摘  要:
本文以栎黄枯叶蛾两种寄主植物沙棘和虎榛子作为研究对象,通过寄主偏好性与产卵选择性试验确定栎黄枯叶蛾对两种寄主植物的偏好性,并利用动态顶空吸附及GC-MS法对两种寄主植物挥发物进行初步分析鉴定,找出各自的特有组分进行行为反应试验测定以初步分析偏好性原因。结果表明:成虫对虎榛子偏好性较强,对特有组分的行为反应测定中,虎榛子中的α-法尼烯、肉桂醛引起栎黄枯叶蛾成虫产生完整行为反应的数量显著多于沙棘中的组分引起完整行为反应的数量,这可能是栎黄枯叶蛾更偏好于虎榛子的原因。本研究结果可为进一步明确植物挥发物组分与昆虫行为反应之间的关系奠定基础,为有效防治栎黄枯叶蛾提供依据。

摘  要:
In this text we determined the host preference and selectivity of Trabala vishnou gigantina to two host plants Hippophae rhamnoides Linn.and Ostryopsis davidiana Decne.We detected the volatile composition of the two plants by dynamic headspace adsorption and GC-MS and tested the behavioral responses of T.vishnou gigantina to these components.The results showed that adults of T.vishnou gigantina preferred O.davidiana to H.rhamnoides.The results of behavioral response test showed thatα-farnesene and cinnamaldehyde in O.davidiana could elicit behavioral responses from most adults,significantly stronger than the components in the sea buckthorn;the reason might be that O.davidianais more preferable for T.vishnou gigantina.The results can further define the relationships between the plant volatile components and insect behavior,and provide the basis for effectively prevent and control T.vishnou gigantina.
