Funds are requested to purchase a coupled gas chromatograph/mass spectrometer that will be used primarily in studies of the ecology, behavior and physiology of insects. Several projects are proposed. The instrument will be used to identify pheromones and other behaviorally active compounds from bark beetles that inhabit pine trees. Another project will study the biosynthetic pathway of phenromones in fruit flies and also cuticular lipids that are important water proofing agents in mole crickets. Another study will use the instrument to study allochemicals and their metabolites that are responsible for enzyme induction in insects. Cardiac glycosides and pyrrolizidine alkaloids used as defensive compounds by butterflies will be identified with the instrument. Finally, the insect hormones involved in host parasite interactions will also be determined.

需要资金购买一台气相色谱仪/质谱仪，主要用于研究昆虫的生态学、行为和生理学。提出了几个项目。该仪器将用于识别栖息在松树上的树皮甲虫的信息素和其他行为活性化合物。另一个项目将研究果蝇体内菲咯酮的生物合成途径，以及作为鼹鼠蟋蟀重要防水剂的角质层脂类。另一项研究将使用该仪器研究导致昆虫酶诱导的同种异体化学物质及其代谢物。作为蝴蝶防御性化合物的心脏糖苷和吡咯里西丁生物碱将通过该仪器进行鉴定。最后，还将确定与寄主寄生虫相互作用有关的昆虫激素。
