Biology of rice moth, Corcyra cephalonica (Stainton) was studied under controlled conditions at a temperature of 27 ± 1.8 ⁰C and 70 ± 4.5% relative humidity in laboratory on groundnut variety GG-20, respectively. The mean length of eggs, full grown larva, pupa and adult wing span were 0.39 ± 0.03, 9.37 ± 0.71, 8.56 ± 0.55, 17.45 ± 1.37 (male) and 18.37 ± 1.66 (female) mm, respectively. Duration of egg, larva, pupa and adult ranged from 4.16 ± 0.80, 43.65 ± 4.52, 9.1 ± 0.96, 7.85 ± 0.87 (male) and 8.55 ± 0.94 (female) days, respectively. The average fecundity of rice moth was 202.2 ± 44.57 eggs with a 94% hatching. The survival percentage (S), mean development period (D) and growth index were 90 percent, 58.36 days and 1.54, respectively. The sex ratio of rice moth was 1:1.05.
