摘  要：
为了深入理解桑天牛Apriona germari虫粪挥发物在桑天牛卵啮小蜂Aprostocetus prolixus寄主定位中的作用,本研究通过嗅觉生测比较分析了取食不同寄主植物(桑树Morus alba、柘树Cudrania tricuspidata和构树Broussonetia papyrifera)的雌雄两性桑天牛成虫的虫粪挥发物对桑天牛卵啮小蜂的引诱活性,并利用热脱附-气相色谱-质谱联用仪(TCT-GC-MS)对不同桑天牛虫粪挥发物的组分进行了分析鉴定。结果表明:取食不同寄主植物的雌性或雄性桑天牛虫粪挥发物对该寄生蜂均具有显著的引诱作用,而不同处理间的桑天牛虫粪挥发物对该寄生蜂的引诱活性无显著差异,这说明寄主植物的种类和桑天牛性别对于桑天牛虫粪引诱该寄生蜂的活性并无显著影响。桑天牛虫粪挥发物主要包括炔类、酮类、醛类、酯类和萜类等化合物;取食柘树和构树的桑天牛虫粪挥发物组分相同,但取食桑树桑天牛的虫粪挥发物组分明显多于取食柘树和构树桑天牛的虫粪。取食同一寄主植物的两性桑天牛的虫粪挥发物的组分及其含量大致相同,表明寄主植物对桑天牛虫粪挥发物的组分有重要影响,而桑天牛性别对其虫粪挥发物组分无显著影响。

摘  要：
The attractive activities of the volatiles from frass of both sexes of Apriona germari feeding on different plants(Morus alba,Cudrania tricuspidata and Broussonetia papyrifera) towards the parasitoid Aprostocetus prolixus was compared by olfactory bioassays,and the components of those volatiles were analyzed by TCT-GC-MS,aiming at deeply understanding of the role of volatiles from frass of A.germari in host location of A.prolixus.The results indicated that the volatiles from frass of female or male A.germari feeding on the different host plants attracted the parasitoid significantly.But the attractive activities towards the parasitoid were not different significantly between different frass,suggesting that the host plant species or the sex of A.germari does not affect the attractiveness of frass to A.prolixus.The volatiles from A.germari frass included mainly alkynes,ketones,aldehydes,esters and terpenes.The components of the frass volatiles of A.germari feeding on C.tricuspidata were the same as on B.papyrifera.However,more volatile components were found in frass of A.germari feeding on M.alba than feeding on the other two species of plants.The components of frass volatiles of both sexes of A.germari feeding on the same species of host plant were roughly the same.The results suggest that the species difference of host plants affects the volatile components of A.germari frass significantly,while the sexuality of A.germari does not.
