Argentine ants are the ones I know of that do aphid and scale farming 
around here. They are really aggressive little buggers and are known to 
have caused the extinction of a species of butterfly whose larvae were 
previously tended by native ants but the Argentine guys kill all the 
native ants. The problem with them is that there was a small genetic 
stock that took root here so it's just one big megacolony. In Argentina 
they fight among their own neighboring colonies and keep balanced that 
way but here they just wipe everything else out.
