The spotted lanternfly (SLF) is a sap-feeding insect native to Asia that feeds on more than 65 plant species and is projected to become a serious pest of specialty crops including grapes, tree fruit, ornamentals, and hardwoods. The goals for this project are to develop efficacious tactics for managing the invasive SLF, on vulnerable specialty crops to reduce the risk of widespread, catastrophic damage and to develop strategies for long-term SLF management.
