This paper dealt with the developmental zero, effective accumulated temperature, adult longevity, adult fecundity and specific life table parameters of tachinid fly Carcelia matsukarehae at temperature 15 degrees C, 18 degrees C, 22 degrees C, 25 degrees C, 29 degrees C, and 32 degrees C, relative humidity 70%-85%, and photoperiod L:D = 12:12. The results showed that the developmental zero and effective accumulated temperature for generation were 5.23 degrees C and 525.73 day-degree, respectively. The adult longevity was 1.35-8.06 days without supplying nutrient but water, and while fed with 30% honey water, their longevity could prolong to 9.63-36.42 days. The optimum temperature for oviposition was 23.6 degrees C, maximum eggs laid by a female were 86. The optimum temperature for population growth was 22-25 degrees C. The specific life table parameters of experimental population under temperature 22 degrees C and 25 degrees C were calculated. At 22 degrees C, R0, T0, rc and lambda were 24.89, 37.33, 0.086 and 1.089, respectively, and at 25 degrees C, they were 20.01, 32.38, 0.09 and 1.10, respectively. The maximum LxMx occurred from the 33rd day to the 38th day after adult emergence at temperature 22 degrees C, and from the 29th day to the 34th day at 25 degrees C.
