Caractérisation écologique des milieux humides à larves de moustiques (Culicides) de la région subarctique continentale d'Opinaca (territoire de la Baie de James, Québec)

Abstract

Twenty mosquito species were collected in a low-subarctic area located between Eastmain River and Petit-Opinaca Lake, Quebec (52°15′ N, 76°38′ W). Qualitative and quantitative analyses of larval mosquito populations identified 20 ecological units that served as larval breeding sites. The data revealed typical larval associations such as Aedes canadensis – Aedes decticus, characteristic of the open bog series, Aedes communis – Aedes pionips of alder–willow groves (Salix planifolia – Alnus rugosa), Aedes intrudens and Aedes cinereus in flooded riparian areas. The ecology of species with summer larvae is also described: Culex restuans, Culex territans, Culiseta alaskaensis, and Culiseta impatiens.
