The sweetpotato whitefly, Bemisia tabaci MEAM1, is a pest known to significantly impact tomato development and yields through direct damage virus transmission. To manage this pest, the current study compared effectiveness of various insecticide rotations. Field trials included rotations involving synthetic insecticides, biochemicals, microbial agents, applied according their labeled highest concentrations. Results indicated that while standard insecticides consistently reduced whitefly egg nymph counts significantly, biopesticide also achieved reductions, although less consistently. This demonstrated traditional chemical treatments remain highly effective, integrating biopesticides containing Beauveria bassiana Cordyceps javanica present viable alternative could mitigate resistance reduce environmental impact. findings suggest potential for optimizing integrated management (IPM) Insecticide Resistance Management (IRM) strategies by incorporating variety modes action sustainably B.
