Seven insecticides, viz. Megamos 20SL, Actara 25WG, Polo 500SC, Sitara 25WP, Nighaban 20EC, Thiodan 35EC and Confidor 200SL were evaluated at their field recommended doses for their efficacy against whitefly (Bemisia tabaci Genn.) on cotton, at the farmer's field in Dera Ghazi Khan during 2007. The insecticides were applied at ETL's of whitefly. All the test insecticides caused significant mortality of whitefly up to 7 days after treatment. However, the most effective insecticides for whitefly, up to seven days were Megamos and Confidor, while Actara remained least effective and the others showed less than 50 % mortality throughout the experiment.
