大型社会性昆虫群体表现出显着的能力，识别群体成员通过殖民地特定的表皮信息素签名。以前的工作表明，在一些蚂蚁物种，殖民地特定的信息素配置文件是通过一种机制，涉及转移和均匀化的表皮碳氢化合物（CHCs）的成员之间的殖民地。然而，如何在其他社会性昆虫分支中产生群体特异性化学谱仍然是未知的。在这里，我们表明，在蜜蜂（意大利蜜蜂），殖民地特异性CHC配置文件完成其成熟觅食通过一系列刻板的年龄依赖性的定量和定性的化学转变，这是由环境敏感的内在生物合成途径驱动。因此，个体蜜蜂的CHC谱不太可能通过均质化和转移机制产生，而是与年龄相关的劳动分工相关联而成熟。此外，非巢友拒绝行为似乎是上下文限制进入觅食和警卫在蜂巢入口之间的行为互动。
Large social insect colonies exhibit a remarkable ability for recognizing group members via colony-specific cuticular pheromonal signatures. Previous work suggested that in some ant species, colony-specific pheromonal profiles are generated through a mechanism involving the transfer and homogenization of cuticular hydrocarbons (CHCs) across members of the colony. However, how colony-specific chemical profiles are generated in other social insect clades remains mostly unknown. Here we show that in the honey bee (Apis mellifera), the colony-specific CHC profile completes its maturation in foragers via a sequence of stereotypic age-dependent quantitative and qualitative chemical transitions, which are driven by environmentally-sensitive intrinsic biosynthetic pathways. Therefore, the CHC profiles of individual honey bees are not likely produced through homogenization and transfer mechanisms, but instead mature in association with age-dependent division of labor. Furthermore, non-nestmate rejection behaviors seem to be contextually restricted to behavioral interactions between entering foragers and guards at the hive entrance.
