CHEMISTRY OF ARTHROPOD SECRETIONS

昆虫和其他节肢动物占活着动物的一半以上 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，以及作为农业、森林和家庭害虫。 昆虫之间、与植物、与动物之间相互作用 寄主和捕食者。这个项目致力于阐明 这些相互作用的化学。对于节肢动物本身的关注 将不仅付给腺体物质，而且还付给全身 可能在节肢动物防御和/或中发挥重要作用的组件 沟通。 植物与昆虫共同进化已有数百万年的历史， 这两类生物之间的化学关系非常丰富。 而且很有趣。我们对植物的研究将强调隔离和 新型驱虫剂的表征及其在植物中的应用 生物碱作为昆虫防御剂和信息素前体。 在所有情况下，具有明显生物活性的新化合物将被 与世隔绝的，有特点的。将进行化学合成以 确认结构，并为生物分析提供材料。整体而言 这项工作的目的是增加我们对自然的了解 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.
