Demographic studies were carried out for Tribolium freemani HINTON on a wheat shorts or wheat flour medium under a laboratory condition (32.5℃ and 73% r.h.). The sex ratio determined at pupal stage was 1 : 1. The mean lonevity of females and males was 329.1 and 346.7 days, respectively. The survivorship curves for both sexes were negatively skewed rectangular type. A female produced ca 1,000 eggs during her enitre life. The intrinsic rate of increase (r_m) was 0.073 per day, the net reproductive rate (R_0) was 351 and the mean generation time (T) 80.6 days. T.freemani had a relatively low age specific reproductive value (v_x) which was retained for a long period. Ecological and pest status of T. freemani, in comparison with other Tribolium species ofstored-product pests, was discussed.
