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.
In honor of New York Invasive Species Awareness Week, the New York Invasive Species Research Institute is hosting a special spotted lanternfly webinar. Please join on Tuesday, July 9 from 9 am to 10:30 am for presentations on the latest spotted lanternfly (Lycorma delicatula) research.
Watch the recordings of our webinar series about spotted lanternfly. Each of the four webinars covers a different set of susceptible crops. View the recordings.
