冻干胡蜂蜂蛹对果蝇寿命和繁殖性能的影响

本实验通过研究胡蜂蜂蛹冻干品对果蝇寿命和繁殖力的影响，证明胡蜂蜂蛹具有延缓衰老和增强繁殖性能的作用。采用乙醚麻醉法，收集8h（小时）内羽化的成虫，选择个体大小相近的雌雄果蝇，在不同浓度的培养基中饲养，每两天观察统计一次果蝇死亡数，直到全部死亡。结果表明，雌雄果蝇在5．0％实验组与对照组的平均寿命比较均具有极显著差异性（P〈0．01），雌雄果蝇在0．2％和1．0％实验组与对照组比较平均寿命差异性显著（P〈0．05），由此可见胡蜂蜂蛹可延长果蝇平均寿命；0．2％，1．0％组的果蝇子代数显著高于对照组果蝇子代数（P〈0．05），5．0％组果蝇子代数极显著高于对照组果蝇子代数（P〈0．01），由此可见冻干胡蜂蜂蛹可增强果蝇的繁殖能力。

The Effect of Freezing-dried Hornet Pupae on the Longevity and Reproductivity of the Drosophila melanogaster

The effect of dietary freezing-dried hornet pupae on the longevity and reproductivity of the Drosphila melanogaster was examined. The imagoes within 8 h after eclosion were collected by ether anesthesia. The female and male of similar size were selected and offered the media with different concentrations of freezing-dried hornet pupae. The death number was counted every two days until all the Drosophila melanogaster died. The results showed that the mean life-span of female or male fruit flies fed on 5.0% hornet pupae was highly statistically longer than that of control group (P<0.01), while the mean life-span of those given 0.2% or 1.0% hornet pupae was statistically longer than that of control group (P<0.05). The number of the filial generation of female or male fruit flies fed on 0.2% or 1.0% hornet pupae was statistically higher than that of control group (P<0.05), while the number of the filial generation of those on 5.0% hornet pupae was highly statistically higher than that of control group (P<0.01). It is concluded that hornet pupae can significantly defer senescent aging, and stimulate reproductivity of Drosophila melanogaster.
