Abstract
Developmental periods for the immature stages of Metaseiulus occidentalis (Nesbitt) at naturally occurring diurnal temperatures were obtained in an isolation cage at a shaded outdoor location. The observed temperatures within the cage were used as input into a variable temperature developmental model, and the model output was compared to the observed developmental periods. Observed and estimated developmental periods were in close agreement. The simulation model was then extended to include a function relating developmental periods to rm for both M. occidentalis and its prey, Tetranychus mcdanieli McGregor. Estimated rm values for both species at the same fluctuating temperatures were compared to determine relative favorability of various diurnal temperature cycles.
