摘要
利用触角电位技术 (EAG)研究棉铃虫Helicoverpaarmigera对 17种植物气味物质的嗅觉反应 ,实验结果表明 :棉铃虫雄蛾、雌蛾对所试各种植物气味物质均无明显的嗅觉反应差异 ,不同种类的气味物质能引起不同的EAG反应。对其中的几种植物气味物质进行了引诱产卵实验及田间诱蛾实验 ,结果表明 :某些寄主植物的挥发性次生物质显示出较好的引诱产卵活性 ,且对棉铃虫性诱剂具有增效和协同作用。田间实验数据显示 。
The EAG responses of the female and male adults of Helicoverpa armigera to a range of host-plant volatile components were examined. The results showed that the antennae of both male and female moths could response to a wide variety of host-plant volatile components. There were no significantly different responses between the female and male moth antennae. The oviposition tests showed that the presence of some host-plant volatile components greatly increased the attractiveness for oviposition. The field tests showed the attractiveness of sex pheromone plus host-plant volatile component was significantly higher than that of sex pheromone alone.
