摘　　要：草地贪夜蛾Spodoptera frugiperda是一种全球重大迁飞性害虫,于2019年首次入侵我国。在西藏自治区调查草地贪夜蛾发生范围及危害情况过程中,容易将草地贪夜蛾与黏虫、棉铃虫、斜纹夜蛾等夜蛾科近缘种相混淆。为了区分草地贪夜蛾及其他夜蛾科近缘种,从寄主植物、危害状、幼虫特征和成虫特征比较了4种夜蛾科害虫,并结合资料进行对比区分,综合分析草地贪夜蛾与其他3种鳞翅目害虫的区别,总结了草地贪夜蛾的关键特征,结果显示4种害虫在幼虫时期特征较为明显,容易区分,建议从幼虫时期进行区分。Spodoptera frugiperdais a global major migratory pest invaded China in 2019 for the first time.In the progress of investigating the occurrence scope and harm of Spodoptera in Tibet,it was found that local farmers and technical staff easily confused the larvae and adults of Spodoptera frugiperda with three kinds of lepidopterous pest such as slime worm,bollworm and Spodoptera.In order to distinguish the noctuid moth and other relative species of noctuidae,four species of noctuidae pests were compared in terms of host plants,damage,larval and adult characteristics.The characteristics of four insect pests in larval stage were easy to distinguish from three other lepidoptera pests.The key characteristics of Spodoptera exigua were summarized in order to provide basis for field investigation and monitoring.
