| 摘 要： | 栗瘿蜂的寄生蜂，在山东有２８种，均为小蜂类，主要种１０种，本文对其识别特征作了简单描述。在这些寄生蜂中，有单食性的也有寡食性的；有初寄生的，也有重寄生的；有在体外寄生的，也有在体内寄生的。其中能对栗瘿蜂种群密度的变动产生影响的优势种只有４－５种，在不同的寄生环境中占有一定的生态位，其寄生总效应是以中华长尾小蜂为核心，主导着栗瘿蜂种群密度的周期性变动。

| Abstract: | 28 species of parasitic wasps of Dryocosmus kuriphilus were found in Shandong Province,which almost belong to chalcidoidea and ten of them are more important.A key to the species is provided.The parasitic wasps are either monoparastic or polyparasitic,eitherprotoparasitic or epiparasitic,either ectoparasitic or endoparasitic.4-5 species of themare more significantly affect the change of the population of Dryocosmus kuriphilus whichoccupy a certain niche in different environments.Torymus sinensis K.which is the most im-portant parasitic wasp leads the periodical change of population density of Dryocosmuskuriphilus. |
