我国科研人员近期在实验室条件下采用生命表技术研究了氰氟虫腙亚致死剂量(LC25)对小菜蛾阿维菌素抗性和敏感种群的亚致死效应,旨在为小菜蛾对阿维菌素的抗性治理提供理论基础。试验结果表明:氰氟虫腙对小菜蛾3龄幼虫抗性种群的LC50和LC25分别为0.24毫克/升和0.09毫克/升;对敏感种群的LC50和LC25分别为0.20毫克/升和0.07毫克/升。
Recently, Chinese scientists studied the sub-lethal effect of the sub-lethal dose of metaflumizone (LC25) on the resistance and susceptibility of Plutella xylostella to avermectins in laboratory conditions. Mycophenolate resistance management provides the theoretical basis. The results showed that the LC50 and LC25 of metafenozuron for the 3rd instar larvae of Plutella xylostella were 0.24 mg / L and 0.09 mg / L, respectively. The LC50 and LC25 of susceptible population were 0.20 mg / L and 0.07 mg / Rise.
