灭幼脲一号致粘虫成虫产卵不育的研究——室内不育研究部分

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.

STUDIES ON CHEMOSTERILANT TH-6040 FOR ARMYWORM MOTH

This new method to control the pests, army worm moth, with the chemo-sterilant TH-6040 has been researched in laboratory since 1980. The insects was fed in Mitlin ways. The results showed that the sterility rate of moth eggs reached up to 99.8% when male and female adults within 1 day after their emergence were treated at concentrations of 5-50ppm, and sterility rates of 99.4-99.0% and 99.6-99.1% were produced when the adults were 3 days after emergence treated at the same concentrations. The effectiveness was quite remarkable and seemed to be independent obviously from days of moth emergence. The results have also the importance and value in practical use for c-ontrolling the migratory army worm moth.
