摘　　要：利用生绿历杀虫剂、1．8％阿维菌素、1．2％苦·烟乳油3种生物农药对灰斑古毒蛾Orgyia ericae Germar．2～4龄幼虫进行了林间防治试验。结果表明，生绿Bt杀虫剂525g／hm^2对灰斑古毒蛾的防治效果为82．46％，最为经济有效；1．8％阿维菌素450mL／hm^2-150mL／hm。对灰斑古毒蛾的防治效果在80．04％～100％之间，其中1．8％阿维菌素300mL／hm^2的防治效果最好。1．2％苦·烟乳油3种浓度的防治效果均为100％。Three pesticides, Bacillus Thuringiensis （Bt）, 1.8% abamectin and 1.2% matrine, were used against the larvae of Orgyia ericae Germain in the 2nd-4th instar in the forest. The results showed that the control effect of Bacillus Thuringiensis （Bt） at the dose of 525 g/hm^2 was 82. 46% and 1.8% abamectin at the doses of 450 mL/hm^2, 300mL/hm^2 and 150 mL/hm^2 could kill 98.19%, 100% and 80. 04% of the pest respectively; killing effects of three concentrations of 1.2% matrine were all 100%.
