In this study of lentil infestation by three bruchid species, lentil seeds were most infested by Bruchidius incarnatus, followed by Callosobruchus chinensis, and then by C. maculatus. The three bruchids reduced the seed weight and also inhibited seed germination following the same ranking of species. Increased infestation was accompanied by increased moisture in infested seeds. The increased moisture content had reached similar levels for the three species by the end of the experiment. As far as the bruchids' effect on the chemical constituents of lentil seeds, B. incarnatus caused the greatest losses in carbohydrates and fatty acids, followed by C. chinensis, while C. maculatus caused the lowest losses. C. chinensis produced the greatest reduction in protein content, followed by C. maculatus and B. incarnatus. The two Callosobruchus species produced a similar reduction in free amino acid content, while B. incarnatus produced the least such reduction
