Exotic Pest Reporting
Eric LaGasa, Washington State Department of Agriculture, Bugwood.org
Apple Tortrix (Archips fuscocupreanus) is an insect pest of fruit trees. It is a native of Asia and was first detected in the Pacific Northwest in 1982.
The larval caterpillars normally feed on the leaves of plants, but also occasionally on the fruit or blossoms. Caterpillars can also damage trees by pruning leaves, flower parts or fruitlets to construct their shelters. When abundant, the caterpillars can defoliate fruit trees. Damage has been absent in northeastern orchards sprayed with active spraying programs.
