Anopheles malaria mosquitoes in Africa and Latin America are evolving in response to human activity, studies in both continents have found.
Anopheles gambiae, the most significant malaria vector in Africa, is developing increasing resistance to pyrethroid insecticides, a study published in Scientific Reports this month shows. Synthetic pyrethroids are the most commonly used insecticide for controlling malaria mosquitoes worldwide.
The team of researchers from Kenya, Ghana and the US say the indiscriminate use of pyrethroid insecticides in agriculture and public health programs could be responsible for the moderate and high-intensity resistance.
