Summary:

In this study, the demographic parameters of Tetranychus urticae Koch, a spider mite that is considered as one of the most important greenhouse pests were evaluated in 16L:8D, 14L:10D, 12L:12D, 10L:14D and 8L:16D photoperiods and temperatures of 20±1, 25±1 and 30±1˚C. Then, the effect of three pesticides, Dayabon, Oberon and Abamectin on mortality of preyed mites were studied at long-day 16L:8D and short-day 12L:12D regimes at 25 and 30˚C. According to the demographic results, the intrinsic rate of population increase (rm) in 12L:12D photoperiod and temperatures of 20 and 25 ˚C (0.110 and 0.186 day-1, respectively) compared to the control (0.200 and 0.284 day-1, respectively) have been significantly decreased. The pre-oviposition period at 12L:12D photoperiod and the aforementioned temperatures were 2.095 and 1.066 days in the control and 1.222 and 1.068 days, respectively, in the control and the mean fertility were obtained 51.840 and 44/705 eggs per female compared to control 122/333 and 116/100 eggs per female, respectively.
