摘　　要：草地贪夜蛾Spodoptera frugiperda(J.E.Smith)是2019年新入侵我国的一种重大迁飞性农业害虫。田间监测时,其覆毛卵块易与绒茧蜂茧块混淆。本文利用数码显微系统(VHX-6000,KEYENCE)对草地贪夜蛾覆毛卵块和绒茧蜂茧块的识别特征进行了观察与描述,发现两者在颜色、质地、形状等方面具有明显差异。掌握这些区别特征,有利于提升田间草地贪夜蛾卵的调查准确率。Spodoptera frugiperda(J.E.Smith),a vital migratory insect pest to corn,has invaded China in 2019.When doing survey in field,scales-covering egg mass of S.frugiperda were tended to be confused with fuzzy cocoons lump of Apanteles sp.In order to provide the exact recognition features between them,digital microscopy(VHX-6000,KEYENCE)was used to observe and describe the identification characteristics of scales-covering egg mass and cocoon block.Results showed that there were obvious differences in color,texture and shape between them.We believe that characteristics mentioned in this article are helpful to improve the accuracy of investigation on the eggs of S.frugiperda in the field.
