Monitoring acaricide resistance and the frequency of associated target‐site mutations in Tetranychus urticae populations from rose glasshouses in China

The two-spotted spider mite, Tetranychus urticae, is a serious pest of glasshouse roses. The rapid development of resistance to acaricides has severely impacted rose production. To investigate the resistance status of T. urticae in glasshouse rose cultivation in China, we tested the susceptibility of 10 populations to 12 commonly used acaricides and examined the frequency of target-site mutations associated with acaricide resistance.
