New results on positive pseudo-almost periodic solutions for a delayed Nicholson's blowflies model

This paper is concerned with a non-autonomous Nicholson's blowflies model with an oscillating death rate. Under proper conditions, we employ a novel argument to establish a criterion on the global exponential stability of positive pseudo-almost periodic solution, which improves and extends some known relevant results. Moreover, an example along with its numerical simulations is presented to demonstrate the validity of the proposed result.
