A study was undertaken in the laboratory to estimate food consumption by larvae of Bruchidius incarnatus feeding on faba bean seed and to calculate a conversion factor based on the number of exit holes/seed. The emerged females were significantly heavier and consumed more food than the males. Weight loss caused by one larva/seed was significantly higher than that caused by two or three larvae/seed. Development time was not affected by multiple (more than one larva) infestation. The percentage apparent weight loss in faba bean seeds infested by B. incarnatus can be estimated by multiplying the percentage damaged seeds by 0.074, 0.114, or 0.163 for seeds with one, two, or three exit holes, respectively
