The two-spotted spider mite, Tetranychus urticae Koch is key pest in greenhouse vegetables, ornamental plants and many fruits. Farmers generally prefer chemical control to suppress this species. However, due to its biological properties, resistance to many pesticides develops For this reason, biological control or integrated control method are recommended for suppress of this species. In this study, the effects of some pesticides against Tetranychus urticae and Phytoseiulus persimilis was investigated. Pesticides having active ingredients such as etoxazole, bifenthrin, cyromazine, acequinocyl were used. Recomended dosages of all pesticides were applied to larvae and adult of both mite species by petri dish spray tower method. According to the mortality data, the effect of the pesticides was calculated using the Abbott formula. Effect of the pesticides having various active agents on T. urticae and P. persimilis were compared regarding their efficiency. According to the results, bifenthrin and acequinocyl showed efficiency between 90-100% on both life stages of T. urticae and P. persimilis. Etoxazole and cyromazine caused more than 90% in both life stages of P. persimilis to die. While 100% mortality was observed in T. urticae larvae treated with etoxazole, cyromazine had no significant effect on both stages of T. urticae.
