Mites play an important role as pests threaten a wide range of plants including cotton that consider the preferred host to Tetranychus urticae Koch the dominant phytophagous mite allover the world (Carey, 1983 in California; Shi and Wu, 1985 in Japan; Wilson and Morton, 1993 in Australia; Sirjani and Arbabi, 2005 in Iran; Demirel and Cabuk, 2008 in Turkey and El-Saadany et al, 1977; Zaher, 1984; Ali and Aly, 1989; Taha et al, 1990 and Abdallah and Kelany, 2003 in Egypt,). Significant reductions in cotton yield, fiber quality and seed viability were related to the infestation by T. urticae (Wilson et al 1991 and Wilson, 1993). Sadras et al (1995) explained that mites can reduce the oil content of cotton seed. Soil mites in different plants act as fungivorus, parasite or predator to egg stages of some insects, so these mites may be impact the plant anywise.
