摘要
分别采用浸渍法和玻管药膜法,室内评价了不同虫态小麦吸浆虫对吡虫啉、溴氰菊酯和辛硫磷的敏感性差异。结果表明:不同虫态的麦红吸浆虫对供试药剂的敏感性差异较大,其中,成虫对药剂敏感性最高,幼虫和蛹对药剂敏感性较低。根据研究结果,提出了小麦吸浆虫的最佳防治适期和防治方法。
The sensitivities of Sitodiplosis mosellana stages to imidacloprid,deltamethrin and phoxim were determined by the method of residual film in glass tube and dipping.The results indicated that the adults and immature stages had different sensitivity to insecticides.The adults was most susceptible to insecticides,while the larvae and pupa were not susceptible to the tested insecticides.According to the results,the optimum control period and method were projected.
