Pseudo almost periodic solution of Nicholson’s blowflies model with mixed delays

This paper presents a new generalized Nicholson’s blowflies model with a linear harvesting term and mixed delays. The main purpose of this paper is to study the existence and the attractivity of the pseudo almost periodic solutions, which are more general and complicated than periodic and almost periodic solutions. Under suitable assumptions, and by using fixed point theorem, sufficient conditions are given to study the pseudo almost periodic solution for the considered model. Moreover, an illustrative example is given to demonstrate the effectiveness of the obtained results.
