This study was conducted in the Department of Plant Protection at the Faculty of Agriculture to investigate the effect of primary density and breeding periods on Intraspecific competition between individuals of the same speceies the saw–toothed grain beetle, Oryzaephilus surinamensis. The results showed that competition increased when the primary number was large. The results showed that the effect of breeding periods on on Intraspecific competition between individual of the tested insect started with the beginning of the experiment and continued until the end of the experiment, and it was also noted that the on Intraspecific competition between its members was high when the primary numerical density was few where the number of insects increased with increasing periods of breeding.
