作者于82年6月从牛粪中采到一批三龄蝇幼虫带回实验室人工饲养,幼虫全部化蛹后到第10天没有羽化出一头成蝇,解剖蝇蛹后发现内为寄生蜂胚胎,故继续培养4天,待寄生蜂羽化后连同蝇蛹壳一起收集。共有蝇蛹47头,其中38头有寄生蜂羽化孔。9头无羽化孔,解剖后4头为未羽化出来的成蝇,5头为已死亡的寄生蜂。蝇蛹壳上的寄生 In June 1982, a batch of larvae of the third instar larvae were collected from cow dung and brought back to the laboratory for artificial feeding. After the larvae were completely pupal, they did not emerge into adult flies on the 10th day. After dissecting the pupae, they found parasitoid Embryos, so continue to cultivate for 4 days, until parasitozoan feather degeneration together with flies pupae shell collection. There are 47 fly pupae, of which 38 have parasitoid feather holes. Nine non-feathering holes were dissected, four were uninductive adult flies, and five were dead parasitic wasps.
