摘　　要：草地贪夜蛾Spodoptera frugiperda(J.E.Smith)是一种原产于美洲热带和亚热带地区的世界性害虫,主要为害玉米、高粱、花生和大豆等作物。多食性、高繁殖力、迁飞能力强和易产生抗药性等生物学特性强化了草地贪夜蛾的害虫地位。草地贪夜蛾于2019年1月入侵中国云南等地后迅速蔓延扩散至十多个省份。喷施化学杀虫剂是我国当前有效防控草地贪夜蛾的重要手段,但入侵我国的草地贪夜蛾已携带对有机磷和氨基甲酸酯类杀虫剂的抗性基因,因此需要加强抗药性监测工作,并依据抗药性水平进行精准选药。本文对草地贪夜蛾抗药性测定方法、抗药性发生概况以及抗药性机制进行了综述,并对我国草地贪夜蛾抗药性测定方法和治理策略提出建议。Spodoptera frugiperda(J.E.Smith)is native to tropical and subtropical regions of the Americas but is now a major global agricultural pest.S.frugiperda larvae attack a wide range of crops including maize,sorghum,peanut and soybean.This pest has four characteristics that exacerbate its pest status:polyphagy,high fecundity,strong migratory ability and the ability to develop resistance to insecticides.Since it invaded Yunnan province in January 2019,S.frugiperda is spreading rapidly through a dozen other Chinese provinces.Currently,control of S.frugiperda in China mainly relies on spraying chemical insecticides.However,some of the first S.frugiperda to invade China already carried genes conferring resistance to organophosphorus and carbamate insecticides.There is an urgent need to determine the resistance status of S.frugiperda in China so that the insecticides that are most effective against this pest can be identified and deployed.This paper reviews the monitoring methods and current status of S.frugiperda,and the mechanisms responsible for insecticide resistance in this species.Methods for monitoring and managing resistance in S.frugiperda in China are suggested.
