Effects of cyflumetofen and clofentezine were evaluated on Tetranychus urticae Koch, under laboratory conditions. LC50 values of cyflumetofen and clofentezine against eggs were 0.8 µg a.i./mL and 0.42 µg a.i./mL, respectively. Sublethal effects of these compounds on the life table parameters of T. urticae were evaluated by exposing mites to LC50 and LC25 concentrations. The developmental time of male and female T. urticae were significantly affected by both acaricides. Moreover, exposure to LC25 and LC50 concentrations of cyflumetofen or clofentezine significantly reduced net reproductive rate (R0), finite rate of increase (λ), and intrinsic rate of increase (r). The LC25 and LC50 treatments showed strong effects on both survivorship, fecundity, and intrinsic rate of increase. Our findings indicated that lethal and sublethal exposure to cyflumetofen or clofentezine result in significant alteration of life-history characteristics of T. urticae. Our findings suggest that these acaricides are promising candidates for use in management programs of this major pest.
