Study of Impact of Edible and Non-Edible Oils on Grain Damage and Weight Loss of Green Gram in Storage Condition Infested with Pulse Beetle

Pulse beetle, Callosobruchuschinensis (Coleoptera Bruchidae) is a major stored grain pest of pulses in Odisha. Percent of grain damage and weight loss were studied with edible and non-edible oils treated green gram in storage condition at 45 days and 90 days after treatment during 2010-11 in the Post graduate Department of Zoology, Utkal University laboratory. The grain damage and weight loss were studied in different concentrations of oils i. e.1.00 ml, 1.25 ml and 1.50 ml per 100 g. of green gram seed of neem, karanja, sesamum, castor, palm, mustard, ground nut and sunflower. It was found that Neem and Karanja oil @ 1.5 ml/ 100 gram seed were effectively manage the grain damage and weight loss after 90 days of treatment of green gram in storage condition.
