• The effects of temperature on some of the life cycle parameters of Paracentrobia andoi were studied in a rearing experiment at constant temperatures, 20℃, 24℃, 28℃, and 32℃ under 16L-8D. The developmental period from egg to adult emergence shortened as the temperature was raised. The threshold temperature for development was about 13℃, and thermal constant was 202.06 day-degrees. Adults at 20℃ survived significantly longer than those at other temperatures, but there was no significant difference at 24℃, 28℃ and 32℃. The fecundity at 32℃ was significantly lower than that at other temperatures, but again, no significant differences were seen at 20℃, 24℃ and 28℃. Life cycle parameters also were calculated and compared. The intrinsic rate of increase (r_m) and capacity for increase (r_c) rose when the temperature was raised. These results are discussed from the standpoint of the parasitoid's capability as a natural enemy of N. cincticeps.
