I’m not sure, but perhaps eradicating the Aedes aegypti is enough to prevent most of the dengue transmission.
And the Aedes albopictus (Tiger mosquito) is also a non native specie in Brazil, so it’s probably a good idea to eradicate it too, perhaps using the same method. http://en.wikipedia.org/wiki/Aedes_albopictus
