Temperature-dependent development, survivorship and reproduction of the cotton aphid, Aphis gossypii on Cucumis sativus L. were evaluated at six constant temperatures (10, 15, 20, 25, 30 and 35°C). Developmental periods of immature stages varied from 20.70 days at 10°C to 3.81 days at 30°C. The population failed to survive at 35°C. As temperature increased, the intrinsic rate of increase (rm) followed a typical asymmetrical dome-shape pattern, with maximum value of 0.419/day at 25°C. Survival of immature stages differed from 55.97% to 93.14% within the range of 10-30°C. The average adult longevity ranged from 8.56 days at 30°C to 17.00 days at 25°C. Three mathematical models were compared for accuracy in predicting the developmental rate of A. gossypii, and estimating its temperature thresholds and optima. The developmental threshold was estimated to be 6.19°C, and the thermal constant was 97.09 degree-days, using the linear model. The Briere 2 and Lactin 2 models were accepted for success to satisfy criteria of goodness-of-fit (residual sum of square and coefficient of determination) and estimable temperature threshold parameters and highly recommended for the description of temperature-dependent development of A. gossypii. No other data are available in using nonlinear models to describe the relationship between temperature and A. gossypii development.
