The spotted lanternfly, an invasive species native to Asia, is causing concern in Tennessee as its presence and damage to crops and native plants increase. This insect, which was first spotted in the state in 2023, has now been found in several counties, including Hamilton, Davidson, and Knox. While it poses no threat to humans or animals, its impact on plants is significant.
Midhula Gireesh, an assistant professor at the University of Tennessee, emphasizes that the lanternfly's primary concern is its harmful effect on plants. The insects feed on plants, depleting their resources and contributing to sooty mold, which can cover plants and prevent them from feeding. This can lead to significant damage to crops and native plant species.
DeAnna Beasley, a professor at the University of Tennessee at Chattanooga, highlights the unintentional spread of invasive species. She explains that these species often hitch a ride on materials we want, such as shipping containers or vehicles, and are then introduced to new habitats where they can cause destruction. This is how the spotted lanternfly likely arrived in the United States.
Cindy Bilbrey, the state Entomologist, notes that the lanternfly has been in Tennessee for several years, with the first confirmed finds in 2023. The insects have been found in major metro areas, including Davidson and Knox counties, and closer to home in Hamilton County. State officials are urging residents to report sightings, especially if it's a first detection in an area.
The Tennessee Department of Agriculture advises that if spotted lanternflies are seen, they should be killed, including their eggs. Egg masses can be found in various places, not just on trees, and can be removed using a soapy water solution and an old credit card. This proactive approach is crucial to preventing the spread of the lanternfly and minimizing its impact on the local ecosystem.
While there is no reason for panic, the threat to plants is a serious concern. The spotted lanternfly's ability to feed on plants and contribute to sooty mold can lead to significant damage to crops and native plant species. As the insect continues to spread, it is essential for residents and officials to remain vigilant and take appropriate measures to control its population and protect the state's natural resources.
