We can't fully predict what the consequences of erasing a species as numerous as this would be, so experimentation is the key. Whe should see what happens with a smaller sample ecosystem first.
Also, it's possible that this change could take decades or centuries, given how many mosquitos there are. It wouldn't be like nuking them all with a press of a button, as we obviously couldn't affect every single male mosquito alive.

From a scientific point of view, it's a great opportunity to learn. No, it would not suddenly cause overpopulation, and even if it did, overpopulation is a problem that fixes itself.
We couldn't possibly distribute food evenly across the globe anyway (we certainly aren't doing so now) so we wouldn't all just suddenly starve and die. Even today, some of us could certainly consume a little less recources.

Also, one more thing. CAV's first post reminded me that I could point this out as well.

This act, erasing a species that causes human deaths, would not interfere with our "natural evolution" in any way. "Natural" is simply a word that we made up, literally every single thing in existense is natural, man made or not. Therefore, there is only evolution, and using our brains to solve problems is a part of it.
To further explain my point: We cannot interfere with evolution, unless we erase all variables from our lives. Evolution doesn't have a goal, it's not an entity or a conscious process. It doesn't make "perfect" beings, it and doesn't even make beings "better".
Evolution of biological life is flora and fauna physically adapting to their situation through the trial and error of random mutations, and it all goes according to the laws of physics.

In some way, the "weak" die and the "strong" survive, always. No matter what happens. Think of it as a constant flow instead of linear progress. At any given time our species is different, ever changing. Old man dies: humanity is a little bit younger on average, sick man dies: humanity is a little bit healthier on average, etc.

I am for this idea, if it works to our favor. We just need to find out if it does before we make it happen.
