TL;DR: Grape phylloxera, Daktulosphaira vitifoliae (Homoptera: Phylloxeridae), is a worldwide pest of grapevines with sexual and asexual portions with forms that feed from leaf and root galls.
Abstract: ▪ Abstract Grape phylloxera, Daktulosphaira vitifoliae (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 Vitis vinifera cultivars; leaf forms predominate on other Vitis species characteristic of the American native range. Other conditions influence expression of the life cycle. Hosts and conditions similarly affect life table performance. Damage to grapevines is by secondary soilborne pathogens attacking the feeding site and by physiological interaction of the insect with the grapevine, though the latter has not been well studied. Resistant rootstocks derived from native American Vitis are the primary control tool. The insect varies genetically and relative to performance on hosts. Use of insecticides is limited in effect, and other control methods are not proven. More research on the biology, ecology, and management of phyl...

TL;DR: Foliar jasmonic acid application at concentrations that caused no phytotoxicity significantly reduced the performance of both herbivores and appeared to be caused by changes in fecundity for the Pacific spider mite, and possibly changes in development rate and FEC for grape phylloxera.
Abstract: We investigated the effects of induced resistance to the folivore Pacific spider mite, Tetranychus pacificus McGregor (Acari: Tetranychidae), as well as the root-feeding grape phylloxera Daktulosphaira vitifoliae (Fitch) (Homoptera: Phylloxeridae) in grapevines using exogenous applications of the natural plant inducer, jasmonic acid. Foliar jasmonic acid application at concentrations that caused no phytotoxicity significantly reduced the performance of both herbivores. There were less than half as many eggs produced by spider mites feeding on the induced leaves compared with control grapevine leaves. Induction reduced the numbers of phylloxera eggs and nymphal instars by approximately threefold and twofold, respectively, on induced compared with control grapevine roots. The negative demographic effects of jasmonic acid application appeared to be caused by changes in fecundity for the Pacific spider mite, and possibly changes in development rate and fecundity for grape phylloxera.

TL;DR: Grape phylloxera obtained from Rutherford, Calif., appeared to overcome the resistance of the hybrid grape rootstock, Ganzin 1, in the field, and indicate a potentially serious problem for California vineyards in coastal valleys where phytoxera are established.
Abstract: Grape phylloxera ( Daktulosphaira viiifoliae Fitch) obtained from Rutherford, Calif, appeared to overcome the resistance of the hybrid grape rootstock, Ganzin 1, in the field These insects were reared in the laboratory and compared with phylloxera from another Napa Valley location in an excised root life-table experiment The Rutherford phylloxera (type B) developed and laid eggs quicker and had a greater fecundity than the Napa phylloxera (type A), as indicated by life-history parameters of generation time, gross and net reproductive rates, and doubling time On the highly resistant rootstock, St George, a pure Vitis rupestris (Scheele) selection, the type-B phylloxera were also able to establish and reproduce better than type-A phylloxera On the susceptible V vinifera L variety, Cabernet Sauvignon, both phylloxera types did equally well These data indicate a potentially serious problem for California vineyards in coastal valleys where phylloxera are established
