Sublethal effects of fenazaquin were investigated on life-table parameters of Tetranychus urticae Koch(Acari: Tetranychidae) in the laboratory condition. After a 48 h exposure to LC30 concentration, mortality,fecundity and longevity in the females that survived of treatment were determined. Results showed thatfenazaquin caused significant reductions in fecundity and longevity of adults. Life table assay indicated thatthe intrinsic rate of increase (rm), net reproductive rate (R0), finite rate of increase (λ), mean generation time(T) and doubling time (DT) significantly reduced in treated females compared to control. The results of thisstudy could be seen as a starting point for further research in order to improve the management of T. urticaepopulations.
