Fig 5. Ratio of Ae. aegypti to Ae. albopictus mosquitoes caught per week by study arm.
Weekly counts of Ae. aegypti and Ae. albopictus were aggregated across 12 wMel-treated clusters and 12 untreated clusters. Releases of wMel-infected Ae. aegypti mosquitoes occurred from March 2017 –December 2017 (yellow shading). The first nine weeks of releases are excluded from analyses due to unequal trapping density in the treated and untreated clusters. There was an average of 4 BG traps/km2 in wMel-treated clusters and 5 BG traps/km2 in untreated clusters in the pre-release period, and 16 BG traps/km2 and 15 BG traps/km2 during and post-release.
