摘　　要：利用飞机超低量喷雾法防治兴安落叶松鞘蛾。经室内试验和田间试验,选择出1%苦参碱液剂3 000倍液及2010年生产的0.2%的阿维菌素油剂作为飞机防治用药。结果表明:喷药后15 d时,1%苦参碱液剂375 g.hm-2以上喷洒量防治效果可达到95%以上,0.2%阿维菌素油剂2 500 g.hm-2以上喷洒量防治效果可达96%以上,且杀虫具有持效性,有效地减轻了兴安落叶松鞘蛾对落叶松林的危害,防治成本大幅下降。An experiment was conducted to control Coleophora dahurica on larch forest by aerial spraying with ultra-low volume. The optimal biological pesticides and their suitable dosages, 1% matrine and 0.2% abamectin oil, were determined by laboratory and field experiments. Result showed that the control effect of 1% matrine at a dosage of 375 g · hm^-2 reached 95% 16 d after aerial spraying, and that of 0.2% abamectin oil at a dosage of 2 500 g · hm^-2 achieved 96%. The： insecticides effectively alleviated the ilarm to the larch forests due to their sustainable toxicity to C. dahuKca, and the control cost was geatly lowered than before.
