VUB student team develops innovative ‘Trojan horse’ in the fight against the Asian hornet
BRUSSELS 9 November 2026 – An interdisciplinary team of students from the Vrije Universiteit Brussel is taking part in iGEM, the prestigious international synthetic biology competition in Paris (13–16 November), this autumn. Using a clever combination of artificial intelligence, a mechanical trap and protein nanofibres, they are presenting a targeted method to efficiently control populations of the Asian hornet.
The Asian hornet poses an ever-increasing threat to local biodiversity and the bee population. As existing hornet traps often catch only a few individuals and the queen continues to lay eggs in the nest, the current approach offers little in the way of a satisfactory solution. Furthermore, traditional chemical pesticides cause damage to the wider ecosystem.
Driven by AI, spread by the hornet
The VUB team has developed a solution using a biological insecticide deployed according to the ‘Trojan horse’ principle. The innovation combines three elements into a targeted platform:
- Smart AI identification: As the biological pesticide is not naturally selective, an AI-driven detection system recognises, with over 99 per cent accuracy, whether an Asian hornet is trapped in the trap. This prevents beneficial insects, such as honeybees, from coming into contact with the agent.
- Specific adhesion via nanofibres: Once inside the trap, the hornet is fitted with a biological ‘sticker’ consisting of a network of protein nanofibres equipped with chitin-binding domains, ensuring they adhere optimally to the insect’s exoskeleton. The sticker contains the natural soil fungus Beauveria bassiana, a recognised natural pesticide in agriculture.
- Targeted nest control: Upon release, the hornet returns to the colony, which is then infected with the insecticidal fungus. In this way, the entire nest is tackled from within without harmful side effects for the environment.
A scalable platform for the future
The project goes beyond simply controlling the Asian hornet. Thanks to its modular design, the system offers a universal platform that can be adapted to other invasive species or pests that are becoming more prevalent due to climate change.
Alongside scientific development, the team emphasises community engagement and education. For example, the students organised workshops on AI and synthetic biology for primary and secondary schools. In synthetic biology, biological processes and materials are combined to create new technological developments with societal applications.
On 21 October, all protocols and results were made publicly available at https://2026.igem.wiki/vub-brussels/. This month, the team will present the project at the Grand Jamboree in Paris, the culmination of the renowned iGEM competition.

About iGEM and the VUB
The iGEM (International Genetically Engineered Machine) competition was founded at MIT in 2003 and brings together thousands of students worldwide every year to solve societal problems using synthetic biology. Through this participation, the VUB team aims to lay the foundations for a permanent, annual student initiative within the university.
The project was realised with the support of Prof. Dr Han Remaut’s research laboratory and the Vrije Universiteit Brussel, as well as through technological partnerships including Anthropic.
