Abstract:The Foraging behavior of four predators (Sfethor us chenqi,Agistemus ext-sertus,AmbIyseius nichols,Amblyseius vulgaris) for citrus red mite(Panonychus cifri)was investigated, as well as how the interference among and within species occurs, by using the rotational composite design of quadratic regression. The predation model of the four predators to citrus red mite was obtained: Y = 13.7569 + 1.4583P1 + 0.3750P2 + 0.3750P3 + 0.1250P4 + 11. 0417 X-0.0625P2X+0.1875P3P4+0.0625P3X + 0.1875P4X - 0.6354P12 - 0.385...
