摘要: 采用单雌腺体微量分析技术,对斜纹夜蛾(中国种群)雌蛾腺体的组份进行鉴定,并研究了各组份的个体差异及释放规律,测试了雄蛾对各组份及其混合物的触角电位反应。雌蛾腺体内含有4个组份:Z9, E11-14∶Ac(A)、Z9, E12-14∶Ac(B)、Z9-14∶Ac© 和E11-14∶Ac(D),其比例为100∶27∶20∶27。

Abstract: The sex pheromone components of Spodoptera litura from China were identified by using analytical technique of single female sex pheromone gland. The individual differences, daily changes and scotophase rhythms of these components were studied. Electroantennogram (EAG) responses of male to these components and its mixture were recorded. Four components, Z9, E11-14∶Ac(A),Z9, E12-14∶Ac(B),Z9-14∶Ac© and E11-14∶Ac(D), were found in the female sex pheromone gland at a ratio of 100∶27∶20∶27.
