A study was carried out on the resistance of four cereal crops (barley, wheat, sorghum and maize) to cereal aphid species at Assiut, Egypt. The results obtained show that there were significant differences among the cultivars tested. Among the five barley cultivars; Giza 132 was highly susceptible while the remaining cultivars were moderately resistant. Among the five wheat varieties; Gemiza 11 and Giza 168 were highly susceptible, followed by cultivars Sids 12 and Shandauel 1. Sids 1 showed moderate resistance. Among the five sorghum cultivars; Dorado was highly susceptible and Sphinx was susceptible. The aphid population declined significantly on Giza 15 and Hourse that were relatively (slightly or low) resistant (RR). The lowest aphid number recorded on the local (Baldi) variety showed moderate resistance. Among the five maize cultivars; the local (Baldi) cultivar was highly susceptible, followed by Unico 6, Triple 310 and Unico 131 that showed relatively resistance. The remaining cultivar, Unico 81, was infested with a low number of aphids and showed moderate resistance. The influence of aphid infestation on grain yield losses of wheat and barley cultivars were also evaluated.
