests on them. In this case, plants that do well with higher CO2
concentrations multiply, while those that don't, die.
"Unfortunately, what we've seen is selection for invasives - Tree of Heaven,
Norway maple, [white] mulberry and invasive vines like [Japanese]
honeysuckle, morning glory, English ivy and kudzu, which we didn't have here 20 years
ago," Ziska says.
In addition to pollinator decline and invasive onslaught, plant colonies are
challenged by the weather extremes we're seeing now.
"When we have rain now, we have a lot of it," says Paul Babikow, president
of Babikow Greenhouses in Baltimore. "When we have drought, it lasts longer.
When we have a cold spell, it's really, really cold and then two weeks later, it
might be really, really warm. It's a lot more random than it used to be only
20 years ago."

Gecko Pollinators Help "Save" Rare Flower
Scott Norris
for National Geographic News
April 23, 2007
On the island of Mauritius
in the Indian Ocean, a brilliant green lizard and a palmlike shrub are
helping to save a rare flowering plant from extinction.
The naturally occurring conservation partnership features the lizard-a
species known as the blue-tailed day gecko-in an unusual role, researchers
say: The lizard is the key pollinator of the threatened Trochetia flower.
The shrubby Pandanus plant does its part by providing the lizard a safe
haven from predators as it performs pollinations, according to a new study.
Although insects also visited the Trochetia flowers, the research team found
that the bugs did not carry much pollen from one blossom to another, proving
the gecko is the main pollinator.
"An animal may visit flowers often, eating pollen or nectar, but not provide
a good pollination service," said study leader Dennis Hansen of the
University of Zurich in Switzerland.
"Our study is one of the few to provide evidence that lizards can indeed be
efficient pollinators."
Lizard Stand-In
Previously, a nectar-sipping bird called the olive white-eye pollinated
Trochetia, but the bird is nearly extinct.
Researchers say the flower's survival now largely depends on visits from the
5-inch-long (13-centimeter-long) gecko.
Like the birds, the geckos visit Trochetia plants to harvest nectar produced
by the flowers. In the process they transfer pollen from one blossom to
another.
But by venturing out on the exposed blossoms, geckos risk becoming lunch for
the Mauritian kestrel, a type of falcon that preys on lizards. Safety for
the gecko lies in dense, nearly impenetrable thickets of Pandanus plants
growing around the flowers.
Hansen's team found that Trochetia flowers growing close to Pandanus patches
received the lion's share of gecko visitations.
These flowers were able to bear fruit and reproduce, the researchers said,
while those located farther from Pandanus plants often did not.
The team's findings, which appear in the April edition of the journal The
American Naturalist, add to the growing number of examples of lizard
pollination.
So far, almost all known cases occur on oceanic islands.
Jens Olesen, of the University of Aarhus in Denmark, is an expert on the
little-studied phenomenon.
Olesen has assembled data showing that of more than 4,300 lizard species,
only 71 are known to feed on flower nectar and, in the process, provide
pollination services.
"Ninety-five percent of the flower-visiting lizard species are from
islands," Olesen said.
Olesen and colleagues have suggested that a shortage of insects for the
lizards to eat on remote islands may be what causes some species to become
fruit- and nectar-eaters.
And Joan Roughgarden, an ecologist at Stanford University in California,
thinks lizard pollination might evolve in island communities because
pollinating birds and insects are in short supply.
"Lizards are available and other pollinators are not," Roughgarden said.
"Bird faunas are usually [smaller] on islands, whereas lizards may be more
abundant than on the mainland."
(Related news:
"Buzz Kill: Wild Bees and Flowers Disappearing, Study Says" [July 21,
2006].)
Some island plants may even have special adaptations for attracting lizard
pollinators.
Nectar of a Different Color
Trochetia flowers on Mauritius had puzzled scientists by producing nectar
that is yellow or red in color. The nectar produced by almost all other
flowers is clear.
In a separate paper last year, Hansen and colleagues said they had solved
that mystery. Their experimental tests showed that colored nectar is an
effective lure for enticing geckos to visit blossoms.
Hansen's team is now studying another rare Mauritian flower that appears to
rely on geckos not only for pollination but also for seed dispersal.
"For both processes, the plants growing closer to Pandanus do better than
ones further away," Hansen said.
Similar chains of positive interactions involving cover-providing plants and
pollinating lizards may be widespread in island communities, he noted.
Maintaining such relationships may become increasingly important as native
bird pollinators continue to decline and disappear.
"For island conservation management, the major take-home message is the need
to promote habitat structural diversity, which provides [the foundation for]
lizard-mediated interactions."

Bees Vanish, and Scientists Race for Reasons
By ALEXEI BARRIONUEVO
BELTSVILLE, Md., April 23 - What is happening to the bees?
More than a quarter of the country's 2.4 million bee colonies have been lost
- tens of billions of bees, according to an estimate from the Apiary
Inspectors of America, a national group that tracks beekeeping. So far, no
one can say what is causing the bees to become disoriented and fail to
return to their hives.
As with any great mystery, a number of theories have been posed, and many
seem to researchers to be more science fiction than science. People have
blamed genetically modified crops, cellular phone towers and high-voltage
transmission lines for the disappearances. Or was it a secret plot by Russia
or Osama bin Laden
to bring down American agriculture? Or, as
some blogs have asserted, the rapture of the bees, in which God recalled
them to heaven? Researchers have heard it all.
The volume of theories "is totally mind-boggling," said Diana Cox-Foster, an
entomologist at Pennsylvania State
University. With Jeffrey
S. Pettis, an entomologist from the United States
Department of Agriculture, Dr.
Cox-Foster is leading a team of researchers who are trying to find answers
to explain "colony collapse disorder," the name given for the disappearing
bee syndrome.
"Clearly there is an urgency to solve this," Dr. Cox-Foster said. "We are
trying to move as quickly as we can."
Dr. Cox-Foster and fellow scientists who are here at a two-day meeting to
discuss early findings and future plans with government officials have been
focusing on the most likely suspects: a virus, a fungus or a pesticide.
About 60 researchers from North America sifted the possibilities at the
meeting today. Some expressed concern about the speed at which adult bees
are disappearing from their hives; some colonies have collapsed in as little
as two days. Others noted that countries in Europe, as well as Guatemala and
parts of Brazil, are also struggling for answers.
"There are losses around the world that may or not be linked," Dr. Pettis
said.
The investigation is now entering a critical phase. The researchers have
collected samples in several states and have begun doing bee autopsies and
genetic analysis.
So far, known enemies of the bee world, like the varroa mite, on their own
at least, do not appear to be responsible for the unusually high losses.
Genetic testing at Columbia University
has revealed the presence of
multiple micro-organisms in bees from hives or colonies that are in decline,
suggesting that something is weakening their immune system. The researchers
have found some fungi in the affected bees that are found in humans whose
immune systems have been suppressed by the Acquired Immune Deficiency
Syndrome or cancer
.
"That is extremely unusual," Dr. Cox-Foster said.
Meanwhile, samples were sent to an Agriculture Department laboratory in
North Carolina this month to screen for 117 chemicals. Particular suspicion
falls on a pesticide that France banned out of concern that it may have been
decimating bee colonies. Concern has also mounted among public officials.
"There are so many of our crops that require pollinators," said
Representative Dennis Cardoza, a California Democrat whose district includes
that state's central agricultural valley, and who presided last month at a
Congressional hearing on the bee issue. "We need an urgent call to arms to
try to ascertain what is really going on here with the bees, and bring as
much science as we possibly can to bear on the problem."
So far, colony collapse disorder has been found in 27 states, according to
Bee Alert Technology Inc., a company monitoring the problem. A recent survey
of 13 states by the Apiary Inspectors of America showed that 26 percent of
beekeepers had lost half of their bee colonies between September and March.
Honeybees are arguably the insects that are most important to the human food
chain. They are the principal pollinators of hundreds of fruits, vegetables,
flowers and nuts. The number of bee colonies has been declining since the
1940s, even as the crops that rely on them, such as California almonds, have
grown. In October, at about the time that beekeepers were experiencing huge
bee losses, a study by the National Academy of
Sciences questioned
whether American agriculture was relying too heavily on one type of
pollinator, the honeybee.
Bee colonies have been under stress in recent years as more beekeepers have
resorted to crisscrossing the country with 18-wheel trucks full of bees in
search of pollination work. These bees may suffer from a diet
that includes artificial
supplements, concoctions akin to energy drinks and power bars. In several
states, suburban sprawl has limited the bees' natural forage areas.
So far, the researchers have discounted the possibility that poor diet alone
could be responsible for the widespread losses. They have also set aside for
now the possibility that the cause could be bees feeding from a commonly
used genetically modified crop, Bt corn, because the symptoms typically
associated with toxins, such as blood poisoning, are not showing up in the
affected bees. But researchers emphasized today that feeding supplements
produced from genetically modified crops, such as high-fructose corn syrup,
need to be studied.
The scientists say that definitive answers for the colony collapses could be
months away. But recent advances in biology and genetic sequencing are
speeding the search.
Computers can decipher information from DNA
and match pieces of
genetic code with particular organisms. Luckily, a project to sequence some
11,000 genes of the honeybee was completed late last year at Baylor College
of Medicine in Houston, giving scientists a huge head start on identifying
any unknown pathogens in the bee tissue.
"Otherwise, we would be looking for the needle in the haystack," Dr.
Cox-Foster said.
Large bee losses are not unheard of. They have been reported at several
points in the past century. But researchers think they are dealing with
something new - or at least with something previously unidentified.
"There could be a number of factors that are weakening the bees or speeding
up things that shorten their lives," said Dr. W. Steve Sheppard, a professor
of entomology at Washington State
University. "The answer may
already be with us."
Scientists first learned of the bee disappearances in November, when David
Hackenberg, a Pennsylvania beekeeper, told Dr. Cox-Foster that more than 50
percent of his bee colonies had collapsed in Florida, where he had taken
them for the winter.
Dr. Cox-Foster, a 20-year veteran of studying bees, soon teamed with Dennis
vanEngelsdorp, the Pennsylvania apiary inspector, to look into the losses.
In December, she approached W. Ian Lipkin, director of the Greene Infectious
Disease Laboratory at Columbia University, about doing genetic sequencing of
tissue from bees in the colonies that experienced losses. The laboratory
uses a recently developed technique for reading and amplifying short
sequences of DNA that has revolutionized the science. Dr. Lipkin, who
typically works on human diseases, agreed to do the analysis, despite not
knowing who would ultimately pay for it. His laboratory is known for its
work in finding the West Nile
disease in the United
States.
Dr. Cox-Foster ultimately sent samples of bee tissue to researchers at
Columbia, to the Agriculture Department laboratory in Maryland, and to Gene
Robinson, an entomologist at the University of Illinois
. Fortuitously, she had frozen
bee samples from healthy colonies dating to 2004 to use for comparison.
After receiving the first bee samples from Dr. Cox-Foster on March 6, Dr.
Lipkin's team amplified the genetic material and started sequencing to
separate virus, fungus and parasite DNA from bee DNA.
"This is like C.S.I. for agriculture," Dr. Lipkin said. "It is painstaking,
gumshoe detective work."
Dr. Lipkin sent his first set of results to Dr. Cox-Foster, showing that
several unknown micro-organisms were present in the bees from collapsing
colonies. Meanwhile, Mr. vanEngelsdorp and researchers at the Agriculture
Department lab here began an autopsy of bees from collapsing colonies in
California, Florida, Georgia and Pennsylvania to search for any known bee
pathogens.
At the University of Illinois, using knowledge gained from the sequencing of
the bee genome, Dr. Robinson's team will try to find which genes in the
collapsing colonies are particularly active, perhaps indicating stress from
exposure to a toxin or pathogen.
The national research team also quietly began a parallel study in January,
financed in part by the National Honey Board, to further determine if
something pathogenic could be causing colonies to collapse.
Mr. Hackenberg, the beekeeper, agreed to take his empty bee boxes and other
equipment to Food Technology Service, a company in Mulberry, Fla., that uses
gamma rays to kill bacteria on medical equipment and some fruits. In early
results, the irradiated bee boxes seem to have shown a return to health for
colonies repopulated with Australian bees.
"This supports the idea that there is a pathogen there," Dr. Cox-Foster
said. "It would be hard to explain the irradiation getting rid of a
chemical."
Still, some environmental substances remain suspicious.
Chris Mullin, a Pennsylvania State University professor and insect
toxicologist, recently sent a set of samples to a federal laboratory in
Raleigh, N.C., that will screen for 117 chemicals. Of greatest interest are
the "systemic" chemicals that are able to pass through a plant's circulatory
system and move to the new leaves or the flowers, where they would come in
contact with bees.
One such group of compounds is called neonicotinoids, commonly used
pesticides that are used to treat corn and other seeds against pests. One of
the neonicotinoids, imidacloprid, is commonly used in Europe and the United
States to treat seeds, to protect residential foundations against termites
and to help keep golf courses and home lawns green.
In the late 1990s, French beekeepers reported large losses of their bees and
complained about the use of imidacloprid, sold under the brand name Gaucho.
The chemical, while not killing the bees outright, was causing them to be
disoriented and stay away from their hives, leading them to die of exposure
to the cold, French researchers later found. The beekeepers labeled the
syndrome "mad bee disease."
The French government banned the pesticide in 1999 for use on sunflowers,
and later for corn, despite protests by the German chemical giant Bayer,
which has said its internal research showed the pesticide was not toxic to
bees. Subsequent studies by independent French researchers have disagreed
with Bayer. Alison Chalmers, an eco-toxicologist for Bayer CropScience, said
at the meeting today that bee colonies had not recovered in France as
beekeepers had expected. "These chemicals are not being used anymore," she
said of imidacloprid, "so they certainly were not the only cause."
Among the pesticides being tested in the American bee investigation, the
neonicotinoids group "is the number-one suspect," Dr. Mullin said. He hoped
results of the toxicology screening will be ready within a month.

Disappearing Bees

By ALEXEI BARRIONUEVO
Published: April 24, 2007
BELTSVILLE, Md., April 23 ? What is happening to the bees?
More than a quarter of the country?s 2.4 million bee colonies have been lost
? tens of billions of bees, according to an estimate from the Apiary
Inspectors of America, a national group that tracks beekeeping. So far, no one can say
what is causing the bees to become disoriented and fail to return to their
hives.
As with any great mystery, a number of theories have been posed, and many
seem to researchers to be more science fiction than science. People have blamed
genetically modified crops, cellular phone towers and high-voltage
transmission lines for the disappearances. Or was it a secret plot by Russia or Osama bin
Laden to bring down American agriculture? Or, as some blogs have asserted,
the rapture of the bees, in which God recalled them to heaven? Researchers have
heard it all.
The volume of theories ?is totally mind-boggling,? said Diana Cox-Foster, an
entomologist at Pennsylvania State University. With Jeffrey S. Pettis, an
entomologist from the United States Department of Agriculture, Dr. Cox-Foster is
leading a team of researchers who are trying to find answers to explain ?
colony collapse disorder,? the name given for the disappearing bee syndrome.
?Clearly there is an urgency to solve this,? Dr. Cox-Foster said. ?We are
trying to move as quickly as we can.?
Dr. Cox-Foster and fellow scientists who are here at a two-day meeting to
discuss early findings and future plans with government officials have been
focusing on the most likely suspects: a virus, a fungus or a pesticide.
About 60 researchers from North America sifted the possibilities at the
meeting today. Some expressed concern about the speed at which adult bees are
disappearing from their hives; some colonies have collapsed in as little as two
days. Others noted that countries in Europe, as well as Guatemala and parts of
Brazil, are also struggling for answers.
?There are losses around the world that may or not be linked,? Dr. Pettis
said.
The investigation is now entering a critical phase. The researchers have
collected samples in several states and have begun doing bee autopsies and
genetic analysis.
So far, known enemies of the bee world, like the varroa mite, on their own
at least, do not appear to be responsible for the unusually high losses.
Genetic testing at Columbia University has revealed the presence of multiple
micro-organisms in bees from hives or colonies that are in decline,
suggesting that something is weakening their immune system. The researchers have found
some fungi in the affected bees that are found in humans whose immune systems
have been suppressed by the Acquired Immune Deficiency Syndrome or cancer.
?That is extremely unusual,? Dr. Cox-Foster said.
Meanwhile, samples were sent to an Agriculture Department laboratory in
North Carolina this month to screen for 117 chemicals. Particular suspicion falls
on a pesticide that France banned out of concern that it may have been
decimating bee colonies. Concern has also mounted among public officials.
?There are so many of our crops that require pollinators,? said
Representative Dennis Cardoza, a California Democrat whose district includes that state?s
central agricultural valley, and who presided last month at a Congressional
hearing on the bee issue. ?We need an urgent call to arms to try to ascertain
what is really going on here with the bees, and bring as much science as we
possibly can to bear on the problem.?
So far, colony collapse disorder has been found in 27 states, according to
Bee Alert Technology Inc., a company monitoring the problem. A recent survey of
13 states by the Apiary Inspectors of America showed that 26 percent of
beekeepers had lost half of their bee colonies between September and March.
Honeybees are arguably the insects that are most important to the human food
chain. They are the principal pollinators of hundreds of fruits, vegetables,
flowers and nuts. The number of bee colonies has been declining since the
1940s, even as the crops that rely on them, such as California almonds, have
grown. In October, at about the time that beekeepers were experiencing huge bee
losses, a study by the National Academy of Sciences questioned whether American
agriculture was relying too heavily on one type of pollinator, the honeybee.
Bee colonies have been under stress in recent years as more beekeepers have
resorted to crisscrossing the country with 18-wheel trucks full of bees in
search of pollination work. These bees may suffer from a diet that includes
artificial supplements, concoctions akin to energy drinks and power bars. In
several states, suburban sprawl has limited the bees? natural forage areas.
So far, the researchers have discounted the possibility that poor diet alone
could be responsible for the widespread losses. They have also set aside for
now the possibility that the cause could be bees feeding from a commonly used
genetically modified crop, Bt corn, because the symptoms typically associated
with toxins, such as blood poisoning, are not showing up in the affected bees.
But researchers emphasized today that feeding supplements produced from
genetically modified crops, such as high-fructose corn syrup, need to be studied.
The scientists say that definitive answers for the colony collapses could be
months away. But recent advances in biology and genetic sequencing are
speeding the search.
Computers can decipher information from DNA and match pieces of genetic code
with particular organisms. Luckily, a project to sequence some 11,000 genes
of the honeybee was completed late last year at Baylor College of Medicine in
Houston, giving scientists a huge head start on identifying any unknown
pathogens in the bee tissue.
?Otherwise, we would be looking for the needle in the haystack,? Dr.
Cox-Foster said.

Subject: [Pollinator] Whidbey hives collapse
Message-ID:
Whidbey News-Times
Whidbey hives collapse
By Paul Boring
Apr 25 2007
A scientifically baffling and poorly understood phenomenon causing bees
worldwide to drop like flies has made its way to Whidbey Island.
Tom Schioler, Greenbank beekeeper and the only commercial pollinator on the
island, recently lost at least two hives to what is widely referred to as
Colony Collapse Disorder.
The story began more than two months ago when the local beekeeper, despite
his most fervent efforts to save the bees, lost a hive to the unicellular
parasite Nosema.
?Nosema is basically bee diarrhea,? Schioler said. ?Bees don?t poop in the
hive unless they?re really sick. I noticed brown spots on the hive and knew
something was wrong.?
After two treatments and an attempt to revive the hive by moving a bottom
screen board from one hive to the top of the struggling hive to use the residual
warmth, Schioler was forced to write off the colony.
?When I first opened up the hive, the bottom brood box was just filled with
dead bees,? he said.
Nosema has a name and a face. What happened next was less discriminating and
really stung. Following the recommendation of a colleague from the coast,
Schioler tried using an antibiotic on two hives as a precautionary measure.
?It didn?t work,? he said. ?They died.?
Both hives had never been used for pollination and were thus never exposed
to diseases.
?I just used them for honey,? the pollinator said. ?I thought the second
hive three weeks ago was gangbusters and then Thursday I look in there and all
the frames are empty.?
The bees he found were black and wet-looking, consistent with Colony
Collapse Disorder. At the bottom of the box, the queen was half the normal size and
only she and young, attendant bees remained. The hive was full of honey and
nectar, leaving Schioler puzzled, as other bees will generally swoop in and loot
if the opportunity is presented.
?They stayed the hell away from it,? he said. ?There were no older bees.?
Schioler divides his time between producing honey and commercial
pollination. At last Sunday?s Ballard Farmer?s Market he met a beekeeper who lost 20 of
his 22 hives. Another beekeeper in Tenino had it much worse, losing all 350 of
his hives.
Whether a person shares Schioler?s passion for bees is irrelevant in the
face of what he claims is a potentially catastrophic harbinger. From 1971 to 2006
approximately half of the U.S. honey bee colonies have vanished. Theories for
the cumulative loss range from environmental change-related stresses, to
malnutrition, to mites, to pesticides, to electromagnetic radiation, such as
cellular phone signals. More recently the rate of attrition was alleged to have
reached new proportions, according to Wikipedia, and the term Colony Collapse
Disorder was proposed to describe the sudden rash of disappearances.
?Einstein predicted that if bees were to die, humans would starve within
four years,? Schioler said. ?If this continues, we could starve in two
generations. People need to decide if they want a beautiful lawn or if they want to eat
in the future.?
In 1962, Rachel Carson wrote the book Silent Spring, which has been credited
with launching the environmentalism movement in the West. The book claimed
detrimental effects of pesticides on the environment and ultimately facilitated
the ban of the pesticide DDT in 1972 in the U.S.
?We?ve known the problems were there for a long time,? Schioler said.
The decline of bee populations in the U.S. prompted the importation of 1.5
million hives from Australia.
?That?s how short we are,? the beekeeper said. ?And they fear that will
bring problems of its own in the form of small hive beetles.?
With a relatively modest 39 hives in Greenbank and 10 more in California,
Schioler makes the most of his resources. His colleague and mentor Jim Malsch of
Arlington manages 700 hives. The seasoned bee veteran has not been affected
by CCD and is loath to predict doom and gloom.
?If you?re a beekeeper, the healthier you can keep your bees the better they
?re going to be for pollinating and over-wintering,? Malsch said. ?If you
can keep good, healthy bees, they?ll survive.?
The longtime beekeeper and pollinator has had his battles with mites. In
1993, he was left with just 160 of the 400 hives he sent to California for almond
pollination. Varroa mites had irreparably weakened the hives. In the end, he
said, the onus falls on the beekeeper.
?You have to be diligent about keeping on top of it,? Malsch said, adding
that some attrition is to be expected. ?If you lose 20 percent of your bees in
the winter, you can live with that.?
Malsch said mites have been the biggest problem since they appeared in the
late 1980s.
?I kept bees before we had mites here and it was a lot easier to keep them
and over-winter them,? he said. ?You have to keep the mite population down. You
?re never going to totally get rid of them.?
Waxing theoretical, Malsch postulated that Colony Collapse Disorder is a
result of bees becoming weakened by mites and rendering them helpless to mites
and parasites.
?I believe the viruses have always been here, but when the viruses come
along with the mites, the bees get in a weakened condition through stress or mites
or whatever and they?re more susceptible,? he said.
Whidbey Island is a microcosmic example of what is taking place nationwide.
Ohio alone has lost nearly 90 percent of its hives.
?There?s virtually no bees left on the island,? he said, imploring people
to stop using pesticides and to cease cutting down blackberry bushes and
wildflowers. ?Honey is emergency food. Nectar and pollen are what bees need.?
Bees are often mistaken for oft-maligned hornets, which are carnivorous.
Schioler said the role bees play in helping the food chain from humans on down is
crucial to survival.
?People have to change their attitude toward bees rather than arbitrarily
kill everything that they think looks like a bee,? he said. ?You have to
physically crush a bee to get stung.?
Schioler, because he pollinates, is able to produce 14 different kinds of
honey. His breed, however, is a rare one.
?Twenty years ago there were about 3,000 pollinators in the U.S.,? he said.
?Today there are less than 400. We probably have four commercial pollinators
in a 100-mile radius who can do over 50 hives and maybe five to ten who can do
50 to 100. There is not enough pollination on Whidbey.?
Schioler is looking to do his part to help in the pollination process. He is
always looking to park hives on property with large amounts of blackberry
bushes and other types of flora.
?If people are willing to let me put hives there, they?ll get some very
good honey,? he said.
Schioler can be reached at 425-299-1135.

UCSF scientist tracks down suspect in honeybee deaths
Sabin Russell, Chronicle Staff Writer
Thursday, April 26, 2007
About one-quarter of the United States' 2.4 million
honey...
A UCSF researcher who found the SARS virus in 2003 and later won a MacArthur
Foundation "genius grant" for his work thinks he has discovered a culprit in
the alarming deaths of honeybees across the United States.
Tests of genetic material taken from a "collapsed colony" in Merced County
point to a once-rare microbe that previously affected only Asian bees but
might have evolved into a strain lethal to those in Europe and the United
States, biochemist Joe DeRisi said Wednesday.
DeRisi said tests conducted on material from dead bees at his Mission Bay
lab found genes of the single-celled, spore-producing parasite Nosema
ceranae, which researchers in Spain have recently shown is capable of wiping
out a beehive.
"It is wise to strike a conservative note, because this is early data, but
it is interesting,'' he said.
Government scientists who have been tracking the phenomenon they call Colony
Collapse Disorder were skeptical, however, saying the parasite had been an
early suspect in the bee die-off but that they had concluded it probably was
not responsible.
With a mounting sense of urgency, agricultural scientists are trying to find
out just what has caused the disappearance of as much as a quarter of the
nation's 2.4 million honeybee colonies since November, when the die-off was
first observed by a Pennsylvania beekeeper.
It's not just bad news for beekeepers and honey lovers. Growers of fruits,
nuts and many vegetables rely on honeybees to pollinate their crops, which
contribute $15 billion to the nation's agricultural output, according to a
Cornell University study.
DeRisi is a specialist in the rapid identification of killer germs. In March
2003, he played a key role in helping the federal Centers for Disease
Control and Prevention identify the cause of SARS, or severe acute
respiratory syndrome, the viral illness that claimed 774 lives and wreaked
havoc for a time on the Asian economy.
Using a laboratory tool called a microarray -- which can instantly match a
sample to gene sequences from more than a thousand viruses -- he found that
SARS was caused by a previously unknown variant of coronavirus, a microbial
family responsible for a variety of ailments including the common cold.
The following year, he was awarded a $500,000 MacArthur Fellowship, the
prize given by the foundation to individuals who have no idea they were
nominated until they win. The awards are popularly known as genius grants.
In researching the bee die-offs, DeRisi's team evaluated samples of
potential bee pathogens supplied by the Army's biodefense laboratory, the
Edgewood Chemical Biological Center at the Aberdeen Proving Ground in
Maryland.
Scientists there had developed a technique to concentrate possible pathogens
into a sample that could be run through a rapid genetic screen test such as
DeRisi's. Samples taken from dead bees in a collapsed colony from Le Grand
(Merced County) were shipped via overnight mail to DeRisi's San Francisco
lab last week.
DeRisi used a technique that allows rapid reading of the genetic code of the
suspect bug. It is the same approach, known as "shotgun sequencing," that
has been used to read the genomes, or the genetic code, of creatures ranging
from bacteria to human beings.
The strips of genetic code are then matched to computerized libraries of
known genes from thousands of germs. It was this test that pinpointed Nosema
ceranae.
"The bees must have been loaded with this stuff,'' said DeRisi, who
collaborated in the experiment with Dr. Donald Ganem of the UCSF Department
of Microbiology and Immunology.
Fueling the UCSF scientists' interest in the parasite is a recent paper,
published by the Journal of Invertebrate Pathology in January, in which a
team of Spanish researchers infected hives of European honeybees with Nosema
ceranae. Within eight days, the colonies were wiped out.
The federal government's leading honeybee scientists, however, are not ready
to conclude that DeRisi has found anything significant. Jeffery Pettis,
research leader for the U.S. Agriculture Department's Bee Research
Laboratory in Beltsville, Md., said reports suggesting that this parasite
has recently appeared in the United States are simply wrong. "There are
historical samples from the mid-1990s,'' he said.
Before then, the parasite was seldom seen outside Asia, where it favored a
species of honeybee found only there. It did not cause colony collapse in
Asia.
Now, Pettis said, tests have shown that Nosema ceranae has displaced a
related strain that had been the dominant form of the parasite in the United
States, Pettis said. However, large quantities of the microbe have been
found in bee colonies that are healthy, as well as in those that have
collapsed, he said.
Pettis said the parasite could simply be taking advantage of a newly
developed weakness in the insects' immune systems. "Mostly we think of
Nosema as a stress disorder of honeybees,'' he said.
It is possible that a more virulent strain of Nosema ceranae has evolved in
the United States, but Pettis doubts it. "We can't rule it out completely,''
he said.
Evan Skowronski, senior team leader for biosciences at the Army lab and a
friend of DeRisi's, said that because the stake are high, every important
lead in the search for the cause of the honeybee deaths needs to be pursued.
"We're not ready to say this is it, but it is a pathogen of interest,'' he
said.
Skowronski said there is no reason to think that the cause of Colony
Collapse Disorder is "anything other than Mother Nature.'' However, he said
that any natural threat to honeybees has major implications for the United
States. "This needs a high level of attention,'' he said.
DeRisi agreed that more tests will be needed to prove or disprove the
parasite's role in the disappearance of the bees.
"In our results, the control bees did not have it, and the sick ones were
loaded with the stuff,'' he said. "It is going to take a lot of time to
figure out.''

'Killer bees' seem resistant to disorder
By Dan Sorenson
arizona daily star
Tucson, Arizona | Published: 03.30.2007
Although experts are stumped about what's causing the colony-collapse
disorder die-off in U.S. commercial beehives, there is some speculation that
Arizona's famed Africanized ?? or "killer bee" ?? wild-bee population is somehow
immune.
Dee Lusby's bees are doing fine. Actually, they're doing better than that,
says the owner of Lusby Apiaries & Arizona Rangeland Honey of Arivaca.
Lusby has 900 hives of "free range" organic bees spread out over ranches from
Benson to Sasabe.
"I've only lost one or two, maybe three (hives) out of every 30 or 40 hives,"
said Lusby.
She's not surprised by her good fortune or the modern commercial beekeepers'
hive-mortality rates.
Lusby has a hunch the disorder is the result of a number of factors,
including the use of pesticides, bee-growth formulas, artificial food supplements,
breeding for size, inbreeding ?? all or some of which may make them susceptible
to mites, viruses and fungi ?? and maybe even some strange side effects from
feeding on genetically modified crops.
Breeding for size is a major factor, Lusby believes. She says the commercial
honeybees are now too large to feed on some of the very plants that
historically may have given them immunity to diseases and parasites. They're simply too
big to get into those plant's flowers, she says.
And the man who takes the bees out of Bisbee, Reed "The Killer Bee Guy"
Booth, says he's not surprised Africanized bees are thriving.
Booth started out with beekeeping to make retail honey and honey mustard, and
branched out to do bee removals after the Africanized bees invaded Arizona in
the early 1990s. He says he gets one to five eradication calls a day from
around Cochise County during warm weather.
"It's going to be a banner year for bees," he says.
"The Africanized bees are somewhat more resistant" than the European
honeybees, he says of the aggressive, slightly smaller wild bees that produce bumper
crops of honey and bad press. "But they're somewhat resistant to anything,
probably including nuclear war."
Booth says he switched from European bees to wild Africanized bees not long
after they spread through Arizona.
"I used to have two sets of hives," says Booth. "But I got tired of going
down and either finding my European bees Africanized or dead. I gave up, so,
Killer Bee Honey."
But Gloria DeGrandi-Hoffman, research leader of the USDA's Carl Hayden Bee
Research Center in Tucson, is not so quick to crown the wildly enthusiastic
Africanized honeybees as superior.
"We don't push the African populations like we do Europeans,"
DeGrandi-Hoffman said of the carefully genetically controlled honeybees used by commercial
beekeepers for field work.
"We're putting them on trucks and taking them halfway across the country.
We're stressing them in almost a feedlot situation, feeding them protein
supplements. We're stressing them pretty good. And that doesn't happen with Africans."

See any bumblebee nests? Report them to Oregon State
A research program on pollination biology led by Sujaya Rao, in the Crop and
Soils Department at Oregon State University, is looking for nests of
bumblebees in the mid-Willamette Valley. The program is looking for ways of increasing
this important pollinator group in the area.
If you have noticed large bumblebees entering and leaving their nests,
located either in holes in the ground or in bird nests, you are asked to call Dr.
Rao at 737-9038 or contact her via e-mail at sujaya at oregonstate.edu. She or one
of her cooperators will come out and pick them up.
?Please do not destroy them by spraying,? the researcher asked. The nest
entrances of bumblebees are usually in old mole, mouse or vole holes and
occasionally will be found in above-ground locations such as bird nests.

WELCOME
The _Wildlife Habitat Council_ (http://www.wildlifehc.org/) ?s (WHC)
Restoring Greenspace 2007 conference is quickly approaching. This series of
conferences is designed to help participants strategize the necessary problem-solving
steps in making ecological enhancements a reality. The conference will focus on
the incorporation of ecological reuse practices in site restoration in U.S.
EPA Region 4.
For the first time, _Continuing Education Units_
(http://www.wildlifehc.org/events/restoringgreenspace_agenda.cfm) (CEU) will be offered for those
attending the conference. CEUs are a nationally recognized method of quantifying time
spent during professional development and training activities and can be
submitted as proof of continuing education to state licensing boards and
employers. They are important for documenting career enhancing activities, and earned
units will be based on actual instruction time at the event. Ten (10) hours of
instruction equal one (1) CEU. Both workshops and the conference will be
offered for continuing education credits through the University of Georgia Fanning
Institute with no charge for this service.
_Jimmy Palmer_
(http://www.wildlifehc.org/events/restoringgreenspace_news.cfm) , Regional Administrator of EPA?s southeast region will provide opening
remarks at the conference. ?As we encourage communities to achieve their economic
goals through responsible development, land revitalization and restoration of
contaminated sites are vital components of success,? said Palmer. ?Through
partnerships with state and local governments, other federal agencies,
corporations, non-profit organizations, and academia, revitalization and restoration
efforts will allow us to pass on to the next generation a healthier, safer, more
prosperous world.?
NEW PRE-CONFERENCE WORKSHOPS
WHC will offer _two pre-conference workshops_
(http://www.wildlifehc.org/events/restoringgreenspace_agenda.cfm) with leading experts on Monday, May 21,
2007. These workshops will set the stage for the main goals of the conference
and familiarize participants with unique and improved techniques of ecological
enhancements.
Throughout the following two days of Restoring Greenspace 2007, _breakout
sessions_ (http://www.wildlifehc.org/events/restoringgreenspace_agenda.cfm) will
focus on wetlands, managing liability and community engagement to name just a
few key topics. Remediation of contaminated wetlands poses additional
challenges to environmental managers, regulators and conservation organizations. Our
nation?s coastal and freshwater wetlands are critical for both biodiversity
and local economies thereby the stakes are high for successful remediation.
Two breakout sessions will focus on varying _wetlands issues_
(http://www.wildlifehc.org/events/restoringgreenspace_agenda.cfm) . North American Wetland
Engineering (NAWE) will share the successes and challenges of a passive
treatment system at an NPL site in New York. NAWE is the leader in the decentralized
water and wastewater industry, providing innovative and ecological solutions
for industrial, residential and municipal clients. Ducks Unlimited, Inc. will
discuss one of the largest estuarine habitat restoration projects currently
underway in the United States. Also hear from AMEC Earth and Environmental,

Subject: [Pollinator] Tuscaloosa News.com -Whit Gibbons: Commentary on
Pollinator Week
Message-ID:
Published Sunday, April 29, 2007
WHIT GIBBONS: Pollinators essential to human food sources
Last fall, Sen. Saxby Chambliss of Georgia submitted U.S. Senate Resolution
580, which recognizes ?the importance of pollinators to ecosystem health and
agriculture in the United States and the value of partnership efforts to
increase awareness about pollinators and support for protecting and sustaining
pollinators by designating June 24 through June 30, as National Pollinator Week."
The Senate had the wisdom to approve the resolution.
For Congress to spend time on such an issue may, at first, seem frivolous.
But consider this: if pollination were to diminish or cease completely, the
results would be disastrous for everyone who consumes food. Pollinators are an
essential element of the environmental framework of which we are a part and upon
which we all depend. For our national representatives to acknowledge this
reality is hardly frivolous.
The Senate resolution refers to a Web site (www.pollinator.org) as a source
for pollinator information. The Pollinator Partnership asserts that ?
pollinators are essential to life." For life as we know it, this is absolutely true.
Pollination of native plants and agricultural crops is one of those critical
biological services that we simply take for granted because it is taken care of at
no cost to us. More than three-fourths of the world?s crop plants depend on
pollination by flying animals to produce seeds or fruit. According to the
resolution, ?pollinators help to produce an estimated 1 out of every 3 bites of
food consumed in the United States."
Who are these important creatures that assume the key role of moving pollen
from one flower to another? In addition to the bee, wasp and butterfly
pollinators we are accustomed to, beetles, flies and mosquitoes are also important.
Although we may think of hummingbirds as backyard visitors that drink nectar
from hanging containers, in fact, they are also significant pollinators. Some
flowers in the western United States and American tropics are dependent on
hummingbird pollinators for their propagation; they are not found in regions where
hummingbirds are absent. And in the Sonoran Desert, Saguaro cacti are
pollinated by bats at night.
In addition to the vital role pollination plays in producing the vegetative
landscapes we are familiar with and providing most of the food we eat, economic
considerations are also substantial. For example, according to the
resolution, ?animal pollinators generate significant income for agricultural producers,
with domestic honeybees alone pollinating" more than $14 billion worth of
crops each year in the United States. The resolution also considers what would
happen if the size and general health of populations of pollinators were to
decline on a national or international scale. It should be viewed as ?a significant
threat to global food webs, the integrity of biodiversity and human health."
Clearly, it is in the best interest of all of us for healthy populations of
pollinators to remain with us.
One ingredient is missing from the Senate resolution about the importance of
pollinators and their healthy persistence in the ecosystem: What should we do,
or not do, to ensure that pollinating insects and flying vertebrates remain
with us? That information is available on the pollinator Web site.
?Due to biodiversity threats such as land development, pollution and
pesticide poisoning, we are losing pollinators around the world at an alarming rate."
So we need to limit development, curb pollution and curtail pesticide use.
Ironically, the very pesticides that are viewed by some as essential to our
agricultural economy are also considered to be the culprit in the decline of some
of the insects necessary for pollination.
The pollinator Web site, sponsored by the North American Pollinator
Protection Campaign and the Coevolution Institute, is a valuable environmental
resource. It answers some frequently asked questions at the ?What Is Pollination?"
link, helps develop public awareness of just how fragile our connections are to
the world?s ecosystems and emphasizes the importance of ecologists who are
working to understand pollination systems.
The underlying message of the Web site and the Senate resolution is clear. If
even small, flying insects are essential for us to live on earth, we should
value and preserve every part of our environment.

The case of the missing bees

in the area. Many of his hives are coming up empty, below left. Edelensays

April 29, 2007
The nation?s main pollinators are rapidly disappearing, and no one knows for
sure why As spring unfurls, honeybees are expected to be rousing themselves
from their winter dormancy and going about their busy work of collecting flower
nectar to make into honey, pollinating crops in the process. But large numbers
of bees simply aren't showing up for work this year.
In early visits to hives, beekeepers in 27 states have reported empty boxes
without so much as a bee body left to run tests on. As of this writing, New
Mexico was not on the map of states considered affected by the problem. But a
report from a beekeeper at a Southern New Mexico bee yard indicates maybe it
should be.
The problem of AWOL honeybees -- which has been dubbed Colony Collapse
Disorder -- has prompted a congressional hearing and concern among beekeepers and
produce growers about the ramifications of massive losses of the nation's main
pollinator of crops.
Kevin Hackett, a program leader with the United States Department of
Agriculture's Agricultural Research Service, said the agency plans to spend $9 million
studying bees this year, half of it on Colony Collapse Disorder.
Hard data about the extent of the problem is spotty. But, according to
researchers at the USDA, as many as 25 percent of the country's 2.5 million bee
colonies have disappeared or been killed off by the phenomenon.
As scientists and others scramble to determine the cause of the problem,
speculation -- some of it wild -- abounds. The most recent theory, according a
story Thursday in the Los Angeles Times, quoted a "highly preliminary"
University of California, San Francisco study that links the disorder to a
single-celled fungal parasite called Nosema ceranae.
Nosema and other viruses have been found in some of the bee bodies that were
left behind in abandoned colonies across the country. Hackett said the
prevalence of viruses might indicate that the bees are suffering from some sort of
immune-system suppression.
Some apiary-industry insiders speculate that bees could be stressed to their
breaking point by being trucked about in big rigs and fed sugar water. "They
are locked up in hives moving thousands of miles across the country. They
can't take cleansing flights. You interrupt the sociality of the colony." Hackett
said. "It's a combination of factors, a 'perfect storm' kind of situation."
But, he pointed out, some nonmigratory beekeepers are also experiencing the
disorder.
Others blame overuse and lax regulation of pesticides. Some suspect a virus
or bacteria carried by varroa mites, which have been causing declines in bee
populations for more than a decade. Cell-phones signals also are being blamed
for confusing bees to the point that they can't find their way home. Others
claim the dwindling pollinator population is a sure sign of the apocalypse.
