NEW PEST POSES THREAT TO WINE INDUSTRY: SPOTTED LANTERNFLY EGG MASSES INTERCEPTED IN CALIFORNIA

By Miriam Raftery
 
June 17, 2024 (Sacramento) – The California Association of Winegrape Growers (CAWG) is bringing attention to the discovery of 41 Spotted Lanternfly (SLF) egg masses on a shipment of artwork from New York and destined for Sonoma County. 
 
“The invasive pest has the potential to affect the entire winegrape industry,” a press release from CAWG states.
 
The egg masses were intercepted at the Truckee Border Protection Station in late March, the first-ever finding of SLF egg masses in California. If other SLF egg masses have arrived in California undetected, they may produce adults in the coming weeks, with peak populations expected in late summer or early fall.
