Effect of different doses of NeemAzal ® on An. coluzzii and G. p. gambiensis host-seeking behaviour. a An. coluzzii activation rate, expressed as the proportion of mosquitoes caught in both collecting boxes out of the total number released in the downwind cage (n = 503 mosquitoes). b An. coluzzii anthropophilic rate, expressed as the proportion of mosquitoes caught in the collecting box emitting human odour out of the total number retrieved from both collecting boxes (n = 146). Mosquito behaviour was gauged three days after receiving blood supplemented with NeemAzal ® doses of 0 μg/ml (control group consisting of blood supplemented with solvent solution only), 500 μg/ml (NA500), 1000 μg/ml (NA1000) and 2000 μg/ml (NA2000). Dar grey bars: human side, white bars: calf side (c) G. p. gambiensis activation rate, expressed as the proportion of flies caught in both host chambers out of the total number released in the central chamber (n = 1178 flies), d G. p. gambiensis anthropophilic rate, expressed as the proportion of fly caught in the human chamber out of the total number retrieved from both host chambers (n = 363). Fly behaviour was gauged two days after receiving NeemAzal ® doses of 0 μg/ml (control), 12.5 μg/ml (NA12.5), 25 μg/ml (NA25) and 50 μg/ml (NA50). Light grey bars: human side, white bars: calf side
