Mosquito surveillance in Europe is essential for early detection of invasive species with public health importance and for the prevention and control of pathogens like West Nile virus (WNV). Information on distribution, abundance and population dynamic of the mosquito fauna in the Emilia-Romagna region plain area (around 12,000 km2) have been collected in the frame of the Regional Vector-borne diseases surveillance program, from 2010 to 2016. The data presented document the collections of adult mosquitoes by the standardized use of CO2 traps and gravid traps in the plain area of the 9 provinces of the region. During the period 2010-2016, more than 2,400,000 adult mosquitoes belonging to 22 species were identified in a range between 88 to 110 mosquito traps, sampled every 2 weeks from the end of May to the beginning of October. The commonest and most abundant species were as follows, in decreasing order: Culex pipiens, Aedes caspius, Aedes vexans and Aedes albopictus. The most widespread species was Cx. pipiens, with highest densities in agricoltural and peri-urban habitats, followed by Ae. albopictus, most abundant in urban and peri-urban habitat. The quali-quantitative analysis of data shows that composition of the mosquito populations varied between geographical locations, seasonal period and surveillance years.
