• Nicholson-type delay system
• positive periodic solution
• coincidence degree
• non-linear density-dependent mortality term

This paper is concerned with the periodic solutions for a class of new Nicholson-type delay system 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 is employed to illustrate the main results.
