Abstract
In this paper, we establish the theory of basic reproduction ratio \(R_0\) for a large class of time-delayed compartmental population models in a periodic environment. It is proved that \(R_0\) serves as a threshold value for the stability of the zero solution of the associated periodic linear systems. As an illustrative example, we also apply the developed theory to a periodic SEIR model with an incubation period and obtain a threshold result on its global dynamics in terms of \(R_0\).
