Abstract:	In the middle of the 19th century grape phylloxera (Dactulosphaira vitifoliae) was imported into Europe from North America. Viticulture was nearly broken down due to phylloxera outbreak and other diseases in the late 19th and early 20th century. The American grape vines are mainly susceptible in the leaves but resistant or tolerant in the roots. By contrast, the European grape vine, Vitis vinifera, shows the opposite susceptibility and tolerance phenotype. Therefore, the pest was managed successfully by grafting scions of V. vinifera grape cultivars on American rootstocks. But producers which are cultivating American-European hybrid cultivars such as Léon Millot ((V. riparia x V. rupestris) x Goldrieslingor) and Maréchal Foch ((V. riparia x V. rupestris) x Goldrieslingor) have often high infestation rates with up to 150 galls per leave. We investigated the distribution of grape phylloxera in Switzerland. First results will be presented.
