Citizen Involvement Credited for Reduction in Lanternfly Numbers
New York City has witnessed a substantial decrease in its lanternfly population this year, thanks to the concerted efforts of its residents. Entomologists have praised the public for playing a crucial role in curbing the spread of these invasive insects.
The lanternfly, originally from Asia, made its way to New York City in 2020. Since then, bug hunters and environmentalists have been actively working to halt its expansion. The species is known for its high reproductive rate, which can pose severe ecological threats in affected states.
High reproductive rate and threats
Brian Eshenaur, a senior associate for NYS Integrated Pest Management at Cornell University, explained the reproductive capabilities of the female lanternfly. “Female lanternflies can lay 30 to 40 eggs at once and three times over the summer and fall,” Eshenaur told the New York Post. This rapid reproduction can lead to significant infestations if left unchecked.
Celebrity involvement and public impact
Efforts to combat the lanternfly have garnered widespread attention, even seeing celebrities like Leonardo DiCaprio getting involved. “I have to think we are making an impact,” Eshenaur said, emphasizing the collective efforts of the community.
While human intervention has been pivotal, other factors have also contributed to the decline in lanternfly numbers. More natural predators have started to target the lanternfly, and specific types of wasps are beginning to consume the bug. Additionally, the tree species that lanternflies feed on no longer provide the same nutritional value as before, making it harder for the insects to thrive.
“I think that everything humans have been doing [to help eradicate lanternflies] is important because there is no silver bullet,” Eshenaur remarked.
Impact on daily life
Despite their reduced numbers, lanternflies can still be found on their preferred host plants throughout the city. “They are still present and can be found on their favorite host plants . . . throughout the city,” Eshenaur said. “But they are not at the same levels, so the average pedestrian will not interact with them to the degree they did for the last couple of years.”
The lanternfly’s impact has not been limited to New York. In 2019, the insects caused $550 million in damages to crops in Pennsylvania by drilling into trees and plants to feed on sap. This highlights the importance of continued vigilance and community efforts in managing the pest.
A call to action
Eshenaur concluded with an encouraging message to New Yorkers: “Just keep up the good work, New York.”
This significant reduction in lanternfly numbers serves as a testament to the power of collective action and the importance of public awareness in tackling environmental challenges.
