Abstract
    Choice and non-choice tests were carried out to determine the influence of certain maize varieties on the rice weevil, Sitophilus oryzae (L) infestation under laboratory conditions. Regarding to non-choice tests on different maize varieties, data revealed that, Tri-Hybrid 353 yellow variety was the highest weight after damage. while Tri-Hybrid 311 white variety was the highest percentage weight loss and lowest weight after damage. In addition, Tri-Hybrid 353 yellow variety was the longest total developmental period and lowest number of F1 while Tri-Hybrid 311 white variety was the shorter total developmental period and highest number of F1 progeny. In respect to free choice on different maize varieties, data revealed that, Tri-Hybrid 353 yellow variety was the highest weight after damage, while Tri-Hybrid 311 white variety was the highest percentage weight loss and lowest weight after damage. On the other hand, the index of susceptibility (IS) among the varieties tested showed that Tri-Hybrid 311 white was moderately susceptible for different maize grains varieties and other varieties were moderately resistant.
