What do glassy winged sharpshooters eat?

Glassy-winged sharpshooter (GWSS) is native to the southeastern United States and northeastern Mexico (Fig. 1). This cicadellid feeds almost exclusively on xylem fluid, a low nutritional quality food, which results in insects ingesting over 100× their bodyweight in fluid each day.

Why is the glassy-winged sharpshooter bad?

The glassy-winged sharpshooter is a serious pest of grapes because it acts as a vector of the strain of Xylella fastidiosa that causes Pierce’s disease in vineyards. It also vectors the strain that causes oleander leaf scorch in oleander.

How do you control the sharpshooter?

A healthy population of beneficial insects is the single most effective way to control sharpshooters. One of the most effective is a small wasp that feeds on the pest’s egg masses. Praying mantis, assassin bugs and lacewings are also extremely beneficial at managing glassy winged sharpshooters.

Where is the glassy winged sharpshooter from?

How does Pierce’s disease spread?

Pierce’s Disease is a deadly disease of grapevines. It is caused by the bacterium Xylella fastidiosa, which is spread by xylem feeding leafhoppers known as sharpshooters. Pierce’s Disease is known to be prevalent within the USA from Florida to California, and outside the USA in Central and South America.

Is there a cure for Pierce’s disease?

The University of California reported that the disease destroyed over 1,000 acres of grapevines in northern California between 1994 and 2000, causing $30 million in damages. There is currently no known cure for Pierce’s disease.

How does the glassy winged sharpshooter spread?

Its feeding method, along with its voracious appetite for so many different hosts, makes the glassy-winged sharpshooter a vector for the Xylella fastidiosa bacterium. Once it feeds on an infected plant, the sharpshooter carries the bacterium to the next plant and transmits the disease while feeding.

Are leafhoppers destructive?

What are Leafhoppers? Leaf Hoppers are a destructive species of pest known to suck-sap from plants and cause plant diseases such as sooty mold. While plant damage from a single Leafhopper is insignificant because they are so small, if there is a large outbreak of them feeding on your plants, they could be at risk.
