| 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 3.1667 x_1 6.8333 x_2-1.1667 x_3 0.5000 x_4-0.4258 x_1~2-0.9258 x_2~2-3.1758 x_3~2 .2500 x_1x_2 0.5000 x_1x3-1.5000 x_3x_4通过模型的主效应分析.得出了各环境因子对天敌捕食作用的影响。真水狼蛛对褐飞虱的日捕食量为19.372头。

| Abstract: | 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. |
