Susceptibility of An. gambiae s.s. Kisumu, An. gambiae s.l. Covè and An. coluzzii Akron exposed to discriminating concentrations of insecticides in WHO cylinder bioassays.
Data was pooled from routine testing on insectary-maintained mosquito strains performed between February 2020 and December 2021. Error bars represent 95% confidence intervals.

Lethal concentrations (LC50 and LC99) and discriminating concentrations of broflanilide against insecticide susceptible An. gambiae s.s. Kisumu in bottle bioassays with and without Mero® adjuvant.
Probit analysis was performed using SPSS software.
