    BAMAKO, Mali, Jan. 12 (UPI) -- Researchers in Mali have discovered a new hybrid mosquito -- a so-called "super mosquito" -- that is unaffected by bed nets treated with insecticides.

But scientists with the University of California, Davis say that those same interventions have altered the evolutionary landscape, encouraging the sexual cooperation of two previously isolated mosquito species.

    Anopheles gambiae -- one of the mosquito species most heavily responsible for the spread of malaria in West Africa -- has been mating with small pockets of another species, Anophele coluzzii...
