寄主-共生体的动态已知会影响寄主的表型，但它们在社会行为中的作用还有待研究。不同蜂种的生活史差异可能会影响肠道共生菌的群落组成，进而影响蜂种的表型。我们通过描述不同蜂种：蜂王、雄蜂和两种工蜂、护士和采食者的后肠微生物群落，研究了寄主-共生动态与社会行为之间的关系。尽管蜂巢环境和鸟儿间的口对口食物转移是共享的，但我们检测到蚁后、工蚁和雄蚁的肠道微生物群是分离的。护士和觅食者的肠道微生物群与以前描述的蜜蜂工蜂微生物群相似，而且彼此相似，尽管在饮食、活动和对外部环境的暴露方面存在差异。皇后微生物群丰富了细菌，这些细菌可能会加强从食物到鸡蛋生产的能量代谢转换。我们认为，这两种类型的工作者具有最高的细菌操作分类单位(OTU)多样性，是维持菌落微生物组的核心。觅食者可能会将新的细菌菌株从环境中引入群体，并将它们转移到护士手中，护士对其进行过滤，并将其分配给群体的其他成员。我们的结果支持这样的观点，即宿主-共生体动力学影响微生物群的组成，并反过来影响宿主的社会行为。
Host-symbiont dynamics are known to influence host phenotype, but their role in social behavior has yet to be investigated. Variation in life history across honey bee (Apis mellifera) castes may influence community composition of gut symbionts, which may in turn influence caste phenotypes. We investigated the relationship between host-symbiont dynamics and social behavior by characterizing the hindgut microbiome among distinct honey bee castes: queens, males and two types of workers, nurses and foragers. Despite a shared hive environment and mouth-to-mouth food transfer among nestmates, we detected separation among gut microbiomes of queens, workers, and males. Gut microbiomes of nurses and foragers were similar to previously characterized honey bee worker microbiomes and to each other, despite differences in diet, activity, and exposure to the external environment. Queen microbiomes were enriched for bacteria that may enhance metabolic conversion of energy from food to egg production. We propose that the two types of workers, which have the highest diversity of operational taxonomic units (OTUs) of bacteria, are central to the maintenance of the colony microbiome. Foragers may introduce new strains of bacteria to the colony from the environment and transfer them to nurses, who filter and distribute them to the rest of the colony. Our results support the idea that host-symbiont dynamics influence microbiome composition and, reciprocally, host social behavior.
