3种赤眼蜂对二化螟和稻纵卷叶螟性信息素的嗅觉反应
Olfaction Responses of Three Trichogramm Species to Sex Pheromone of Chilo suppressalis and Cnaphalocrocis medinalis
摘要
Abstract
Responses of three Trichogramma species,Trichogrammajaponicun,T.chilonis and T.dendrolimi,in rice ecosystem to synthetic sex pheromone of two main Lepidoptera pests,stripped stem borer Chilo suppressalis (Walker) and rice leaf folder Cnaphalocrocis medinalis (Guenée) were determined using the Y-tube olfactometer.The concentrations of sex pheromone were 0.01,0.1,1,10,100 and 1000 μg.The results showed that the sex pheromone lure of C.suppressalis significantly attracted T.japonicun females,but not significantly attracted T.chilonis females and T.dendrolimi females.The sex pheromone lure of C.suppressalis significantly attracted T.japonicum females,T.chilonis females and T.dendrolimi females only under certain concentration.Those results indicate that the tested Trichogramma species can use host sex pheromone as a cue to search hosts,which may promote Trichogramma species' migration from non-rice habit to rice ecosystem and improve biological control of lepidopteran pests.关键词
