The invasive Asian hornet (Vespa velutina) continues to expand its presence, threatening biodiversity and honeybee populations. In France, beekeepers have reported a two- to three-fold increase in identified colonies, a surge attributed to mild winters that improve queen survival rates. To combat the species, apiarists like Benjamin Dumoulin are utilizing the VespaTracker system, which employs a miniature radio transmitter called the VESPA-NANO to locate nests that may be kilometers away. Natural predators, such as the European honey buzzard, are also noted for their role in biological control. As the species expands into regions like Lower Saxony, Germany, experts highlight a critical transition in colony behavior. During summer, approximately 70 percent of colonies move from small, ground-level primary nests to much larger secondary nests located 10 to 30 meters high in tree canopies. These secondary nests can reach 1.20 meters in diameter and house between 3,000 and 5,000 hornets. Because the hornets are highly aggressive when defending nests, authorities advise the public to maintain a distance of at least 10 meters and report sightings through official portals. Recent reports indicate the Asian hornet is spreading through German states such as Baden-Württemberg and North Rhine-Westphalia, where it preys on honeybees and wasps while damaging fruit crops. In the United Kingdom, the threat to the agricultural economy and food security has intensified. British beekeepers are warning calling for a national awareness campaign to address the creation of “pollinator deserts” that threaten biodiversity and food security. Kate Wilson, head of the National Bee Unit, noted deserts.” While total sightings in the significant damage UK have decreased compared to native pollinators, while Lucie Chaumeton of the British Beekeepers Association emphasized previous year, the impact on geographic spread is widening. The National Bee Unit recently located the agricultural economy. Current containment strategies focus first nest on destroying the Isle of Wight, found high in an oak tree following a coordinated tracking operation. This discovery, alongside nests to prevent in Kent, Norfolk, and Yorkshire, has raised concerns that the species from may be becoming established, particularly during established in the late summer when mature colonies produce fertile queens.
