| Abstract | ||||
| Chrysoperla carnea (Stephens), (aphid lion, green lacewing) larvae active predators and feed on aphids and other small insects. It has been used in the biological control of insect pests on crops. While The adults feed on nectar, pollen and aphid honeydew and are not predatory Tracer (Spinosad) is primarily a stomach poison with some contact activity and is particularly active against Lepidoptera and Diptera. In this study, tested the effect of bio-pesticide Tracer on percentage of mortality on different larval instars of aphid lion, The results showed 63% mortality of first instar larvae after 72 h of exposure in high concentration when recorded 52% and 30% mortality of second and third instars larvae after the same time The study has proved that, the mortality percentages for the first instar larvae were high, But they modularity in second instar and no significant in third instar. | ||||
