Susceptibility of small bulks of rapeseeds and sunflower seeds to 3 species of stored-product insects was determined by infesting the oilseed singly and collectively in an unheated granary during the summers of 1972 and 1973 in Manitoba. During the study, insects were never exposed to temperatures higher than 25°C for more than 2 months. Oryzaephilus mercator (Fauvel) and Tribolium castaneum (Herbst) reproduced well on both seeds. Many adults and larvae were recorded when single infestations of these insects were in the sunflower bulks. Cryptolestes ferrugineus (Stephens) did not reproduce or survive on rapeseed but maintained a low adult population on sunflower.
