Predatory mites have been used to control T. urticae, but chemical applications are often necessary during outbreak conditions. Certain acaricides are compatible with P. persimilis and may shape the age structure of T. urticae in a manner that affects biological control. We first determined how several acaricides affected T. urticae age structure. Then, greenhouse trials were conducted applying acaricides followed by a release of P. persimilis to determine whether combination treatments enhanced suppression of T. urticae
