Flufenoxuron displayed various effects on the two spotted spider mite Tetranychus urticae Koch according to the age and the concentrations tested. Generally, younger immatures were rather susceptible than the older ones. The duration of the developmental period increased due to treatments and reproduction of the succeeding females, at the different concentrations. The number of eggs/male/10 days was fewer than in the control. Treated females at concentrations ranged between 400 - 20 ppm, produced none-viable eggs and viability increased by decreasing the concentration down to 1 ppm
