摘　　要：应用二次正交旋转组合的设计方法，研究了在不同的天敌密度，害虫密度，温度和光照时间的动态系统中，真水狼蛛对稻田主要害虫褐飞虱的捕食作用，得出其控制作用的数学模型为ｙ＝２７．４０８７＋３．１６６７Ｘ１＋６．８３３３Ｘ２－１．６６７Ｘ３＋０．５０００Ｘ４－０．４２５８Ｘ＾２１－０．９２５８Ｘ＾２２－３．１７５８Ｘ＾２３＋０．２５００ｘ１ｘ２＋１．５０００ｘ３ｘ４通过模型的主效应分析。The positive rotation design quadratic regression was adopted in foraging behavior of Pirata Piraticus on Nilaparavata lugens in the system of different predator density,different pest density, different temperature and different illumination time. A mathmatic model which was about the foraging behavior of Pirata piraticus on ilaparvata lugens was obtained : y = 27. 4087 + 3. 1667x1 + 6. 8333.x2-1. 1667x3 + 0. 5000.x4-0. 4258x12-0. 9258.x22-3. 1758x32 + 2. 2500x1x2 + 0. 5000x1x3- 1. 5000x3x4. The analysis of its principal effect and mutual effect showed that different environmental factors have influenced on the prey of predator. The daily amount preys was obtained as well that was 19. 372.
