Abstract EN
Insecticide resistance in malaria vectors threatens malaria prevention and control efforts.
In Colombia the three primary vectors, Anopheles darlingi, An.
nuneztovari s.l., and An.
albimanus, have reported insecticide resistance to pyrethroids, organophosphates, carbamates, and DDT; however, the insecticide resistance monitoring is not continuous, and the data on the prevalence of resistance is scarce and geographically limited.
We describe the resistance levels and intensity of previously detected resistant populations among primary malaria vectors from the most endemic malaria areas in Colombia.
The study was carried out in 10 localities of five states in Colombia.
Bioassays were carried out following the methodology of CDC Bottle Bioassay using the discriminating concentration and in order to quantify the intensity the specimens were exposed to 2, 5, and 10X discriminating concentrations.
Five insecticides were tested: deltamethrin, lambda-cyhalothrin, alpha-cypermethrin, permethrin, and DDT.
The results provide evidence of low resistance intensity and resistance highly localized to pyrethroids and DDT in key malaria vectors in Colombia.
This may not pose a threat to malaria control yet but frequent monitoring is needed to follow the evolution of insecticide resistance.
