Abstract

In 1972, an organophosphate resistant strain of the phytoseiid predator Amblyseius fallacis (Garman) from Michigan compared favourably with the endemic Typhlodromus occidentalis Nesbitt, from Summerland, B.C., in laboratory and greenhouse trials against European red mite, Panonychus ulmi (Koch), and was later released into an orchard. By August 1972, A. fallacis had decreased whereas population densities of T. occidentalis increased. Examination of leaves and bark from the trees, and weeds, grass, and litter beneath the trees in 1973 confirmed that A. fallacis failed to survive in the Okanagan environment.
