摘　　要：草地贪夜蛾Spodoptera frugiperda(J.E.Smith)是世界性重大迁飞害虫,自2019年入侵我国西南地区后迅速向北扩散,严重威胁我国粮食作物生产安全。挖掘和筛选本地优势天敌,对开展草地贪夜蛾生物防治具有重要意义。2020年夏季在广西南宁市和北海市野外开展草地贪夜蛾及其天敌调查时发现2种草地贪夜蛾幼虫寄生蜂,通过形态学和分子生物学方法鉴定为棉铃虫齿唇姬蜂Campoletis chlorideae Uchida和斜纹夜蛾侧沟茧蜂Microplitis prodeniae Rao&Kurian。本文详细记述了这两种幼虫寄生蜂的形态特征,以期为今后筛选和利用草地贪夜蛾寄生性天敌提供参考。The fall armyworm,Spodoptera frugiperda(J.E.Smith),is a major migratory pest worldwide.Since its invasion in southwest China in 2019,this pest has been spreading rapidly to the north,posing a great threat to the crop production of the country.It is of great importance to survey domestic dominant natural enemies for the biological control of this pest.In the summer of 2020,we found two parasitoid species attacking the larvae of the fall armyworm in the fields of Nanning and Beihai,Guangxi.Based on morphological and molecular evidences,the two larval parasitoid wasp were identified as Campoletis chlorideae Uchida and Microplitis prodeniae Rao&Kurian.The main morphological characteristics of the two species provide reference for the selection and utilization of parasitoid wasps in the control of the fall armyworm.
