Abstract
Laboratory studies of interaction of the red flour beetle, Tribolium castaneum (Herbst), and the cigarette beetle, Lasioderma serricorne (F.), revealed that numbers of the latter were reduced, at all densities, by predation by the red flour beetle. Numbers of red flour beetles were increased when immatures of the cigarette beetle were supplied as prey. Adult and late-instar red flour beetles generally killed more immobile prey (eggs and pupae) than mobile prey (larvae). The number of prey killed per predator increased as prey density and duration of exposure to the predator increased.This publication has 2 references indexed in Scilit:
