Predilections of a destructive pest
Benjamin Rohr (Master of Environmental Studies ‘20—expected) is embarking on his capstone project to culminate his degree. The premise of his experiment is straightforward: to determine the types of trees the lanternfly prefers beyond its known affinity for ailanthus. The bugs, which don’t fly but can hop 20 meters or more in a go, were first seen in 2014 in Berks County, Pennsylvania, and quickly extended their range. They’re known to feed on 70 species of tree and vine, 30 of which occur in Pennsylvania.
