Grape phylloxera (Daktulosphaira vitifoliae (Fitch ); family Phylloxeridae, within the order Hemiptera, bugs); originally described in France as Phylloxera vastatrix; equated to the previously described Daktulosphaera vitifoliae, Phylloxera vitifoliae; commonly just called phylloxera (/ f ɪ ˈ l ɒ k s ə r ə /; from Ancient Greek: φύλλον, leaf, and ξηρός, dry) is a pest of Class: Insecta.

Daktulosphaira vitifoliae (Fitch) {Also known as Viteus vitifoliae (Fitch)}. Taxonomic placing: Insecta, Hemimetabola, Hemiptera, Sternorrhyncha, Aphidoidea, Phylloxeridae. Common name: Grape phylloxera. Geographical distribution: A North American species that now occurs in the majority of grapevine-growing Map #, Host plants: Various species of Vitis.

Abstract. The management options for grape phylloxera, Daktulosphaira vitifoliae, a monophagous insect pest of Vitis species are reviewed. Although in a worldwide context, grape phylloxera is managed predominantly by the use of resistant rootstocks developed through conventional breeding of hybrid crosses of American Vitis species, this management aspect is.

Grape phylloxera, Daktulosphaira vitifoliae (Fitch) (Hemiptera, Phy- lloxeridae), is a major pest of cultivated grapevines Vitis spp. (Vitaceae) worldwide (Powell, ). Grape phylloxera, Daktulosphaira vitifoliae (Fitch), is a small, invasive, sap-sucking insect (Family Phylloxeridae) that causes substantial physical and economic effects on commercial grapevine, Vitis vinifera L., production.

Grape phylloxera is native to the Northeastern United States(Wapshere&Helm,)andwasunintentionally.

Grape Phylloxera, Daktulosphaira vitifoliae Host: All stages of this insect feed exclusively on grapes. Symptoms: Phylloxera feeding causes gall formation on leaf and root tissue.

These formations can eventually result in rotting of the root, yellowing of the grape foliage and a general overall decline in plant vigor. If roots of European vines. Phylloxera is managed solely by resistant Daktulosphaira vitifoliae book.

Weak rootstocks have often failed; strong ones have not. We have no reliable backup management tactics if strong rootstocks were to fail. We will determine this risk by studying rootstock failures. We will then use weak links in phyl-loxera and associated pathogen biology to develop management tactics and tactics.

Introduction. Grape phylloxera, Daktulosphaira vitifoliae (Fitch) (Hemiptera, Phylloxeridae), is a major pest of cultivated grapevines Vitis spp. (Vitaceae) worldwide (Powell, ).The root-feeding stages cause most economic damage and most research to date has focused on this part of the life by: In laboratory bioassays with grape, Vitis vinifera L., roots, grape phylloxera, Daktulosphaira vitifoliae (Fitch), did not develop beyond egg hatch when held at a constant 18°C.

Phylloxera definition is - any of several plant lice (family Phylloxeridae); especially: one (Daktulosphaira vitifoliae synonym Viteus vitifoliae) originally of North America but introduced into Daktulosphaira vitifoliae book and elsewhere that produces galls on the leaves and roots of Daktulosphaira vitifoliae book vines and is a serious pest especially of vinifera grapes in wine-producing regions.

Grape phylloxera is a tiny aphidlike insect that feeds on roots of Vitis vinifera grape and certain rootstocks, stunting growth of vines or killing them. This pest prefers heavy clay soils that are found in the cooler grape-growing regions of the state such as Napa, Sonoma, Lake, Mendocino, and Monterey counties, as well as the Sacramento Delta and the.

Grape phylloxera, (Homoptera: Phylloxeridae), is a worldwide pest of grapevines. Its life cycle has sexual and asexual portions with forms that feed from leaf and root galls.

Not all forms occur throughout the insect's range. Root forms predominate on cultivars; leaf forms predominate on other species characteristic of the American native range.

Egg-hatching and life-table parameters were determined at temperatures ranging from 7 to 39°C and 16 to 32°C, respectively. The percentage of eggs hatching decreased at temperatures of ≤16°C and >36° by: Grape tumid gallmaker – smooth rounded galls on leaves, shoot tips, rachises Biology There are two forms of phylloxera: one that creates galls on the roots and another that affects leaves.

Although the two forms behave differently, both belong to the same species. Grape phylloxera, Daktulosphaira vitifoliae (Fitch), is a destructive insect pest of cultivated grapes, Vitis vinifera L., worldwide. Rootstocks based on American Vitis species support only very low populations of root-feeding grape phylloxera and vines do not exhibit damage symptoms of that activity.

It is thought that the mechanism of the resistance involves Cited by: 7. The Great French Wine Blight was a severe blight of the midth century that destroyed many of the vineyards in France and laid waste the wine industry.

It was caused by an aphid (the actual genus of the aphid is still debated, although it is largely considered to have been a species of Daktulosphaira vitifoliae, commonly known as grape phylloxera) that originated in North.

Grape phylloxera, (Phylloxera vitifoliae), a small greenish-yellow insect (order Homoptera), highly destructive to grape plants in Europe and the western United States. Their sucking of fluid from grapevines results in formation of small galls on leaves and nodules on roots, which result in eventual rotting of the plant.Phylloxera is a nearly microscopic root louse or aphid, that primarily attacks the roots of Vitis vinifera grapevines, in much the same way an aphid attacks a tomato plant's stems and leaves, by puncturing the vessels and sucking out the plant's infested with the phylloxera louse, the grapevine's root system can become severely impaired, making it difficult for the plant to .early detection of grape phylloxera (daktulosphaira vitifoliae fitch) infestation through identification of chemical biomarkers.
