Fig 3. Impact of ORS on malaria vector biting rates.

Fig 3

ORS intervention was carried out on 3rd and 4th December 2016 in MK-509 and on 5th and 6th December 2016 in SP-513. Gradient-filled panels show previous estimate of the longevity of the residual insecticidal effects of lambda-cyhalothrin mist applied to outdoor vegetation (98 days) [32]. Error bars indicate the negative binomial regression 95% confidence intervals. Abbreviations: b/h/n: bites /host /night; CI, confidence interval; HBR, human-biting rate; ORS, outdoor residual spraying.
