摘　　要：研究了三突花蛛和星豹蛛对涝渍菜田短额负蝗的捕食能力、寻找效应和种内干扰。结果表明,三突花蛛和星豹蛛对短额负蝗的捕食能力可拟合为HollingⅡ型;三突花蛛的寻找效应为Sm=0.033 6/(1+0.005 4N),星豹蛛为Sp=0.287 6/(1+0.025 3N);三突花蛛和星豹蛛种内干扰反应模型分别为Em=0.026 2·P-0.2791,Ep=0.407 2·P-1.1527;分摊竞争强度I分别为Im=0.504 7logP+0.018 8,Ip=0.884 8logP+0.035 6。Predation,searching rate and intraspecific interference of Misumenops tricuspidatus and Pardosa astrigera to Atractornorpha sinensis from waterlogging vegetable fileds were studied. Functional response of Misumenops tricuspidatus and Pardosa astrigera to Atractornorpha sinensis were fitted well with Holling＇s type Ⅱ. Searching rate of Misumenops tricuspidatus was Sm=0.033 6/（1＋0.005 4N）,of Pardosa astrigera was Sp=0.287 6/（1＋0.025 3 N）. The intraspecific interference moddle of Misumenops tricuspidatus and Pardosa astrigera were Em=0.026 2·P^-0.2791 and Ep=0.407 2·P^-1.1527 respectively, The scrambling competition （Ⅰ） were Im=0.504 7logP＋0.018 8 and Ip=0.884 8logP＋0.035 6 respectively.
