Abstract: 

Granary weevil, Sitophilus granarius L.(Col;Curculionidae), is a cosmopolitan pest that feed on . cereal grains and cause heavy damages particularly wheat grains. The highest level of damage occurs during larval period when 1arvaefeed on kernel contents. Females only bore in grains to lay eggs. Larvae and pupal periods are completed inside the grains. Fourteen wheat varieties were used to determine sex ratio, developmental period and FI generation population under laboratory condition. Results obtained for both sexes were found identical. The highest number of weevil insect in seed kernel was counted for Arvand, Navid and M-70-12, while the lowest was for Falat. Golestan and Hirmand. The minimum developmental period were recorded for Arvand, Khazer and M-70-12, whereas maximum number observed for Hirmand, Ghods and Falat respectivety.
