Life cycle of Aphis glycines Matsumura is characterized as heteroecious and holocyclic. Temperature is one of the most important abiotic factors that can affect development and reproduction of A. glycines. In this study, A. glycines were fed on G. max at five constant temperatures, 27℃, 29℃, 31℃, 33℃ and 35℃. The development and reproduction of A. glycines were studied in the laboratory and the data were compared to controls on G. max at 25℃. The results showed that most of A. glycines nymphs developed into adults successfully at temperature range from 25℃ to 33℃, but only a few nymphs could develop into adult at 35℃. Longevity, fecundity and body sizes of A. glycines adults all decreased gradually when temperature increased from 25℃ to 33℃. Intrinsic rate of increase of A. glycines at 27℃ was as big as that at 29℃, which were bigger than those at 25℃, 31℃ and 33℃. At 35℃, no offspring were deposited by adults. It provided information on development and reproduction of A. glycines exposed to high temperatures, which was important to study the adaptability of A. glycines to environmental temperature and for predicting its dynamics in soybean field in northeast China.
