印度谷螟[Plodia interpunctella (Hübner)]幼虫是一种严重的贮粮害虫,危害大米、小麦、玉米、高粱、燕麦、芝麻、大豆、面粉及一些干鲜果品。每年发生的世代数多,繁殖数量大,危害甚烈。但未见有效的防治药剂和防治方法。本试验以室内饲养的印度谷螟幼虫为试虫,以溴氰菊酯和马拉硫磷为供试药剂,用局部点滴施药法进行室内毒力测定。拟选择对印度谷螟有效的药剂和剂量,并同时测定药剂的作用时间和观察试虫中毒后的反应。
The larvae of Plodia interpunctella (Hübner) are a serious grain-storage pest that endangers rice, wheat, maize, sorghum, oats, sesame, soy, flour and some dried fruits. The number of generations that occur each year, the number of breeding, endangering. But no effective prevention and treatment of agents and prevention methods. In this study, indoor indwelling Indian rice borer larvae as test insects, deltamethrin and malathion as test agents, with local drip method indoor toxicity determination. It is proposed that the effective dose and dosage of the pesticide to the Indian rice stem borer be selected, and the action time of the pesticide and the response after the poisoning of the testis are also observed.
