Effect of Trapping Methods, Weather, and Landscape on Estimates of the Culex Vector Mosquito Abundance

摘要: The local abundance of Culex mosquitoes is a central factor adding to the risk West Nile virus transmission, and vector data influence public health decisions. This study evaluated differences in estimates from trapped using two common methods: CO₂-baited CDC light traps infusion-baited gravid suburban, Chicago, Illinois. On weekly basis, methods were modestly correlated (r = 0.219) across 71 weeks over 4 years. Lagged weather conditions up four associated with number collected traps. Collections higher temperature same week, precipitation one, two, before week trapping, lower maximum average wind speed. one earlier, earlier. significantly semi-natural areas compared residential areas, but did not vary by landscape type. These results highlight importance surveillance used assessment estimates. Measures exposure should assess carefully how mosquito has been estimated integrated into assessments transmission risk.
