Eight cultivars of the faba bean, Vicia faba L, were chosen for field trials to study their effect on populations of the black bean aphid, Aphis fabae Scopoli (Homoptera: Aphididae) in Al-Jubeiha in Jordan. The tested cultivars were; B.L.L. 2004, B.S.2004, B.M.2004, Jordan 2004, I.L.B. 1814, Giza 4/2000, I.L.B. 1266 and Giza429/04. The studied parameters were: number of aphid colonies, number of infested plants, percentage of infested plants and number of aphids. The cultivar B.L.L.2004 sustained high population levels of A. fabae, whereas, lower population levels were noted in cultivar Giza4/2000. The other tested cultivars proved to sustain somewhat lower populations.
