Eric Clifton of Cornell University collects data on invasive spotted lanternfly at a vineyard

USGS researchers at the USGS New York Cooperative Fish and Wildlife Research Unit are investigating invasive spotted lanternfly in Pennsylvania, New Jersey, and New York. Vineyards are especially vulnerable to invasive spotted lanternfly, but tree farms, fruit farms, and nurseries are also at risk of damage. Invasive spotted lanternflies expel a sticky ‘honeydew’ and sooty mold when feeding, reducing fruit yields on grapes, fruit trees, and hops. Prevention, early detection, and rapid response are the most cost-effective strategies for reducing or preventing negative impacts to vineyards, tree and fruit farms, and nurseries across the U.S.
