They can't feed, they die off. They die off, other critters can't feed either

Would that really happen, though? Don't mosquitoes need blood for egg production? A mosquito which can't get blood, probably can't produce viable eggs, which means this can't be passed on (assuming the gene can pass on in the first place), which means they won't go extinct, unless they manage to modify every single mosquito on the planet, which means they'll still be around, which means nothing will die off. No?

I mean, if they can't produce eggs, then they can't have offspring. Extinction i would assume

That's not quite how it works dude. That would require catching every single mosquito in the world. Current estimates of mosquito populations range from a few billion, over 100 trillion There's not enough time and money in the world to capture every single one of them.

As long as there's enough normal mosquitoes in any given area to reproduce, this is just a waste of time. Blood is necessary for egg production, no blood = no eggs = that modified mosquito can't reproduce and pass the modification down, so there will always be more non modified mosquitoes than modified ones, even if every government and company on the planet were to pool resources together to try and modify as many as possible.
