美国白蛾天敌研究进展

Research progress on natural enemies of the Hyphantria cunea(Drury)

美国白蛾Hyphantria cunea(Drury)是国家林业和草原局的重点防控对象,也是我国重大外来林业检疫性有害生物。现阶段美国白蛾在我国的种群密度持续增加和扩散,缺乏有效天敌的控制应该是重要的原因之一。本文综述了国内、外美国白蛾的捕食性和寄生性天敌的种类。捕食性天敌主要包括昆虫、蜘蛛、两栖类和鸟类,整理出国外报道的捕食性天敌名录119种,国内捕食性天敌名录29种;寄生性天敌主要包括寄生蜂和寄生蝇类,整理出国外报道的寄生性天敌名录47种,国内寄生性天敌名录53种。本文回顾了我国在美国白蛾天敌利用方面取得的阶段成果,并针对将来天敌复合体的应用和原产地天敌的引进提出了展望。

The fall webworm is a key target of the prevention and control issued by National Forestry and Grassland Administration,and it is also a vitial invasive quarantine pest in China.Lacking of effective natural enemies control should be one of the major reasons,regarding to increase and spread of fall webworm population density in recent years in China.This review summarized the species of predatory and parasitic natural enemies of the fall webworm at domestic and overseas.There were mainly four sorts of predatory natural enemies,including insects,spiders,amphibians and birds.A list of 119 predatory natural enemies reported abroad and 29 domestic predatory natural enemies have been completed.There were mainly two sorts of parasitic natural enemies,including parasitic wasps and parasitic flies.A list of 47 species of parasitic natural enemies reported abroad and a list of 53 species of domestic parasitic natural enemies have been completed.Reviewing the achievements in China about the utilization of natural enemies to the fall webworm,and we put forward to the prospects in application of natural enemy complexes and the introduce of natural enemies from origin.
