摘　　要：芬兰钝绥螨的雌成螨对针叶小爪螨幼螨、若螨和成螨的捕食功能反应均属HollingⅡ型。针叶小爪螨的螨态、芬兰钝绥螨的饥饿程度、生境大小等因素均可引起功能反应参数的变化。芬兰钝绥螨的雌成螨喜食针叶小爪螨的幼螨和若螨 。The curves of the functional response of Amblyseius finlandius(Oudemans)to the nymphs and female adults of O1igonychus ununguis(Jacobi)were shown as Holling Ⅱ.Several factors, such as the age of O1igonychus ununguis, the length of Amblyseius finlandius being starvated and the size of habitat,could lead to the change of the parameters of the functional response. The female adults of Amblyseius finlandius like predating the nymphs of O1igonychus ununuis, while not very like the female aduits.
