Abstract

Dévelopment and reproduction of commercially obtained Amblyseius cucumeris (Oudemans) (Acarina: Phytoseiidae) and Orius insidiosus Say (Heteroptera: Anthocoridae) reared on western flower thrips (WFT), on English cucumber were studied at several constant temperatures within the range of normal variation in a greenhouse. Data were used to estimate the parameters of regression models describing the rates of development and population increase as nonlinear functions of temperature, under conditions of unlimited prey availability. An independent test was also conducted to verify model predictions of the thermal responses of A. cucumeris development under two regimes of daily temperature fluctuation following a sine wave pattern with an 8°C amplitude. The validity of the models was found to be adequate, with an error rate <6%.
