摘要
本文主要选用了哈尔滨地区蔬菜田上常用的几种药剂对小菜蛾和蚜虫的毒力测定。旨在了解本地区的小菜蛾和蚜虫对常用几种杀虫剂敏感度下降的程度 ,为生产上预防和延缓害虫抗药性的产生提供理论依据。
In order to know the reduced degree of susceptibility of Plutella xylostella L. and Myzus persicae to these common insecticides, the study mainly determind toxicities of several common insecticides on Plutella xylostella L. and Myzus persicae in Harbin area. The results can provide fundamental basis for preventing and delaying the development of resistance to insecticcide.
