摘　　要：利用Y-型嗅觉仪研究了草地螟阿格姬蜂对5种幼虫、虫粪的行为反应。与空白对照相比,草地螟幼虫及虫粪对草地螟阿格姬蜂具有显著引诱作用,其他多种幼虫没有显著作用;当5种不同寄主幼虫(或虫粪)两两组合,草地螟阿格姬蜂对其幼虫和虫粪的选择表现不一,并不完全趋向草地螟;适宜条件提供多种幼虫,草地螟阿格姬蜂仅对草地螟幼虫产卵,对其他幼虫不产卵。The behavioral responses of female Agrypon flexorius to volatile compounds emitted by different larve and frass were studied with a Y -tube olfactometer. Compared with blank contrast group, females Agrypon flexorius were attracted to the volatiles from its lavar and frass, and other females were not. When each two of different lavare or frass were combined, the attraction of A.flexorius to different larvar or frass were incoherence; Providing different larvars, A.flexorius only laid eggs on Loxostege sticticalis.
