宿主蝇蛹对丽蝇蛹集金小蜂寄生与产子蜂量的影响

INFLUENCE OF SOME BIOLOGICAL CHARACTORS OF THE HOST FLY PUPAE ON THE PARASITISM AND REPRODUCTION OF NASONIA VITRIPENNIS, [HYM.: PTEROMALIDAE] A PARASITOID OF FLIES

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.
