与细菌的特殊关系通常允许动物通过提供一套新的代谢能力来利用新的饮食。蜜蜂是一个单系类群，从它们的黄蜂祖先的肉食性饮食过渡到完全的草食性饮食。最近的非培养研究表明，一组独特的细菌物种栖息在蜜蜂的肠道，意大利蜜蜂。在这里，我们调查了不同蜜蜂和黄蜂物种的肠道微生物，以测试这些细菌的获得是否与蜜蜂向草食性的过渡有关。我们发现，大多数蜜蜂物种缺乏与A. mellifera，拒绝假设，这种饮食过渡是共生依赖。独居蜜蜂物种中最常见的细菌是广泛分布的伯克霍尔德氏菌系统型和普遍存在的昆虫伴生菌沃尔巴克氏菌。相比之下，一些社会代表的corbiculate蜜蜂确实拥有独特的细菌的细菌类型。A.意大利蜜蜂的微生物群与以前的调查相同，在两种亚洲蜜蜂（Apis andreniformis和Apis dorsata）和几种熊蜂（Bombus）物种中鉴定了密切相关的细菌微生物群类型。潜在地，蜜蜂和熊蜂物种的社会性促进了共生体的传播，因此是维持更一致的肠道微生物群的关键。系统发育分析提供了一个更精确的分类位置的A。意大利蜜蜂共生体
Specialized relationships with bacteria often allow animals to exploit a new diet by providing a novel set of metabolic capabilities. Bees are a monophyletic group of Hymenoptera that transitioned to a completely herbivorous diet from the carnivorous diet of their wasp ancestors. Recent culture-independent studies suggest that a set of distinctive bacterial species inhabits the gut of the honey bee, Apis mellifera. Here we survey the gut microbiotae of diverse bee and wasp species to test whether acquisition of these bacteria was associated with the transition to herbivory in bees generally. We found that most bee species lack phylotypes that are the same or similar to those typical of A. mellifera, rejecting the hypothesis that this dietary transition was symbiont-dependent. The most common bacteria in solitary bee species are a widespread phylotype of Burkholderia and the pervasive insect associate, Wolbachia. In contrast, several social representatives of corbiculate bees do possess distinctive bacterial phylotypes. Samples of A. mellifera harboured the same microbiota as in previous surveys, and closely related bacterial phylotypes were identified in two Asian honey bees (Apis andreniformis and Apis dorsata) and several bumble bee (Bombus) species. Potentially, the sociality of Apis and Bombus species facilitates symbiont transmission and thus is key to the maintenance of a more consistent gut microbiota. Phylogenetic analyses provide a more refined taxonomic placement of the A. mellifera symbionts.
