The green lacewing, Mallada boninensis when fed on sterilized and unsterlized eggs and neonates of Corcyra cephalonica recorded the survival of immature stages (l_x) to the extent of 0.69, 0.74 and 0.42 per individual within a pivotal age of 28, 29 and 28 days, the net reproductive rate (R₀) to the tune of 243.46, 282.35 and 124.90 females per female per generation, the mean length of generation time (T) to the extent of 48.03, 50.22 and 44.23 days, innate capacity for increase in numbers to the tune of 0.1143, 0.1123 and 0.1092 female per female per day and finite rate of increase in numbers (λ) to the extent of 1.30, 1.29 and 1.28 females per female, respectively. On reaching stable age-distribution the population of M. boninensis on sterilized eggs of C. cephalonica in egg, larval, pupal and adult stages contributed to the extent of 52.18, 38.51, 6.60 and 2.71 per cent, respectively. The corresponding figures for unsterilized eggs and neonates of C. cephalonica were 51.12, 38.76, 7.41 and 2.70 and 49.03, 43.32, 5.49 and 2.15.
