Abstract : Laboratory tests were carried out on the effects of various conidial concentrations of Beauveria bassiana on 1st-instar nymphs of the mango pest Drosicha mangiferae. Mortality was noticed after 3 days, and cumulative mortality was found to increase with time for all concentrations. The highest percentage mortality (100% 14 days after treatment) was obtained with the highest concentration (6 × 109).
