I know there is some science backing the general approach, but doesn't evolution tend to pressure the virus developing different vectors, when faced with eradication? There is probably a good subset of the 2997 other species that could serve the purpose.

What does evolution “pressuring” mean? Either the organism (or virus) has sufficient chances to randomly mutate a a trait that enables it to survive, or it goes extinct.

Well, I meant https://en.wikipedia.org/wiki/Evolutionary_pressure

Think of a population as holding at any given time a number of individuals carrying mutations. The fringe mutations, such as being able to be hosted by a different type of mosquito (say, better survivability in the host) don't provide much of a benefit to survival. But if the default host population goes away, those mutations become super valuable and will be selected.

See https://www.scientificamerican.com/article/transgenic-mosqui... for a discussion on this topic.

Probably depends on how fast the species is eradicated.
