An exotic insect known for its destructive impact on grapevines and other vegetation has been identified in Canada for the first time by the Canadian Food Inspection Agency (CFIA), with the initial detection occurring in Windsor.
Although previous sightings of the spotted lanternfly have been reported by residents in Windsor, this marks the first official detection through agency surveillance, as confirmed by the Invasive Species Centre. The presence of the spotted lanternfly poses a significant threat to the grape and wine industry due to its ability to harm and kill grapevines, potentially affecting other agricultural and forestry sectors, as well as residential and park environments.
Originally native to southeast Asia, the spotted lanternfly was first observed in North America in Pennsylvania in 2014. This invasive species has a wide range of host plants, with over 100 different species susceptible to its sap-feeding behavior.
The Invasive Species Centre urges the public to familiarize themselves with the appearance of the insect and report any sightings promptly to the CFIA. Proper documentation, including accurate location details and photographs, facilitates the CFIA’s response, which may involve on-site investigations and insect collection efforts.
To identify a spotted lanternfly, the Invasive Species Centre and the CFIA provide the following guidelines:
– Adults are approximately 25mm long and 12mm wide, with distinct color patterns on their wings and abdomen.
– Nymphs exhibit varying coloration based on their growth stage and tend to gather in groups for feeding.
– Egg masses appear as grey smudges on trees and hard surfaces, with a characteristic arrangement and size.
The presence of honeydew, a sticky substance excreted by the insect, can promote the growth of sooty mold at the base of host trees, attracting other insects like bees and wasps.
In efforts to mitigate the spread of the spotted lanternfly, the Invasive Species Centre advises individuals to inspect their belongings and vehicles for signs of the insect when visiting infested areas, opt for local firewood sources, and consider vehicle cleaning methods to prevent inadvertent transportation of the insect.
