Abstract
Adult males of the flour beetles Tribolium confusum and T. castaneum were found to be several times more voracious than were females as cannibals of pupae. This is exactly the reverse of the sex differences reported earlier with regard to egg—eating; as egg cannibals, females excel males by 7 to 19 times. This is a remarkable division of labor between the two sexes with respect to cannibalistic self—regulation of numbers.Keywords
