The two-spotted spider mite, Tetranychus urticae Koch is one of the important polyphagous spider mite on a wide range of crops around the world. Control of the two-spotted spider mite populations mostly relies on the use of acaricides. Therefore, understanding the effects of sublethal concentrations of acaricides using demographic toxicological analysis is important for successful management of this pest. In this study sublethal effects of Payton® (chlorfenapyr SC 360) including LC10, LC20, LC30 and distilled water (control) were evaluated on some biological parameters of T. urticae. The sublethal concentrations were determined using the leaf dip bioassay on the adults stages. The leaf discs were immersed for 15 seconds at concentrations after them dried in room condition and twenty same aged adults from both sexes (10:10) were transferred to the each leaf disc. The experiments were done under laboratory condition at 25±2 ºC, 60±5% RH, and a photoperiod of 16:8 ( L: D ) hours on bean (Phaseolus vulgaris L.). The raw data were analyzed according to the theory of age-stage, two-sex life table. The longevity and total life time of male and female mites treated with LC20 and LC30 concentrations was decreased significantly in comparison with control. Oviposition period was scored 9.70 days for control treatment while the minimum values was obtained 6.67 days for cohort treated by LC30. The intrinsic rate of increase (rm) for mites treated with LC20 and LC30 were 0.1841 and 0.1763 day-1. According to result this investigation, the sublethal concentrations (LC20 and LC30) of chlorfenapyr indicated significant effects on all life table parameters (GRR, R0, rm, λ). These laboratory results indicate that sublethal concentrations of chlorfenapyr could be useful in the integrated management of this pest.
