In this paper we studied the dynamics of one ammensal and two mutualistic species. A distributed time lag is
induced in the interaction of ammensal and the first mutual species. Local and global stability analysis is
discussed at co-existing state. Numerical simulation with different delay kernel strengths are illustrated and
proved that delay kernels are plays a significant role in the improvement of two mutual species populations.
