摘　　要：为筛选防治甘薯麦蛾的有效药剂,田间试验测定乙基多杀菌素、苏云金杆菌、阿维菌素等3种生物农药和氯虫苯甲酰胺、茚虫威、甲氨基阿维菌素苯甲酸盐等3种化学农药对甘薯麦蛾的防治效果。结果表明,生物农药60g/L乙基多杀菌素SC控虫效果和保叶效果均最好。药后1d、4d、10d防效分别为90.92%、91.99%、93.05%;药后4d、10d的保叶效果分别为88.15%、90.89%。化学农药200g/L氯虫苯甲酰胺SC对甘薯麦蛾的防效最好。In order to screen effective pesticides for the control of Brachmia macroscopic Megrick,field trials were carried out with three kinds of biological pesticides(spinetoram,bacillus thuringiensis,avermectins)and three kinds of chemical pesticides(chlorantraniliprole,indoxair conditioningarb,emamectin benzoate).The results showed that spinetoram 60 g/L SC could control Brachmia macroscopic Megrick effectively,the control effects on the first,fourth and 10th day after spraying were 90.92%,91.99%,93.05%,the leaf retention effects on the fourth and 10th day after spraying were 88.15%and 90.89%,respectively.The control effect of chlorantraniliprole 200 g/L SC was the best anong the chemical pesticides..
