An Asian hornet has been discovered in Denmark for the first time, raising concerns about its potential impact on native species and fruit growers. The Danish Beekeepers Association confirmed that a specimen was captured in Kerteminde, located on the northeastern part of Funen.
This invasive species, not native to Denmark, poses a threat to local ecosystems and agricultural activities. Rune Havgaard Sørensen, head of secretariat at the beekeepers association, highlighted the damage the Asian hornet has inflicted on fruit crops in Southern Europe. The hornet’s propensity to attack ripe fruits and its rapid multiplication make it a significant problem for farmers.
The Asian hornet’s diet consists of various insects, including honeybees and bumblebees, making them particularly vulnerable. According to Havgaard Sørensen, a single nest of Asian hornets can consume up to 11 kilograms of insects annually, with a specialization in easily captured insects like honeybees and bumblebees frequenting hives.
Originating from Asia, the Asian hornet’s presence in Europe dates back to 2005, when it was first detected near Bordeaux, France. The Environmental Protection Agency suggests the species likely arrived via ship from China. Since then, it has spread across France, Spain, Portugal, parts of Northern Italy, and Belgium. Isolated sightings have also been reported in the United Kingdom, and the species has been found as far north as Hamburg, Germany.
In response to the discovery, the Danish Beekeepers Association has deployed traps in the vicinity of the capture site to determine if the hornet was a solitary individual or part of a larger nest. The association aims to locate and eradicate any nests before the hornets can reproduce and spread further.
The Asian hornet, measuring two to three centimeters in length, is identifiable by its distinctive physical characteristics. These include two prominent yellow bands on its abdomen, a black head and thorax, and yellow legs.
The public is urged to report any suspected sightings of Asian hornets through the website arter.dk. Alternatively, individuals can contact the Danish Beekeepers Association and provide photographic or video evidence of their observation.
