Abstract: 

Two-spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae) is an important pest of ornamental plants such as rose in many regions of the world. Reproductive parameters of this mite were evaluated on 10 roses cultivars, including Valentine, Pink, Yellow, Roulette, Tea, Marusya, Cool water, Dolcevita, Bella vita and Orange in a growth chamber at 24±1oC, 65±5% RH and 16 L and 8 D. Results showed that the gross and net fecundity rate were significantly different on rose cultivars. The highest gross and net fecundity rates were calculated on the Pink cultivar (113.86±11.50 and 84.64±8.10, respectively). Also, the highest gross and net fertility were observed on the same cultivar (94.89±9.57 and 70.54±7.50, respectively). Mean eggs per female per day and mean fertile eggs per female per day were significantly different among the rose cultivars, and the value of these parameters were the highest on the Orange cultivar and lowest on the Cool water cultivar. The life expectancy at adult emergence was highest on the Pink and the lowest on the Bella vita. Based on the results, it could be concluded that the Pink cultivar is the most suitable host plant among the examined rose cultivars for the reproduction of two spotted mite.
