Abstract
A national survey shows that the merchant grain beetle, Oryzaephilus mercator Fauvel, has been present in Canada since at least 1925 and that it has become firmly established as a household pest of processed cereal products preferably of high oil content, but has not been reported from stored grain. A related species, the saw-toothed grain beetle, Oryzaephilus surinamensis (L.), infests both stored grain and processed cereal products. Illustrations are provided to show the morphological characters by which the two species may be recognized and separated.Keywords
