摘要: 本文研究三突花蛛对小菜蛾幼虫的捕食功能反应及干扰因素对捕食作用的影响。结果表明,三突花蛛对小菜蛾幼虫的捕食效应属HollingⅡ型反应,捕食作用率随捕食者-猎物比率上升而下降,雌蛛的捕食效应强于雄蛛。

Abstract: Functional predacious response of Misumenop tricspidatus to Plutella xylostella larvae and effect of interferential factors on predacity were studied under the laboratory text. The results indicated that the type of functional response of the spiders referred as to Holling's Ⅱ and the predacious efficiency decreased as the increase of predator-prey ratio. The female spiders killed more larvae than the male ones. There was no significant difference between experimental data and theoretical data by X2-test.

Key words: Misumenop tricspidatus, Plutella xylostella, predacious model, predacious interference response
