It also underscores the potential of this strategy to modify wild mosquito populations and thereby reduce malaria transmission to humans.

Once genetically modified mosquitoes resistant to dengue are developed, scientists would test them in large field cages to see how they compete with wild mosquitoes in very controlled experiments.

Two scientists explore the controversies over releasing genetically modified mosquitoes into the wild

Before such anti-malaria mosquitoes could be effective in the wild, though, they would probably need an additional genetic tweak, says Riehle, to give them a competitive advantage over wild mosquitoes.

Fortunately, an underdominance - based system should make it fairly easy to return future generations to their original, unmodified state by releasing enough wild mosquitoes back into the population.

The study by researchers from the Wellcome Trust Sanger Institute and their collaborators also discovered that wild mosquitoes collected in Africa were genetically far more diverse than had been thought.

Even when combining 10 percent GM with 90 percent wild mosquitoes, the Plasmodium - resistance trait dominated after a few generations.

We have identified an Enterobacter bacterium isolated from wild mosquito populations in Zambia that renders the mosquito resistant to infection with the human malaria parasite Plasmodium falciparum by interfering with parasite development before invasion of the midgut epithelium.

Both approaches require careful monitoring of the spread of Wolbachia in the wild mosquito population.

Any wild mosquitoes entering a zone made disease - free with a gene drive would quickly be assimilated.

Eventually the wild mosquitoes die out, leaving the modified ones in their place.

The group also showed that the change in the microbiota resulted in a mating preference among the GM and wild mosquitoes.

These GM mosquitos preferred to mate with wild mosquitoes and passed along the desired protection to many generations of offspring.

«Disease resistance successfully spread from modified to wild mosquitoes: Mating of genetically modified species.»

The researchers found that the dengue - resistant mosquitoes live as long as the wild mosquitoes, though they do produce fewer eggs, most likely because the same mechanism involved in dialing up the immune system to fight dengue also plays a role in egg production.

«This particular Wolbachia strain is not spreading into the wild mosquito population as we had hoped,» says lead researcher Scott O'Neill of Monash University in Clayton, Australia.

Also, if any other insect bird or fish were to eat a GM mosquito this would be no different to ingesting a wild mosquito.
