David's Comment: I suspect the colony automatically senses the need to change population dynamics and these chemical changes are also automatic at that point.

Of course you suspect that ants do it automatically. You hate the very idea that small organisms might know what they're doing! -We don't change DNA epigenetically by injections of humans. The point of the article is ant have onboard population controls. Why are they present? Did they invent those? Or were they supplied?
