Australian researchers have developed an innovative technique with genetically modified mosquitoes that could be key in the fight against tropical diseases such as malaria and dengue.
This breakthrough, recently published in the journal Nature Communications, promises to reduce the spread of these diseases through the so-called “sterile insect technique”.
The technique involves breeding mosquitoes whose sperm contain toxic proteins lethal to females after mating. This method, targeted specifically at females, is crucial since they are the ones that bite and suck blood, thus spreading diseases.
Sam Beach, a scientist at Macquarie University in Australia, stated: “This method could be as effective as pesticides without affecting beneficial species.” Initial tests with fruit flies have shown promising results, with a noticeable reduction in the lifespan of females crossed with “toxic” males.
Safety and efficiency of the “sterile insect technique”
Researcher Maciej Maselko pointed out that the team will carry out rigorous tests to ensure the safety of the method in humans. Genetic engineering has been used for years to control mosquito populations, and this new approach could be an additional tool in the fight against tropical diseases.
Initial tests have used fruit flies, a common species in laboratory research due to their short two-week lifespan. Results showed a significant reduction in the longevity of females crossed with “toxic” males.
As research progresses, it is expected that this technique can be successfully applied to disease-transmitting mosquitoes.
The study, published in Nature Communications, highlights the importance of continuing to explore innovative methods for vector control and tropical disease prevention. With a focus on safety and effectiveness, this breakthrough could revolutionize the control of mosquito-borne diseases.
