US researchers have created genetically-modified mosquitoes resistant to a malaria parasite, raising the possibility of one day stopping the spread of the disease, a new study says.

The study suggested that when feeding on malaria-infected blood,
"transgenic malaria-resistant mosquitoes have a selective advantage
over non-transgenic mosquitoes," the authors wrote.
The genetically-altered insects survived in greater numbers and
laid more eggs. After nine generations, 70 percent of the
mosquitoes were genetically-modified compared to 50 percent at the
outset of the experiment, Marcelo Jacobs-Lorena and his colleagues
Not ready for prime time
Further research was still needed before the altered insects
could be released into the wild, as only a small percentage of
mosquitoes in nature are exposed to malaria, the authors wrote.
