Maternally-inherited bacteria can affect the fitness and population dynamics of their host insects; for solitary bees, such effects have the potential to influence bee efficacy as pollinators. We screened bee species for bacterial associates using 454-pyrosequencing (4 species) and diagnostic PCR (183 specimens across 29 species). The endosymbiont Wolbachia was abundant, infecting 18 species, including all specimens from the family Halictidae. Among commercially-supplied orchard bees (family Megachilidae), only 2/7 species were Wolbachia-infected, but one species showed variable infection among specimens. Two other maternally-inherited bacteria, Arsenophonus and Sodalis, were also detected, neither of which was fixed in infection frequency. Differential endosymbiont infection could potentially compromise fitness and reproductive compatibility among commercially redistributed pollinator populations.
母系遗传细菌会影响其宿主昆虫的适应性和种群动态；对于独居蜜蜂而言，此类影响有可能影响蜜蜂作为传粉者的功效。我们使用454焦磷酸测序法（对4个物种）和诊断性聚合酶链反应（对29个物种的183个标本）对蜜蜂物种的细菌共生体进行了筛选。内共生菌沃尔巴克氏体很常见，感染了18个物种，包括隧蜂科的所有标本。在商业供应的果园蜜蜂（切叶蜂科）中，只有2/7的物种感染了沃尔巴克氏体，但有一个物种的标本之间感染情况存在差异。还检测到另外两种母系遗传细菌，即共生菌属和 Sodalis，它们的感染频率均未固定。不同的内共生菌感染可能会损害商业再分配传粉者种群之间的适应性和生殖兼容性。
