Abstract

The present study was conducted to estimate the susceptibility of 10 promising faba bean varieties to infestation by the cowpea weevil, Caflosobruchus maculatus F. Two pans of insects were provided with 25g of seeds from each variety and replicated three times. The number of eggs deposited per female, the percentage of emerged adults and the developmental period were recorded. Results showed obvious variation in the percentage of emerged adults, while the developmental perios did not very significantly. Seeds of N.A. 12 variety were most tolerant, while those of Giza-3 variety were most susceptible.
