“…Therefore, the true national prevalence depends on the frequency of such hot spots in Denmark. Species ratios may also be strongly influenced by sampling design with C. pipiens being more prevalent than C. torrentium in CO 2 -baited traps compared to larval sampling and gravid traps (Weitzel et al 2011, Hesson et al 2015b. The reason for this remains unknown, but it has been speculated that C. torrentium, being strictly ornithophilic, spends its time around bird nests in high trees and only visits the ground to oviposit (Petriae et al 1999).…”

European Culex pipiens and Culex torrentium are morphological fairly similar mosquito species with potentially different vector competences for pathogenic viruses. The relative abundance of the two species is therefore important for quantifying the potential for disease transmission in Denmark. Mosquitoes were sampled from 74 different sites in Denmark with CO2 and octenol-baited suction traps. A total of 285 Culex specimens were identified to species using a restriction enzyme assay. Culex pipiens was the dominating species with 220 (77%) specimens caught at 22 different sites, while 65 (23%) specimens were identified as C. torrentium and only caught at 4 sites. The ratio of the two species differed significantly between sites with C. torrentium dominating in just a single location. Both mosquito species were predominantly caught late in the Danish mosquito season, from mid-August and onwards.

“…• gravid traps baited with hay infusion added with yeast (almost 2.5 l): these traps attract Culex females that have blood fed and are ready to lay their eggs [43] in sites containing water high in organic matter, increasing together the likelihood of collecting infected mosquitoes. Each trap worked for a 24-h period.…”

In Italy, the surveillance of Mosquito-Borne Diseases (MBDs) is regulated by two national preparedness plans: (1) for West Nile and Usutu viruses, integrating human and veterinary surveillance in order to early detect viruses circulation and to quickly apply control measures aimed at reducing the risk of transmission through blood and blood components and (2) for Arbovirosis transmitted by Aedes mosquitoes, mainly Chikungunya, Dengue and Zika viruses, based on surveillance of both imported and autochthonous human cases. This chapter reports the results of the application of these National Plans in Northwestern Italy and their impact for human health. In detail, we present the coordinated activities enforced in Piemonte and Liguria Regions, as a good example of the 'One Health approach' to control MBDs and prevent human transmission.

“…SINV exemplifies the opposite situation; it is endemic in Finland and central and northern Sweden. In these regions, SINV is often detected in mosquitoes and reports of the disease occur regularly [8][9][10][11][12]. SINV has also been detected in mosquitoes in central and southern Europe, but with a significantly lower infection rate and with no reports of human cases [2,13,14].…”

There are three human pathogenic bird-viruses transmitted by Culex mosquitoes in Europe: the alphavirus Sindbis and the flaviviruses West Nile virus and Usutu virus. Cases of Sindbis fever occur in the north while the flaviviruses are reported from southern Europe. In this study, 7933 Culex pipiens/torrentium mosquitoes from southern Sweden were screened by RTqPCR for these viruses. None of the mosquitoes were positive for viral RNA. The importance of mosquito species composition is discussed as a potential explanation to the lack of detection of mosquito-borne viruses in southern Sweden. However, continued surveillance of mosquitoes for Flaviviruses would be valuable as an early warning for public health awareness.
