Abstract : Gram beetle Callosobruchus maculatus is a serious pest of stored legumes with polyphagous & polyvoltine biological features. Control of the pest is a big challenge to curtail the average annual loss of post harvested legumes upto 250 crores in India (FAO). In the present investigation, effect of black pepper powder (Piper nigrum) in controlling the pest in the form of sprinkle & emulsifier pesticide has been studied on the gram host experimentally subjected to the Callosobruchus maculatus infestation. Very satisfactory result has been obtained which was found statistically significant at both 1% and 5% levels of significance.
