Kaffir corn ( Sorghum vulgare ), which is easily susceptible to damage by insects during storage, was subjected to infestation by Calandra oryzae L. (weevils) and the changes brought about in the grain have been studied. The results show that weevils cause a heavy loss in the weight of the grain. The extent of unhygienic conditions brought about in the grain by the presence of insect excreta and body fragments has been assessed. The uric acid (an important constituent of insect excreta) content of the grain was found to increase with the progress of infestation. An increase in the kernel damage and fat acidity and a decrease in the thiamine content were also observed.
