Agriculture University, Peshawar to test maize cultivars against maize aphid from July to October, 1990. Varietal trial showed that aphid on different maize cultivars ranged from 0 to 200 aphids/plant with a mean range of 3.42 to 42 aphids/plant during the season. Hari showed a maximum aphid density (42.17 per plant) followed by Sarhad white (29.99), Ihsan (27.24), Dehqan (23.36), Azam (21.42), Shaheen (14.16), EV-I (10.93). Gohar showed the least density (3.42). Gohar and Hari both were statistically different from all the other cultivars. Ihsan showed statistical similarity to Sarhad White, Dehqan and Azam.
