The influences of these different vegetable plant hosts on the biological response of Brevicoryne brassicae (L) and Aphis gossypii (Glover) were studied. The results obtained for B. brassicae (L) indicated that the lowest number of individuals produced per female was 11.50 when insects were fed on radich; this number was increased to 22.00 and 70.25 individuals when insects were fed on Garden rocket and cabbage, respectively. In fact, this insect infested most vegetable crops in state of Qatar as cauliflower, cabbage, Radich, Garden rocket and certain ornamental causing considerable damage to all economic crops. In case A. gossgpii (Glover), squash was proved to represent the most suitable host production, followed in a descending order by cucumber and snake cucumber. This insect insfested all vegetable and other crops in State of Qatar and its infestation was higher on certain vegetable plants, of these. Tomoto, Egyplant, Carrot, Cantaloupe, water melon, cucumber, squash, pepper, Onion, Lettuce, pumpkin, other vegetable, most of fruit trees and certain ornamental plants.
