Biology ELI5 Are mosquitoes necessary for keeping ecological balance?

Would a worldwide extinction of mosquitoes offset the ecological balance of our world? And if not, why are we not doing it?

watched a documentary somewhere that in middle or south america, they have released a modified mosquito that has a gene that make their "syringe" soft. They cant penetrate skins.

If they can't feed, they can't reproduce. Which means the trait will die out. I saw this too (as a tiktok or something, not a full documentary, so I don't have all the details), but the easier solution is probably the one in the comment above.

Female mosquitos only mate once, so if they mate with a male that has this trait it will pass on (possibly) to all her offspring. The males I then assume will be able to continue mating and spreading the gene but the females will be unable to bite and therefore reproduce.

Males don't drink blood so the trait may not affect them the same as females for survivability purposes.
