GENETICALLY MODIFIED MOSQUITOES
US conducted an open-air study of genetically engineered mosquitoes which shows promising results
- Mosquitoes produced in a laboratory
- A self-limiting gene that prevents female mosquito offspring from surviving to adulthood.
- A fluorescent marker gene that glows under a special red light. This allows researchers to identify GM mosquitoes in the wild.
- GM mosquito eggs that carry the self-limiting gene are released into an area. Once they have hatched and develop through to the adult stage, they are available to mate with wild females. The genes are passed on to offspring.
- The male mosquitoes have a protein (the tTAV-OX5034 protein) that prevents female offspring from surviving when male OX5034 mosquitoes mate with wild female mosquitoes.
- The female offspring die before they become adults. The expected result is that the number of Aedes aegypti mosquitoes in the area decreases.
