<div><font face="garamond, serif" size="4"><br></font></div><p class="last" style="margin:0pt 0pt 1em;line-height:21px;background-color:rgb(255,255,255)"><font face="garamond, serif" size="4">Four North American bumble bee species in the subgenus <i>Bombus</i> sensu stricto, including <i>Bombus occidentalis</i> (Hymenoptera: Apidae), are experiencing dramatic declines in population abundance, geographic range and genetic diversity. The prevailing hypothesis concerning their decline is the transmission of the intracellular fungal pathogen. <i>Nosema bombi</i> (Microsporida), and other pathogen species from commercially reared bumble bees to wild populations. While <i>N. bombi</i> incidence has been investigated in the contiguous U.S.A. and Canada, virtually nothing is known about the status of Alaskan bumble bees. This study presents the distribution and relative abundance of <i>B. occidentalis</i>and <i>B. moderatus</i>, two co-occurring species in the subgenus <i>Bombus</i> sensu stricto, in Alaska and the prevalence of <i>N. bombi</i> detected in these species. <i>Bombus occidentalis</i> and <i>B. moderatus</i> accounted for 28% and 4% of the 942 bumble bees surveyed, respectively. <i>Bombus occidentalis</i> was the most abundant species collected in the survey and prevalence of <i>N. bombi</i> infections (44% infected) was also highest in this species. The proportion of infected <i>B. moderatus</i> did not differ significantly from other co-occurring bumble bees. Despite the presence of <i>N</i>. <i>bombi</i> infections, both <i>Bombus</i> s. str. species were commonly detected in Alaska with our survey method. Alaskan bumble bee populations may thus provide important insights on the role of pathogens, particularly <i>N. bombi</i>, in bumble bee decline in the contiguous U.S.A.</font></p>
