Abstract
This paper considers a delay nonautonomous Lotka–Volterra type multispecies competitive system with harvesting terms. The model has the intraspecific competition terms defined by functions which depend on population densities. An existence theorem of 2n2n positive periodic solutions is established by using the coincidence degree theory. An example is given to illustrate the effectiveness of our result.
