Abstract: The life cycle study on Earias vittella (F.) (=Earias fabia Stoll.), reared in natural conditions at the laboratory , on okra pods throughout one year (1995-1996), revealed that the egg incubation, larval, pupal duration ranged from : 1-5, 6-26 and 5-14 respectively, and the adult male and female longevities both ranged between 8 and 30 days. Egg mortality was 8.13 % at 31.3 + 0.64°C , 67 + 8.93% R.H. and 0.81% at 27.5 + 2.05C and 58 + 7.34% R.H. Temperature did not influence the viability of pupae, the percentage of moth emergence - at all months - ranged between 85.07% and 97.79 %. Unmated females lived longer than mated ones . The moth had 13 generations per year at an average temperature of 28.65 ± 0.98°C and 60.51 ± 0.9% R.H, from October 1995 to September 1996 with an average generation time of 38.55 ± 1.28 days.
