An experiment was conducted to evaluate the effect of pepper powder, solvent extracted piperine and clove oil against pulse beetle Callosobruchus maculatus in stored green gram at the Post Harvest Technology Center, Bapatla, Guntur District, Andhra Pradesh during 2015 and 2016. There were eleven treatments viz., pepper powder mixed with grain at four different doses i.e., 0.1, 0.2, 0.3 and 0.4% (w/w), pepper powder in sachet @ 1 g and 2 g, cotton swab impregnated with piperine solution @ 3.0% (w/v), plywood piece impregnated with piperine solution @ 1.5% and 3.0% (w/v), plywood piece impregnated with clove oil @ 0.5 ml along with an untreated control. Significant differences were observed among the treatments in population buildup and grain damage due to different doses at exposure times. Grain mixing of pepper powder had a dose response relationship as the adult emergence decreased with dose of from 1 to 4% at all the exposure periods. The mean total emergence and the % grain damage were significantly less in the treatments. Among the pepper treatments, direct mixing of powder with grain was observed to be the most effective over surface placement of piperine extract through plywood pieces or cotton swab.
