The purpose of this article is to investigate the existence of almost periodic solutions of a system of almost periodic Lotka-Volterra difference equations which are a prey-predator system and a competitive system , by using certain stability properties, which are referred to as -weakly uniformly asymptotic stable in hull and -totally stable.
