Lethal and sublethal effects of fenazaquin were studied on life-table parameters of Tetranychus urticae Koch in laboratory condition. Results showed that LC50 and LC30 of fenazaquin on T. urticae were 101 and 60.2 ppm, respectively. In assessing sublethal effects, mortality, fecundity and longevity of the females that survived from the treatment were determined after a 48 h exposure to LC30 concentration. Results showed that fenazaquin caused significant reductions in fecundity and longevity of the adults. Life table assays indicated that the intrinsic rate of increase (rm), net reproductive rate (R0), finite rate of increase (λ) and mean generation time (T) significantly reduced in the treated females compared with control, while doubling time (DT) significantly increased in the treated female. The results of this study might be seen as a starting point for further research in order to improve the management of T. urticae populations.
