Australian Scientists Use Genetically Engineered Mosquitoes to Combat Malaria and Dengue Fever

Jan 8, 2025, 11:10 AM

Australian scientists, including Sam Beach and Maciej Maselko from Macquarie University, have developed a novel pest control method involving genetically engineered mosquitoes with 'toxic' semen, aimed at combating the spread of tropical diseases such as malaria and dengue fever. The 'toxic male technique' involves breeding mosquitoes that express venomous proteins in their semen, which are lethal to female mosquitoes after mating. Initial trials on fruit flies demonstrated that females mating with 'toxic' males had significantly reduced lifespans. The research, published in the journal Nature Communications, suggests this method could work as quickly as pesticides without harming beneficial species. Future trials are planned to test the technique on mosquitoes, ensuring no risks to humans or other non-target species. This approach could transform pest management and offer hope for healthier communities and a more sustainable future.
