The study reveals insecticide resistance impacts vector control strategies against malaria in Anopheles gambiae populations.

This research investigates the status of insecticide resistance and malaria transmission indicators in Anopheles gambiae in Burkina Faso.
Conducted World Health Organization-standard susceptibility bioassays on Anopheles populations
Tested multiple insecticides including pyrethroids and organophosphates
Performed synergist bioassays using piperonyl butoxide to assess metabolic resistance
Determined Plasmodium infection rates using Polymerase Chain Reaction
High resistance levels to dichlorodiphenyltrichloroethane and pyrethroids were found
Susceptibility to bendiocarb and pirimiphos-methyl was observed in most locales
Restoration of pyrethroid susceptibility via piperonyl butoxide indicates metabolic resistance mechanisms
An. arabiensis predominated with a sporozoite infection rate of 27.4% and significant contribution to malaria transmission.

Amara et al. (2025) studied this question.
