New York tackles spotted lanternfly threat

By Blake Jackson

The New York State Department of Agriculture and Markets has reported new sightings of the Spotted Lanternfly (SLF) in several locations across the state. SLF is an invasive insect that feeds on over 100 plant species, including crops critical to New York’s agricultural industry, such as grapes. The Department is urging residents in affected upstate counties, including Albany, Schenectady, Ontario, and Seneca, to report sightings and remove egg masses to help control the spread of the insect.

“We have been working with our partners for years to contain SLF and minimize the spread of this invasive species, which can cause extensive damage to plants and crops that are critical to New York’s agricultural economy. We are incredibly grateful for the help New Yorkers have provided in the last few years and urge residents to continue eliminating egg masses by scraping them off trees, structures and outdoor furnishings now that the cold weather is here. We’re optimistic that through education and continued collaboration with our partners and the public, we will be able to manage SLF and mitigate the impact to the grape growing industry in the years to come,” said State Agriculture Commissioner Richard A. Ball.

SLF, first detected in Pennsylvania in 2014, has since spread to 18 states, including New York, where it was first spotted in 2020. The insect has now been found in new areas such as Geneva, Romulus, Schenectady, and Cohoes. Although adult SLF are no longer active in December, the public is advised to remain vigilant for egg masses and report any sightings in the spring.

To help slow the spread, the Department recommends taking a photo of any SLF sighted, collecting a sample, and reporting it online. Travelers leaving infested areas should inspect vehicles and belongings for egg masses and destroy them by scraping. SLF lays its eggs on various surfaces like vehicles, furniture, and firewood, making it crucial to check these areas regularly.

SLF causes significant harm to plants by stressing them, making them more susceptible to diseases. Its excretion of honeydew can lead to mold growth, further damaging crops. Without control, SLF could potentially cost New York's agricultural industry millions, especially in the grape sector. To mitigate this, state agencies continue to collaborate with partners and the public to manage and limit the insect's impact. For more information, visit the Department's website.
