Day 7 - Economic, Human & Ecological Risk - Asian Hornet Week
This is the final day for Asian Hornet Week, 2026. We have covered a great deal of information about this pest and the potential harm it creates to our delicate ecosystems.
Some of the highlights are detailed here:
Threat to Honeybees and Pollinators
• Devastating predation: Hornets hover outside beehives in a hunting behaviour known as "hawking," catching bees mid-flight to feed their developing larvae.
• Hive paralysis: A single colony can consume thousands of bees. Under siege, bees refuse to leave the hive to forage, leading to starvation and collapsed colonies.
• Lack of defence: Unlike native Asian honeybees, European honeybees have not evolved effective defence mechanisms against this specific hornet.
• Wider ecological impact: They do not eat only honeybees; research shows they hunt a wide variety of beneficial insects, including hoverflies, butterflies, and other social wasps, which threatens overall biodiversity and plant pollination.
Remember: Only around 38% of Vespa velutina’s diet consists of honeybees – 62% is all the other insects & invertebrates.
Honeybee colonies are “easy” prey – it is like an open larder for them.
Economic and Agricultural Damage
• Crop loss: By reducing the number of vital pollinators, the hornets can negatively impact the quantity and quality of agricultural and fruit crop yields.
• Beekeeping disruption: They severely damage local honey production and force beekeepers to spend significant time, effort, and money on protective measures.
Human Health Risks
• Aggressive defence: While not overly aggressive away from their nests, they defend large secondary nests fiercely when disturbed.
• Stings and anaphylaxis: Their venom contains toxic and allergenic components. In areas where they have proliferated heavily in Europe, they have become a leading cause of severe allergic reactions (anaphylaxis) from stings.
This is not an exclusive issue just for beekeepers; it will affect multiple areas of society, from agriculturalists to amateur gardeners, basically anyone working outdoors.
What can you do to help fight this predator?
The answer to this is simple:
• Tell your friends and relations
• Learn how to identify them
• Publicise this to your clubs and social events
• Publicise in social and conventional media outlets
• Become a volunteer prepared to house a monitoring station(s) in your garden or land
