Biological characteristics (durations of different stage periods, life table and reproduction) of green lecewing Chrysoperla carnea (Stephens) on mirid bug Creontiades pallidus were studied in laboratory at conditions of 26±1?C, 65±5% RH and a photoperiodism of 16:8 (L:D) h. In immature stage, the duration of incubation, larval, pupal and total immature periods were determined as 4.15, 8.25, 8.10 and 20.50 days, respectively. In adult satge, the duration of preovipositional, ovipositional, postovipositional periods, and female longevity were 6.82, 35.18, 5.73 and 47.32 days respectively. Total life span of C. carnea was 66.70 days. The results indicated that 88.42% of eggs hatched to larval stage and 45.26% of total population in a cohort (95 eggs) completed their immature period and developed into adult stage. In this study, gross fecundity rate, gross fertility rate, net fecundity rate, net fertility rate, mean eggs/female/day and mean fertile eggs/female/day were determined as 330.76, 270.25, 120.27, 98.15, 6.00 and 4.90, respectively. The highest count of mean reproduction per female per day (11.28 eggs) occured on day 23rd with subsequent observation indicating that most female individuals (85.70 %) survived to this date (day 23rd).
