Abstract

COTTON plant, Gossypium hirsutum L., is one of the most economic crop around the world and in GonbadKavous (located in North of IRAN) is an important COTTON cropping region. The spider mites (Tetranychus spp., Acari: TETRANYCHIDAE) are the most damaging pests on the field crops. Use of resistant cultivar is one of the foremost accepted chemical-free techniques for controlling this pest. A two year study was conducted to evaluate resistance of two most-cultivated cultivars, sahel and siokra, against spider mites. The results showed that there was a significant difference in population of spider mites, so that the population on Sahel was more than Siokra for two years studied. The separate population figures for each year recorded 10.3 ± 0.6 eggs and 24.2 ± 1.3 mites on Sahel, 7.4 ± 0.4 eggs and 15.9 ± 0.9 mites on Siokra in first year whereas it was 22.6 ± 2.1 eggs and 35.2 ± 2.6 mites and also 8.6 ± 0.5 eggs and 16.9 ± 1.1 mites in second year for them. Mite’s populations increased from mid-season to the end of growing period. The results showed that effects of ambient temperatures on egg populations and number of active stages of mites was more favorable on Sahel compared with Siokra. Population assessment of mites on these two cultivars can be used in management of the pest.
