The intrinsic rate of natural increase of the rice weevil in polished rice was estimated to be 0.1759, 0.3242 and 0.4789 per head per week at 20 deg C, 25 deg C and 30 deg C, respectively. The mean generation time was 18.8, 10.9 and 7.1 weeks at the temperatures, respectively. In comparison with the reports published in wheat, the life history phenomena were somewhat different: the rate was lower and the generation time was more sensitive to the temperature in polished rice than in wheat
