Clavigesta sylvestrana

Pine shoot moth Clavigesta sylvestrana

Description

Clavigesta sylvestrana, also known as the pine shoot moth, is a small moth species that primarily targets coniferous trees, particularly Scots pine (Pinus sylvestris), maritime pine (Pinus pinaster), and other pine species. The larvae bore into the shoots and stems of the host trees, causing damage that weakens the tree and hampers its growth. The moth is widely distributed across Europe, especially in south regions with extensive pine forests. Common in Mediterranean Europe, less common in northern areas of Europe. Adult moths are typically active in late summer, laying eggs on young shoots. The larvae overwinter within the shoots and resume feeding in spring, which can lead to branch dieback and deformed growth in the following growing season. Clavigesta sylvestrana is considered a significant pest in forestry, especially in commercial pine plantations.

Symptom

Symptoms include damaged and deformed pine shoots, dieback of young branches, and resin exudation from the larvae's entry points. Severe infestations can lead to stunted growth and weakened trees.
