Grape phylloxera, Daktulosphaira vitifoliae (Fitch) (Homoptera: Phylloxeridae), is an aphidlike insect that feeds aggressively on grape roots. Phylloxera is native to the eastern and southeastern United States, where native American grape species coevolved with the insect.
Many factors can cause distorted growth in grapevines. One cause of distorted growth is a disorder known as Short Shoot Syndrome (SSS), which is associated with mite feeding damage. However, similar abnormal growth symptoms can be caused by spring frost damage, herbicide damage, vine imbalance (overcropping of vines), nutrient deficiency...
