Abstract
Abstract The development, reproduction, and life table of Amblyseius womersleyi (Schicha) were studied at temperatures ranging from 16 to 38°C, 60–70% RH, and a photoperiod of 16:8 (L:D) h. Mortality of A. womersleyi was high in the early developmental stages, and this trend was especially apparent at low temperatures. The developmental threshold for all immature stages was 11.6°C. The total preimaginal developmental time ranged from 48.3 to 316.0 h. The optimal temperature for development was 33°C. The nonlinear shape of temperature development was well described by the modified Sharpe and DeMichele model. The normalized cumulative frequency distributions of developmental times for each life stage were fitted to the three-parameter Weibull function. The 50% adult survivorship occurred at 15-21 d at ≤24°C, and on 7–9 d at ≥29°C. The mean daily fecundity ranged from 0.325 to 2.963 eggs and was fitted by a third-order polynomial equation. The intrinsic rate of increase (rm) ranged from 0.053 to 0.402, and w...
