A working group has formed to address the spotted lanternfly (SLF, Latin name Lycorma delicatula), an invasive plant hopper native to China, Vietnam, and India. The spotted lanternfly was confirmed in Pennsylvania in September 2014. Funding was provided by the Northeastern IPM Center in the summer of 2018. The working group met several times and, with Penn State as the lead, submitted a pre-proposal to the USDA-NIFA Specialty Crop Research Initiative in December 2018. Although the initial effort of the working group is completed, the collaborations are continuing.
