Temporal Variation in Mosquito Vector Population Dynamics in Urban Areas

Shengyang Wang, S Garrison Carruth, Chalmers Vasquez, John Townsend, Vivek Raman, John-Paul Mutebi, Marco Ajelli, André Barretto Bruno Wilke

This study examines seasonal variations in mosquito population dynamics of Ae. aegypti and Cx. quinquefasciatus in three U.S. counties, finding species- and location-specific patterns that inform local mosquito control strategies.

Short-term forecasts of Aedes aegypti relative abundance to enhance mosquito control situational awareness

Utkarsh Bhosekar, Paulo Cesar Ventura, Megan D. Hill, Allisandra G. Kummer, Shreeya Mhade, Jagadeesh Chitturi, Chalmers Vasquez, John-Paul Mutebi, John Townsend, Maria Litvinova, André Barretto Bruno Wilke, Marco Ajelli

This paper develops a multi-model forecasting framework to predict Aedes aegypti abundance up to 4 weeks ahead, showing improved performance with longer horizons and highlighting challenges in low activity or atypical peak periods.
