Tiny aphids or root lice that attack Vitis vinifera roots The disease was widespread in both Europe and California during the late 19th century, and returned to California in the 1980s
Any of numerous, chiefly North American, insect species (genus Phylloxera, order Homoptera), many of which are serious pests of plants. Phylloxera form galls on and can defoliate trees, especially hickory and pecan. See also grape phylloxera
A tiny aphidlike insect that attacks the roots of Vitis vinifera roots Terribly destructive, it once almost completely ruined the wine industry Continues to strike various areas of the globe from time to time Another disease attacking grape vines is Pierce's Disease The solution was to graft Phylloxera-resistant indigenous North American grapes roots to the European varietals
noxious plant louse which stings the vine to subsist, which causes the death of the stock In the nineteenth century, most of the French vineyard was ruined by this insect
Tiny aphids or root lice that attack vine roots The disease was widespread in both Europe and California during the late 19th century, and returned to California in the 1980s
It attacks the roots and leaves of the grapevine, doing great damage, especially in Europe
A insect (specifcally a plant louse) that attacks the roots of vines Phylloxera caused widespread damage in the wine producing countries of Europe and also in California during the latter half of the 19th century
Microscopic aphid which lives on vine roots by sucking their juice Unfortunately this isn't very good for most roots The aphid kills European wine varieties but native American vine roots are resistant
A tiny louse that attacks the root system of wine grape vines, responsible for killing over three million acres of vines in Europe in the 1800s Grafting to resistant rootstock is the only known way to combat this pest
> Tiny root-feeding aphid responsible for the destruction of more vineyards than any other pest or disease The spread of phylloxera is controlled by grafting disease-resistant rootstocks onto susceptible vines
A wine grapevine's main enemy, phylloxera is an insect that attacks vitis vinifera grapevines, eventually causing them to die A massive infestation of phylloxera took place in Europe and America in the late 1800s, wiping out millions of acres of grapevines During the plague it was discovered that America's vitis labrusca grapevines were immune to phylloxera From that time forward almost all vitis vinifera grapevines have been grafted onto vitis labrusca roots, which makes the vinifera vines highly resistant to phylloxera
Vine disease due to a small green-fly At the end of the 19th century, coming from America, the Phylloxera destroyed the 3/4 of the French vineyard Grafting saved French vines
A vine disease caused by an aphid attacking the roots Originally from America (where native vines were resistant) this disease has caused widespread global damage New vineyards are being planted on American resistant rootstock grafted with 'vitis vinifera' grape varieties
Microscopic aphid that lives on vine roots by sucking their juice It destroyed most of the world's vineyards in the late 19th century, and returned as a menace in California during the 1980s The aphid kills European vine varieties but native American vine roots are resistant; therefore the only way to defeat Phylloxera is to graft European wine varieties onto the resistant American vine roots
A tiny aphid-like insect that attacks the roots of grapevines, slowly starving the vine
