草地贪夜蛾的天敌昆虫资源、应用现状及存在的问题与建议

Natural Enemy Insect Resources of the Fall Armyworm Spodoptera frugiperda, Their Application Status, and Existing Problems and Suggestions

草地贪夜蛾Spodoptera frugiperda(J. E. Smith)是原产于美洲热带和亚热带地区的重大农业害虫,具有迁飞快、寄主广、繁殖强、为害重、适生力强等特点。自2019年初入侵我国以来,现已蔓延到我国21个省(市、自治区),草地贪夜蛾将在我国定殖并呈现周年常态化发生态势,对我国玉米产业的发展构成严重威胁。本文综述了草地贪夜蛾的国内外寄生性和捕食性天敌昆虫及其应用情况,并就我国天敌昆虫产业发展的现状和存在的问题提出了建议,以期为应用天敌昆虫防控草地贪夜蛾提供参考。

Fall armyworm,Spodoptera frugiperda(Smith),is a major agricultural pest originating from the tropical and subtropical areas of the Americas.It characteristized by fast migration,broad host range,high reproductive capacity,strong damage ability,and wide adaptability.Nowadays,S.frugiperda has already spread to 21 provinces(city,municipality)in China since it invasion into China at the beginning of this year.It is seriously threating the development of China’s corn industry due to its establishment in China.In this paper,the parasitic and predatory natural enemy insects of S.frugiperda and their application status were summarized.Meanwhile,existing problems and advices for the development of natural enemy insects were suggested.The review is expected to serve as a reference for further studies.
