【摘要】 从中国11个省市,20个县采集到23,878个栗瘿瘤,并从中育出各种寄生蜂3999头,共30种,分属11个科。对其中分布广、数量多的中华长尾小蜂Torymussinensis Kamijo,葛氏长尾小蜂T.geranii(Walker),玫瑰广肩小蜂Eurytomarosae Nees,黄褐宽缘广肩小蜂Decatoma concinna(Boh.),黑褐宽缘广肩小蜂D.variegate(Curtis),纵脊刻腹小蜂Ormyrus Punctiger var.rulifanusMayr,栗瘿旋小蜂Eupelmus urozonus Dal marl,栗瘿姬小蜂 Tetrastichussp.等进行了较深入的研究。并且通过虫瘿解剖及幼虫形态鉴别确认了它们之间的、以及它们与栗瘿蜂之间的关系。研究表明,栗瘿蜂天敌在栗瘿蜂种群动态自然调节中起重要作用。更多还原

【Abstract】 In 20 counties,11 provinces and autonomous regions,China,23878 gal-ls were collected,which 3999 parasites(amounting to 30 species) were rea-red from.They belong to 11 famities (Hym.):Torymidae,Eurytomidae,Ormyridae,Eupelmidae,Eulophidae,Elasmidae,Pteromalidae;Encyrtidae,Scelionidae,Braconidae,Ichneummonidae.Among them,Torymus sinensisKamijo,Torymus geranii (Walker),Eurytoma rosae Nees,Decaioma conci-nna(Boh),Decatoma variegata (Curtis),Ormyrus Punctiger var,rulifanusMayr,Eupelmus urozonus Dalman,Tetrastichus sp.,which distribute exte-nsively were studied further more.The relationship between parasites andparasites and chestnut gall wasp was assured.Through dissecting of gallsand identification of parasite’s larvae,it is certain that the natural ene-mies have a great influence on the dynamics of populations of chestnutgall wasp.更多还原
