Compared with the controls, both 10.0-10 000.0 μgL^(-1) of methamidophos and 100.0 μgL^(-1) of 17β-estradiol increased the mean population growth rate significantly.0.1-10 000.0 and 10.0 μgL^(-1) of methamidophos decreased significantly the average ratio of ovigerous to non-ovigerous females and the average mictic rate, respectively, and 1000.0 μgL^(-1) of 17β-estradiol decreased the total resting egg production significantly.

与对照相比，10.0~10000.0μgL^(-1)的甲胺磷和100.0μgL^(-1)的17β-雌二醇均使轮虫的平均种群增长率显著提高；0.1~10000.0和10.0μgL^(-1)的甲胺磷分别显著地降低了实验期间轮虫种群中的携卵雌体数／非携卵雌体数和混交雌体百分率的平均值；1000.0μgL^(-1)的17β-雌二醇显著降低了轮虫的休眠卵总产量。
