%X Beans are widely cultivated worldwide and are consumed as an important food source. Tetranychus urticae is one of the most important pests of beans. In this study, optimization of acaricide use was carried out using a central composite design and response surface statistical method using Design Expert 7.00 software to reduce the use of chemical pesticides and investigate the best conditions for maximum mortality and adult mites. The process input variables were considered in the temperature range of 25–30 °C, relative humidity of 55–65%, and application doses of 125-1500, 900-2300, and 69–2330 μl/l for the acaricides fenpyroximate, propargite, and fenazaquin, respectively. The bean leaf disc method was used for bioassay tests. The results of variance analysis confirm the statistical significance of the linear model and the factors of dose and relative humidity with the best maximum mortality point of the adult ticks of the acaricide fenpiroximate at H: 57.03% and D: 14.1045 µl/ 1000 ml H2O, M: about 22%, and the significance of the quadratic model 2FI, the interaction effects of temperature and relative humidity for the acaricide propargite with the lowest dose, T: 26.01 ºC and H: 62.97%, M: about 16%, and the significance of the linear model combined with the relative humidity factor for the use of the acaricide fenazaquin with the best maximum mortality point of the adult ticks at H: 62.97%, D: 527.30 µl / 1000 ml H2O, M: about 9% which are the most favorable conditions for the use of the above three acaricides.
