This paper deals with a modified nonautonomous version of the classical predator-prey model including a Hassell-Varley type functional response and two time-dependent delays.NEWLINENEWLINEBy applying the coincidence degree theorem, sufficient conditions for existence of positive periodic solutions are established.NEWLINENEWLINEThe paper ends with some numerical simulations to illustrate the theoretical results.
