& Haseeb, M. & Haseeb, M. 1998 Dose-mortality relationship of entomogenous fungus, Beauveria bassiana (Bals.) Vuill. against mango mealy bug, Drosicha mangiferae (Green).. Insect Environment 4(3): 74-75.

Notes: 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 X 109).
