An invasive insect that poses a threat to grapevines and various crops and trees has been found in Canada for the first time, identified by the Canadian Food Inspection Agency (CFIA). The initial detection occurred in Windsor.
Previous sightings of the spotted lanternfly in Windsor have been reported by residents, as noted by a non-profit organization dedicated to preventing the spread of invasive species. However, this recent detection marks the first time the insect has been officially recognized through an agency survey conducted by the Invasive Species Centre.
The spotted lanternfly is notorious for causing harm to grapevines, which could result in significant consequences for the grape and wine industry, according to the centre’s news release. It also has the potential to impact other agricultural sectors, horticulture, forestry, residential areas, and community parks. If left unchecked, the spread of the spotted lanternfly could lead to broad economic, ecological, and social repercussions.
Originally native to southeast Asia, the spotted lanternfly was initially detected in North America in Pennsylvania back in 2014. This insect has a wide range of host plants, feeding on the sap of over 100 different species.
The Invasive Species Centre is urging the public to familiarize themselves with the appearance of the insect. Individuals who spot the fly or its eggs are encouraged to take photos, secure the fly or eggs in a sealable container, and report the finding to the CFIA promptly. Effective reporting should include accurate location details and clear images of the insect. The CFIA will respond to reports of the spotted lanternfly and implement appropriate measures, such as conducting site surveys and collecting specimens.
To aid in identification, the Invasive Species Centre and the CFIA have shared several tips for recognizing the spotted lanternfly. These tips include descriptions of the adult flies, nymphs, and eggs, along with details on their appearance, behavior, and seasonal activity patterns.
The spotted lanternfly also leaves a sticky substance called honeydew at the base of host trees, which can lead to the growth of sooty mold and attract bees and wasps.
In efforts to curb the spread of the insect, the Invasive Species Centre advises individuals to thoroughly check their vehicles and outdoor items for any signs of spotted lanternfly when visiting areas known to be infested. Additionally, they recommend avoiding the movement of firewood and instead purchasing locally sourced firewood to prevent the spread of this invasive species.
