摘　　要：番茄潜叶蛾Phthorimaea absoluta Meyrick是一种重要的世界性检疫性害虫。2017年8月入侵我国,现已扩散蔓延至我国多个省市,对露地和保护地鲜食番茄生产构成了严重威胁。在田间种植的番茄和马铃薯上,番茄潜叶蛾与同科的马铃薯块茎蛾常混合发生,且形态与取食为害特征相似,较容易混淆,给田间识别带来困难。本文详细描述和比较了番茄潜叶蛾和马铃薯块茎蛾成虫、卵、幼虫和蛹的外部形态及幼虫为害症状。本文将为番茄潜叶蛾和马铃薯块茎蛾的准确识别及田间调查提供指导,还可为这两种害虫的精准测报奠定基础。The tomato leafminer,Phthorimaea absoluta Meyrick,is an important quarantine pest throughout the world.The pest invaded into China in August 2017 and quickly spread to many provinces and cities,caused serious threat to field and greenhouse planting tomato plants.P.absoluta and P.operculella belong to the same family in Lepidoptera with similar morphological characteristics.Moreover,they all infest tomato and potato plants and caused similar feeding damage symptoms,therefore,it is difficult to distinguish P.absoluta and P.operculella in filed.In this paper,the morphological characteristics of adult,egg,larva and pupa of these two pests were described and compared in detail,as well as the difference of the damage symptoms caused by larvae.The results can provide practical guide for the accurate identification and field investigation of the two pests,and lay a foundation for the accurate detection and prediction of the two pests.
