Abstract
Single—species populations of flour beetles, Tribolium confusum and T. castaneum, were experimentally manipulated to demonstrate that both predation by adults on pupae and predation by larvae on eggs are effective mechanisms for regulating the abundance of adult beetles. It was shown that predation by adults on pupae is the more effective of the two mechanisms, since experimental interference with the first kind of predation produces a larger increase in adult populations than does interference with the second kind. The same generalization holds for both species.
