Abstract

Biopesticides are promising alternatives to chemical pesticides, and they have opened up new panorama in insect pest management to aid in the promotion of safe, eco-friendly pest management. They are relatively host specific and do not interfere with other biotic systems. Research concerning the development of biopesticides has focused mainly on identification of virulent isolates of bioagents for effective management of the target pests. However, information pertaining to their effects on natural enemies, non-target pests, and environment is scanty. In the present study, oil formulation of fungal pathogen, Beauveria bassiana (Bb 112) was tested against adults of Cryptolaemus montrouzieri Mulsant (Coleoptera:Coccinellidae), under laboratory condition. Oil formulation of B. bassiana (Bb 112) has been found to be safer to C. montrouzieri adults with maximum adult survival of 92.62 per cent at the highest dose (108 spores ml-1) and 100 per cent survival at lower dose tested (104 spores ml-1) respectively.
