Figure 2. Effect of window screens and eave baffles treated with 13 combinations of insecticides and binding agents on malaria vector mosquito mortality rates inside experimental huts, Tanzania. A) Anopheles funestus. B) An. arabiensis. Huts were previously sprayed with 1 of 3 alternative indoor residual spraying regimens (Technical Appendix 1) and occupied by 2 volunteers sleeping under pyrethroid-treated, long-lasting insecticidal nets. IRS, indoor residual spraying. Error bars indicate 95 CIs. Estimated mean mortality rates and 95% CIs, as well as statistical contrasts between the most relevant treatment pairs, are indicated in Technical Appendix 2).
