摘　　要：[目的]探究分月扇舟蛾的生物控制途径。[方法]测定了1%苦皮藤素乳油、0.3%印楝素乳油、苏芸金杆菌(Bt)和分月扇舟蛾颗粒体病毒对分月扇舟蛾幼虫的毒力及林间防治效果。[结果]1%苦皮藤素乳油1 000倍液、1.26×107芽孢/ml Bt悬液和1.36×108颗粒体/ml颗粒体病毒悬液对分月扇舟蛾3龄幼虫的校正死亡率分别为92.17%、92.53%和91.07%。林间防治试验结果表明,1%苦皮藤素乳油1 000倍液和1.26×107芽孢/ml Bt悬液的校正死亡率分别达83.53%～86.59%和84.05%～86.13%,1.52×108颗粒体/ml颗粒体病毒的校正死亡率达89%以上。[结论]为分月扇舟蛾种群数量的生物调控提供了参考。[Objective] The aim was to study the biological control ways of Clostera anastomosis.[Method] Toxicity and forest control effect of 1% celangulin missible oil,0.3% celangulin missible oil,Bacillus thuringiensis（Bt） and granule virus（GV） of C.anastomosis against C.anastomosis larva were determined.[Result] The corrected mortalities of 3nd instar C.anastomosis larvae to diluted 1 000 times of 1% celangulin missible oil,1.26×107 spore/ml Bt suspension and 1.36×108 OB/ml GV suspension were 92.17%,92.53% and 91.07%,respectively.Forest control test result showed that the corrected mortalities of diluted 1 000 times of 1% celangulin missible oil and 1.26×107 spore/ml Bt suspension against C.anastomosis larva were 83.53%-86.59% and 84.05%-86.13%,and the corrected mortality of 1.52×108 OB/ml GV suspension was over 89%.[Conclusion] The research result provide reference for biological control ways of C.anastomosis populations.
