Abstract: Cities are uniquely heterogeneous landscapes, with changes in social and environmental conditions at relatively fine spatial scales. Interactions between physical infrastructure, weather, and resident behavior can generate non-linear or emergent properties in disease vector populations and transmission processes. Despite recurrent emergence of mosquito-borne arboviruses in the western hemisphere (i.e., Zika, chikungunya) and regional expansions of a potential Aedes vector (the tiger mosquito) across temperate cities, the spatio-temporal drivers of heterogeneous mosquito infestations across urban landscapes are not well understood. We present data from neighborhoods representing a steep gradient in household income and infrastructure investment. In each year, existing juvenile habitat and adult mosquitoes were sampled regularly between May and October across ~1400 parcels to evaluate how block and neighborhood-level habitat conditions related to socio-economic status influence mosquito species composition, population abundances, and human biting risk. We explicitly examine human behavior and perceptions that facilitate mosquito production and exposure risk. Finally, our work relies on diverse engagement strategies with residents and local organizations to test theory through local interventions.
