Abstract :The two-spotted spider mite, Tetranychus urticae Koch, was tested for susceptibility to various acaricides, propargite insert ignore into journalissuearticles values(Omite); 570 g l-1, amitraz insert ignore into journalissuearticles values(Kortraz); 200 g l-1 and abamectin insert ignore into journalissuearticles values(Agrimec); 18 g l-1. Propargite, a selective acaricide, has been used to control T. urticae in many crops in Turkey. Amitraz and abamectin have acaricidal and insecticidal properties, and are thus used to control spider mites and some vegetable pests insert ignore into journalissuearticles values(e.g., whiteflies and Liriomyza spp.);. Five different T. urticae populations collected from vegetable greenhouses in Isparta and their responses to those acaricides were investigated by leaf dip assay and compared with those of a susceptible reference strain. Resistance ratios for the chemicals ranged from
