Help Wanted Now To Track the Spread of Prolific Spotted Lanternfly Pest

Posted by Growing Produce Staff|October 21, 2023

The dreaded spotted lanternfly is continuing to spread across parts of the country. Stopping the spread of this invasive insect is a tall order. Penn State Extension Grape and Wine Team is calling on those who own, operate, or manage a farm, vineyard, or winery in the Mid-Atlantic region to participate in a survey that aims to track the spread and severity of nymph and adult spotted lanternfly populations during the 2023 season.

Participation is critical to help thwart this pest that attacks the woody tissue on grapes, apples, cherries, peaches, pines, and many other species of trees and shrubs. The spotted lanternfly, native to China, has a voracious appetite. It’s been on the march around the U.S. since first being detected during fall 2014 in eastern Pennsylvania.
