Shultz 9902198Plant defenses induced by herbivory are better understood than changes in host plant physiology which benefit insects. This study will examine the mechanistic bases of the ability of insects to manipulate plant physiology to their own advantage. It will use the witch hazel cone gall aphid to test hypotheses regarding the aphid's ability to alter source-sink relationships and photoassimilate allocation, the mechanism by which these alterations are effected, the adaptive value to the insect and the negative effects on hostplant biomass allocation and fitness. This area of gall biology is not well studied and this proposal has the potential to lead to valuable insights to gall forming insects and plant evolutionary biology.

Shultz 9902198比寄主植物的有益于昆虫的生理变化更好地理解了草食诱导的植物防御。这项研究将考察昆虫为自己的利益操纵植物生理的能力的机制基础。它将使用金缕梅球果五倍子来测试有关蚜虫改变源-库关系和光同化物分配的能力、影响这些改变的机制、对昆虫的适应价值以及对寄主植物生物量分配和适合度的负面影响的假说。胆汁生物学的这一领域还没有得到很好的研究，这一提议有可能为形成胆汁的昆虫和植物进化生物学带来有价值的见解。
