The use of pheromone mating disruption, horticultural oils and some of the more selective reduced-risk insecticides and miticides will allow a natural increase of predators capable of regulating pest mite populations to tolerable levels without the use of miticides. The potential savings to Pennsylvania apple growers is approximately $1 million per year and a reduction of almost 1 ton of miticide active ingredient into the environment. Mite control through biological control in apple has the additional advantage of stopping the development of miticide resistance and, once established, is sustainable long-term if the use of certain harmful pesticides is avoided.
