Sitophilus zeamais is one of the main pests of stored corn. The objective of the present work was to identify the resistance of corn genotypes to the attack of different densities of S. zeamais. 15, 20, 25, 30 and 35 adult insects were used for infestation in samples of four maize genotypes: Nutricional Embrapa, Milho Roxo, 8 Carreiras and Palha Roxa. The number of emerged insects, grain mass loss, insect weight, longevity and sex ratio were evaluated. Maize Roxo and 8 Rows were the most resistant, as they had the lowest number of emerged insects and the lowest grain mass loss.
