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。
A total of 23,878 chestnut galls were collected from 11 provinces and 20 counties in China. There were 3999 parasitic wasps cultivated there, a total of 30 species belonging to 11 families. Among them, Torymussinensis Kamijo, T.geranii (Walker), Eurytomarosae Nees, Decatoma concinna (Boh. ), D.variegate (Curtis), Ormyrus Punctiger var. JuulifanusMayr, Eupelmus urozonus Dal marl, Tetrastichussp. And so on. And through the anatomy of larvae and larval morphological identification between them, and their relationship with the chestnut bee. Studies have shown that the natural enemies of chestnut bee plays an important role in the dynamic natural regulation of the chestnut bee population.
