A　vector-host　model　of　dengue　with　multiple　stages　and　independent　fluctuations　is　investigated　in　this　paper.　Firstly,　the　existence　and　uniqueness　of　the　positive　solution　are　shown　by　contradiction.　When　the　death　rates　of　aquatic　mosquitoes,　adult　mosquitoes,　and　human　beings　respectively　control　the　intensities　of　white　noises,　and　if　R-0(s)＞1,　then　the　persistence　in　the　mean　for　both　infective　mosquitoes　and　infective　human　beings　is　derived.　When　R-0(s)＞1　is　valid,　the　existence　of　stationary　distribution　is　derived　through　constructing　several　appropriate　Lyapunov　functions.　If　the　intensities　of　white　noises　are　controlled　and　phi＜0　is　valid,　then　the　extinction　for　both　infective　mosquitoes　and　infective　human　beings　is　obtained　by　applying　the　comparison　theorem　and　ergodic　theorem.　Further,　the　main　findings　are　verified　through　numerical　simulations　by　using　the　positive　preserving　truncated　Euler-Maruyama　method　(PPTEM).　Moreover,　several　numerical　simulations　on　the　infection　scale　of　dengue　in　Fuzhou　City　were　conducted　using　surveillance　data.　The　main　results　indicate　that　the　decrease　in　the　transfer　proportion　from　aquatic　mosquitoes　to　adult　mosquitoes　reduces　the　infection　scale　of　infective　human　beings　with　dengue　virus,　and　the　death　rates　of　aquatic　mosquitoes　and　adult　mosquitoes　affect　the　value　of　the　critical　threshold　R0s.　Further,　the　controls　of　the　death　rates　of　mosquitoes　are　the　effective　routes　by　the　decision-makers　of　the　Chinese　mainland　against　the　spread　of　dengue.
