Much　of　the　existing　stage-structured　consumer　models　ignore　the　permanence.　I　it　this　paper.　we　consider　the　permanence　for　a　series　of　staged-structured　consumer-resource　models　with　the　function　response　of　so-called　＂prey-dependence＂　(resource　dependence)　type.　We　show　that　the　systems　are　permanent,　if　and　only　if　the　adult　consumer＇s　recruitment　rate　at　the　peak　of　resource　abundance　is　more　than　its　death　rate.　Our　results　indicate　that　the　large　consumer＇s　maturation　time　delay　will　directly　lead　to　its　extinction.　Furthermore,　our　arguments　for　the　main　results　give　a　light　for　permanence　in　the　general　stage-structured　consumer-resource　Systems.　(c)　2006　Elsevier　B.V.　All　rights　reserved.
