Random sampling methods were used in selecting traders in the markets for the survey. Samples of 1kg of maize, Millet, Sorghum and rice were taken from the stock with the traders for analysis and insect infestation determination. Insect species identified with the grains and their relative abundance in percentages are; Tribolium castaneum Herbst 30.9%, Sitophilus spp 27.4%, Rhizopertha dominica (Fab) 15.2%, Trogoderma granarium (Everts) 11.9% and Cryptolestes spp (Stephens) 14.7%. The result also indicates that T. castaneum and Sitophilus spp were more prevalent. The species preference to different grain types in the order T. castaneum was dominant in maize and Millet; Sitophilus species were dominant in Maize and sorghum, and Rhizopertha dominica being the dominant species in Rice.1 aChimoya, I., A.1 aAbdullahi, Gambo  uhttps://weevil.myspecies.info/species-compositions-and-relative-abundance-insect-pest-associated-some-stored-cereal-grains-selecte
