**Relative Susceptibility of Some Sorghum Varieties to the Rice Weevil, Sitophilus oryzae L. (Coleoptera: Curculionidae)**

The aim of the present study is to find alternative and safe ways for storing grains. A total of 36 sorghum varieties were screened for their relative susceptibility to S. oryzae. Varieties BES, ICSV111, ICSV247, ICSV1079BF and ICSH89009NG had a low index of susceptibility and were regarded as resistant. Varieties SINGE-2, SK5912, ICSV902NG, KSV 8, 18395 and ICSV 210 had a high index of susceptibility and were regarded as highly susceptible. The resistant varieties had low number of F₁ progeny emerging from them, had low percentage damage and weight loss. The susceptible varieties had high number of F₁ progeny, high percentage damage and weight loss. Grain hardness was found to be the overall factor responsible for resistance to S. oryzae.
