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...研究背景：在美国东北部地区，蚊虫可传播多种虫媒病毒（arbovirus），包括东部马脑炎病毒、詹姆斯敦峡谷病毒以及西尼罗河病毒，上述病毒每年均会对人类与动物健康构成威胁。各类病毒的本地传播或由多种蚊虫物种协同驱动，但目前尚未完全量化这些媒介-病毒关联的特异性。 研究方法：本研究依托18年间持续收集的长期监测数据，基于土地覆盖分类与蚊虫物种特异性自然史特征，借助R包vegan中的群落生态学分析方法，评估康涅狄格州（Connecticut, CT）内蚊虫与虫媒病毒的群落组成；随后采用二项分布误差广义线性混合模型（generalized linear mixed effects models, GLMM），量化蚊虫物种在虫媒病毒检测中的特异性趋势。 主要结果：康涅狄格州全境的蚊虫群落组成在不同采样点间的差异大于年度间差异，且其变异……
