This　paper　discusses　a　discrete　Lotka-Volterra　competition　system　with　feedback　controls.　We　first　obtain　the　persistence　of　the　system.　Assuming　that　the　coefficients　in　the　system　are　periodic,　we　obtain　the　existence　of　a　periodic　solution.　Moreover,　under　some　additional　conditions,　this　periodic　solution　is　globally　stable.　(c)　2006　Elsevier　Inc.　All　rights　reserved.
