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。 There are 28 kinds of parasitic wasps in the chestnut bee, all of which are small bees, and their main species are 10 species. This article gives a brief description of their identification features. Among the parasitic wasps, there are both unipivorous and oligotivorous; both primary and secondary parasites; parasitic in vitro and parasitic in the body. Among them, there are only 4 to 5 dominant species that can affect the population density change of the gallnut bee, and occupy a certain niche in different parasitic environments. The total parasitism is dominated by the Chinese long-tailed wasp Cyclophilus population density of the cyclical changes.
