A study from Cornell University researchers warns of potentially significant economic losses to New York's grape industry from the invasive spotted lanternfly.
The research estimates losses could reach $8.8 million annually within three years of a major infestation.
Using data from the Lake Erie and Finger Lakes regions, key grape-producing areas in New York, the study projects losses of $1.5 million in the first year, $4 million in the second, and $8.8 million in the third.
These figures are based on observed impacts in Pennsylvania, where the spotted lanternfly first appeared in 2014.
"It might seem like spotted lanternfly is not as big a problem as it seemed a few years ago," said Allan Pinto, agricultural economist with NYSIPM and lead author of the study. "This reminds people: It might not be bad if you do something, but if you don’t, it could be really bad.”
“It’s important to have something like this so that growers can understand that they need to take spotted lanternfly seriously,” said Brian Eshenaur, invasive species coordinator and senior extension associate with NYSIPM. “It’s also important for the industry overall, to understand the impacts if nothing is done.”
The study provides growers with information on the spotted lanternfly's lifecycle and best practices for monitoring and control. It also offers a methodology for other states to estimate potential losses.
Researchers at Cornell are continuing their efforts to help New York growers combat the pest. The next step is to provide cost projections for various prevention and treatment strategies, enabling growers to make informed decisions.
