昆虫社会的群体水平表型是由大量个体之间的相互作用产生的，这些个体在形态、生理和行为上可能存在很大差异。形成这一复杂集成系统的直接和最终机制尚不完全清楚，了解社会生活策略的演变是系统生物学的一个主要课题。在独居昆虫中，行为、感觉调节和生殖生理学是相互联系的。这些关联部分受到组织生殖周期阶段顺序表达的多效性网络的控制。在这里，我们探讨类似的关联是否会在社会工作者种姓中产生不同的行为表型。我们记录了控制功能性不育工蜂（Apis mellifera）觅食行为的多效性遗传网络具有生殖成分。具有不同觅食策略的工蚁的行为、生理和感觉调节之间的关联表明，潜在的遗传结构是。旨在控制生殖周期。构成生殖策略调节“基本计划”的基因回路可能为社会生活提供强大的构建模块。我们认为，对这一地面规划的利用在社会性昆虫社会的进化中发挥着重要作用。
The colony-level phenotype of an insect society emerges from interactions between large numbers of individuals that may differ considerably in their morphology, physiology, and behavior. The proximate and ultimate mechanisms that allow this complex integrated system to form are not fully known, and understanding the evolution of social life strategies is a major topic in systems biology. In solitary insects, behavior, sensory tuning, and reproductive physiology are linked. These associations are controlled in part by pleiotropic networks that organize the sequential expression of phases in the reproductive cycle. Here we explore whether similar associations give rise to different behavioral phenotypes in a eusocial worker caste. We document that the pleiotropic genetic network that controls foraging behavior in functionally sterile honey bee workers (Apis mellifera) has a reproductive component. Associations between behavior, physiology, and sensory tuning in workers with different foraging strategies indicate that the underlying genetic architectures were. designed to control a reproductive cycle. Genetic circuits that make up the regulatory "ground plan" of a reproductive strategy may provide powerful building blocks for social life. We suggest that exploitation of this ground plan plays a fundamental role in the evolution of social insect societies.
