| 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。

| Abstract: | The field bioassays of 4 insecticides(15% Imidacloprid DDVP,4.5%Imidacloprid,30?VP omethoate trunk injection and 3?etamiprid 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. |
