| Abstract: | The predatory phytoseiid mite Amblyseius swirskii (Athias-Henriot) completed its lifespan when fed on females of the broad mite, Polyphagotarsonemus latus (Banks). The development was the quickest and the number of prey consumed was highest when individuals were reared at 28?°C compared with 19?°C. The average number of eggs/female/day was 2.36 and 1.69, respectively. Life table parameters showed that the population of A. swirskii multiplied 16 and 20 times in a generation time of 22 and 18?days at 19 and 28?°C, respectively. Under these conditions, the intrinsic rate of increase (rm) was 0.139 and 0.170 individuals/female/day, respectively. |
