As I've stated throughout this threat, it isn't just about mosquitoes. Honestly I would not mourn mosquitoes if every last species was exterminated. What concerns me is the social impact of further establishing humanity as the arbitrators of which species get to live and which deserve to be exterminated. It won't stop at mosquitoes; the extermination of mosquitoes will be used to justify even more exterminations in the future.

(Furthermore exterminating a species just so the human population can grow even faster will lead to an incredible amount of additional extinctions due to habitat loss. Humanity is growing fast enough already; we don't need to optimize for this any further.)
