Several maize varieties with high-yield potential have recently been created; however, their resistance to storage pests is unknown. This study compares the resistance ability to Sitophilus zeamais of four open-pollinated varieties (OPVs) and thirteen hybrid maize varieties using Dobie's susceptibility index (SI). The genotypes were tested in a completely randomized design with three replications at a temperature of 28°C and a humidity of 65 to 70%. A resistant OP maize variety (Melkassa 6Q) had SI of less than 3.5 (3.43). OPVs evaluated (Gambela, Gibe 2, and Gibe 3) had SI of 4.60, 5.32, and 6.77, respectively, while most hybrid varieties had SI of 3.82,
