The experiments were carried out to screen okra cultivars/genotypes against two spotted spider mites, Tetranychus urticae Koch in the field conditions at Instructional Farm, College of Agriculture, JAU, Junagadh, Gujarat during Kharif 2014 and 2015. Among the various okra cultivars/genotypes tested on the basis of mite incidence, categorization of cultivars/genotypes and yield of okra fruits, cultivar GAO-5 emerged out as highly resistant to T. urticae with lowest mite population and highest yield. Cultivars Arka anamika, GO-2, Arka abhay, GJO-3 and JOL-10-18 were found resistant, whereas JOL-5S-3, Pusa sawani and JOL-1 were susceptible. In contrast to this, Parbhani kranti was recorded as a highly susceptible cultivar.
