白蜡虫孤雌生殖的研究

Study on the Parthenogenesis of Ericerus pela (Chavannes)

白蜡虫在人为去雄虫条件下孤雌生殖的研究表明:白蜡虫子1代和子2代的生物学特征与正常行两性生殖的白蜡虫自然种群孤雌生殖的基本一致;孤雌生殖的子代怀卵量低于正常两性生殖的自然种群雌虫怀卵量;孤雌生殖的子代性比与正常两性生殖的自然种群性比基本相同;子1代的雌虫死亡率低于正常两性生殖的自然种群的雌虫死亡率,子2代的雌虫死亡率与正常两性生殖的自然种群的雌虫死亡率相近;子1代的个体泌蜡量和单位面积泌蜡量与两性生殖的白蜡虫泌蜡相似;子2代的平均个体泌蜡量和单位面积泌蜡量低于正常两性生殖的白蜡虫。

The parthenogenesis phenomenon of Ericerus pela was reported first time . Ericerus pela could make parthenogenesis when the males were wiped off. The research results showed that the biological characters of two generations of the parthenogenesis population were very similar to those of the natural gamogenesis population.Comparing the parthenogenesis with the natural gamogenesis populations, the egg number of parthenogenesis population was lower and the sex ratio was same, while the mortality of the first generation of the parthenogenesis population was lower and the mortality of the second generation was similar to that of the natural gamogenesis population. The quantity of excreting white wax of the first generation of the parthenogenesis population was similar while the second generation was lower than that of the natural gamogenesis population.
