摘要(Abstract):
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。
