Stability and fitness costs associated with etoxazole resistance in Tetranychus urticae (Acari: Tetranychidae).

The two-spotted spider mite, Tetranychus urticae Koch, is one of the most important pests on a wide range of crops worldwide. Studies on stability of resistance and possible fitness costs associated with etoxazole resistance were carried out in T. urticae to provide basic information necessary to define effective acaricide resistance management strategies for this pest.
