With climate change driving up global temperatures, "mosquito-spread diseases" like malaria .. are now showing up in he U-S. 

Researchers at UC San Diego are working on genetic modifying technology .. that could eventually wipe-out much of the world's "malaria-carrying mosquitoes." 

UCSD biologist Omar Akbari tells KNX .. they're genetically altering male mosquitoes - to take aim at their female counterparts.

Akbari says .. they are honing in on just a few mosquito species - that carry and spread malaria .. so it's NOT about wiping-out ALL female mosquitoes. 

For the first time in at least 20-years,  malaria cases are spreading in states like  Florida,  Texas  and  Minnesota.
