Development of the rice moth, Corcyra cephalonica (Stainton), from first instar larvae to adults in a whole wheat flour medium, took 40.9 and 43.5 days for males and females, respectively. Adult longevity was 9.1 and 7.0 days for mated and virgin males - 8.3 and 8.0 days for mated and virgin females, respectively. Virgin females laid more eggs than mated ones and as the number of moths per cage increases, the number of eggs decreases. Maximum mating response occurred during the second night after emergence. The mean number of mating per female was 0.9. The mean number of matings per male was 3.2 while that for females was 1.2 at a sex ratio of 4 males:1 female. Multiple mating occurred among about 16 per cent of the females. All investigations were carried out, at 28 degrees C, 65 per cent relative humidity, and LD 14:10 h.
