British scientists found ancient insecticide resistance in African malaria mosquitoes, aiding new control efforts.
British scientists have uncovered genetic clues about how Anopheles funestus, a major malaria-transmitting mosquito in Africa, is evolving to resist control efforts.
By analyzing genomes from 656 modern and 45 historic mosquito specimens, researchers found high genetic variation across Africa, with some populations mixing widely while others remain isolated.
The study revealed that insecticide resistance mutations existed as early as the 1960s, indicating the species' fast evolution.
Findings will help improve targeted control strategies, including adapting gene drive technology to reduce female mosquito populations and curb malaria transmission.
