摘　　要：应用二次旋转组合设计方法建立拟水狼蛛和食虫沟瘤蛛雌蛛对稻褐飞虱捕食作用模型。结果表明,食虫沟瘤蛛雌蛛是稻褐飞虱更为重要的捕食性天敌。当蜘蛛密度较高时,拟水狼蛛常常捕杀食虫沟瘤蛛,导致稻褐飞虱被捕食量的下降。The mathematical model of predation of Pirata subpiraticus and female Ummeliata insecticeps on Nilaparvata lugens established with quadratic rotation combination design was： Ynl＇ =10.310 5 ＋0. 146 4x1 ＋ 1. 394 5x2 ＋7. 125 6x3 -0. 7500x1x2 -0. 2500x1x3 ＋0. 7500x2x3 ＋ 0. 926 6x1^2 ＋ 1. 280 1x2^2 ＋0. 926 6x3^2. The analysis results showed that female O. insecticeps was the more effective predator to N. lugens. There was interference between P. subpiraticus or between P. subpiraticus and O. insecticeps.
