摘要
本文报道宿主蝇种、蜂蛹比例和蝇蛹日龄对丽蝇蛹集金小蜂寄生率及产子蜂量的影响。该蜂在家蝇、丝光绿蝇、巨尾阿丽蝇和红尾粪麻蝇蛹中的寄生率分别为:85%、92%、76%和14%。蜂蛹最适比例为:1:2.5~5。该蜂可产子蜂于1~7日龄的巨尾阿丽蝇蛹,以1~2日龄蝇蛹产子量最高。
In the laboratory studies, conducted In Taiyuan during 1986-1987, the pupal parasitization of Musca domestica, Lucilia sericsta, Aldrichina grahami and Bercaea haemorrhoidalis by the parasitoid were 8556, 92%, 76% and 14%, respectively. The optimum ratio of the parasitoid to host for controlling the flies was found to be 1:2. 5-5. Female wasps laid their eggs in the host pupae of 1-7 days old, 1-2 days old pupae being the most acceptable for cviposition by the wasps.
