Fig 1. Ae. aegypti mosquitoes caught per week by study arm.

Panel A is the mean number of Ae. aegypti mosquitoes caught per BG trap per week and panel B is the ratio of female to male Ae. aegypti caught. 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. The warm, wet season in Yogyakarta is from November to April.
