摘　　要：通过林间定点和室内饲养观察,共采集到锥栗林栗瘿蜂天敌寄生蜂4科7种,其中中华长尾小蜂在栗瘿蜂天敌寄生蜂数量上占77.2%,为福建锥栗林栗瘿蜂天敌寄生蜂的优势种。在锥栗林进行挂瘿处理,随着挂瘿数的增加,新瘤益害比提高,翌年虫瘿减退率提高。天敌寄生蜂对栗瘿蜂有较强的控制作用,锥栗林可通过增挂虫瘿控制栗瘿蜂种群数量。Based on field investigation and indoor feeding,7main parasitic wasp species of Dryocosmus kuriphilus were collected,which belonged to4families.The number of Torymus sinensis accounted for77.2%among them,which is the dominant species of parasitic wasps of D.kuriphilusin Castanea henryi forests.The insect galls were suspended in C.henryi forests.According to the increasing of suspended gall,the ratio of parasitoid of new galls and decrease rate of galls in next year were increasing.The control effect of parasitic wasps are strong,so suspending galls could be used to control the numbers of D.kuriphilusin C.henryi forests.
