The spotted lanternfly, a destructive invasive pest with origins in southeast Asia, has made its way to Canada for the first time, marking its presence twelve years after its appearance in North America. The Canadian Food Inspection Agency (CFIA) confirmed the detection of this pest in Windsor, Ont., on Sept. 15.
Initially identified in Pennsylvania in 2014, the spotted lanternfly is notorious for its ability to harm and kill grapevines, posing a significant threat to the grape and wine industries. This pest is not selective in its feeding habits, as it can consume the sap of over 100 plant species, potentially impacting various crops, horticulture, forestry, residential areas, and public parks. Both nymphs and adults primarily target native hardwood and fruit trees, with a preference for the invasive tree-of-heaven and a tendency to feed on black walnut trees.
The Invasive Species Centre emphasized the potential widespread economic, ecological, and social repercussions if the spotted lanternfly is left unchecked. In response to the infestation, movement restrictions have been enforced to prevent the transportation of infested materials, and surveillance efforts are in place to assess the extent of the problem. The CFIA’s spotted lanternfly response framework guides the proactive measures being taken.
Colin Cassin, Executive Director of the Invasive Species Centre, encouraged the public to play a role in identifying and reporting invasive species like the spotted lanternfly early on. Following the “spot it, snap it, catch it, report it” protocol can aid in preventing the spread of this pest.
To help combat the spread of the spotted lanternfly, individuals are advised to check for egg masses, nymphs, or adult insects in outdoor items before leaving infested areas. It is recommended to wash vehicles thoroughly and avoid moving firewood from one location to another to prevent the inadvertent spread of these invasive insects.
