Vector Burden of Aedes aegypti and Aedes albopictus Populations in Residential Versus Non-Residential Areas of the Urban Environment in Tapachula, Chiapas, Southeastern Mexico

José Genaro Ordóñez-González, Kenia Mayela Valdez-Delgado, Farah Zamira Vera-Maloof, Luis Alberto Cisneros-Vázquez et autres

Dengue outbreaks highlight the need to quantify how environments sustain populations of the mosquito vectors Ae. aegypti and Ae. albopictus. Most control activities focus on households, while non-residential premises receive little attention. We conducted a cross-sectional ovitraps survey in August 2025 in …
