THE ROLE OF PLANT VOLATILES IN TRITROPHICINTERACTIONS AMONG PHYTOPHAGOUSINSECTS, THEIR HOST PLANTS ANDNATURAL ENEMIES

植物挥发性次生物质在植食性昆虫、寄生植物和昆虫天敌关系中的作用机理杜永均，严福顺（中国科学院动物研究所，北京１０００８０）植物挥发性次生物质是一些分子量在１００—２００的有机化学物质，包括烃类、醇类、醛类、酮类、有机酸、内酯、含氮化合物以及有机硫等化...

his paper is a review on recent progress in the researches on the role playedby plant volatiles in tritrophic interactions among phytophagous insects, their hostplants and natural enemies. It summarizes information in the following areas: 1. thephysical and chemical characteristics of plant volatiles, 2. the role of plant volatilesin host selection of phytophagous insects and their natural enemies, their reception byolfactory receptors, and the olfactory code and information processing of stimulatingsignals, 3. synergism of plant volatiles with insect pheromones, 4. production ofplant volatiles induced by herbivore-feeding and their significance in the indirectdefence of host plants, and 5. odor learning of phytophagous insects and their naturalenemies. Presumably to understand the plant volatiles and their role in the interactions can provide the basis in the design of some types of program for insect pestcontrol. Possible application in future pest control is discllssed.
