【摘要】 小窄径茧蜂 Agathis pumila Ratzeburg是欧洲落叶松鞘蛾 Coleophora laricella(Hübner)的专性内寄生蜂。最适发育温度为 1 5℃～ 2 5℃ ,最佳寄生时间是寄主幼虫的 1龄中后期和 2龄初期。 1 991～ 1 994年我们从美国和加拿大引进释放 ,防治兴安落叶松鞘蛾 C.dahurica Fikv。目前 ,小窄径茧蜂已在辽宁省大伙房实验林场定居 ,但数量较少 ,还没有达到控制住鞘蛾危害的程度。更多还原

【Abstract】 Agathis pumila Rotzeburg is a specific parasitoid of Coleophora laricella (Hübner)in Europe.The optimum temperature for development is 15℃～25℃,the best parasite target is host larvae of late first instar and earlier second instar.We imported A pumila from U.S.A and Canada and released it in China during 1991～1994 to control C dahurica Fikv.on Larix sp..Now, A pumila has already established in Dahuofang Forest Farm,but the density is lower and cant depress the larch casebearer.更多还原
