The mosquito, Anopheles gambiae, which was thought to be splitting into two completely new species, may actually have a more complex range of forms due to frequent inter-mating, scientists have found. The resulting hybrids may have implications for insecticide resistance and malaria parasite infectivity.
"Our research shows that Anopheles gambiae mosquitoes, which are responsible for most cases of malaria in Africa, are more genetically complex than we thought due to interbreeding," said David J. Conway
The sustainability of the gains achieved in malaria control in Zanzibar is seriously threatened by the resistance of malaria vectors to pyrethroids and the short-lived efficacy of LLINs. This study has revealed that even in relatively well-resourced and logistically manageable places like Zanzibar, malaria elimination is going to be difficult to achieve with the current control measures.
