利用化学药剂导致害虫不育是防治害虫的一个新途径.1980年以来笔者用灭幼脲一号乳剂采用Mitlin饲食法于室内对粘虫成虫产卵不育做了研究.试验结果表明,用5oppm处理羽化后一天内的雌、雄蛾,交配后所产卵,不育效果达99.8%,几乎全部不育.用5ppm、50ppm同时处理羽化后第三天雌,雄蛾,交配后所产卵,不育效果分别为99.4—99.0%,9.96—99.1%,效果十分明显.不育效果似与成虫羽化天数无明显关系.这一研究结果,对控制迁飞性昆虫为害及其数量变动具有重要意义和实用价值.
The use of chemical agents to cause pest infertility is a new way to control pests.Myphosphatidylserine I since the use of the first emulsion by Mitlin feeding method for the indoor armyworm adults oviposition infertility research was conducted.The results show that the use of Female and male moths within one day after emergence were oviposited after 5oppm treatment, and the infertility effect reached 99.8%, almost all of them were sterile. The female and male moths were treated with 5ppm and 50ppm The results showed that there was no significant relationship between the infertility effect and the number of emergence days of adult eggs.The results of this study have significant effects on the control of migratory insects and their quantitative changes Important meaning and practical value.
