The nest was found at the beginning of November at a height of 25 meters in the crown of an oak tree. The Office for Hunting, Nature and Fisheries then notified the beekeepers in the immediate vicinity of the discovery and the local beekeeping associations and asked for increased monitoring of their bees. Two beekeepers later found the nest.
The horn of Asia was brought into Europe through the south of France. It is no more dangerous to humans than native hornets or honey bees. Asian hornets hunt insects. Their hunting behavior can affect honey bees and destroy colonies.
It is hoped that the Asian hornet will continue to spread in the canton of St.Gallen. To slow this down, their nests are removed. Reports of nests are important, but also of suspiciously large antlers. In the current season the nests are clearly visible. Beekeepers are encouraged to monitor their hives. For reports see below www.asiatischehornisse.ch a Switzerland-wide platform is available.
In addition to the Asian hornet, other introduced species such as the quagga mussel, tiger mosquito, slider-eared turtle and others are spreading in the canton of St.Gallen. The Neobiota department in the Office of Hunting, Nature and Fisheries is responsible for coordinating cantonal tasks.
How can local communities help manage the impact of invasive species like the Asian hornet?
Interview: Understanding the Asian Hornet’s Impact on Local Ecosystems with Dr. Emma Fischer, Entomologist
Editor: Welcome, Dr. Fischer. Thank you for joining us today to discuss the recent discovery of an Asian hornet nest in the canton of St.Gallen. Can you tell us a bit about the significance of this finding?
Dr. Fischer: Thank you for having me. The discovery of the Asian hornet nest at a height of 25 meters in an oak tree is indeed significant. These hornets, which were introduced into Europe through the south of France, can influence local ecosystems, particularly by preying on honey bees. This, in turn, raises concerns for beekeepers and the overall health of pollinator populations.
Editor: It’s interesting to hear the connection with honey bees. How exactly do Asian hornets impact beekeeping and honey production?
Dr. Fischer: Asian hornets are skilled hunters of insects, and unfortunately, honey bees are among their primary targets. They can disrupt bee colonies, leading to decreased populations and, subsequently, lower honey production. Beekeepers need to be vigilant during this time, as the hornets can significantly impact the viability of their hives.
Editor: The Office for Hunting, Nature and Fisheries has advised local beekeepers to increase monitoring of their hives. What practical steps should they take?
Dr. Fischer: Beekeepers should regularly inspect their colonies for signs of Asian hornet activity, particularly visible nests or suspiciously large hornets. They should also implement protective measures, such as setting up traps or using screens around their hives to keep the hornets at bay. Reporting any sightings of nests or unusual hornet behavior to local authorities is crucial for effective management.
Editor: Beyond the Asian hornet, other invasive species like the quagga mussel and tiger mosquito are also reported in St.Gallen. How does this broader issue of neobiota affect biodiversity?
Dr. Fischer: The spread of invasive species can lead to decreased biodiversity and altered habitats. Invasive species often outcompete native species for resources, disrupt food webs, and can even introduce diseases to local fauna. Managing these invasions is necessary to protect native wildlife and maintain ecological balance.
Editor: What is the role of the Neobiota department in addressing these concerns?
Dr. Fischer: The Neobiota department at the Office for Hunting, Nature and Fisheries plays a pivotal role in coordinating responses to invasive species. They are responsible for monitoring, research, and implementing management strategies to control populations of invasive species like the Asian hornet, ensuring that local ecosystems remain resilient.
Editor: As a takeaway for our readers, what actions can individuals take to contribute to local efforts against invasive species?
Dr. Fischer: Individuals can help by staying informed, reporting sightings of invasive species, and participating in local conservation efforts. If you’re a beekeeper, monitoring your hives closely and implementing protective measures is essential. Additionally, raising awareness in your community about the impact of invasive species can inspire collective action.
Editor: Thank you, Dr. Fischer, for sharing your insights on this pressing issue. It’s essential for our readers to understand the implications of the Asian hornet and other invasive species on the environment and beekeeping.
Dr. Fischer: Thank you for having me. I hope our discussion helps foster understanding and encourages proactive measures within the community.
