In this study, the developmental duration and life table of Amblyseius (Typhlodromips) swirskii and Amblyseius eharai with the prey Panonychus citri were studied at 25 +/- 1 degrees C. The results showed that the developmental duration of the larval stage and a whole generation of A. swirskii were significantly shorter than those of A. eharai, but no significant differences in developmental duration were observed in other stages. In addition, the larva of A. swirskii could develop into a protonymph without any prey, but prey was necessary for larval development of A. eharai. The fecundity of the adult female of A. eharai was significantly higher than that of A. swirskii. The net reproductive rate (R-o), intrinsic rate of increase (r(m)) and the finite rate of increase (lambda) of A. eharai were higher than those of A. swirskii. The results indicated that A. eharai might be a better competitor compared with A. swirskii according to the parameters of life table.
