Definition:a vineyard pest that was brought to Europe from its native America

Phylloxera vastatrix is the description for the vineyard pest that feeds on the roots and the leaves of a grapevine. The common European vine dies off once its roots have been infected by the pest. During the second half of the 19th Century, a whole of European viticulture had been affected and suffered damage. The only solution was to graft the scion of a European vine onto the rootstock of the phylloxera resistent American native vine variety, thus preventing complete devastation in the vineyards.
