Abstract: The principal La Crosse virus (LACV) vector, Aedes triseriatus, is associated with forested habitats and may be outcompeted by accessory vectors in urban areas. We used standardized oviposition cups to sample LACV vectors along an urbanization gradient in 2021 and 2022 and found that the relative abundance of Ae. triseriatus increased with site-level canopy cover. Spatial heterogeneity in LACV transmission risk may be related to land cover and associated vector community compositions.
