Spermless mosquitoes could halt malaria spread: study
The Independent | August 13, 2023Malaria is spread to humans by female mosquitoes who suck blood in order to help their offspring grow, but British scientists said Monday that introducing spermless males could halt the deadly disease.
Since the females of the species Anopheles gambiae sensu stricto, the main type responsible for spreading malaria in Africa, mate only once in their lives, the discovery could have broad implications for a disease that kills nearly 800,000 people per year. paras netticasino
"This study strongly suggests that they cannot tell the difference between a fertile and a spermless mate," said Flaminia Catteruccia, lead author of the study in the Proceedings of the National Academy of Sciences.
Scientists created 100 sterile males by injecting a protein into mosquito eggs that disrupted the development of the males' testes, but did not affect any of their other behaviors or sexual functions. freispiele
