Malaria-transmitting mosquitoes in South America are evolving to evade insecticides

Study reveals genetic evolution of major malaria vector species in South America

Anopheles darlingi mosquitoes-a major vector of malaria in South America-are evolving in response to insecticides, which may make them harder to kill and malaria more difficult to control, according to a new study led by Harvard T.H. Chan School of Public Health.

Mosquitoes with deadly disease are evolving faster than insecticides can kill them

This puts millions of people at greater risk of infection

Mosquitoes carrying malaria are evolving more quickly than insecticides can kill them – researchers pinpoint how

_Anopheles darlingi_, a key carrier of malaria, is rapidly evolving resistance to insecticides. Romuald Carinci and Pascal Gaborit/Duchemin lab/Institut Pasteur de la Guyane, CC BY-SAThe fight against infectious disease is a race against evolution. Bacteria become resistant to antibiotics. Viruses adapt to spread more quickly. Diseases transmitted by insects present another evolutionary front: Insects themselves can evolve resistance to the pois…

Malaria-transmitting mosquitoes in South America are evolving to evade insecticides

Anopheles darlingi mosquitoes—a major vector of malaria in South America—are evolving in response to insecticides, which may make them harder to kill and malaria more difficult to control, according to a new study led by Harvard T.H. Chan School of Public Health. The study appears in Science. It is the first study to sequence a large number (>1000) of complete genomes of Anopheles mosquitoes in the Americas, where there are more than 600,000 cas…

Complete Genome Sequencing Reveals Malaria Mosquito Adapting to Insecticides

A sweeping population‑genomics effort has generated the first large collection of complete genomes for Anopheles darlingi, the dominant malaria vector across South America. The dataset—more than 1,000 high‑coverage genomes from six countries—offers the clearest picture to date of how this mosquito species is structured, how it adapts, and which genetic pathways may be shifting under insecticide pressure. Malaria transmission in South America rem…
