研究了拟长毛钝绥螨(Amblyseius pseudolongispinosus)对朱砂叶螨(Tetranychus cinnabarinus)的捕食作用。结果表明,拟长毛钝绥螨若螨和雌成螨对朱砂叶螨各螨态的捕食功能反应,即捕食量与猎物密度之间呈逆密度制约关系,功能反应曲线属HollingⅡ型;对猎物卵和幼若螨的控制能力最强;猎物的螨态、生境大小等因素均可引起拟长毛钝绥螨功能反应参数的变化;拟长毛钝绥螨的自身密度对功能反应存在密度制约作用;拟长毛钝绥螨对朱砂叶螨卵和幼若螨是嗜食的,对成螨是非嗜食的。
The predation effect of Amblyseius pseudolongispinosus on Tetranychus cinnabarinus was studied. The results showed that the predatory functional response of mites and mites to the mites of Tetranychus cinnabarinus, that is, the relationship between the predation amount and the density of the prey, showed an inverse density relationship and the functional response curve was Holling Ⅱ. Eggs and young nymphs have the strongest control ability. The mite state and habitat size of prey can cause the change of functional parameters of A. longiflorus. The self-density of A. militaris has a density control on the functional response Effect; Propagated long-winged amblyseous mites on the vermilion mite eggs and young nymphs are food-eaten, on the mites are non-addicted.
