This aphid-like insect was first noted as a problem when European grape vines (Vitis vinifera) were brought to the east coast of North America. These immediately died due to the pest, which also dwells harmlessly in the roots of native grapes of the region. Unfortunately, in the 1800s some shmuck accidentally introduced this to Europe while bringing American vines to the area. The insect went on a rampage and almost ruined the European wine industry. Luckily, someone discovered that if you graft European vines onto the roots of American varieties, they will remain unaffected by the insect. Now, throughout the world, this is how grapes are grown.
