Viteus vitifoliae: galls in Vitis vinifera leaf

strongly galled leaf

gall

underside of the leaves with 3-7 mm larve pouch galls, open to the outside by a small opening in the upperside. The galls are strongly hairy, often red; inside a number of yellow aphids. Later in the season the aphids cause malignant growth on the roots.

hostplants

Vitaceae, monophagous

Vitis vinifera.

synonyms

Daktulosphaira vitifoliae; Phylloxera vastatrix (Planchon, 1868). The Aphid Species File (2014) convincingly argues that Daktulosphaira vitifoliae is the correct name, contrary to the Fauna Europaea.

notes

Introduced in the 19th century from North America into Europe, nearly causing the collapse of the French wine industry.
