Abstract: 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.
