RESUMO
A laboratory study of wheat stored at two different levels of moisture content with and without presence of Sitophilus zeamais Motschulsky was performed. Flexible PVC and polythene films as seals were used in order to examine their effectiveness to maintain the wheat quality by comparing changes in moisture content, germination and weight loss. The PVC film showed a high water vapor permeability and it behaved as the permeable muslin control, keeping the grain quality in all tested conditions. The polythene film showed a low water vapor permeability and it allowed the insects development. It seems that plastic films may be useful in grain stores bearing in mind their properties, adequate sealing and protecting them from insect damage, besides they should be selected according to environmental conditions
