Agrilus derasofasciatus

Jewel beetle Agrilus derasofasciatus

Description

Agrilus derasofasciatus is a small jewel beetle species (4.0–5.5 mm) developing under the bark of grapevine (Vitis vinifera). The beetle has a univoltine life cycle and completes development within one year. Adults are active from May to July. Females lay eggs on weakened or naturally growing vines, including ornamental or wild grapevines. Larvae create narrow, winding galleries in the cambial layer. Although its impact is generally minor, in places with abundant wild or neglected vines, higher population densities may lead to more visible damage. The species is found locally in Central and Eastern Europe, including areas with urban or abandoned vine growth. In cultivated vineyards, its significance is usually negligible, but local outbreaks may occur in unmanaged habitats.

Symptom

On affected grapevines are visible serpentine larval galleries under the bark and on the leaves may be present adult beetles.
