2022 Adult Spotted Lanternfly Status in PA Vineyards: November 18

The Penn State Grape and Wine Team sends a weekly survey to learn more about the magnitude and severity of adult spotted lanternfly (SLF) populations throughout Pennsylvania vineyards.  Thirty-three growers reported the absence of adult SLF in their vineyards, while seven growers still reported the presence of adult SLF in their vineyards between November 11 to November 17, 2022.

Below is a map showing counties with at least one vineyard that reported the presence of adult SLF. At least one vineyard in Adams, Allegheny, Armstrong, Berks, Bucks, Butler, Centre, Chester, Cumberland, Erie, Franklin, Indiana, Lancaster, Lehigh, Luzerne, Lycoming,  Montgomery, Northumberland, Perry, Snyder, Susquehanna, Westmoreland, and York counties reported adult SLF absence.

This is our last summary for the 2022 season. We thank all stakeholders for their participation in this survey! It was very informative for our team to receive weekly SLF updates from our stakeholders; we hope it was also informative for stakeholders to receive these reports. We look forward to implementing similar surveys on SLF patterns in vineyards throughout the 2023 growing season—stay tuned!

Please see the Spotted Lanternfly Management in Vineyards fact sheet for information about SLF management in vineyards.

Please see The Penn State Extension Grape and Wine Team's website for previous reports of adult SLF trends in Pennsylvania vineyards in the 2022 vintage.
