Abstract: α-amylase inhibitor, a seed storage protein, is quantified in different wild pulses. These wild pulses when tested for their relative resistance to the bruchid, C. maculatus, showed that most of the developmental parameters of the pest are significantly affected. The wild variety of the species, Lablab purpureus with brown seed coat which contains a higher amount of the inhibitor was selected for purification and characterisation. α-amylase inhibitor purified from this variety has a molecular weight of 65 kDa in non-denaturing electrophoretic gel which resolved into three polypeptides of 14, 17 and 20 kDas respectively in denaturing electrof1horetic gel.
