Leafhoppers are vectors of bacterial and viral plant pathogens. These pathogens reduce grapes and fruit crops. Over 5000 cultivars of Vinifera grapes are grown worldwide, in the USA this is valued at $2.9 billion, making it the highest value fruit crop in the US. At present worldwide wine grape production is over 8,000,000 ha, the extraction of trans-resveratrol and trans-e-viniferin from grapevine has an estimated global economic value >$30 billion. Other fruits impacted include Stone Fruits (US. Value over $1.3 billion, 2007, USDA, ARS). H.vitripennis from field, colonies, or as gDNA are available, Hunter lab, FL.
