I didn't read that as eliminating an entire niche in the ecosystem. They aren't in danger of extinction, and simply not introducing new modified mosquitos if the numbers do indeed drop too far.
We already control mosquito threats via population control, as we do for many animals.
People don't like getting bitten by mosquitoes. More, they carry disease, and cause injuries which often get secondary infections. I get why we want them gone.
But it is the WOODS. It is their place, and they're an essential part of a very complex system. The trout need them, the plants need them, the bats need them, they fulfill a role to the woods.
We can try to reduce the number of mosquitoes to a level which no longer bothers people, but what percentage is that? All too easy, for non-thinking, non-caring people to blithely quip "0%, ha, hahhh, Good Riddance!"
And even if we can get a majority of people to be insightful enough to say 40%, a number which allows them to fulfill their essential roles to the ecosystem, then they still represent a problem for people in the spread of disease, and minor injuries which lead to secondary infections.
This is NOT a reasonable approach. You're addressing the problem in the wrong "Spatial Context". You're trying to say, "Let's control the number of mosquitoes in the Woods, in general, over the whole of their ecosystem niche range".
What we should be doing, is using the new tech and Genetech to create a form of mosquitoes which are altered as little as possible, but have some element which makes them self-exclude themselves from the very small comparatively space around each human being... ONLY!
If we want the enjoy the beauty and bounty of the Woods, we need to leave it alone, except for the minimal a interface zone around each of US as we move through the woods.
Just a better form of high tech, flexible, transparent, mosquito netting, or perhaps some sort of LED flash light UV light repellant would make sense.
A general reduction of the percentage of mosquitoes in the woods over all is just the kind of heavy handed, thoughtless, short sighted approach that have used to our regret in the past.
Change the woods as little as possible, should be our general approach!
