Abstract

The vulnerability of the tested varieties of cowpea and faba bean seeds to post-harvest infestation by Collosobnichus maculatus (F.) revealed that Karim 7 was the least susceptible cowpea variety while Kafr El-Sheikh-1 was the most susceptible. For faba bean varieties, Giza 429 was the most infested and Giza 674 proved to be the least susceptible. These results were based on duration of C. macu/atus(F.) reared on these varieties, survival rates, rate of emerged beetles and female fecundity.
