In　this　paper,　we　propose　a　discrete　Nicholson’s　blowflies　model　with　feedback　control.　Sufficient　conditions　are　obtained　for　the　permanence.　By　means　of　an　almost　periodic　functional　hull　theory,　we　show　that　the　almost　periodic　system　has　a　uniqueness　of　globally　attractive　almost　periodic　solution.　Moreover,　a　suitable　example　and　its　numerical　simulation　are　given　to　illustrate　the　feasibility　of　the　main　results.　©　2016,　Chen　et　al.
