Abstract: Experiment was carried out to select the method suitable for raising rice planthoppers in large quantity for insecticide resistance selection. Results showed that among the methods tested, seedling soilless cultured at 20-25℃ served the turn of raising large numbers of planthoppers. When various insecticide application methods were used, both the methods of topical treatment and spraying insecticides on seedlings together with planthoppers could speed up the development of resistance to methamidophos. For convenience, the later was recommended for the insecticide resistance selection with large population of planthoppers.

摘要: 就几种新鲜稻苗对褐飞虱和白背飞虱生长发育和繁殖的影响进行了比较,发现20~25℃下无土培育的幼苗最适合室内稻飞虱生长、发育和繁殖,适合室内飞虱的大批量饲养。通过不同筛选方法对褐飞虱和白背飞虱进行抗性筛选,比较不同方法的筛选效果,发现稻苗和飞虱同时喷雾的方法操作方便、抗性发展快,最适合于大量飞虱的抗性筛选。
