Patterns of mosquito and arbovirus community composition and ecological indexes of arboviral risk in the northeast United States

Background: In the northeast United States (U.S.), mosquitoes transmit a number of arboviruses, including eastern equine encephalitis, Jamestown Canyon, and West Nile that pose an annual threat to human and animal health. Local transmission of each virus may be driven by the involvement of multiple mosquito species; however, the specificity of these vector-virus associations has not been fully quantified. Methodology: We used long-term surveillance data consistently collected over 18 years to evaluate mosquito and arbovirus community composition in the State of Connecticut (CT) based on land cover classifications and mosquito species-specific natural histories using community ecology approaches available in the R package vegan. We then used binomial-error generalized linear mixed effects models (GLMMs) to quantify species-specific trends in arbovirus detections. Primary Results: The composition of mosquito communities throughout CT varied more among sites than among years, with variatio...
