| 摘 要： | 当成蜂饲养密度为300对.笼-1时,子代雌蜂数量占总出蜂量的60.34%;随着成蜂饲养密度的增大,子代雌蜂比例逐渐降低;当成蜂饲养密度达700对.笼-1时,子代雌蜂所占比例降至38.30%.当寄主橘小实蝇卵与寄生蜂雌蜂的比例为5∶1时,寄主发育至蛹期的数量和羽化的寄生蜂数量分别为10.25粒和8.88只;随着寄主卵比例的增大,寄生蜂子代出蜂量也随之增多;当寄主卵与寄生蜂雌蜂的比例增至25∶1后,寄生蜂子代出蜂量不再增多.

| Abstract: | The adult density of Fopius arisanus(Sonan) was one of the important influencing factors to the ratio of female offspring.The ratio of female offspring was 60.34% when the adult parasitoids were 300 couples(♀∶♂=1∶1) per cage,and which decreased with the increasing of rearing density.The ratio of female offspring would decrease to 38.3% as the number of adult parasitoids increased to 700 couples per cage.The average number of host pupae and parasitoid offspring were respectively 10.25 and 8.88 when the ration of host egg to the female parasitoid was 5∶1.Increases in the ratio of host egg to female parasitoid corresponded with increases in the recovery of F.arisanus offspring and reaching a plateau at 25∶1. |
