Oil formulation of entomopathogenic fungi Beauveria bassiana for its effect against tobacco caterpillar Spodoptera litura (F.) in six concentrations (1000x105, 700x105, 500x105, 250x105, 125x105 and 75x105) in the form of sunflower oil formulation and conidial suspension of B. bassiana has been evaluated in this study. All the five concentrations showed mortality and maximum mortality was observed at 108 hr after treatment at maximum concentration (1000x105); and the least mortality of 23.33% was observed at the lowest concentration of 75x105. No significant differences were observed between sunflower oil formulation and conidial suspension.
