Scientists Breed Spermless Mosquitoes In Effort to End Malaria

A new kind of male mosquito Back in April we learned about genetically modified mosquitoes that are equipped with the ability to kill off the malarial parasite so that it cannot be transmitted to humans. Now, scientists have taken another approach. Rather than battle a mosquito's ability to carry malaria, it's battling the male mosquito's ability to carry sperm. BBC reports on the research published in the Proceedings of the National Academy of Sciences . "Insect sterilisation isn't new: scientists have attempted to control the sleeping sickness-carrying tsetse fly by exposing them to radiation to render them sterile. A similar approach has been successfully used against the potatoes weevil in Japan and the tropical screwworm that attacks cattle," reports BBC. However the same tactic has not been shown to work with mosquitoes because the males are too frail to mate with fe...
