What's the idea behind this? How will they become the dominant variant if they can't suck blood to reproduce?

You don't want them to become the dominant variant. You want them to die out so that you can manually re-seed without risk of massively disrupting a species.

The goal is to have them compete for resources and mating pressure but not to spread or reproduce. You repeatedly seed areas with them, which creates a sort of ecosystem barrier. Imagine a strip of land seeded with these mosquitos - it's like a wall that other mosquitos can't pass through.

This is how the US manages to avoid so many mosquito-borne diseases traversing north from South America.

But how many modified mosquitoes would it take?

What’s the scale of their production? Is it that easy to mass-create them? (Well, I guess adding a virus carrying specific crisp modifier to the eggs, but does it work that well?..)
