A problem is the discussion almost immediately derails into the eradication of all mosquitos, such as almost immediately happened right here. My understanding of these experiments is it is the eradication of particular subspecies of mosquitos, the ones able to transmit malaria, dengue fever, zika etc. And the difference is huge; wipe out a dozen subspecies and their ecological niches will be filled by other subspecies of mosquito.
Correct, there are thousands of species of mosquito that do not feed on human blood. The question is whether a genetic weapon could be made specific enough to target only the blood suckers while sparing the pollinators.
The techniques being looked at only target a single species. To spread, it requires interbreeding between species which is rare, and for the the new species to out compete and spread, which is unlikely since the condition is fatal to the carriers of the genetic modification's next generation.
