Once these are bred in large numbers they can be released and will push the normal mosquitoes out by sheer numbers. If we are really lucky and this is a dominant gene, we can release them and they will gradually spread the trait through the wild population.
The limiting characteristic is dominance of the gene, without it the malaria strain can be reduced but not eliminated in the wild. The intent to place the gene in the wild is mentioned in the Arizona Republic article, and by the BBC.
