[LISTEN] Naked Scientist: Malaria carrying mosquitoes killed in lab experiment
Researchers from Imperial College in London have found a less environmentally harmful way of wiping out malaria carrying mosquitoes.
Naked Scientist, Chris Smith, explains how the experiment dubbed a "gene drive" genetically modifies the population of insects in such a way that they become infertile.
What they have targeted is a gene called DBX or double sex and the interesting thing about this gene is that one form of it is switched on in female mosquitoes and makes them develop as females, a different form is switched on in males and makes them develop as males.Chris Smith, Naked Scientist
The group in Imperial have targeted just the female form so what this means is that when this gene goes into the population the males can pass it on and they are healthy and capable of mating with females and passing on the trait that the females then don't develop properly.Chris Smith, Naked Scientist
Over a number of generations this causes the population to crash.Chris Smith, Naked Scientist
