  This study aimed todetermine the applicability of Amblyseiussp. (Acarina: Phytosiidae) to control the red spider mite Panonychus citriKoch (Acarina: Tetranychidae). In orange trees,the density of red spider mite risesfrom the beginning of September and attainsthe pick inthe middle of October. The population of the predatory spider mite was harmony with the red spider mite. The occurenceand increaseof predatory spider mite were the factors leading the reduction of red spider mite population. Reproductive time of predatory mite lasted long (13-15 days in average), and the mean total eggsof one female was 21.86. The predation rate of Amblyseiussp. atdifferent stages showedthat mature femalesconsumed eggs significantly higher than other stages and mature males. However, the mature femaleshad significantly lower predation at adult stage of prey.
