Abstract:
Four storage structures viz., cloth bag, plastic jar, jute bag and bamboo basket were evaluated for their effect on the incidence of pulse beetle, Callosobruchus chinensis infesting ricebean seeds in storage. The experiment was conducted in a Completely Randomized Design with 5 replications. The storage structures were evaluated based on per cent infestation and weight loss up to 6 months of storage. The infestation and weight loss up to 6 months of storage ranged from 2.48 to 90.54% and 0.29 to 25.08%, respectively. The per cent weight loss increased significantly with the increase in infestation. The most effective result with the least per cent infestation and weight loss after 6 months of storage was found in plastic jar with 76.65 and 16.20%, respectively. Cloth bag was the least effective with 90.54% infestation and 25.08% weight loss. The effectiveness of the storage structure was found in the order: plastic jar > bamboo basket > jute bag > cloth bag.
