| Abstract | Forty-three cucumber ?Cucumis sativus L.? cultivars were tested against two spotted spider mite ?Tetranychus urticaeKoch? and strawberry spider mite ?Tetranychus turkestani Ugarov & Nikolskii ?. The experiment was implemented in a randomized complete block design with 43 treatments (cucumber cultivars) and check treatments in greenhouse conditions between2015 and 2016. The results showed that the highest numbers of eggs laid per female per day by the T. urticae and T. turkestaniwere 8.98 and 9.23, respectively, which were recorded on the Taha cultivar. The lowest numbers of eggs laid per female per daywere 2.23 and 2.21 by the T. urticae and T. turkestani, on the Samer star and Danitu cultivars, respectively. The highest visualdamage ratings were recorded on the Taha cultivar (5.75 for T. urticae and 5.78 for T. turkestani) and the lowest damage ratingsof 2.49 and 4.25 were recorded on the Samer star and Storm cultivars for T. urticae and T. turkestani, respectively. Based on ourfindings, Taha cultivar was found to be a susceptible cultivar and Samer star cultivar proved to be a resistant one. These twocultivars could be used as differential hosts in further studies. |
