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。
Functional predacious response of Aisumenop tricspidatus to PlutellaXylostella larvae and effect of interferential factors on predacity were studiedunder the laboratory text. The results indicated that the type of functional responseof the spiders referred as to Holling's Ⅱ and the predacious efficiency decreasedas the increase of predator-prey ratio. The female spiders killed more larvae thanthe male ones. There was no significant difference between experimental data andtheoretical data by X'-test.
