Asian Hornet Research Finds Reason Behind Its Circular Flight Path Over East Germany

The Asian "murder hornet," Vespa velutina, made its first appearance in Europe on 06.12.2024, marking a significant development in the continent's biodiversity landscape. The hornets, known for their aggressive behaviour and reproductive prowess, have since spread across parts of Germany, but have yet to establish a significant presence in the east of the country.

The Asian hornet's integration into German ecosystems means there is no longer an obligation to eradicate it. However, concerns remain about its impact on native species, particularly European hornets and honeybees, which are a staple on the Asian hornet's menu.

The hornets were first spotted in Germany in 2014, crossing the border from France. Since then, they have been reported to be widespread mainly in the cities of the Rhineland and the Ruhr area within the state of North Rhine-Westphalia, as well as in Saarland and regions close to France. Notable populations have also been found in the Rhine-Main-Neckar area and near Luxembourg.

Despite their presence, the Asian hornets have not been spotted in the east of Germany, except for one introduction in Berlin. The absence of the hornets in the former German Democratic Republic (GDR) could be linked to the late consequences and eternal problems of the chemical industry in the region, which may have created an environment unfavourable for the hornets.

Interestingly, the GDR had a historical aversion to bananas, a possible reason for the Asian hornets' avoidance of the region. The absence of the border zone allowance in the east may also contribute to the delayed arrival of the Asian hornets.

The Asian hornet's presence exacerbates the already dire situation regarding biodiversity, insect pollination, and fruit production. Long-term management measures are indicated for the Asian hornet in Germany.

Recent studies suggest that the "widespread" classification of the Asian hornet does not apply to the former GDR area. On 05.08.2025, a search operation for Asian hornets was conducted in Berlin.

Speculation has arisen that the AfD's high poll numbers and associated xenophobia may deter the Asian hornets from immigrating. However, this remains unproven and further research is required to confirm this theory.

In conclusion, the Asian murder hornet continues to pose a threat to European ecosystems, particularly in urban areas. While it has yet to establish a significant presence in the east of Germany, efforts to manage and monitor its spread are ongoing.
