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.

Preliminary findings of a Penn State-led study on spotted lanternfly management indicate that foliar application of an insecticide could be effective in reducing satellite populations of the pest.
Beginning in late May, a remote section of Blue Marsh Lake property in Berks County, Pennsylvania, will be the site of a research project focusing on biological control of the spotted lanternfly. Learn more about the research and read the FAQs about the project on the Penn State Extension website.
