本文通过点滴法首次测定了贵州省白背飞虱和褐飞虱对几种杀虫剂的抗性水平:白背飞虱对异丙威、吡虫啉和扑虱灵的抗性均是中等抗性水平,褐飞虱对扑虱灵产生了中等水平抗性。
In this paper, the resistance of whitebacked planthopper and brown planthopper to several insecticides in Guizhou Province was determined for the first time by the dot-drip method. The resistance of the white-backed planthopper to isoproxil, imidacloprid and buprofezin were moderately resistant, Nilaparvata lugens produced moderate levels of resistance to bupropion.
