“…Many studies have highlighted the importance of weather and climate as determinants of the spatio-temporal distribution and abundance of mosquitoes [25][26][27][28]. Climate change [29], may be driving current expansions in the geographical range of mosquitoes, particularly northern expansion of ranges [30][31][32].…”

Weather and land use can significantly impact mosquito abundance and presence, and by consequence, mosquito-borne disease (MBD) dynamics. Knowledge of vector ecology and mosquito species response to these drivers will help us better predict risk from MBD. In this study, we evaluated and compared the independent and combined effects of weather and land use on mosquito species occurrence and abundance in Eastern Ontario, Canada. Data on occurrence and abundance (245,591 individuals) of 30 mosquito species were obtained from mosquito capture at 85 field sites in 2017 and 2018. Environmental variables were extracted from weather and land use datasets in a 1-km buffer around trapping sites. The relative importance of weather and land use on mosquito abundance (for common species) or occurrence (for all species) was evaluated using multivariate hierarchical statistical models. Models incorporating both weather and land use performed better than models that include weather only for approximately half of species (59% for occurrence model and 50% for abundance model). Mosquito occurrence was mainly associated with temperature whereas abundance was associated with precipitation and temperature combined. Land use was more often associated with abundance than occurrence. For most species, occurrence and abundance were positively associated with forest cover but for some there was a negative association. Occurrence and abundance of some species (47% for occurrence model and 88% for abundance model) were positively associated with wetlands, but negatively associated with urban ( Culiseta melanura and Anopheles walkeri ) and agriculture ( An. quadrimaculatus, Cs. minnesotae and An. walkeri ) environments. This study provides predictive relationships between weather, land use and mosquito occurrence and abundance for a wide range of species including those that are currently uncommon, yet known as arboviruses vectors. Elucidation of these relationships has the potential to contribute to better prediction of MBD risk, and thus more efficiently targeted prevention and control measures.

“…Il existe également un risque accru que d'autres maladies exotiques transmises par les moustiques, comme la dengue et la fièvre Chikungunya -et les moustiques qui les transmettent -s'établissent au Canada. En raison des changements climatiques, ces moustiques exotiques, qui ont été introduits suite à l'intensification des transports, des échanges de denrées et de matériel à l'échelle internationale, trouvent maintenant au Canada les conditions environnementales dont ils ont besoin pour survivre (9).…”
