摘要: 应用特征根回归法建立了拟水狼蛛(Piratasubpiraticus)、食虫瘤胸蛛(Oedothoraxinsecticeps)、粽管巢蛛(Clubionajaponicola)和菱头跳蛛(Bianorhotingchiehi)4种蜘蛛与褐飞虱(Nilaparvatalugens)共存系统捕食量的特征根回归模型:y=6.6600+6.3399(-0.0138X1+0.0895X2+0.0078X3-0.1067X4+0.6742X5).以此模型对蜘蛛捕食量进行了模拟或预测分析,并同LS回归方法进行了比较.结果表明,特征根回归法可用于蜘蛛对褐飞虱捕食量的定量分析,比LS回归方法提高精度10%.

Abstract: Alatent root regression model was constructed for analyzing the predation quantity in a coexistence system of four spiders (Pirata subpiraticus,Oedothorax insecticeps,Clubiona japonicola, and Bianor hotingchiehi) with brown planthopper (Nilaparvata lugens). The predation quantity of the spiders in a multi species coexistence system could be predicted by y= 6.6600 +6.3399(-0.0138X1* +0.0895X2*+0.0078 X3* -0.1067X4* +0.6742X5*). The result showed that compared to LSregression, the accuracy of predation quantity predicted by the model increased by 10%.
