The most dangerous type of malaria-carrying mosquito, which kills up to a million people each year, is evolving into two different species, posing grave problems for controlling the transmission of the blood parasite.
Scientists have found that Anopheles gambiae, which is widespread across Africa and is responsible for about half of the 500 million new cases of malaria each year, has split into two genetically different strains that are well on their way to becoming distinct species.
The revelation could present real difficulties in controlling malaria because eradication strategies directed against one mosquito species may not be effective against another, according to the scientists who discovered the genetic differences between the two strains.
"From our new studies, we can see that mosquitoes are evolving more quickly than we thought and that unfortunately strategies that might work against one strain of mosquito might not be effective against another," said Mara Lawniczak of Imperial College London.
