Abstract

Four experiments were conducted in the four governorates; Giza, Kalubia, Menofia and Fayoum to evaluate the fluctuations in the two-spotted spider mites, Tetranychus arabicus Attiah population on the four cucurbits, i.e. squash, cucumber, cantaloupe, and watermelon. The four cucurbit vegetables were exposed to mite infestation with diffemt degrees according to localities and cucurbit vegetables. In all governorates, cucumber and cantaloupe were the most favourable hosts as infested with the highest mite numbers, while watermelon and squash came after in this respect. As regards to locations, Giza and Kalubia had the highest infesta‌tions, while Fayoum had the lowest level.
