Means of Culicinae aquatic stages according to environment factors. a Upstream (‘1’), at the city level (‘2’) and downstream (‘3’). b Distance to the river: <500 m from the river median line (‘1’), between 500 and 1500 m (‘2’) and beyond 1500 m (‘3’). c Typology of sampled breeding sites. d According to the surface of water bodies equals decimal log from 0.1 m2 (=1) to <1000 m2 (=5), >1000 m2 (=6), in contact with the river (=7). The ‘8’ (no access) or ‘0’ (dry) values have not been sampled
