Interpretive Summary:

Technical Abstract: Researchers at the USDA-ARS in Wapato, WA have collaborated with scientists at Washington State University to identify several beneficial biological controls that may be key to long term management of cherry X-disease. X-disease has recently emerged as a major threat to cherry, peach, and nectarine production in the Pacific Northwest, producing small, bitter fruit. This disease is caused by a bacterium called Phytoplasma pruni, that is spread by insects called leafhoppers. There is no way to cure trees once infected, so the only management options are to suppress populations of the insect vectors or remove diseased trees and orchards. The researchers found that leafhopper vectors are often attacked by parasitic flies and wasps. Identification of these parasites will allow the researchers to develop strategies to implement biological controls in the fight against X-disease, leading to reduced use of insecticides.
