Researchers at Cornell University say if left unchecked, the spotted lanternfly could cause millions of dollars in losses to the state’s thriving grape and wine industry. The pest feeds on the sap of grapevines and leaves a residue that promotes mold growth impacting the quality and quantity of grapes.
Researchers used data from the Lake Erie and Finger Lakes regions and estimate losses could reach nearly $9 million by the third year of infestation.
In 2022, the grape industry generated $15 billion to the state's economy. The Finger Lakes saw its first spotted lanternfly last summer but reports no ill effects so far. Researchers say preparedness and continued research are essential to controlling the pest.
