Scientists develop STD that could wipe out mosquitoes
- Scientists have developed genetic tools and a "sexually transmitted disease" using a deadly fungus to combat disease-carrying mosquitoes, primarily targeting females – which are responsible for biting – to reduce their lifespan and fertility.
- The fungus, Metarhizium, is sprayed on male mosquitoes and produces neurotoxins that kill females, while also making the mosquitoes more susceptible to insecticides.
- Scientists have also been able to genetically alter male mosquitoes to produce venom proteins in their semen that can reduce the lifespan of females.
- Mosquitoes, while serving as a food source and pollinators, are the world’s deadliest animal, responsible for transmitting diseases like malaria, West Nile virus, and eastern equine encephalitis.
- Bioethicists and environmental philosophers have raised concerns about the ecological impact of potentially eradicating mosquitoes, considering their role in ecosystems and the broader biodiversity crisis.
