Abstract

Untreated pigeonpea grains (Cajanus cajan L.) of UPAS-120 variety and dhal prepared from untreated pigeonpea grains, NaHCO3 treated and oil-treated pigeonpea grains were subjected to storage studies for eight months (April to November) under ambient storage conditions. Three types of packaging materials i.e. polythene bags, polylined bags and jute bags were used for storing the grain and dhal samples at 9% and 12% initial moisture levels. Effect of fumigation with ethylene-di-bromide was also investigated on infestation. The storage study concluded that pigeonpea grain stored in polythene and polylined bags was more susceptible to infestation. Pulse beetles infested pigeonpea grains while in dhal samples rice moth and weevils were the main infesting insects. For dhal samples, polythene bags had the lower level of infestation compared to po1yhned and jute bags NaHCO3 treatment and fumigation with ethylene-di-bromide coukl reduce the level of infestation upto some extent.
