摘　　要：甘蔗二点螟是严重为害我国甘蔗的钻蛀性害虫,化学防治效果不佳且污染环境。其性信息素防治技术早已开始,然而多年田间实验发现其在不同生态型蔗区活性差异很大,可能存在地理变异。本项目提出理论假说,认为二点螟性信息素可能因地理隔离存在组分或含量的地理变异,并给出该假说的理论依据,便于地理变异机制等实验的开展和实施,丰富此类昆虫的化学生态学理论。Chilo infuscatellus is a very important pest in the sugarcane and it is not working to control it by pesticides. Researchers have paid close attention to the application of its sex pheromone. However, the effects of sex pheromone were found different in populations, which delayed the application of sex pheromone in field. One hypothesis is that there may be variation in composition of sex pheromone because of geographic isolation. This paper give the theory basis of this hypothesis to conduct the next experiment and to enrich the study of chemical biology of this species.
