| 摘 要： | 芬兰真绥螨对山楂叶螨卵、幼若螨的功能反应为H0llingⅡ型.其功能反应方程(RH80±10％,T=25士1℃)分别为Na=N/(3.6133+0.0141N)和Na=N/(2.2165+O.2527N)。最大日捕食量分别是:71.11粒和4头.在山楂叶螨各(土艹两)态中,对卵有明显的正喜好,其次是幼若螨。对雌成螨则表现负喜好。在山撞叶螨和苹果全爪螨雌成螨间,对苹果全爪螨表现明显的正喜好。

| Abstract: | Laboratory experiments were performed to determine the functional responses of Euseius finlandicus to Tetranychus viennensis. The curves of functional responses to the eggs and nymphs of T. viennensis were shown as holling Ⅱ correspondly, and its equation of functional responses were respectivly: Na=N/(3.6133+0.0141N), Na=N/2.2165+0.2527N). The day maximum predation of each predator was 71.11 eggs and 4 nymphs of T. viennensis. E. finlandicus had a like to predate the eggs of T. viennensis, then the nymph. The female adults were dislike of food. Between the female adults of T. viennensis and P. ulmi, the former liked to predate the latter. |
