采用触角电位技术研究了棉铃虫触角对其雌雄两性主要信息素组分的反应。结果表明：雄蛾触角的ＥＡＧ反应明显地高于雌蛾触角；在所测定的各种化合物中，雄蛾对雌性信息素主要组分产生最为强烈的ＥＡＧ反应；在０．００００４～４０μｇ范围内，雄蛾时主要雌性信息素成分Ｚ９－１６：Ａｌｄ和Ｚ１１－１６：Ａｌｄ以５：９５的比例配制成的二元组分产生的ＥＡＧ反应与浓度呈正相关；向含二元组分的滤纸片上加入不同浓度的Ｚ１１－１６：ＯＨ，使雄蛾触角的ＥＡＧ反应明显降低，其反应幅度介于二元组分与Ｚ１１－１６：ＯＨ之间；对雄蛾触角用Ｚ１１－１６：ＯＨ持续刺激，刺激过程对二元组分的反应降低，取消刺激后在５ｍｉｎ之内对二元组分的反应未恢复到用Ｚ１１－１６：ＯＨ刺激之前的水平。
The response of cotton bollworm antennae to the major pheromone components of both sexes was studied by using the antennae technique. The results showed that the EAG response of the male antennae was significantly higher than that of the female antennae. Among the tested compounds, male moths produced the most intense EAG response to the main components of the female pheromone. Within the range of 0.00004 ~ 40μg , The main component of female pheromone composition Z9-16: Ald and Z11-16: Ald male partners when the binary component formulated in the ratio of 5:95 EAG reaction was positively correlated with the concentration; to the binary filter paper Addition of different concentrations of Z11-16: OH on the tablets significantly reduced the EAG response of the male antennae at the antennal angle, with the reaction range between the binary components and Z11-16: OH; Stimulation, the response of the stimulus to the binary component decreased, and the response to the binary component did not recover to the level before Z11-16: OH stimulation within 5 min after the stimulus was canceled.
