Division of labor is a fundamental component of complex social systems, in groups as diverse as insects and mammals. In all social groups, division of labor involves specialization by individuals on certain tasks. However, for division of labor to function in a variable environment, it must allow for changes in task performance. In honey bees, Apis mellifera, task specialization depends on: (1) age polyethism, with individuals of different age groups performing different tasks within a colony, and (2) genetically-based individual preference for certain tasks. The long-term objective of this project is to determine the mechanisms for individual and societal task regulation in honey bees. More specifically, it will examine mechanisms for and constraints on individual flexibility in foraging behavior, and determine how individual variation in task performance is integrated into colony-level regulation of foraging. The project will use a variety of behavioral and genetic techniques, including use of instrumental insemination to construct honey bee colonies containing a variety of worker genotypes, and allozyme electrophoresis and DNA analyses (RAPD markers) to identify genetic subfamilies within colonies. Three principle questions will be addressed: (1) What are the relative contributions of individual flexibility and genotypic diversity to colony-level foraging plasticity?, (2) How do genetic and developmental constraints on individual behavioral flexibility constrain foraging behavior at the colony level?, and (3) How well do models of foraging flexibility developed using domesticated honey bee colonies predict the behavior of social groups under conditions of natural selection? This study will provide information crucial to understanding the evolution of division of labor in complex social systems, and mechanisms of behavioral flexibility in social insect colonies.

分工是复杂社会系统的基本组成部分， 在昆虫和哺乳动物的不同群体中。 在所有的社会群体中， 劳动分工涉及个人在某些方面的专业化。 任务 然而，为了使劳动分工在变量中起作用， 环境，它必须允许任务性能的变化。 蜂蜜中 蜜蜂（Apis mellifera）的任务特化取决于：（1）年龄多性， 不同年龄组的人执行不同的任务 在一个殖民地内，和（2）基于遗传的个人偏好， 某些任务。 本项目的长期目标是确定 蜜蜂的个体和社会任务调节机制。 更具体地说，它将审查促进和保护人权的机制和制约因素， 个体觅食行为的灵活性，并确定个体 任务表现的变化被整合到群体水平的调节中 觅食。 该项目将使用各种行为和遗传技术， 包括使用仪器授精来构建蜜蜂 含有各种工蜂基因型和等位酶的菌落 电泳和DNA分析（RAPD标记），以确定遗传 殖民地内的亚家族。 三个主要问题将是 问题：（1）个人的相对贡献是什么？ 灵活性和基因型多样性对群体水平觅食可塑性的影响， (2)遗传和发育对个体行为的限制 在殖民地水平上限制觅食行为的灵活性，（3）如何 利用驯化蜂蜜开发的觅食灵活性模型做得很好 蜂群预测社会群体的行为， 自然选择？这项研究将提供至关重要的信息， 理解复杂社会分工的演变 系统和机制的行为灵活性在社会昆虫 殖民地
