摘　　要：巢蛾多胚跳小蜂Ageniaspis fuscicollis（Dalman）是危害新疆野苹果林的苹果巢蛾Yponomeuta padella Linnaeus的重要天敌。在新疆额敏县1a发生1代，室内25～30℃条件下需25d完成1代。此蜂产卵于寄主卵内，营多胚生殖。每头雌蜂平均产卵9次，在每头寄主体内可以繁殖出200多头跳小蜂。6月下旬至7月中旬，林间的寄生率约为12％～35％。Ageniaspis fuscicollis （Dalman） was an important natural enemy parasitizing Yponomeuta padella Linnaeus. It occurred one generation a year in Emin County of Xinjiang Uygur Autonomous Region. In laboratory, it could complete one generation with in 25 days at 25-30 ~C. The wasps oviposi- ted in the host eggs on polyembryonic reproduction. One female wasp could oviposit 9 egg masses, and every parasitized host larva could produce more than 200 parasitoid adults. The parasitization of A. fus- cicollis could reach 12%-35% between late June and mid July in the forest.
