During recent years mites are increasingly becoming serious pests of horticultural crops including ornamental and medicinal plants. Many of the mite species were assumed major pest status because of the elimination of natural enemies caused by the indiscriminate application of pesticides (Subhasree et al., 2015). Predatory mites are the promising bio control agents of phytophagous mites. Predatory mites of the family Phytoseiidae has been generally considered to be the most promising group of predators of pest mites on different crops (Gerson et al., 2003) and other small arthropods. They feed upon injurious plant feeding mites of the families Tetranychidae, Tenuipalpidae and Eriophyidae (Tuttle and Muma, 2003). Several biological and ecological studies have shown that mites of this family are potentially important as biotic factors in the natural or biological control of injurious plant feeding mites. According to Beaulieu et al. (2011) about 2,300 species of phytoseiids belonging to
