Number of Wolbachia (wAlbB) female mosquitoes in the population with FRER: 0 with (A) Reduced intensity of 40,000 releases per week (S3A [I]), (B) Baseline intensity of 60,000 releases per week (S3A [II]) and (C) Increased intensity of 80,000 releases per week (S3A [II]) of male releases under the first strain female irradiation (S3A). Number of Wolbachia (wAlbB) female mosquitoes in the population with FRER: 0 with (D) Reduced intensity of 40,000 releases per week (S3B [I]), (E) Baseline intensity of 60,000 releases per week (S3B [II]) and (F) Increased intensity of 80,000 releases per week (S3B [II]) of male releases under the first strain male and female irradiation (S3B). Number of Wolbachia (wAlbB) female mosquitoes in the population with FRER: 0 with (G) Reduced intensity of 40,000 releases per week (S3B [I]), (H) Baseline intensity of 60,000 releases per week (S3B [II]) and (I) Increased intensity of 80,000 releases per week (S3B [II]) of male releases under the second strain introduction (S4). The lighter shade solid lines represent the 1000 simulations, and the dark solid lines represent the median of the 1000 simulations. The blue and brown dotted vertical line represents the start and end of the intervention (S3A, S3B and S4) respectively. The red solid line represents the baseline scenario (S1).
