Map of the MRR set-ups in Coldrerio and Lugano. The traps were deployed in all directions from the self-marking units (green star in the centre) across a circular area with a radius of 1.0 km. Red dots represent positive traps while the size of the dots corresponds to the number of marked mosquitoes caught at each site. Grey dots represent negative traps. Circular black lines represent the four annuli at 250, 500, 750 and 1000 m from the marking units. Basemap source: OpenStreetMap and contibutors CC-BY-SA
