Using the method developed by the author in [4-5], we investigate in this paper the existence of a strictly positive (componentwise) periodic solution of the following nonlinear, nonconvolution,volterra integerodifferential equation with infinite delay,which can describe an n-species ecologic system. The results of [1-3] are improved and extended.
