The spotted lanternfly, a destructive invasive pest known to harm various plant species, has been detected in Canada for the first time, twelve years after its initial appearance in North America. Originally native to southeast Asia, this insect was recently found in Windsor, Ont., on September 15, as confirmed by the Canadian Food Inspection Agency (CFIA).
This pest, first observed on the continent in Pennsylvania in 2014, poses a significant threat to agro-based industries, particularly the grape and wine sectors, due to its ability to damage and kill grapevines. However, the spotted lanternfly is not limited to grapes; it can also feed on over 100 different plant species, affecting crops, horticulture, forestry, residential areas, and public parks. The insect primarily targets native hardwood and fruit trees, with a preference for the invasive tree-of-heaven and black walnut trees.
In a press release, the Invasive Species Centre highlighted the potential widespread economic, ecological, and social impacts of the spotted lanternfly if left unchecked. Consequently, movement restrictions have been enforced to prevent the spread of infested materials, including plants. Surveillance efforts are underway in the surrounding area to evaluate the extent of infestations, following the CFIA’s response framework for dealing with the spotted lanternfly.
Colin Cassin, Executive Director of the Invasive Species Centre, emphasized the importance of early detection and reporting of invasive species like the spotted lanternfly. To aid in prevention, individuals are encouraged to follow the “spot it, snap it, catch it, report it” protocol:
Spot it: Familiarize yourself with the various life stages of the insect.
Snap it: Take photos or videos of suspected spotted lanternfly sightings.
Catch it: Secure the insect or egg masses in a sealable container.
Report it: Immediately report any sightings of spotted lanternflies to the CFIA, providing accurate locations and images for swift action.
Additionally, to curb the spread of these invasive pests, it is crucial to inspect vehicles and outdoor items for egg masses before leaving potentially infested areas. Utilizing a high-pressure car wash on vehicles and buying and burning firewood locally are recommended steps to prevent further proliferation of the spotted lanternfly.
