Figure 3. — Effect of indoor residual spraying (IRS) campaigns on detected prevalence (A and C) and daily entomologic inoculation rate (EIR) (B and D). Simulations use Namawala, Tanzania weather and mixture of vector species, with (A and B) based on actual Namawala EIR and with the vector populations in (C and D) reduced to 0.1 of original values. Results are shown for two separate values of Anopheles arabiensis endophagy. Disease persists for all simulations in (A and B), but disease fades out in (C and D) with the exception of the 70% IRS coverage for An. arabiensis feeding indoors only 47% of the time.
