*Based on p≤0.05 in a generalized linear mixed model. Each model was denoted as a specific scenario, from the same week to 8 weeks after entomologic surveys, and index. House and Breteau indices are based on larval surveys of Aedes aegypti mosquitoes; mosquito per inhabitant, trap positivity, and adult density indices are based on adult trapping. ΔAICc, difference in corrected Akaiks information criteria; wAICc, weights of corrected Akaike information criteria.
