摘　　要：通过使用溴氰菊酯4个浓度药剂对松沫蝉(Aphrophora flavipes Uhler)若虫进行防治试验,结果表明:施药后1天防治效果都在70%以上,施药5 d后,2 000倍、1 000倍、500倍都在89%以上。吡虫啉3个浓度药剂的防治效果在60%~73%,树干注药初期药效较慢,注药后5 d的防治效果才达到90%以上,树干注药对其他昆虫和环境的危害较小,有利于保护生态环境。By using four concentrations of deltamethrin to control Aphrophoraflavipes nymphs,result shows that the control effect is more than 70%one day after application;after five days of application,2 000,1 000&500 times the control effect are all above 89%.The control effect of the three concentrations of imidacloprid is 60%-73%.The effect of the initial injection of the trunk is slower.The control effect is more than 90%after the injection five days later.The damage of the trunk injection to other insects and the environment is more small,it is conducive to protecting the ecological environment.
