摘　　要：应用二次正交旋转组合设计方法建立贺氏菱头蛛Bianorhotingchiehi和食虫沟瘤蛛Ummeliatainsecticeps对稻纵卷叶螟Cnaphalocrocismedinalis和稻褐飞虱Nilaparvatalugens捕食作用的数学模型分别为:Y′cm=3.9984-0.2083x1+0.7917x2+2.1250x3+0.2917x4+0.5625x1x2-0.1875x1x3+0.1875x1x4+0.8125x2x3+0.1875x2x4+0.1875x3x4-0.4703x21+0.0305x22+0.0305x23-0.0940x24;Y′nl=6.2832+0.2917x1+0.5417x2-0.1250x3+3.625x4-0.0625x1x2+0.5625x1x3+0.4375x1x4-0.4375x2x3+0.4375x2x4-0.4375x3x4-0.2299x21-0.1047x22+0.0250x23+0.2709x24。结果表明,食虫沟瘤蛛是稻纵卷叶螟和稻褐飞虱的更为重要的捕食性天敌。贺氏菱头蛛对各种干扰作用表现更为敏感。Mathematical models of predation of Bianor hotingchiehi and Ummeliata insecticeps on Cnaphalocrocis medinalis and Nilaparvata lugens established with quadratic rotation-orthogonal combination design were： Y＇cm=3.9984-0.2083x1＋0.7917x2＋2.1250x3＋0.2917x4＋0.5625x1x2-0.1875x1x3＋0.1875x1x4＋0.8125x2x3＋0.1875x2x4＋0.1875x3x4-0.4703x1^2＋0.0305x2^2＋0.0305x3^2-0.0940x4^2;Ynl＇=6.2832＋0.2917x1＋0.5417x2-0.1250x3＋3.625x4-0.0625x1x2＋0.5625x1x3＋0.4375x1x4-0.4375x2x3＋0.4375x2x4-0.4375x3x4-0.2299x3^2-0.1047x2^2＋0.0250x3^2＋0.2709x4^2 Results showed that U. insecticeps was the more effective natural enemy to both C.medinalis and N. lugens. B. hotingchiehi was more sensitive to all kinds of interferences.
