Abstract : The investigations were carried out on the shelf life of oil based formulation of B. bassiana (Bb 112) under different storage conditions. The formulation stored under ambient temperature (28 ± 2°C) recorded 587.00 and 216.66 × 108 CFU ml−1, respectively on the day of preparation and after 28 weeks of storage. Pathogenicity tests were performed with oil based formulation of B. bassiana (Bb 112) stored at ambient temperature against S.dorsalis and P. latus. LC50 values against S.dorsalis and P. latus revealed that formulation showed highest virulence with the lowest LC50 values of 1.58 × 105 and 5.20 × 106 spores ml−1, respectively. LT50 values of oil based formulation of B. bassiana (Bb 112) against S.dorsalis and P. latus showed the lowest LT50 value of 78.79 h and 83.39 h, respectively.
