Studies on fecundity life tables and age specific distribution revealed that the expectancy of newly deposited egg was similar on the okra fruits under study. The highest net reproductive rate (Ro) of this pest was recorded 185.27 and the intrinsic rate of natural increase in number (rm) ranged from 0.16 to 0.17 females per female per day on okra fruits. Similarly, the finite rate of increase in number was 3.2301 females per female per day on okra fruits. Studies on age-specific distribution of the pest on okra fruits revealed that the contribution of the eggs and larvae to the population was quite high as compared to pupae and adults.
