| Abstract |
Field experiments were conducted to evaluate the initial and residual effects of Biofly, Beauveria bassiana and Actra efficiency on the whitefly, Bemisia tabaci (Genn.) by using three sprayer types, knapsack motor sprayer (Arimitsu 25 L/fed.) Conventional sprayer (200 L/fed.), and Rotary sprayer Micron ULV (15 L/fed.) in Mitawa Village, Fakous district in Sharkia Govemorate, Egypt during tomato summer plantation of 2010 season. Results showed that Actra ¾ recommended rate by using Conventional sprayer after three days of the 1st and the 2nd sprays proved to be the most effective against B. tabaci adults (87.5% and 93.5%) reduction, respectively followed by Actra recommended rate and ¾ recommended rate by using Rotary micron ULV sprayer after the 1st spray recorded the same reduction percentage 79.4. Actra recommended rate occurred highest initial effect after three days from the 1st and the 2nd sprays against B. tabaci eggs showing 95% and 94% reduction, respectively, with Conventional sprayer. In general, the average of residual effect after the 1st and the 2nd sprays was significantly different between the tested materials and untreated. It could be concluded that controlling B. tabaci depends mainly on the efficacy of the used insecticide and the sprayer type.
