Asian Hornet Invasion Spreads To Northern Germany

Asian Hornet Invasion Spreads To Northern Germany

There are now more than 1,000 of them in Germany, but the species has disappeared from the north of the country in recent years, according to a new study by the German Academy of Sciences and Humanities. Sources: 6

Asian hornets (Vespa velutina nigrithorax) were collected in Hamburg, a city about the same latitude as Manchester, UK. Sources: 6

The scientists mapped a similar potential invasion of the UK using data on where detailed observations of destruction took place, and predicted that the likelihood of their nests thriving in it is low. Professor Michael O’Neill, from the university’s Department of Ecology and Evolutionary Biology, said: “Our research shows that this predator has invaded and colonised Britain and is rapidly spreading to new invasion areas. Sources: 5

Asian hornets, which have already invaded parts of southern and central Europe, are known to eat many insects, including honeybees and other livestock, and pose a potential threat to beekeeping and even ecosystems. Asian hornets hovered over honeybee hives and killed them as they returned from foraging. Sources: 2, 5

The first specimen was caught in southern and western France in 2005 and began to spread rapidly. The following year it invaded parts of southern and central Europe as well as the United States and Canada. Sources: 2

The distribution of the species has spread in France with an estimated rate of invasion of about 78 km per year. She has also performed in the United States, Canada, Australia, New Zealand, South Korea, Japan and South Africa. The distribution of the species took place with an estimated rate of invasion of about 80 km / year in Europe and the USA. Since 2005, the species has spread to Germany, Austria, Belgium, France, Switzerland, Germany and Austria. Sources: 2, 6

Whether or not the Asian hornets collected belong to an already settled population is not yet clear, according to the research team. Although other models suggest that the Hamburg area is not suitable for the species today, the new find coincides with the hypothesis that they spread more rapidly in northern Germany and the south of the country than previously known. The rapid invasion of this species was not necessarily caused by human-mediated propagation. However, it is not unusual for a species that can spread rapidly on its own. Sources: 4, 6

V – velutina nigrithorax preyed on honeybees, which harmed beekeeping, the research team said. They also pose a potential threat to human activities as they nest in urban areas. Asian hornets, known for their aggressive behaviour towards humans, have a negative impact on ecosystems in general, contributing to an increase in the number of wild insects they pray to during their activity, and have also contributed to a decline in honeybee populations in Germany and other countries. Sources: 4

Professor Keeling and his colleagues outlined a similar potential invasion of Britain by using data on Asian hornet populations in England, Wales, Scotland and Northern Ireland, as well as detailed observations of destruction. Sources: 7

Asian hornets, scientifically known as Vespa velutina nigrothorax, hunt honeybees by hovering over them, waiting to catch and kill those who return to forage. They also eat the larvae of other bee species, such as the honeybee, and later in the summer, hornet attacks on bees cause the hives to be completely destroyed within a few days. If you are vigilant and able to identify bee colonies, you can stop the invasion of Asian hornets into Britain and Northern Ireland in early summer. Sources: 1, 3, 7

Asian hornets were first discovered in the French Southwest in 2005, and legends quickly emerged that they had been imported from China with a supply of cooking pots. As the threat spreads rapidly, up to 100 km per year, and new nests are discovered every year in different parts of Western Europe, it is not known where they will strike next. The Asian hornet has spread to Germany, the Netherlands, Austria, Belgium, Denmark, Norway, Sweden, Finland, Switzerland and the Czech Republic. Sources: 3

The research team simulated and mapped how the estimated Asian hornets would spread over a 25-year period from the location of the first verified nest, and simulated their spread across the country, starting with sites with first verified nests, before the predicted invasion. They used data from the Andernos – les – bain region in France, where there is a large number of honeybee colonies, as well as detailed observations in Germany. Combating the problem is about early detection and eradication, “says Dr. Peter Budge, researcher in the Department of Ecology and Evolutionary Biology at the Max Planck Institute for Ornithology. Sources: 0
