Three different commercial species of legume seeds, Cowpea, Vigna unguiculata (Walp.), Faba beans, Vicia faba (L.), Soya beans, Glycine max (L.),and Five Phaseolus vulgaris (L.) varieties (White beans, Navy beans, Red (Kidney) beans, Pinto beans and Black beans) were tested for their susceptibility to Callosobruchus maculatus infestation. The present study aimes to assess the susceptibility of the local pulse seeds compared to the imported ones to C. maculatus infestation. Number of laid eggs, incubation period, hatchability percentage, number of emerged adults, adult longevity, mean developmental period, weight loss percentage damage, percentage, adult weight and susceptibility index were recorded as main parameters to evaluate susceptibility of the tested legume beans to C. maculatus infestation. The highest mean number of eggs was laid on marine beans (20.5 per seed), while Soya beans have received the lowest mean number of eggs (5.25 per seed). Mean incubation period was not significantly differed between all tested legume seeds. The percentage of hatchability between the eight tested legume seeds were significantly differed. The highest percentage of egg hatchability was obtained in cowpea seeds 99.01%, while the navy bean seeds have the lowest percentage of egg hatchability (96.09%). Zero adult emergence in red, navy, white, black and pinto bean seeds this due to the presence of vicine in these seeds which act as a larval inhibitor and prevent the larva to complete its duration. The mean number of emerged adults was 42.25, 35.75 and 9.75 in cowpea, faba and soya bean seeds, respectively. Results indicated that cowpea was the most susceptible legume seeds to C. maculatus with the highest value of Susceptible Index (SI) (6.188) followed by faba (5.640) and soya beans was moderately resistant to C. maculatus (3.84). The same trend was recorded regarding to percentage of weight loss, percentage of damage and adult weight. Red, navy, white, black and pinto beans were resistant to C. maculatus infestation with zero value of Susceptible Index (SI). The resistant of these legume seeds to C. maculatus infestation probably due to the texture of seed coat, and their hardness or presence of other toxic compounds in these seeds.
