摘　　要：扶桑绵粉蚧是一种重要的外来入侵害虫,其分布广、寄主植物多,虫体小,发生危害隐蔽,并与其近似种混合交叉发生危害,野外识别鉴定困难,易暴发成灾,难于防控。本文通过野外调查,采集到多个扶桑绵粉蚧及其近似种石蒜绵粉蚧和双条拂粉蚧。通过制作玻片标本,分别从触角、眼、口器、足、腹脐、刺孔群、盘孔、管腺和体毛等部位比较了3种粉蚧的玻片显微特征以及野外活虫虫体特征,为检疫工作人员快速识别该虫及其近似种提供参考。As an important exotic pest,the mealybugs of Phenacoccus solenopsis Tinsley has wide distribution,many host plants,tiny body,hidden damages and mixed hazards with their related species,so it is difficult to identify and control in the field. In this article,we surveyed and collected many samples of Phenacoccus solenopsis Tinsley and its related species of Phenacoccus solani Ferris and Ferrisia virgata Cockerell. We compared their microscopic characteristics from the antennae,eyes,mouth-parts,legs,circulus,cerarii,disk pores,cylindrical ducts and setae respectively,and living body characteristics. It provides a reference for quickly identified the mealybugs and its related species for the quarantine officials.
