This week I read an article about the branching off of a species of mosquito in Africa into two different species. When they studied the two strains, dubbed M and S they found 400,000 points in the genome where there was a difference. This is a problem because Malaria is prevalent in Africa and one way to control the disease is to control the Mosquito population. Having a new strain means that insecticides that work on one strain might not work on the other strain, meaning that insecticides used in the wrong area on the wrong strain will be ineffective. They believe that the emergence of seperate strains is from different environmental conditions such as predators, larval conditions, weather changes and insecticides used in particular areas. The M and S strains originated from the Gambiae strain which was previously the main strain of malaria carrying mosquito.
Malarial Mosquitos speciation???
