摘要：【目的】美国白蛾(Hyphantria cunea(Drury))原产北美,是我国重要的外来入侵害虫之一,对我国农林业生产、城市生态环境和居民生活造成了很大的影响,但在北美地区美国白蛾是一种危害有限的普通害虫。依据经典生物防治理论,为探索利用原产地天敌防治入侵中国的美国白蛾的可能性,2024年在美国密歇根州兰辛市开展了原产地天敌种类调查。【方法】在样地采集美国白蛾网幕后带回室内饲养,每天记录网幕中出现的天敌种类、数量及生物学特征。【结果】调查结果表明,白蛾姬小蜂(Elachertus cidariae Ashmead)、白蛾悬茧蜂(Meteorus hyphantriae Riley)、白蛾盘绒茧蜂(Cotesia hyphantriae(Riley))为本地区美国白蛾幼虫期最主要的3种寄生蜂,其中白蛾姬小蜂为多寄生容性外寄生蜂,后两者为单寄生容性内寄生蜂。普拉刺益蝽(Podisus placidus Uhler)、多刺阿乔猎蝽(Acholla multispinosa(DeGeer))、黄绿泽猎蝽(Zelus luridus Stal)为本地区美国白蛾幼虫的重要捕食性天敌,其中普拉刺益蝽对美国白蛾幼虫的捕食作用最显著。【结论】根据调查结果,白蛾姬小蜂、白蛾悬茧蜂、白蛾盘绒茧蜂3种寄生蜂可以作为引进备选。
【Objective】The fall webworm,Hyphantria cunea(Drury),which is native in North America,is one of the important invasive pests in China,which has had a great impact on agricultural and forestry production,urban ecological environment and life of residents,but in North America,the fall webworm is a common pest that causes limited damage.Based on classic biological control theory,to explore the possibility of using natural enemies from the original area to control the fall webworm,a survey was carried out from Lansing,Michigan,USA in 2024.【Method】Nets of fall webworm were collected from the sampling sites and brought them back to the laboratory for rearing.The species,quantities,and biological characteristics of natural enemies appearing in the net were recorded every day.【Result】Th results show that Elachertus cidariae Ashmead,Meteorus hyphantriae Riley,and Cotesia hyphantriae(Riley)are the three most important larval parasitoids of fall webworm in this area,among which E.cidariae is a gregarious koinobiont ectoparasitoid,and the other two are solitary koinobiont endoparasitoids.Podisus placidus Uhler,Acholla multispinosa(DeGeer),and Zelus luridus St?l are important predators of fall webworm larvae in this region.The predation effect of P.placidus is most significant.【Conclusion】According to the survey results,E.cidariae,M.hyphantriae,and C.hyphantriae can be used as candidates for introduction.
