Since the goal is to rid ourselves of malaria, are there more sophisticated ways to do this that don't involve permanently eradicating some or all species of mosquitoes?
I'm sure I read, perhaps mid 1990's in a New Scientist article, a proposition along the lines of:
1. obtain a good sampling of a/some mosquito species - keep them in a sealed greenhouse somewhere, ensuring they have access to clean blood (ie. no pathogens we care about)
2. eradicate them in the wild - at the time the expectation was a 'terminator' style gene that, once introduced into populations would, after say a dozen or so generations, lead to an exclusively infertile population, resulting in extinction
3. release the pathogen-free mosquitoes back into the environment - presumably after ensuring pathogens were no longer in the population, which I suppose means at least one generation of hosts - so it could be some decades.
The idea was appealing because it means if we missed something fundamental during phase 2, it'd be possible to re-populate quickly, it could be repeated periodically if needed, and it could be performed on regional levels with good effect, especially if you toned down your expectations to 'drastically reducing prevalence of pathogens' rather than 100% eradication.
