The blue-green sharpshooter transmits Xylella fastidiosa, a bacterium that is especially deadly for some grape crops, especially in California. Xylella fastidiosa infects many plant species, but not all plants are susceptible to the effects of infection. The bacterium that causes Pierce's disease in grapes, and peach leaf scorch and wrong disease in many parts of the country, especially in the Southeast. The error rather feed on woody plants, especially along stream banks. There is no cure for Xylella fastidiosa diseases. Adult blue-green sharpshooter. Their colorful name from their bright, blue-green head, wings and thorax The bug has yellow legs and is about 1/4 inch long.
Blue-green sharpshooter love wine but also on alfalfa to feed blackberry, elderberry and mugwort. The bug feeds on roses, fuchsias and ivy, and trees such as almond, elm, peach, pear and sycamore. Blue-green sharpshooter can also attack citrus, maple, mulberry and oak trees, and have been on oleander shrubs also found. The error and the bacteria they spread are most active in areas with mild winters.
In coastal California, Pierce's disease can be fatal if it infects a vineyard. The disease occurs along the Pacific coast of Central America, including British Columbia. The insect preferred riparian areas, which means it most productively along streams, springs and rivers. In addition to blackberries, elderberries and cultivated vineyards, wild grapes is an important host for Pierce's disease. Blue-green sharpshooters overwinter in vegetation and bugs slip 'from May to July. As bugs feed, they infect plants. Seedlings and plants under stress, such as drought are more susceptible to the disease. Pierce's disease affects the plant's ability to take and hold moisture, leading to dry the leaves and eventually the whole plant and die. In the southeast and some wild muscadine grape hybrids are less susceptible to Pierce's disease.
Blue-green sharpshooters are responsible for the adoption of a variety of leaf scorch disease on both U.S. coasts. Oleander leaf scorch causes yellowing of the leaves, the dying of the woody parts of the plant and any attachments death. This disease is prevalent in Southern California, Texas and Arizona, and can spread to other parts of the South. Leaf scorch of sycamore, oak and elm caused death of twigs and branches. Almond leaf scorch turns brown leaf margins, said. A band of yellow on the inner surface of the sheet Death begins at the tips of stems and moves inward, and the almond tree growing in a slow but steady decline, which eventually leads to death.
Phony Peach Disease
Blue-green sharpshooters in the southeast also transmit Xylella fastidiosa that. Stunts the growth of peach and reduces the plants ability to absorb and retain moisture The fruit and leaves dark and flat as they dry. Phony peach disease occurs mainly in the Southeast. While the disease inhibits the growth and productivity of trees and may even prevent peach trees of fruit in general, it does not scald the leaves, as if it has affected plum trees.
