| Abstract: | In this paper the existence of positive periodic solutions for two-species systems of neutral differential equations with infinite delays is investigated. Some sufficient conditions are obtained by means of the theory of coincidence degree. |

| Keywords: | infinite distributed delay neutral coincidence degree positive periodic solutions |
