摘　　要：以危害柳树的柳兰叶甲、柳蚜、华北大黑鳃金龟为试验对象,采用15%吡虫啉.敌敌畏注干液剂、4.5%吡虫啉注干液剂、3%啶虫脒乳油和30%敌畏.氧乐注干液剂进行了树干注药的防治试验。结果表明15%吡虫啉.敌敌畏注干液剂和4.5%吡虫啉注干液剂注干后对3种害虫均有较好的防效,其田间持效期可达110 d以上。以0.4 mL/cm树干胸径的注药量春季注射,对一个生长周期内不同发生时间危害柳树枝梢、叶部害虫均有较好的防治效果;3%啶虫脒乳油对华北大黑鳃金龟有较好的防效,其田间持效期也可达110 d,但对柳兰叶甲、蚜虫防效差;30%敌畏.氧乐注干液剂持效期为38 d,对在药效期间发生的柳兰叶甲、蚜虫有较好的防效。The field bioassays of 4 insecticides （15% Imidacloprid＋ DDVP, 4.5%Imidacloprid, 30% DDVP＋omethoate trunk injection and 3 %Acetamiprid EC） were concluded against Plagildera versiclolora, Aphis farinosa and Holotrichia oblita. The results showed that 15% Imidacloprid＋DDVP and 4.5 % Imidacloprid exhibited high efficiency against the 3 insects tested, and provided extended residual effectiveness, up to 110 days under optimum conditions. After trunk injection by the dosage of 0.4mL/cm trunk diameter in spring, the pesticides can control pest occurred different time during one growth periodicity. 3% Acetamiprid could effectively control H. oblita within 110 days. 30% DDVP ＋omethoate had a 38-day residual effectiveness against P. versiclolora and A. farinosa.
