There are some varieties of ants capable of "agriculture", e.g. dairing ants farming aphids and leaf-cutting ants farming fungus.
How is the knowledge about the techniques involved passed between generations (in the case of dairing aphids I mean e.g. milking the the aphids to get honeydew, and protecting the aphids)? In short, is it more "genetic" (so that lab-cloned ants are capable of it) or is it more part of "culture", i.e. younger ants mimicking the older ones? I'd be mostly interested in answers with references to relevant experimental research.
