摘要
近年来,新疆塔城地区额敏县野果林遭受苹果巢蛾Yponomeuta padella Linnaeus的严重危害,造成重大经济损失。为寻找其有效天敌,保护这些珍贵的果树资源,2008-2009年,对额敏县野果林苹果巢蛾的寄生性天敌资源展开了调查。通过野外采集及室内饲养,发现了寄生于该害虫卵、幼虫及蛹的3种寄生蜂,即:卵-幼虫跨期寄生蜂——巢蛾多胚跳小蜂Ageniaspis fuscicollis(Dalman),蛹期寄生蜂—黄柄齿腿长尾小蜂Monodontomerus dentipes(Dalman)和幼虫-蛹跨期寄生蜂——全北群瘤姬蜂指名亚种Iseropus stercoratorstercorator(Fabricius);其中巢蛾多胚跳小蜂为优势种,寄生率可达95.98%。本研究为苹果巢蛾的生物防治奠定了基础。
In recent years,the orchard ermine,Yponomeuta padella Linnaeus causes serious damage to wild orchards in Dorbiljin County,Xinjiang.To search for efficient biocontrol agents to protect the rare wild fruit resources from ermine damage,investigation was initiated in 2008-2009 to explore parasitic natural enemies of Y.padella.Through field collection and laboratory rearing,we found three parasitoid wasp species,Ageniaspis fuscicollis（Dalman）,an egg-larva parasitoid wasp,Monodontomerus dentipes（Dalman）,a pupa parasitoid wasp,and Iseropus stercorator stercorator（Fabricius）,a larva-pupa parasitoid wasp.A.fuscicollis was a dominant species,with a parasitism rate of 95.98%.
