The Invasive Hornet Threat: A Call to Action for Environmentalists and Beekeepers

The Invasive Hornet Threat: A Call to Action for Environmentalists and Beekeepers

In recent developments that have stirred the environmental and beekeeping communities, a large invasive hornet queen was captured in Jasper County, South Carolina, on March 14. This event marks the second sighting of the yellow-legged hornet in the state, a species posing a grave threat to our already vulnerable honeybee populations and, by extension, the broader ecosystem.

The Emerging Threat

• The yellow-legged hornet, first spotted in South Carolina in November 2023, has been identified as a formidable predator of honeybees.
• These hornets exacerbate existing challenges for bees, including pesticide exposure, habitat loss, and climate change impacts.
• Beyond bees, they threaten crop pollination, crucial for our food supply.
• Interestingly, these hornets' nests are substantial and often located in trees or man-made structures, yet they generally do not pose a direct threat to humans unless provoked.

The Significance of the Recent Capture

• The capture of a queen is particularly significant as it indicates proactive measures to prevent the establishment of new colonies.
• Originating from Southeast Asia, the yellow-legged hornet has expanded its presence to Europe and the Middle East, with the first U.S. sighting in Savannah, Georgia.

The Response

• Clemson University and the Department of Agriculture are at the forefront of monitoring and trapping efforts.
• The community is urged to report sightings of these large hornets or their nests to aid in eradication efforts.

FAQs

1. What distinguishes the yellow-legged hornet from native species? The yellow-legged hornet is larger than most native species and poses a significant risk to honeybees.

2. How can I help? Report any sightings of large hornets or nests to Clemson University's Department of Plant Industry.

3. Why is the capture of a queen hornet significant? Preventing the establishment of a new colony mitigates the threat to local bee populations and agriculture.

4. What are the broader implications of these hornets establishing in the U.S.? Their presence could devastate beekeeping operations and disrupt the natural pollination processes critical for many crops.

 

• A large invasive hornet, specifically a queen, was captured in Jasper County, South Carolina, on March 14, marking the second yellow-legged hornet found in the state.
• The first yellow-legged hornet in South Carolina was found on Nov. 9, 2023, after Clemson University set traps in the Lowcountry.
• These hornets pose a threat to honeybees by attacking them, further exacerbating their decline due to pesticides, drought, habitat destruction, nutrition deficits, air pollution, and global warming.
• They can disrupt crop pollination, with the U.S. Department of Agriculture highlighting their threat.
• The hornets usually don't attack humans unless their nests are disturbed. Their nests are large, above ground, and often in trees or on structures.
• Capturing a queen is significant as it prevents the establishment of a new nest in the area.
• The yellow-legged hornet originates from Southeast Asia and has spread to the Middle East and Europe, with the first U.S. sighting in Savannah, Georgia.
• They resemble several native insects but are identifiable by their larger size. Clemson is urging the public to report sightings.
• Plant Industry scientists are conducting year-round trapping to eradicate any found nests.
• The establishment of this hornet in the U.S. is seen as a significant threat to beekeeping.
