By　using　comparison　theorem　and　constructing　suitable　Lyapunov　functional,　we　study　the　following　periodic　Lotka-Volterra　model　with　M-predators　and　N-preys　by　＂pure-delay　type＂　[GRAPHICS]　A　set　of　easily　verifiable　sufficient　conditions　are　obtained　for　the　existence　and　global　attractivity　of　a　unique　positive　almost　periodic　solution　of　the　above　model,　which　improve　and　generalize　some　known　results.
