The cabbage aphid, Brevicoryne brassicae Linnaeus is a pest of many plants of the Brassicaceae family including cabbage, Brassica olearacae Linnaeus, 1753. We investigated the effect of temperature on the biological parameters of B. brassicae using different temperature-based models incorporated in the Insect Life Cycle Modelling software (ILCYM). Nymphs of first stage were individually placed in the incubators successively set at 10C, 15C, 20C, 25C, 30C, and 350C; 75±5% RH and L12: D12 hours photoperiods. We found that 1st nymph reached the adult stage after 18.45±0.04 days (10°C), 10.37±0.26 days (15°C), 6.42±0.07 days (20°C), 5.076±0.09 days (25°C) and 5.05±0.10 days (30°C); and failed at 35°C. The lower lethal temperatures for B. brassicae were 1.64C, 1.57C, 1.56C, and 1.62°C with a thermal constant for development of 0.88, 0.87, and 0.08, 0.79 degree/day for nymph I, II, III and IV respectively. The temperature 10, 30 and 35°C were more lethal than 15, 20 and 25°C. Longevity was highest at 10°C (35.07±1.38 days). Fertility was nil at 30°C and highest at 20°C (46.36±1.73 nymphs/female). The stochastic simulation of the models obtained from the precedent biological parameters revealed that the life table parameters of B. brassiace were affected by the temperature. The net reproduction rate was highest at 20°C and lowest at 30°C. The average generation time decreased from 36.85±1.5 days (15°C) to 6.86±0.1 days (30°C); the intrinsic rate of increase and the finite rate of increase were highest at 25°C. In general, the life cycle data and mathematical functions obtained in this study clearly illustrate the effect of temperature on the biology of B. brassicae. This knowledge will contribute to predicting the changes that may occur in a population of B. Brassiace in response to temperature variation.
