Spotted Lanternfly inCentre County, PASPOTTED LANTERNFLY GUIDE
Centre County is home to Penn State University β one of the largest universities in the United States β making it both one of the most important SLF research hubs in the nation and one of the most challenging infestation management sites. Confirmed in 2019, SLF populations have become heavily established across the Nittany Valley, from the Penn State campus in University Park through the surrounding agricultural and forested landscape. The I-99 corridor connecting State College to the broader interstate network is a primary freight-mediated spread vector, and the enormous volume of student, faculty, and visitor traffic to Penn State creates continuous SLF introduction and dispersal risk. Penn State Extension runs some of the most active SLF public education and monitoring programs in Pennsylvania from this county.
