On the 22nd and 23rd of March, we co-hosted the workshop ‘Strengthening the role of citizen science and digital entomology in mosquito-borne disease surveillance in Europe’. It was co-organized by Wageningen University and Research (WUR) and the Centre for Advanced Studies of Blanes (CEAB) and supported by Aedes invasive mosquito (AIM) COST and InfraVec2.
