常州地区抗性桃蚜综合防治试验效果研究

Study on Comprehensive Control Effect of Resistant Myzus persicae in Changzhou Area

为探明不同综合防治方法对抗性桃蚜的防控效果,在常州地区防治桃蚜最为关键的两个时期(露红期、谢花期)进行对比试验。结果表明,通过不同药剂处理方式均可对抗性蚜虫起到较好的防治效果,由此可知,防治桃蚜的重要抗药性治理策略依然是轮换使用不同作用机制的杀虫剂。

In order to find out the control effect of different integrated control methods against resistant Myzus persicae,control zones A,B,conventional pesticide control zone C and blank control zone CK(only fungicides were used for control)were set up in the two most critical periods of Myzus persicae control in Changzhou.It can be seen that although the Myzus persicae has developed resistance to a variety of insecticides and the selection range of farmers is limited,the important resistance management strategy for the control of Myzus persicae is still to rotate insecticides with different action mechanisms and carry out comprehensive management.
