摘　　要：甘蔗是草地贪夜蛾的主要为害作物之一。2020年6月,作者调查了我国重要糖料蔗生产基地崇左市蔗田草地贪夜蛾的为害情况,并进行了药剂防治试验。调查发现,草地贪夜蛾主要在甘蔗苗期至拔节初期为害,并可为害蔗田禾本科杂草筒轴茅和象草。药剂防治试验结果表明:12%甲维·虫螨腈悬浮剂900 mL/hm^(2)、2%虱螨脲微乳剂900 mL/hm^(2)+5%甲氨基阿维菌素苯甲酸盐微乳剂900 mL/hm^(2)对草地贪夜蛾有较好的防治效果。调查结果可为广西甘蔗草地贪夜蛾田间危害监测预警及化学防控提供依据。Sugarcane is one of the main crops infested by Spodoptera frugiperda.A survey was made of the infestations by S.frugiperda in the sugarcane field in Chongzuo,an important sugarcane producing area in China,in June 2020,and a pesticide test was conducted to control S.frugiperda.The survey showed that the S.frugiperda mainly infested sugarcane at the stages from seedling to early jointing,and also infested grasses in the sugarcane field,such as Rottboellia cochinchinensis and Pennisetum purpureum.The pesticide test showed that three days after the treatment the(emamectin+benzoate+chlorfenapyr)12%SC(900 mL·ha^(-1)),and Lufenuron 2%EC(900 mL·ha^(-1))+emamectin Benzoate 5%ME(900 mL·ha^(-1))had better control of S.frugiperda.The survey and the pesticide test provide a reference for monitoring and early warning and chemical control of S.frugiperda in the sugarcane fields.
