Abstract: The experiment on symptomatology and pathogenicity of the entomopathogenic fungus, Beauveria bassiana (Bals. -Criv.) Vuill. on Spodoptera litura Fabricius which was conducted at the Department of Entomology and Department of Plant Pathology, College of Agriculture, Navsari Agricultural University, Waghai, Gujarat, India during the year 2020-22. The entomopathogenic fungus B. bassiana was isolated from The Dangs District. Symptoms produced by B. bassiana after application on Spodoptera litura noted fungi started appearing on the integument of the larva, especially on the abdomen. These progressed with the death of S. litura larvae and the larval body was covered entirely by mycelia of B. bassiana fungus. B. bassiana was found to be pathogenic to S. litura which recorded 80.00 percent mortality on the 12^th day after treatment.
