Development, oviposition, and survival of a commercially available predatory mite, Amblyseius swirskii (Athias-Henriot), were investigated to determine the life history parameters when they consumed a diet of cattail (Typha latifolia L.) pollen or tomato russet mites (Aculops lycopersici [Massee]) at 25±0.5 °C and 70±10% RH. Both diets were favorable for development, oviposition, and survival of A. swirskii. Amblyseius swirskii reared on mite prey showed improved performance as compared to pollen. Females laid a total of 26.8 and 38.1 eggs on the pollen and mite diets, respectively. The mortality of female A. swirskii was very low during the first 20 days on both diets, and the cumulative Weibull models that were used to describe age-specific survival and fecundity of female showed a good fit to the data. The net reproductive rate (R_0), intrinsic rate of increase (r_m), and finite rate of increase (λ) of A. swirskii were higher on russet mites than when fed on the pollen diet due to their shorter immature development period and higher oviposition rate. The intrinsic rate of increase (r_m) of the predatory mite was 0.185 and 0.201 on the pollen and mite diet, respectively. The mean generation time (T) and the population doubling time (D_t) were not significantly different for A. swirskii on the two diets. Our results provide life history information for a commercially available A. swirskii using two favorable diets and can be used to compare population growth under other diet sources.

<P>Predation, development, and oviposition experiments were conducted to evaluate Amblyseius swirskii (Athias-Henriot) (Acari: Phytoseiidae) as a potential biological control agent for tomato russet mite, Aculops lycopersici (Massee) (Acari: Eriophyidae), which can be a serious pest of greenhouse tomatoes. Results showed that A. swirskii attacked all developmental stages of A. lycopersici and had a type II functional response at the prey densities tested. The attack rate and handling time estimates from the random predator equation were 0.1289/h and 0.2320 h, respectively, indicating that A. swirskii can consume 103.4 individuals per day. Predation rates of A. swirskii on A. lycopersici in the presence of alternative food sources such as pollen, first-instar thrips, or whitefly eggs were 74, 56, and 76%, respectively, compared with the predation rate on A. lycopersici alone. A. swirskii successfully completed their life cycle on either A. lycopersici or cattail (Typha latifolia L.) pollen. At 25 degrees C and 70% RH, developmental time of female A. swirskii fed on A. lycopersici or on cattail pollen was 4.97 and 6.16 d, respectively. For the first 10 d after molting to the adult stage, A. swirskii fed on A. lycopersici had higher daily oviposition rate (2.0 eggs per day) than on pollen (1.5 eggs per day). From this laboratory study, it can be concluded that A. swirskii has promising traits as a predator against A. lycopersici and that their populations can be maintained using alternative food sources such as cattail pollen. We suggest that the effectiveness of A. swirskii against A. lycopersici under field conditions needs next to be investigated.</P>
