Abstract: This paper is concerned with the periodic solutions for a class of Nicholson‐type delay systems with nonlinear density‐dependent mortality terms. By using coincidence degree theory, some criteria are obtained to guarantee the existence of positive periodic solutions of the model. Moreover, an example and a numerical simulation are given to illustrate our main results.
