摘　　要：为筛选防治玉米田草地贪夜蛾的高效低毒杀虫剂,在田间比较了10种杀虫剂在玉米田草地贪夜蛾卵孵化盛期至低龄幼虫期进行喷雾施药对草地贪夜蛾的防治效果。结果表明,施药后3 d,60 g/L乙基多杀菌素SC、10%四氯虫酰胺SC、200 g/L氯虫苯甲酰胺SC对草地贪夜蛾的防治效果分别是97.85%、96.99%、90.28%;5%虱螨脲SC、10%溴氰虫酰胺SC的防治效果也分别达89.23%、87.2%。施药后7 d,200 g/L氯虫苯甲酰胺SC和60 g/L乙基多杀菌素SC的防治效果分别为93.16%和83.51%;其他供试杀虫剂对草地贪夜蛾的防治效果均偏低。In order to screen insecticides with high efficiency and low toxicity for the control of Spodoptera frugiperda in maize field,the effects of 10 insecticides on the control of S.frugiperda in maize field were compared between the high hatching stage of eggs and the low larval stage.The results showed that the control effects of 60 g/L spinetoram SC,10%tetrachlorantraniliprole SC and 200 g/L chlorantraniliprole SC were 97.85%,96.99%and 90.28%,respectively,after 3 days of application.The control effect of 5%lufenuron SC and 10%cyantraniliprole SC was 89.23%and 87.2%,respectively.At 7 days after application,the control efficacy of 200 g/L chlorantraniliprole SC and 60 g/L spinetoram SC were 93.16%and 83.51%,respectively.The control effects of other insecticides were low.
