Abstract: A competitive system was studied that has a discrete delay stage-structure and cannibalism, where one of the species has two stages, an immature stage and a mature stage. By means of the continuous theorem of coincidence degree theory,a sufficient condition is obtained for the existence of a positive periodic solution of the system when cannibalism occurs.
