摘要
应用二次正交旋转组合设计方法建立3种天敌、2种害虫共存情况下白背飞虱被捕食数量与5个因素相互关系的数学模型。结果表明,3种天敌对白背飞虱被捕食量影响的大小排序为拟水狼蛛>青翅蚁形隐虫>食虫沟瘤蛛,食虫沟瘤蛛与拟水狼蛛、拟水狼蛛与青翅蚁形隐翅虫有负交互作用。
Under the coexistence of 3 natural enemies and 2 pests, the mathematical model of interrelationships between the number of SogateIIa furcifera preyed upon and 5 factors was established with quadratic rotationorthogonal combination design. Results showed that the order of effectiveness of predators to the number of S.furcifera preyed upon was Pirata subpiratica 〉 Paederus fuscipes 〉 Ummeliata insecticeps, there existed negative interactions between U. insecticeps and Pirata subpiratica, Pirata subpiratica and Paederus fuscipes.
