ABSTRACT
Callosobruchus chinensis is one of the most destructive insect pests of chickpea in storages and renders the grains unfit for human consumption. In current studies, entomopathogenic fungi, Metarhizium anisopliae and Beauveria bassiana were used as the bio-control agents against this economic pest and proved good alternatives to chemicals. Less number of eggs (2 per grain), more number of holes (8.3 per grain), less number of F1 adults (20.3 per jar) and more number of days (7) to 100% mortality of C. chinensis adults were recorded when chickpea grains were treated with the highest concentration of B. bassiana as compared to that of M. anisopliae. These non-chemical control strategies will have significant contribution towards development of commercial formulations of bio-pesticides to be used against this grain beetle and other stored product insect pests.
