Resumo: The incidence of mosquito-borne diseases is increasing in Europe, partly due to the incursion of a number of invasive species known to be vectors of dengue - chikungunya viruses, but also due to the involvement of native species in the transmission of West Nile virus - malaria. For some of these pathogens, there is a risk of the re-emergence of vector-borne diseases that were once widespread in Europe, but declined partly due to large-scale l--drainage projects. Some mosquito species exploit container habitats as breeding sites in urban areas; an adaptation to human-made micro-habitats resulting from increased urbanisation. However, many species thrive in natural wetl- ecosystems. Owing to the impacts of climate change there is an urgent need for environmental adaptation, such as the creation of new wetl-s to mitigate coastal - inl- flooding. In some cases, these initiatives can be coupled with environmental change strategies to protect a range of endangered flora - fauna species by enhancing - extending wetl- l-scapes, which may by driven by European legislation, particularly in urban areas. This paper reviews field studies conducted in Engl- to assess the impact of newly created wetl-s on mosquito colonisation in a) coastal, b) urban - c) arable reversion habitats. It also considers the impact of wetl- management on mosquito populations - explores the implications of various water - vegetation management options on the range of British mosquito species. Underst-ing the impact of wetl- creation - management strategies on mosquito prevalence - the potential risk of increasing the levels of nuisance or disease vector species will be crucial in informing health - well-being risk assessments, guiding targeted control, - anticipating the social effects of extreme weather - climate change. Although new wetl-s will certainly extend aquatic habitats for mosquitoes, not all species will become a major nuisance or a vector concern as a result. Underst-ing how the design - management of wetl-s might exacerbate mosquito densities is crucial if we are to manage nuisance mosquitoes - control vector species in the event of a disease outbreak. This entomological evidence-base will ensure that control strategies achieve optimal efficacy at minimal cost.
