97-28608 Genetic, Developmental and Environmental Determinants of Honey Bee Foraging R. E. Page, Jr. Non-Technical Summary Honeybee colonies are normally composed of a queen and thousands of non-reproductive workers. The workers demonstrate a division of labor for behavioral tasks resulting in the survival, maintenance, and reproduction of the colony. One of the most interesting examples is the division of labor between workers inside the nest raising brood, constructing wax comb, processing honey, etc. and those that forage outside the nest. This division of tasks is often related to a worker's age. Some foragers specialize further in collecting nectar and others in collecting only pollen. Honeybee colonies must respond to changing conditions in the environment, such as the availability of food, and they must respond to changes in colony needs, such as the amount of pollen protein needed to feed a growing colony. Genetic make up is also important. Bees with some genetic constitutions are more likely to forage for pollen under a specific set of environmental conditions than are individuals of a different genotype. Building on previous research, this project will employ molecular genetic methodology to examine the influence of identified genes on foraging specialization, and to comprehensively examine how the influences of these genes interact with developmental (age) effects and environmental conditions.

97-28608蜜蜂觅食的遗传、发育和环境决定因素E.小佩奇 非技术性总结 蜂群通常由一个蜂王和成千上万的非繁殖性工蜂组成。 工蜂表现出行为任务的劳动分工，从而导致殖民地的生存、维护和繁殖。 最有趣的例子之一是巢内工蚁的劳动分工，它们负责养育幼仔、建造蜡巢、加工蜂蜜等，而那些在巢外觅食的工蚁则负责觅食。 这种分工往往与工人的年龄有关。 有些觅食蜂专门收集花蜜，有些则只收集花粉。 蜂群必须对环境中不断变化的条件做出反应，例如食物的可用性，并且它们必须对蜂群需求的变化做出反应，例如为成长中的蜂群提供食物所需的花粉蛋白量。 基因组成也很重要。 在特定的环境条件下，具有某些遗传结构的蜜蜂比不同基因型的个体更有可能寻找花粉。 本项目将在以往研究的基础上，采用分子遗传学方法研究已鉴定基因对觅食专化的影响，并全面研究这些基因的影响如何与发育（年龄）效应和环境条件相互作用。
