Twenty isolates each of Beauveria bassiana and Metarhizium anisopliae were tested against the second instar larvae of Plutella xylostella through laboratory bioassay using larval dip method at the concentration of 1×107 conidia/ml. Higher larval mortality of 88.85% and 81.44%, were observed with NBAIR Ma-4 and NBAIR Ma-35 isolates of M. anisopliae and 77.36% with NBAIR-Bb-5a isolate of B. bassiana. Further studies on dose and time mortality with four isolates indicated lowest LC50 value of 2.6×104 conidia/ml and LT50 of 86.6 hours with NBAIR Ma-35 isolate. These isolates have to be further tested against P. xylostella in infested fields of cabbage and cauliflower.
