Abstract: The aims were to clarify the relationship between temperature and adult reproduction and egg development of rice moth (Corcyra cephalonice), carry out mode expression, and provide scientific basis for artificial and intelligent mass production of rice moth and using their eggs for breeding natural enemy insects. Developmental period, rate of hatching progress of eggs and fecundity, oviposition dynamics, and longevity of adults were determined at five constant temperatures (15, 20, 25, 30, 35℃) in the laboratory. The results showed that there was no egg hatching at 15℃. At the temperature range of 20-35℃, the developmental period of eggs was negatively correlated with temperature. Based on the relationship between the development rate and the hatching rate of eggs and temperature, a logistic curve model and a binomial model were established respectively: V=0.25/[1 exp(5.06-0.24t)] (R=0.9993, F=358.06, P=0.0373); y=1/[0.0144 526644.37exp(-t)] (R=0.9471，F=26.14，P=0.0145). At the tested temperature range, rice moth adult exhibited a trend of first increase and then decrease in fecundity with temperature increase, and the relationship between adult fecundity (y) and temperature (t) accorded with the binomial model: y=-2.38t2 128.42t-1383.58(R=0.9941，F= 84.28，P=0.0117). The adult longevity also gradually reduced with temperature increase. The results indicated that the suitable temperature range for fecundity of adult females was 25-30℃, and the optimal temperature was 26.98℃. The suitable temperature range for egg development was 20-30℃, the optimal temperature was 26.90℃.
