Effect of botanicals on number of egg laid by Callosobruchus chinensis in stored chickpea

Abstract

An experiment was conducted to test the efficacy of botanicals against pulse beetle in stored chickpea. Eight treatment including untreated control comprising of Cinnamon powder (3 g/kg), Clove powder(3 g/kg), Black pepper seed powder(3 g/kg), Turmeric rhizome powder(5 g/kg), Acorus calamus rhizome (Vekhand) powder (2 g/kg), Acorus calamus rhizome (Vekhand) powder(4 g/kg), Acorus calamus rhizome (Vekhand) powder (8 g/kg) were used against adult pulse beetle, Callosobruchus chinensis on chickpea grains. All botanicals recorded minimum eggs laid by the pulse beetles on the grain treated with than the untreated control. Acorus calamus rhizome (Vekhand) powder (8 g/kg) and Acorus calamus rhizome (Vekhand) powder (4 g/kg) were found most effective in inhibiting egg laying even up to 6 month of storage after release of insect.
