In a study conducted during 1999 in Sunchon, Korea, the relative toxicity of ten acaricides, seven insecticides and five fungicides against the two-spotted spider mite, T. urticae and its predator, P. persimilis in Phaseolus vulgaris var. humilis was evaluated using leaf spray bioassay. Six acaricides (bifenazate, etoxazole, acequinocyl, fenbutatin oxide, flufenoxuron and chlorfenapyr) were less toxic to P. persimilis adult females than to T. urticae adult females.
