Abstract: The biological character of Myzus persicae includes available accumulation temperature, starting development point and reproduction rate, et al, which were studied in10 different temperature. The results showed that the first initial nymph stages was from 32.54 days to 5.43 days. Above 28℃, development of Myzus persicae was suppressed because of high tempreture. In 28℃, 30℃ and 32℃ the first initial nymph stages were 6.24, 6.68 and 7.19 days. The linear equation regression analytical results showed that the temperature of the lowest starting development point was 4.86℃ in total period, of which the first initial nymph and adult were 5.15℃and 3.67℃. Simultaneously the equation of nonlinear regression analytical results showed that the temperature of the highest development point was 28.47℃ in total period, of which the first initial nymph and adult were 28.05℃and 27.17℃. The available accumulation temperature was 142.86℃,of which the first initial nymph and adult were 21.95℃ and 22.32℃. The survival rate of initial nymph were from 34.76% to72.92% when tempreture changed from 8℃ to 30℃. In addition, the survival rate of initial nymph was 22.50% in 32℃. The average life-span of adult were from 23.42 to 9.57 days. The highest average reproduction rate was 34.56 in 26℃, but the lowest was 13.71 in 32℃. The results were favorable to migration law of Myzus persicae.
