Abstract: Objective To test virulence of compound of Chlorpyrifos and Fendona against Blattella germanica in laboratory.Methods The dropping method,the spraying method and the resort spraying method.Results The half lethal dose(LD50) and the half knock-down time(KT50) of compound of Chlorpyrifos and Fendona were close to or less than on using separately.Toxicity of 1∶1 match was the highest;knock-down effect of 1∶1 or 1∶0.5 match were better;compound by 1∶1 match and dilution by 50 times has effective knock-down function and poison ability in about 90 days,but effects are different depending on different surfaces.Conclusion The compound of chlorpyrifos and Fendona obtained good result and worth of popularizing.
摘要: 目的测试毒死蜱与奋斗呐复配制剂在实验室内对德国小蠊的毒效作用。方法点滴法、直接喷雾法和滞留喷雾法。结果毒死蜱和奋斗呐复配后半数致死剂量(LD50)和半数击倒时间(KT50)均接近或小于两药单独使用。两药复配呈协同作用,其中以1∶1配比毒力最高;以1∶1或1∶0.5配比的击倒效果较好;1∶1配比稀释50倍,滞效期可达90d;不同表面对药效影响有所差异。结论毒死蜱与奋斗呐两药复配,其效果良好,值得推广应用。
