Investigations conducted to evaluate four strains (Bb-13, Bb-11, Bb-5A and Bb-n) and two local isolates (Bb-L-1 and Bb-L-2) of Beauveria bassiana Vuillemin for their biological properties and pathogenicity against third instar larvae of Spodoptera litura fabricius, showed that the strain Bb-5A was superior with signifcantly higher radial growth, higher conidial concentration, low TG50, high spore viability and high pathogenicity. The strains Bb-13, Bb-11 and Bb-N recorded moderate performance.
