In this study, the two-dimensional predator-prey system with Beddington–DeAngelis type functional response with impulses is considered in a periodic environment. For this special case, necessary and sufficient conditions are found for the considered system when it has at least one $w$-periodic solution. This result is mainly based on the continuation theorem in the coincidence degree theory and to get the globally attractive $w$-periodic solution of the given system, an inequality is given as the necessary and sufficient condition by using the analytic structure of the system.
