Abstract

Phytoseiulus macropilis (Banks) and P. persimilis Athias-Henriot similarly suppressed Tetranyehus urtieae Koch populations on greenhouse ornamental plants in Florida and Ohio experiments. Observations indicated the importance of introducing predators into low-density spider mite populations, since 1 to 3 weeks were required to effect control.
