โœฆ Synopsis

This paper is concerned with a non-autonomous stage-structured predator-prey model with harvesting terms. By means of the coincidence degree theory, we establish the existence of at least eight positive periodic solutions for the system under consideration. An example is given to illustrate the effectiveness of our results.

By using Mawhin's continuation theorem of coincidence degree theory, we derive a sufficient condition for the existence of at least one positive periodic solution of a generalized prey-predator model with harvesting term.
