Grape phylloxera (Daktulosphaira vitifolii) is a destructive aphid pest that lives on the roots of grapevines. Phylloxera aphids feed by sucking fluids from grapevine roots, which causes a progressive decline in the vigour of infested vines.
European (Vitis vinifera) grapevines, which comprise the vast majority of Australian vineyards, have very little tolerance to phylloxera, which therefore represents a major threat to the industry.
The Phylloxera and Grape Industry Board of South Australia provides more information about phylloxera (external link).
High risk materials
Phylloxera is most commonly spread through transportation of materials such as:
- grapevines, including cuttings and rootlings
- whole wine grapes
- grape marc and must
- sample material for analysis
- soil
- machinery, packages or equipment used in the cultivation or harvesting of any of these materials.
You must check these materials carefully and follow appropriate procedures before transporting them.
Do not transport any materials that may have come in contact with phylloxera.
