Glow-in-the-dark mosquitoes to battle malaria

This bit of news is just for fun: our brilliant American scientists are working on mosquitoes with glow-in-the-dark eyes to help us battle disease.

Yes, this is for real!

So the genetically engineered "glowing eyes" serve no purpose other than to help the scientists distinguish different "breeds" of mosquito (apparently creating a stripe on their backs or something wasn't an option) but overall the news is good -- it looks like a new genetically modified mosquito type might not only be resistant to carrying the parasite that causes malaria, but it's also hardier and has a higher survival rate than the "common" mosquito found in parts of Africa where malaria is the most prevalent. The thought seems to be that someday they will attempt disease control by introducing this new mosquito into the wild bug population, with the hope that it replaces the "old" mosquitoes and malaria infections drop.

So I see the thought process here, but something is wrong with this plan... (even if it does make them easier to swat in the dark).
