Knock-Down (KD) effect of different doses of NeemAzal ® on G. p. gambiensis. a Proportion of knocked-down flies over 7 days of observation (day 1 = day after blood meal). Flies received blood supplemented with NeemAzal ® doses of 0 μg/ml (control group consisting of blood supplemented with DMSO solvent solution only), 500 μg/ml (NA500), 1000 μg/ml (NA1000) and 2000 μg/ml (NA2000) (2 replicates, in total 1120 were flies examined). b Proportion of KD flies over time with NeemAzal ® concentrations reduced by a factor of 10 (1 replicate, totally 560 flies examined). c Proportion of KD flies over time with NeemAzal ® concentrations reduced by a factor of 40 (1 replicate, in total 560 flies were examined). Each colour line represents a LOESS curve fitted to each treatment group
