The spotted lanternfly, a non-native invasive pest, has become a serious threat to Ohio’s agriculture and ecosystems.
While its stunning appearance, featuring gray wings with black spots and vibrant red underwings, captures attention, this insect’s impact is far from beautiful. It feeds on over 100 plant species, including grapevines, hops, apples, and maple trees, posing risks to Ohio's economy and agricultural landscape.
Since its detection in Ohio in 2020, the spotted lanternfly has spread rapidly, leading to quarantines in 12 counties, with Franklin County being one of the hardest hit.
Experts from The Ohio State University’s College of Food, Agricultural, and Environmental Sciences (CFAES) are working to educate the public about the pest, urging community involvement in monitoring and managing the spread.
As the insect’s egg-laying season starts from late September to early October, the focus is on removing egg masses before winter. CFAES developed an egg scraper tool to help individuals actively combat the pest.
Ashley Leach, a CFAES entomologist, stresses the importance of removing egg masses to reduce the spotted lanternfly population.
The insect’s rapid spread in Ohio is exacerbated by a lack of natural predators and environmental stressors like drought. Its presence not only stresses plants but also leads to increased insect activity due to the sticky honeydew it excretes, attracting wasps and hornets.
Ohio’s agricultural sector, particularly crops like grapes and fruit trees, faces significant threats from the spotted lanternfly. Experts emphasize that while tools exist to manage the insect, ongoing efforts and adaptations in agricultural practices will be necessary to ensure the sustainability of affected crops.
As temperatures drop and freezing weather kills adult spotted lanternflies, overwintering eggs will lead to next year’s infestation, making vigilance crucial.
Recognizing the signs of the spotted lanternfly, including egg masses and plant damage, is key to managing this growing threat.
