Subject: European fruit tree tortrix detected in Washington State (USA)
Date posted: April 01, 2002
Source: Washington Department of Agriculture
In summer 2000, during a survey for European corn borer, specimens of the European fruit tree tortrix (also called great brown twist moth), Archips podanus, were caught in Whatcom county, Washington, on the border with Canada. This is the first report of this species in the United States. Archips podanus was first described from North America (British Columbia and Ontario) in the late 1950's, but was misidentified as A. oporanus. While A. oporanus feeds primarily on conifers, A. podanus is highly polyphagous, damaging the fruit of Rosaceae and feeding on the foliage of forest and ornamental trees, including maple, oak, elm, walnut and pomegranate. Its primary hosts are quince (Cyndonia oblonga), apple (Malus pumila), and European pear (Pyrus communis); in the lower Fraser Valley of British Columbia, it is reported to feed on apple, plum and blueberry.
