<div><span style="font-size:12.800000190734863px">I think Kirk
Wattles is right to worry about this invasive bug. It
doesn't just feed on Ailanthus trees, it attacks some
commercial crops and some native trees, so efforts to
control it are going to be vigorous. The weakness it has is
its preference to feed on the Ailanthus tree in late summer
and lay eggs there in the fall. This is the reason
Pennsylvania is encouraging people in Lanternfly infested
zones to dose their Ailanthus trees with neonics
(imidacloprid, dinetofuran) before the bugs arrive.</span></div>

<div><span style="font-size:12.800000190734863px">Unfortunately,
there are reports from beekeepers that honeybees do like
Ailanthus flowers when in bloom. Bloom time is listed as
June-July. I think one constructive step would be for PA
agricultural authorities to amend their instructions to say
something like "if you use systemic pesticides on Ailanthus
trees, be sure to do so in early August, not before". This
will give the bees 10 months before they encounter the
pesticides in next year's flowers, which will reduce the
effective dose. It will also ensure the dose is higher when
the lanternflies arrive on the trees.</span></div>

</span></div>
<div><span style="font-size:12.800000190734863px">An alternative
for those willing to do a bit more work is to use something
like a horticultural oil spray on the trunks of Ailanthus
trees. As this requires contact, it won't kill everything,
but it should also get rid of egg clusters if they are
sprayed. The PA Agriculture folk recommend inspecting
Ailanthus trees on a property, cutting down the ones that
are less attractive to lantern flies, and just treating the
remaining ones. This should make whatever treatment is used
more effective.</span></div>

Friends,<br>
<br>
We're having a problem here in eastern Pennsylvania which
will likely have dire consequences for pollinator insects
(and others) in a wide section of the U.S., if not
nationally.<br>
<br>
I'm not an expert, but I know that 1 + 1 + 1 = 3.<br>
<br>
1 - The Spotted Lanternfly (Lycorma delicatula) is an
leaf-hopper-type insect that got started as an 'invasive' in
Berks County, Pennsylvania 4-5 years ago.<br>
<br>
1 - Official resources for containing and extirpating the
SLF are inadequate. The would-be quarantine zone has
expanded several times in the last two years, with nothing
to suggest that the invasion will be contained.? Wherever
the Ailanthus tree grows, they will multiply.<br>
<br>
1 - Neonicotinoid pesticides are the only "best" treatment,
and probably neonics (and other pesticides) will be very
heavily used by official agencies, farmers, and DIY
horticulturalists, and anyone who wants to protect their
trees. With knock-on effects on many other insects.<br>
<br>
I don't know how far knowledge of this problem has reached,
but I see little sign of concern or news coverage outside of
the locally affected areas.<br>
<br>
I won't elaborate on the details of the problem.? Again, I'm
not an expert.? I'm a beekeeper.? I heard through beekeeping
clubs in the affected area that local people were freaking
out, 4-6 weeks ago when the SLF graduated from the
instar/nymph stage and began dropping from the trees in
massive numbers.? When I investigated, I began to see how
neonics were being promoted by word of mouth and recognized
by the officials running the current efforts.? And how the
invasion is in the mid-phase of exponential growth.<br>
<br>
A lot of the relevant information and links are collected in
a facebook group 'Spotted Lanternfly' and on a facebook page
'Spotted Lanternfly Watch.' (Links to those may trigger spam
filters, so you can just look them up for yourselves.)? The
main agencies involved currently are the Pennsylvania
Department of Agriculture and Penn State University.<br>
<br>
It should be self-evident, to anyone who knows bugs reading
through that material (including the comments by
knowledgeable observers in the zone), how bad this problem
is likely to be.<br>
<br>
