From the first article, it mentioned that we have eradicated similar disease vectors like screwworm and melon fly before, so what have been the environmental impact of that so far?

What percentage of the next level up on the food chain lives off mosquitoes? What percentage lives of screwworms and Melon flies? I have no idea about the answers, but if there is a significant difference there then that might be where trouble could come from. The problems really start at the reservoir hosts, the mosquitoes are just the transmitters. Controlling the reservoir hosts might be more feasible than eradicating 40 species of mosquito, it sounds like a very ambitious plan to me. Panama had only 2 problematic species around the (prospective) canal zone. Eradicating those mosquitoes to allow construction of the canal to proceed without the crews succumbing to Malaria or Yellow Fever was a huge success: http://en.wikipedia.org/wiki/Health_measures_during_the_construction_of_the_Panama_Canal http://en.wikipedia.org/wiki/Health_measures_during_the_cons...

  Does the fact that we have done this thousands of times now, accidentally, without any knowledge of the species being affected, make it any better? Does the fact that essentially all of the interspecific dependencies in the temperate and Arctic zones have shifted completely in response to simple climate change since the last glaciation, make it any better?

After all, tens of thousands of species have gone extinct in our watch. Who knows how many of those were due to having done "this". >Does the fact that essentially all of the interspecific dependencies in the temperate and Arctic zones have shifted completely in response to simple climate change since the last glaciation, make it any better? Nope. And I seriously doubt they have shifted "completely".

  The malarias that infect humans pretty much only infect humans. I guess it isn't strictly true, but infected humans are certainly the primary reservoir for most of them (maybe you meant humans when you said reservoir hosts, I'm not sure). The last time I saw something about sterile male mosquitoes it was in the context of releasing them in regions with high rates of malaria, to cut down on the spread, not in the context of eradication.
