The California wine industry is on high alert after discovering invasive insect eggs in the state. The Asian spotted lanternfly, known for feeding on grapes, was found in an art shipment from New York, raising concerns for the entire winegrape industry in California.
The California Association of Winegrape Growers (CAWG) has launched a new website to raise awareness of this threat and urge residents to be vigilant. CAWG President Natalie Collins emphasized the importance of recognizing and reporting any sightings of the spotted lanternfly to prevent further spread.
The spotted lanternfly poses a serious threat to wineries by feeding on grapevine sap and causing stress to plants, potentially leading to plant death. These pests are easily identified by their distinctive appearance and are most active from July to November.
CAWG warns that the eggs of spotted lanternflies are often transported unknowingly, resembling mud cakes, and can be found in trailers, RVs, semi-trucks, and containers. It is crucial to report any sightings of these pests to the California Department of Food and Agriculture (CDFA).
In a recent incident, egg masses were discovered in an art shipment inspected by California’s Truckee Border Protection Station. After extensive inspection and cleaning, the eggs were destroyed to prevent further spread of the invasive species.
Although first sighted in Pennsylvania in 2014, the spotted lanternfly is a new species to North America. Researchers predict a potential arrival in California’s grape-producing counties by 2027, highlighting the need for proactive measures to protect the state’s wine industry.
