9302757 Starmer This project will investigate the genetic basis of female egg laying behavior in conjunction with the performance of her offspring in a well studied species of Drosophila (D. buzzatii). Females of this species are known to display different preferences for laying their eggs on different microorganisms (yeasts) in the laboratory and in the field. These preferences are at least partly under genetic influence. Understanding the benefits of the mother's preferences to the offspring could explain several important aspects of evolutionary ecology such as 1) the maintenance of genetic diversity, 2) the evolution of host-specialization and 3) the origin of species.%%% Experiments will compare female egg laying behavior to the performance of her larvae with attention to both environmental and genetic aspects. Four distinct strains of D. buzzatii representing independent genetically determined egg laying responses to yeast species that grow in the natural habitat will be used. The experiments are designed to approximate the biological situation as we know it from extensive field studies. Interpretations about genetically based behavior should be useful to basic biology, evolutionary ecology, applied aspects of conservation biology and biological control of insect pests. ***

小行星9302757 本计画将研究果蝇雌性产卵行为的遗传基础，并结合其后代的表现。buzzatii）。 已知该物种的雌性在实验室和野外对不同的微生物（酵母）产卵表现出不同的偏好。 这些偏好至少部分受到基因的影响。 了解母亲的偏好对后代的好处可以解释进化生态学的几个重要方面，例如1）遗传多样性的维持，2）宿主专业化的进化和3）物种的起源。 实验将比较雌性产卵行为与其幼虫的表现，同时关注环境和遗传方面。 4个不同的D.将使用代表对在自然栖息地中生长的酵母物种的独立遗传决定的产卵反应的buzzatii。 实验的目的是近似的生物情况，因为我们知道它从广泛的实地研究。 对遗传行为的解释对基础生物学、进化生态学、保护生物学和害虫生物防治的应用方面都是有用的。 ***
