PARIS (AFP) - Gene detectives on Tuesday said they had discovered how the parasite that causes malaria becomes resistant to DDT and to insecticides used in anti-malaria bednets.

A singe mutation changes a normal gene for metabolism, known as GsTe2, into one that helps the mosquito break down the insecticide molecule so that it is no longer toxic.

Insecticide resistance is a major worry in the fight against malaria.
