🐞 SLF Populations Are Growing — Stay Vigilant! 🚨🍇
Spotted lanternfly (Lycorma delicatula, SLF) continues to spread across NY, now confirmed in 30 counties and moving closer to our region. While not here yet, populations are expanding near Syracuse.
If you spot SLF, report it to iMapInvasives reportslf.com. 📸
SLF love tree-of-heaven (invasive), orchard and vineyard plants, maples, willows, and walnut — but not conifers. Native predators and new biocontrol research offer hope, including a promising parasitoid wasp now under USDA review, and studies of how native milkweed plants could be used as a management tool.
Stay alert, and help protect our forests and vineyards! 🍇🌳
