为明确河南省漯河地区草地贪夜蛾(Spodoptera frugiperda)的自然天敌资源,在当地春玉米、夏玉米、冬小麦和自生玉米苗等植株上,调查采集草地贪夜蛾幼虫进行室内饲养观察.结果发现有寄生蜂、病原真菌和昆虫病原线虫等天敌类群,寄生率或感染率分别为0～43.75％、0～32.95％和0～23.08％.寄生蜂种类分别为棉铃虫齿唇姬蜂(Campoletis chlorideae Uchida)、台湾甲腹茧蜂(Chelonus formosanus Sonan)、马尼拉侧沟茧蜂(Microplitis manilae)、中红侧沟茧蜂(Microplitis mediator Haliday)和盘背菱室姬蜂[Mesochorus disceitergus(Say)],其中棉铃虫齿唇姬蜂为优势种,占寄生蜂总数量的87.50％;昆虫病原真菌有绿僵菌和白僵菌,以绿僵菌为主.本研究可为当地草地贪夜蛾的可持续绿色防控提供基础数据.
Investigation of the natural enemies on Spodoptera frugiperda(Smith)larvae in the field of Luohe,Henan
To clarify the natural enemy resources of Spodoptera frugiperda in the Luohe area,Henan,we investigated and collected the larvae from local plants,including spring maize,summer maize,winter wheat,and self-grown maize seedlings,for indoor rearing observation.The results showed that the species of natural enemies were parasitic wasps,entomopathogenic fungi,and entomopathogenic nematodes,with a parasitism or infection rate ranging from 0～43.75％,0～32.95％,and 0～23.08％,respectively.The species of parasitic wasps have been identified,including Campoletis chlorideae,Chelonus formosanus,Microplitis manilae,Microplitis mediator,and Mesochorus disceitergus.Of these,C.chlorideae was the dominant species,accounting for 87.50％of the parasitic wasps.The entomopathogenic fungi included Metarhizium spp.and Beauveria spp.,with Metarhizium spp.being the predominant species.This study provided fundamental data for the sustainable control of S.frugiperda in Luohe City.
