A number of labs have been working on making mosquitoes immune to malaria. The idea is to engineer these mosquitoes and release them into the wild, where they will compete with wild malaria-carrying mosquitoes. This in itself is a rather controversial strategy.
But it seems that after many generations with a cushy lab job, the experimental mosquitoes simply cannot compete with their wild cousins who have had to face continual 'survival of the fittest'.
