Abstract
The cannibalistic tendencies" of 8 strains of flour beetles, 4 of Tribolium castaneum and 4 of T. confusum, are described and compared. For all of the strains the predatory consumption of eggs and pupae by larvae and adults is important, both as a source of mortality and as a population regulatory mechanism. The intensity of cannibalism depends upon species and strain of predator, species of prey, and the stage of development of predator and prey. In some cases the predatory preferences are homospecific; in others, heterospecific.This publication has 8 references indexed in Scilit:
