Cydia pactolana
Spruce bark tortrix Cydia pactolana
Description
The spruce bark tortrix is a small moth with a wingspan of approx. 13–15 mm. In May and June the females lay eggs under the bark scales on branch nodes or other parts of 10–20 year old spruce stems. The larvae hatch
in June, mine under the bark and tunnel 5–6 cm long galleries. Overwintering inside the larval galleries, they pupate in spring. The presence of the caterpillar is indicated by resin flow and frass coming out from the larval tunnel. Can cause damage mainly in young spruce stands (Christmas tree plantations) when abundant. The feeding damage induces galls on the injured parts, disfiguration of trees and secretion of resin. Minor damage usually heals rapidly. Not rare in Central Europe.
Symptom
Thickening of the stem. Presence of excrements.
