The development of Myzus persicae (Sulzer) was studied at temperatures ranging from 15 to 32.5℃ under 70±5% RH, and a photoperiod of 16:8 (L:D). Mortality of 1st-2nd nymph was higher than that of 3rd-4th nymph at the most temperature ranges whereas at high temperature of 32.5℃, more 3-4nymph stage individuals died. The total developmental time ranged from 12.4 days at 15℃ to 4.9 days at 27.5℃, suggesting that higher the temperature, faster the development. However, at higher end temperature ranges of 30 and 32.5℃, the development took 5.0 and 6.3 days, respectively.
