Nearly 300,000 altered mosquitoes were released in two northern Australia towns to see if they would pass on the bacteria when they mated with their wild counterparts.

Among the challenges researchers face is ensuring that GM mosquitoes can compete and mate with their wild counterparts so the desired modification is preserved and spread in the wild population.

Replacing ordinary mosquitoes in the wild with genetically modified mosquitoes hasn't yet been attempted, though scientists have been working on «gene drive» techniques that cause DNA modifications to spread quickly into a wild population via ordinary breeding.

To understand how mosquitoes are evolving, researchers working with the Anopheles gambiae 1000 genomes project sequenced the DNA of 765 wild Anopheles mosquitoes.

Nevertheless, the study suggests that mosquitoes can be genetically modified to compete in nature with wild populations and spread resistance to the malaria - causing parasite.

One of the few examples that were deemed as not cost - effective under certain circumstances was the use of genetically modified male mosquitoes that mate with wild female mosquitoes and do not produce offspring.

The hope is that the method could be used to engineer populations of insects in the wild, with the goal of reducing mosquito - borne diseases such as malaria or dengue fever, or controlling agricultural pests, such as those that transmit citrus greening disease.

The company says they can be effective at controlling pest populations: Altered male mosquitoes are released into the wild to mate with females.

Called RIDL (for «Release of Insects with Dominant Lethality»), it involves releasing large numbers of male mosquitoes with their genes adjusted so that when they mate with wild females, the offspring don't survive.

In the paper, the researchers discuss how recent breakthroughs in CRISPR - Cas9 gene editing technology coupled with their discovery last year of a male sex determining gene Nix could be a winning combination for tipping the male - female mosquito ratio in the wild.

They can not produce viable offspring with other insects in the wild, not even with other species of mosquito.

In 2009 - 2010, with government of the Cayman Islands, the first outdoor GM mosquito experiments were conducted, showing that RIDL male mosquitoes could indeed find, mate with and suppress a wild mosquito population.
