Southeast Pennsylvania has a thriving grape and wine industry that is being jeopardized by the Spotted Lanternfly (SLF). The Spotted Lanternfly, Lycorma delicatula, is an invasive planthopper native to China, India, and southeast Asia. It was first discovered in Berks County, Pennsylvania and has spread to 16 other counties in the southeast portion of Pennsylvania. It is thought to have been introduced on wooden pallets from South Korea. This SLF is a threat to agricultural crops such as grape, hops, apples and other fruit. Vineyards are especially susceptible to SLF infestations, resulting in damage to the plants and a drastic reduction in brix levels of the grapes. With no natural enemies, the SLF is rapidly increasing its territory.
