Development temperature mortality survival rate Tetranychidae


Southern red mites, Oligonychus ilicis (McGregor) reared on holly, Ilex crenata Hetzii , completed egg-to-adult development at constant temperatures from 15.5 to 35.0°C. Developmental times generally decreased as temperatures increased and developmental curves for ali stages were cubic. Maximum reproductive potential occurred at 26,5°C and length of the pre-, post-and ovipositional periods decreased as temperatures increased. Mortality for both male and females was minimized at 21.0°C. Survival rate of O. ilicis was highest for eggs and greatest mortality occurred in the larval stage. Mean generation time was shortest at 35 and longest at 21 oc, and the net reproductive rate and the intrinsic rate of natural increase were highest at 26.5°C.
