昆虫化学生态学与植物保护

Chemical Ecology of Insect in Plant Protection

在生态安全条件下进行植物保护,推行植物免害工程是实现可持续发展的有效途径之一。笔者综述了昆虫化学生态学中昆虫与植物之间、昆虫与天敌间的化学联系,信息素与植物挥发性物质在昆虫对寄主植物定位、定居、取食和繁殖中的作用,非寄主植物对植食性昆虫寄主选择的影响等领域的研究进展,以及利用植物次生性化合物进行害虫治理的应用现状。展示了昆虫化学生态学在未来植物保护中的应用前景及昆虫化学生态学的研究方向。

How to protect plants ecologically,compatibly and sustainably is the most concerned issue in the 21st century.Chemical ecology of insect is the theoretical basis of pest control,and the most effective method of pest control sustainably is to carry out plant immune engineering.The plant protectants,repelling insect pest away from the plant,deterring the oviposition of adults and the continuation of feeding,would protect the plants against the pests.The recent advances in chemical interactions among plants,insects and their natural enemies were reviewed in this paper.The roles of pheromones and plant volatiles on the host location,feeding behavior and reproduction potential of insects,and the effects of nonhost on the host selection behavior of phytophagous insects were introduced.And the application strategies of plant allelochemicals and plant protectants in insect pest management were also discussed.The prospects of application of chemical ecology of insect,such as the development of botanical pesticides or plant protectants,the control of insect behavior by using chemical stimuli,the monitoring of pest,and the management of natural enemies,were put forward.Finally,the research directions in chemical ecology of insect in the future were also suggested.
