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

Multiple-acaricide resistance exists extensively in all collected populations. The high resistance levels of collected populations to many acaricides, together with multiple target-site mutations, indicate a serious resistance status of T. urticae in rose glasshouses in China. The role of the newly discovered I136A mutation in bifenazate resistance requires further verification. These results will be essential for implementing a well-thought-out resistance management program for rose cultivation in China. © 2024 Society of Chemical Industry.
