This is hypothetical. Even if somebody indiscriminately releases millions of genetically modified death-skeeters, it would not make mosquitoes extinct. There are more than 3,500 species of mosquito, for one. Also, from the BBC article, "Would it be wrong to eradicate mosquitoes?
The question is likely to remain hypothetical, whatever the level of concern over Zika, malaria and dengue. Despite the success of reducing mosquito numbers in smaller areas, many scientists say knocking out an entire species would be impossible.
"There's no silver bullet," says Hawkes. "Field trials using GM mosquitoes have been a moderate success but involved releasing millions of modified insects to cover just a small area.
"Getting every female mosquito to breed with sterile males in a large area would be very difficult. Instead we should be looking to combine this with other techniques."
