Age-stage two sex life table was constructed for a predatory lacewing, Chrysoperla carnea feeding on 3 different canola feeding aphids; mealy cabbage aphids, Brevicoryne brassicae (L.), mustard aphid, Lipaphis erysimi (Kaltenbach) and green peach aphid, Myzus persicae (Sulzer). The experiment was performed under laboratory conditions at 25± 1oC and 65 ± 1% RH. The immature development duration was shortest on M. persicae (17.3 days). While, C. carnea completed its immature developmental period in 21.1 days, which was longest among other, tested aphids. Similarly, survival of C. carnea was higher on feeding M. persicae and lowest on L. erysimi. Female egg laying of predator was also higher on M. persicae, followed by B. brassicae and L. erysimi. These results show that M. persicae favors the quick development and higher reproduction of C. carnea as compared to B. breassicae and L. erysimi. This information is useful in relation to mass rearing of C. carnea and in biological control of canola aphids by using C. carnea.
