摘要: 本文用常规及电镜扫描等显微观察方法,系统地研究和描述了板栗瘿蜂的主要寄生蜂(中华长尾小蜂、葛氏长尾小蜂、双刺广肩小蜂、黄褐宽缘广肩小蜂、栗瘿旋小蜂、果瘿刻腹小蜂等)的幼期形态特征。结果表明,它们的卵、老熟幼虫和蛹的形态特征差异明显。老熟幼虫的主要分类特征是:头壳和体表上刚毛着生位置、数量和长短;触角形态;上颚形态和大小;体表结构。卵的主要分类特征是颜色,有无印柄,卵及卵柄长短、卵体形态。利用老熟幼虫的形态特征进行小蜂的类群分类是可行的。

Abstract: Present paper, with optical light microscope and scanning electron micris-cope, deals with the morphological characters of eggs, mature larvae and pu-pae of main parasites of Dryocosmus kuriphilus Yasumatsu (Torymus sinensis Kamijo, T. geranii Walker, Eurytoma rosae Nees, E. setigera Mayr, Decatoma concinna (Bob. ), Eupelmus urozonus Dalman, Ormyrus sp. ). Preliminary resu-lts show that the differences of morphological characters in eggs, mature lar-vae and pupae are obvious. We also dicussed characteristics of mature larva,such as number and length of chaetae in epicranium and body surface, ante-nna shape, morph of mandible, structure of body surface, and the character-istics of egg, such as its colour, egg petiolule and its length, morph of eggbody. So the classification on groups of chalcidoidea by means of morphologi-cal characters of mature larvae is feasible.
