The Fight Against the Asian Hornet Continues on Groix

Thanks to the efforts of the people of Groix, in 2024, more than 4,000 Asian hornet queens were neutralized: Asian hornets were less numerous than in 2023. However, black bees and Groix’s biodiversity remain fragile, and the Asian hornet continues to be a threat to pollinators in general.

BreizhGo Océane actively supports organizations that work to protect biodiversity on the islands it serves. The fight for biodiversity and the protection of the black bee, an endangered endemic bee in France and Europe, led by AsanGx and many volunteers on the Island of Groix, is a prime example.

Asian hornets, a threat to the Island of Groix

From summer onwards, the Asian hornet kills insects, especially pollinators, to feed its larvae. In just a few years, it has become one of the main threats to the black bees of the island. Indeed, lacking natural predators, the population of Asian hornets grows rapidly at the expense of other insects.

Pollinators are essential for the survival and reproduction of most plant species. Nearly 80% of crops that feed the world’s population are pollinated, among other things, by bees.

AsanGx Protects Biodiversity on Groix

We need your help to detect Asian hornet nests on Groix.
Once you’ve arrived on the Island of Groix, all you need to do is observe! Primary nests are built between mid-March and May by the queen hornet. They are usually sheltered from the rain in garden sheds, roof eaves, or shutters. Once you locate a primary nest, AsanGx invites you to contact them by phone at 06 19 71 45 85.

As for secondary nests, which are larger and appear later, they should not be approached but should be reported immediately to the hornet contact person in the municipality at 02 97 86 80 95.
