Spillover of chalkbrood fungi to native solitary bee species from non-native congeners
<p>Introduced, managed bees such as mason bees (genus <em>Osmia</em>) can confer significant pollination benefits to agricultural systems, but a risk of introducing non-native species into new ecosystems is the co-introduction of pathogens along with them. Pathogen spillover to wild, native bees may then drive native bee species declines.</p> <p>This study examined prevalence of the chalkbrood-causing fungal genus <em>Ascosphaera</em> in the nests of both non-native and native mason bee species. We conducted large-scale trap-nesting and pan-trapping efforts across the Mid-Atlantic United States with community scientists. Using molecular methods, nests were screened for all known <em>Ascosphaera</em> species in which genetic sequences have been published. After finding <em>Ascosphaera</em> species first described in Asia, we compared their local prevalence with the local abundance of mason bees from Asia. Lastly, we compared the prevalence of co-introduced Ascosphaera species across sites with a variety of landcover profiles.</p> <p>Results indicate species originally described in Japan, <em>Ascosphaera naganensis</em> and <em>Ascosphaera fusiformis</em>, are now present in native Virginia mason bees, <em>Osmia lignaria</em> and <em>Osmia georgica</em>, with high prevalence of <em>A. naganensis</em> found in <em>O. georgica</em>.</p> <p>We also found that the declining native mason bee <em>O. georgica</em> experienced higher prevalence of non-native <em>Ascosphaera</em> spp. at sites with larger numbers of non-native <em>O. cornifrons</em> and <em>O. taurus</em>, perhaps indicating greater likelihood of spillover of these <em>Ascosphaera</em> species with greater sources of transmission. Lastly, when the proportion of agricultural landcover surrounding bee nests was high, there was significantly greater prevalence of non-native <em>Ascosphaera</em> in <em>O. georgica</em> compared to more natural landcover types.</p> <p>Synthesis and applications. Through community science programming, we documented species of Japanese chalkbrood fungi inside native mason bee nests in North America. Native mason bees encounter non-native fungi more frequently with increasing abundance of non-native mason bees. Agricultural landscapes may exacerbate spillover of non-native fungi for native mason bees. The use of non-native bee species in agriculture should involve monitoring native bees for pathogens in the surrounding area for detection of spillover and species declines.</p>
