In 1965, strains of the predaceous phytoseiid mite, Typhlodromus occidentalis Nesbitt, had developed resistance to azinphosmethyl, one of the organophosphate insecticides used to control the codling moth, Laspeyresia pomonella (L.). From 1966 to 1968, trials with integrated mite control in growers’ orchards were carried out successfully preserving the predator T. occidentalis. In most cases, an application of oil at the half-inch green bud stage was applied. The integrated concept of orchard mite control was recommended to the British Columbia fruit industry in 1969 and gained wide acceptance. In 1974, a survey of eight of the original integrated control orchards revealed that none of them had been treated with a summer acaricide since 1968. In six orchards, application of oil at the half-inch green bud stage had been used annually but two had not even received the oil spray. In all the orchards there was a good biological balance of a few predators and a few prey.
