Abstract

The susceptibility of commonly cultivated 3 squash cultivars (Eskandarani, zucchini and Arlika) and 3 cucumber cultivars ( Alegi, sliberti and Sweet Kransh) to infestation with Bemisia tabacia (Genn.) (Homoptera : Aleyrodidae) was evaluated in Beni-Suef Governorate dur­ing Nili plantations 199680 997 The differences between the mean numbers of adults/leaf and juveniles (egg, larvae and pupae) / square inch on squash and cucumber cultivars were significant, during both seasons. Squash hybrids of (Zucchini and Arlika) were the least susceptible, while Eskandarani varie­ty was more susceptible. For cucumber cultivars, Sliberti hybrid was the least susceptible followed by Sweet Kransh than Alegi was being the most susceptible.
