摘　　要：雀茸毒蛾Dasychira melli是杉木偶发性害虫。林间调查与室内饲养相结合,对湘南地区杉木林中雀茸毒蛾的生活史和生活习性进行观察,采用无人机和直升机喷洒测定3种药剂的林间防效。结果表明:雀茸毒蛾在湖南南部地区1 a发生3代,幼虫危害期分别为5月上旬至6月上旬,7月上旬至8月上旬,8月下旬至10月初。直升机施用2%阿维·苏云金杆菌可湿性粉剂(WP)150,225 g/hm2或0.5%甲氨基阿维菌素苯甲酸盐乳油(EC)900 mL/hm2防治雀茸毒蛾,药后11 d防效均超过90%,且无显著差异。Dasychira melli is an occasional pest of cedar.Forest investigation and indoor breeding were used to explore the life history and living habits of D.melli in southern Hunan province.Meanwhile,the effects of three kinds of insecticides on D.melli in forest were tested by spraying with UAV and helicopter.The results showed that D.melli had three generations a year,and larvae damage periods were from early May to early June,from early July to early August,and from late August to early October.Helicopter application of avibacterium·thuringiensis 2%wettable powder(WP)with the dosage of 150,225 g/hm2 and mecamectin benzoate 0.5%emulsifiable concentrate(EC)with the dosage of 900 mL/hm2 showed good control effect and reached more than 90%after 11 days,and there was no significant difference.
