DESCRIPTION (provided by applicant): This is a pilot study to investigate the potential impacts of green stormwater infrastructure on the ecology and management of mosquito vectors of West Nile Virus (WNV) in urban ecosystems. WNV has caused the largest arboviral encephalitis epidemic in U.S. history, and the propensity of urban stormwater structures to support large populations of the vectors Culex pipiens and Cx. restuans has contributed to these epidemics. At present, suppression of vector populations via the delivery of larva-specific insecticides (i.e. larvicides) to urban stormwater structures is one of the primary strategies for prevention and management of WNV epidemics. However, despite this widespread strategy, mosquito and WNV outbreaks continue to be a pressing public health challenge in urban ecosystems. While the field of stormwater management is rapidly evolving to include Green Infrastructure (GI) tools that reduce the volume of runoff and contaminants entering municipal storm and septic sewer systems, scant attention has been paid to how these changes will influence vector production, vector control and ultimately human risk of exposure to mosquito-borne pathogens. This project will take advantage of two "natural" experiments to quantify how replacement of traditional storm water catch basins with infiltration catch basins (I-CBs) and rain gardens associated with catch basins (RG-CBs) will affect the ecology and management of mosquito vectors in the City of Aurora, IL. Our overall aims are to a) determine if GI infrastructure tools (I-CBs and RG-CBs) accumulate or retain an insufficient volume of water to allow juvenile mosquitoes to complete development; b) determine if GI infrastructure tools increase the efficacy and duration of a sustained-release larvicide formulation; and c) determine if the neighborhood-scale implementation of a GI tool reduces the abundance of adult vector mosquitoes. The findings from this study may provide new insights for understanding the potential of GI practices to complement Integrated Vector Management practices in urban ecosystems by: a) reducing the quantity or quality of habitats suitable for mosquito development (i.e. source reduction), b) extending the efficacy of sustained-release larvicides used to control mosquito development in catch basins, and c) diminishing public health risks from exposure to insecticides and to vector- borne pathogens.

描述（由申请人提供）：这是一项试点研究，旨在调查绿色雨水基础设施对城市生态系统中西尼罗河病毒（WNV）的生态学和管理的潜在影响。 WNV在美国历史上引起了最大的弧菌病毒脑炎的流行，以及城市雨水结构的倾向，支持大量载体人群Culex Pipiens和Cx。餐馆为这些流行病做出了贡献。目前，通过将幼虫特异性杀虫剂（即幼虫）传递到城市雨水结构是预防和管理WNV流行病的主要策略之一。然而，尽管采取了广泛的战略，但蚊子和WNV爆发仍然是城市生态系统中的公共健康挑战。虽然雨水管理领域正在迅速发展，以包括绿色基础设施（GI）工具，这些工具减少了进入市政风暴和化粪池下水道系统的径流量和污染物的数量，但对这些变化的关注很少，这些变化如何影响媒介的生产，媒介控制，最终对摩squito-barorne-barorne-Barorne病原体暴露于人类风险。该项目将利用两个“自然”实验，以量化如何用渗透池（I-CB）和雨水替换传统的雨水捕捞盆地 与捕获盆地（RG-CB）相关的花园将影响伊利诺伊州奥罗拉市的蚊子媒介的生态和管理。我们的总体目的是a）确定胃肠道基础设施工具（I-CB和RG-CB）是否积累或保留了不足的水以使少年蚊子完全开发； b）确定胃肠道基础设施工具是否会增加持续释放幼虫的疗效和持续时间； c）确定GI工具的邻级实施是否减少了成人媒介的丰度。 The findings from this study may provide new insights for understanding the potential of GI practices to complement Integrated Vector Management practices in urban ecosystems by: a) reducing the quantity or quality of habitats suitable for mosquito development (i.e. source reduction), b) extending the efficacy of sustained-release larvicides used to control mosquito development in catch basins, and c) diminishing public health risks from exposure to insecticides并致病原体。
