Abstract
The cultivars of some grapevines (Vitis vinifera L.) varieties, King Robi, Black Rose, Flame Seedless, Thompson Seedless and Bez El-Anza were cultivated at Noubaria Province, El-Baheira Governorate, during the season 2005. These varieties were tested under laboratory conditions to study their relative  susceptibility to the infestation of Tetranychus urticae Koch infestation at 25 + 2 ºC and 70 + 5 % R.H. . King Robi Varity was the most susceptible Varity while Bez El-ElAnza.varity was the less susceptible one. On the other hand, Black Rose, Flame Seedless and Thompson Seedless have moderate suscebtiplity.The highest number of eggs was noticed on King Robe varity young leaves (18.35 eggs).
