These insects don’t protect anything, mosquitos and tsetse flies haven’t been a valid reason to avoid settling an area since the Colombian Exchange. It isn’t difficult to drain a marsh.
Any precious little swamp (where all the wondrous animals within are also being preyed upon by mosquitoes & eg tsetse flies) is still going to be drained if it makes economic sense, and it typically does!
The only place where mosquitoes and tsetse flies protect “habitats” are in the most backwater, poorest, least developed regions of the planet where all the millions of deaths are as well, it figures their lives don’t matter/can be taken advantage of in the name of “nature”.
