Description

Major hosts: Vitis vinifera (grapevine)
Minor hosts: Vitis aestivalis (Summer grape), Vitis labrusca (fox grape) and Vitis riparia (riverbank grape (USA).

The principal economic hosts of grapevine phylloxera are species of Vitis. There are large differences in tolerance or resistance between species: roots of V. vinifera are extremely susceptible to attack by the radicicolae (the root-feeding form), but the leaves are resistant, whereas the American species, V. riparia, withstands extensive galling of the leaves, but is resistant to root attack. V. riparia is therefore widely used in interspecific hybrid rootstock production.
