CHEMISTRY OF ARTHROPOD SECRETIONS

昆虫和其他节肢动物构成了现存动物的一半以上 地球上的物种;它们不仅从生物学的角度来看很重要， 而是作为疾病媒介，以及农业、森林和家庭害虫。 昆虫之间、昆虫与植物、昆虫与动物之间 宿主和捕食者 本项目旨在阐明 这些化学反应。 对于节肢动物本身的注意 不仅对腺体物质，而且对全身性物质， 可能在节肢动物防御中发挥重要作用的组分和/或 通信 数百万年来，植物一直与昆虫共同进化， 这两类生物之间的化学关系非常丰富 也很有趣 我们对植物的研究将强调隔离， 新型驱虫剂的特性和植物的利用 生物碱作为昆虫防御剂和信息素前体。 在所有情况下，具有可证实的生物活性的新化合物将被 分离并表征。 将进行化学合成， 确认结构并为生物测定提供材料。 整体 这项工作的目标是增加我们对自然的理解， 监管机制，并为新的控制技术提供基础 病媒或其他害虫。

Insects and other arthropods constitute over half of the living animal species on earth; they are important not only from a biological viewpoint, but as disease vectors, and as agricutural, forest, and household pests. Insects interact chemically with one another, with plants, with animal hosts, and with predators. This project is concerned with elucidating the chemistry of these interactions. For the arthropods themselves attention will be paid not only to glandular substances, but also to systemic components that may play important roles in arthropod defense and/or communication. Plants have been co-evoloving with insects for many millions of years, and the chemical relationships between these two groups of organisms are rich and interesting. Our work with plants will emphasize the isolation and characterization of new insect repellents, and the utilization of plant alkaloids as insect defensive agents and pheromone precursors. In all cases, new compounds with demonstrable biological activities will be isolated and characterized. Chemical syntheses will be carried out to confirm structures and to provide material for bioassays. The overall objectives of this work are to increase our understanding of natural regulatory mechanisms, and to provide the basis for new control techniques of disease vectors or other pests.
