Abstract
The present investigation is carried out to evaluate the relative susceptibility of eight legume varieties to the infestation with the cowpea beetle, Callosobruchus maculatus (F.). The loss in grain weight and the percentage of infested grains were determined in choice and force infestation tests. The obtained results, either in the choice or non-choice infestation tests, indicated that, none of the tested varieties were completely resistant against the attack by the pest but their susceptibility to the infestation varied considerably. Regardless of legume variety, cowpea varieties showed high susceptibility to the infestation by C. maculatus. While, faba bean and lentil varieties were the least ones and chickpea varieties were found to be inbetween.
