摘要：应用二次正交旋转组合设计方法建立贺氏菱头蛛Bianor hotingchiehi和食虫沟瘤蛛Ummeliata insecticeps对稻纵卷叶螟Cnaphalocrocis medinalis和稻褐飞虱Nilaparvata lugens捕食作用的数学模型分别为:Y'cm=3.9984-0.2083 x1+0.7917 x2+2.1250 x3+0.2917 x4+0.5625 x1x2-0.1875 x1x3+0.1875 x1x4+0.8125 x2x3+0.1875 x2x4+0.1875 x3x4-0.4703 x21+0.0305 x22+0.0305 x23-0.0940 x24;Y'nl=6.2832+0.2917 x1+0.5417 x2-0.1250 x3+3.625 x4-0.0625 x1x2+0.5625 x1x3+0.4375 x1x4-0.4375 x2x3+0.4375 x2x4-0.4375 x3x4-0.2299 x21-0.1047 x22+0.0250 x23+0.2709 x24 .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.
