中文摘要：

采用专用吸附剂对亚洲小车蝗（Oedaleus asiaticus B．Bienko）成虫体表挥发物进行收集，并通过气相色谱和质谱联用（GC—MS）技术进行了分析。结果表明：亚洲小车蝗雌、雄成虫体表挥发物的组分基本相同，主要含有醛类和醇类，只是各化合物在挥发物中所占的比例不同。其中壬醛和癸醛在挥发物中所占比例较高，雌虫体中分别占56．05％和24．34％，雄虫体中分别占56．48％和22．97％。

英文摘要：

GC - MS analysis identified almost same groups of compounds in the volatile profiles of live male and live female adults of Oedaleus asiaticus collected by special absorbent, which were dominated by aldehydes, alcohols, and alkenes but with different relative contents of each compound in both sexes. Nonanal and Decanal, as the components with higher relative contents of volatile profiles from live adults, accounted for 50.73% and 19.76% in female, and 34.66% and 14.08% in male,respectivelly.
