Phylloxera is the most damaging vine pest in Europe and Western United States, and damage is more important in newly-planted vineyards than in 10-year old ones. There are also differences in tolerance or resistance between the species; therefore, Vitis vinifera is very sensitive to the attack of the root form, but its leaves are resistant, while the American species Vitis viparia does not allow a large number of galls on its leaves, but is resistant to the root form. But, if foliar infestation is not too high, it has no economic effect whatsoever on the vines or quality and quantity of wine produced from the vine. The goal of research was to monitor and point out the attack degree of the species Phylloxera vastatrix, a quarantine pest A 2 of the OEPP and Apothem studies were carried out on vine nurseries, mother-plantations, and port-graft plantations in the Timiş County, between April and August 2007, together with the Phyto-Sanitary Unit of Plant Protection of the Timiş County. In order to identify the characteristic symptoms on the leaves, the control was done randomly, all during the vegetation period, starting from the end of April and the beginning of May. As a result of research, we could note a medium attack by phylloxera, the gall form and with no root form whatsoever, in the Timiş County; we issued warning bulletins in problem areas and we recommended the use of resistant graft-carriers.
