A field study was carried out during 2015 at Mohammad Bukhsh Dahar Farm, Bakrani District Larkana, to examine the effect of plant extract and synthetic insecticides against insect pests of cabbage crop. Four treatments with three replications were applied. The treatments were: T1=Chemical control Confidor20% SL (Imidacloprid), T2= Neem, T3= Tobacco, T4= Untreated (Control). Two insect pests were found infesting cabbage including white flies and thrips. Pretreatment- and post-treatment observations were recorded. The results revealed that against thrips, the first spray of chemical control (Confidor) showed highest reduction percent (84.62%) followed by Neem (76.62%), Tobacco (74.76%), and lowest for untreated control (6.14%); while in the second spray, chemical control (Confidor) showed highest effect against thrips (87.33%); followed by Neem (79.96%), Tobacco (78.32%) and least by untreated plot (2.61%). Against Whitefly, similar pattern found in chemical control (Confidor) which showed highest effect (78.68%), followed by Neem (62.01%), Tobacco (55.35%) and untreated control (8.27%). After second spray, chemical control (Confidor) showed highest reduction percent (85.19%) followed by Neem (71.12%), Tobacco (63.96%) and the lowest was resulted by untreated control (4.46%). Chemical control (Confidor)showed its superiority in effect to combat sucking insect pests studied in cabbage, followed by Neem, Tobacco and untreated control remained the least.
