| Abstract | ||||
| The common green lacewing, Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae) is best-known as biocontrol agent. The suitability diet was important in mass-rearing and releasing field. C.carnea has a serious role at IPM cultures apposite of aphid and whitefly pest. For this purpose, Schizaphis graminum (Rondani) (Hemiptera: Aphididae), Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae) biotype-B 3rd nymphs stage and Semi artificial diet as prey for Life table parameters was evaluated. All experiments were conducted at 25 ± 5 0C, 60± 5% RH and photoperiod of 16:8 (L:D).This study, the collected data was analyzed by using Jack Knife model and SAS (9.1) soft ware and experimental design was formatted Completely Randomized Design (CRD) and comparison among means followed by Tukey’s HSD post hoc test. The highest Lx (number of individuals alive between age x and x+1) and the lowest dx (numbers dying during the age interval x) were 0.99 and 0.005 (%) that belonged semi artificial diet. Reproductive and stable population parameters such as Net Fertility rate, Net reproductive rate (R0), Gross reproductive rate (GRR), Intrinsic of increase (rm), Mean generation time (Tc) and Doubling time (DT) in aphid, whitefly and semi artificial diets were 244.9±4.1, 170.2±3.4, 364.6±2; 175.43±4.33, 156±5.4, 267±4.8; 0.143±0.005, 0.124±0.004, 0.185±0.002; 34.93±0.47, 38±0.74, 29.79±0.57 and 4.83±0.08, 5.58±0.06 and 3.74±0.05, respectively. According to these results, semi artificial diet was appropriate diet. | ||||
