| Abstract: | this paper studies a mixed model with a type of Beddington-DeAngelis functional response.The second group with sexual favoritism to the first group.The conditions of globally asymptotic stability is obtained.A set of sufficient conditions on the existence and uniqueness of almost periodic solutions of the systems is obtained. |
