摘　　要：通过1999、2000两年时间调查,发现温州郊区十字花科蔬菜害虫寄生蜂共计10种,并对菜蛾绒茧蜂Cotesiaplutellae和啮小蜂Oomyzussokolowskii的田间自然消长动态进行较为系统的研究,结果表明:温州郊区该两种寄生蜂在不同季节的田间自然寄生率,一年中6～7月和9～11月为两个发生高峰;非防治区菜蛾绒茧蜂和啮小蜂的平均寄生率分别为18.2%和16.0%,而菜农防治区则分别仅为4.1%和2.8%,表明化学杀虫剂对这两种寄生蜂有较强的杀伤力。In 1999—2000, the species of parasitoids of crucifer vegetable pests, and the population fluctuation of Cotesia plutellae and Oomyzus sokolowskii in the suburb areas of Wenzhou were investigated.The results shown there were ten parasitic species of parasitoids.The rates of parasitization of Cotesia plutellae and Oomyzus sokolwskii in the fields showed two peaks all year around in JuneJuly and SepteberNovember respectively. Furthemore, rates of parasitization of C.plutellae and O.sokolowskii in the nospraying area were 18.2% and 16.0%, respectively, nowever, rates of parasitization of C.plutellae and O.sokolowskii in the spraying area were 4.1% and 2.8%,Which suggesting that those parasitoids were partly killed by chemical insecticides
