Figure 5. Patterns of insecticide resistance in Anopheles
gambiae following exposure to permethrin and deltamethrin treated
nets. Female Anopheles gambiae s.s. from the Democratic Republic
of Congo (DRC) and Uganda exhibited very high resistance (low %
mortality) in WHO cone assays to permethrin (Olyset) and deltamethrin
(PermaNet 2.0) LLINs. There was an increase in mortality following
exposure to an increased concentration of deltamethrin (PermaNet 3.0
Side) and very high mortality following exposure to pyrethroid plus the
P450 inhibitor piperonyl butoxide (PBO) Olyset+ and PermaNet 3.0 Top.
95% confidence intervals are shown.
