Cherry Bark Tortrix Moth
Carroll, Juliet; Della Rosa, Linda
A relatively new exotic pest in North America, cherry bark tortrix was found in British Columbia in 1989, in Washington in 1991, spread to Oregon, and has now established itself as a pest of ornamental cherries in the Pacific Northwest. Cherry bark tortrix is known throughout Europe, south to coastal North Africa and west to Siberia. In its native homeland, because parasitic wasps and other natural enemies keep populations low, it rarely causes economic damage or requires treatment. However, because cherry bark tortrix is an introduced pest in the Pacific Northwest, natural enemies have not yet appeared to a significant degree. Larvae tunnel into the bark and feed on phloem tissues, causing damage to trunks and major limbs. The insect infests trees in the rose family, including cherry and apple.
