Abstract
Three entomopathogenic fungi (EPF) viz., Beauveria bassiana, Lecanicillium (=Verticillium) lecanii, and Metarhizium anisopilae at three spore concentration (108, 1010 and 1012 spores/ml) were evaluated for their efficacy against third instar nymphal stage of Bemisia tabaci on soybean cultivar JS 335. The highest nymphal mortality (70.00%) was recorded in EPF L. lecanii, followed by B. bassiana (53.33%) and M. anisopilae (43.33%) at 168 hours after spraying with 1x1012 spores/ml. However, the two lower doses i.e. 1x1010 and 1x108 spores/ml were not as effective as the highest doses even up to 168 spores/ml against B. tabaci third instar nymphs.
