| Abstract This study was conducted to evaluated the efficiency of several insecticides Joker , Actara (Neonicotinoid) , Karate and Cyfluthrin (Pyrethroid) for control Green Peach Aphids Myzus persicae (Sulzer) and Cabbage Looper Trichoplusia ni (Hubn.) in Lettuce Lactuca sativa L. in fall seasons 2010 , Results revealed that Karate and Actara were the upper in percentage efficiency of control M. persicae, it reached to 72.29 and 70.14% respectively, followed by Joker (53.93 % ), While Cyfluthrin was lower efficiency , reached to 17.04%. Green Peach Aphids population decreased to 20.3 , 22.7 ,27.4 and 31.2 insect/ plant in treatments Joker, Actara, Karate and Cyfluthrin respectively, compared with control , which reached to 62.4 insect/plant . The results of efficacy of insecticides revealed that Cyfluthrin was the most affective against Cabbage Looper , its percentage efficiency was 100% , followed by Joker and Actara (56.71and 51.52% respectively), While Karate was lower efficiency , its percentage efficiency was 40.75%. The population of T. ni after treatment with Cyfluthrin, Actara , Joker and Karate were reduced 0.00 , 0.60 , 0.625and 1.10 larva / plant respectively , compared to 1.65 larva / plant in the control. | ||
