摘  要:
通过野外调查和室内饲养,研究重庆市栗瘿蜂寄生蜂的种类及其对寄主种群消长的调控作用,结果表明,在重庆地区栗瘿蜂的主要寄生蜂有9种,分别隶属于膜翅目长尾小蜂科[中华长尾小蜂Torymus sinensis Kamijo、葛氏长尾小蜂Torymus geranial(Walker)、日本大痣长尾小蜂Megastigmus nipponicus Kamijo、斑翅大痣长尾小蜂Megastigmus maculipennis Kamijo、姬黄色长尾小蜂Megastigmus koebelei Ashmead]、旋小蜂科(栗瘿旋小蜂Eupelmus urozonus Dalman)、跳小蜂科(跳小蜂Encyrtidae sp.)、刻腹小蜂科(栗瘿刻腹小蜂Ormyrus sp.)、广肩小蜂科(广肩小蜂Eurytoma sp.),全部为幼虫期体外寄生性小蜂,中华长尾小蜂Torymus sinensis Kamijo为优势种。个体数量较多的中华长尾小蜂Torymus sinensis Kamijo、栗瘿旋小蜂Eupelmus urozonus Dalman和栗瘿刻腹小蜂Ormyrus sp.分别占寄生蜂总个体数量的30.77%,20.98%,18.88%。在重庆地区寄生蜂是控制栗瘿蜂种群数量变动的主要因子。

摘  要:
Based on field investigation an indoor feeding,the parasitic wasps species of Dryocosmus kuriphilus and its control effect on the ebb and flow of parasitic population in Chongqing region were studied.The results showed that there were 9 main species of D.kuriphilus in Chongqing region,which belonged to 5 families.And they were all external parasitoids of larvae.Torymus sinensis Kamijo was dominant among them.The number of T.sinensis,E.urozonus and Ormyrus sp.accounted for 30.77%,20.98% and 18.88% of total number of parasitic wasps,respectively.Parasitoids were one of main factors for controlling the population number changes of D.kuriphilus in Chongqing region.
