The Northeastern IPM Center promotes integrated pest management for reducing risks to human health and the environment. Penn State Extension: Spotted Lanternfly ( /spotted-lanternfly)-Penn State was the lead institution on the 2018 Northeastern IPM Center-funded working group that laid the groundwork for the USDA SCRI grant, and the grant’s project director, Julie Urban, is an associate research professor at Penn State. Stop SLF ( USDA SCRI-funded project to research and develop control methods for spotted lanternfly, maintained by the Northeastern IPM Center. Also available to view is the recording of Spotted Lanternfly 101, a presentation and Q&A session held the week before the summit and intended to provide attendees with foundational SLF knowledge key to deriving maximum benefit from the summit. Visit to watch the summit presentations. The 2021 Spotted Lanternfly Summit was held virtually over the course of three full days, featuring presentations on new research, extension, and communications efforts and outreach to stakeholders and industry. These counties are not completely infested but have some municipalities with known infestations. ![]() The counties added were Cambria, Cameron, Franklin, Lackawanna, Montour, Pike, Wayne, and Westmoreland. Pennsylvania added eight more counties to its quarantine, painting a swath westward across the whole state. Several New Jersey counties were added to the map, reflecting that most of the state is now infested. In February, Virginia expanded its quarantine area by two more counties, Warren and Clarke. There also were dead individuals discovered in three North Carolina counties. January 2021īerkley County, in western Maryland, was added to the map.

Also added was Mineral County in West Virginia.Īlso this month, Brian Walsh, a Penn State Extension horticulture educator in Berks County, PA, presented a webinar- Spotted Lanternfly: Impacts and Strategies for Ornamental Plants-a useful overview of this pest and its implications. The map was updated to include Tompkins, Orange, and Rockland Counties, as well as Staten Island, Brooklyn, and Queens in the New York metropolitan area. In New York, large infestations were found in Orangeburg, Port Jervis, and Staten Island. The dead adults arrived on freight or trucks from infested areas. Once 2021 arrived, a springtime removal of trees in the vicinity was conducted to stop any undiscovered egg masses from hatching.ĭead adults were found in Michigan, but there remain no known live populations. Adults and egg masses were discovered around the parking area of a student apartment complex. In November, a population was discovered in Ithaca, NY, by an entomology undergraduate student. The SLF map maintained by the New York State IPM Program was updated to reflect infestations in these Connecticut and Ohio counties, in addition to Washington County in Maryland. Live populations were discovered in New Canaan and Greenwich, Connecticut, and in Jefferson County, Ohio, along the Ohio River and adjacent to the known western Pennsylvania population in Beaver County. The egg masses were empty and presumably had hatched in Pennsylvania, not in Maine. Both had been transported in on plant material that originated in Pennsylvania. Last October, two dead SLF individuals were found in Massachusetts and egg masses were found in Maine. Since fall of 2020, there have been a number of finds-not always indicating established populations, but generally illustrating the pest’s penchant for spreading, particularly with inadvertent human assistance. Although efforts to develop management techniques to control the invasive spotted lanternfly (SLF) are well underway-including current work funded by a USDA Specialty Crop Research Initiative grant awarded in 2019-as expected, the pest’s presence and influence have continued to spread. ![]()
