Systematik
Unterfamilie: Myrmicinae
Gattung: Acromyrmex
Wissenschaftlicher Name
Acromyrmex

Acromyrmex ist eine Gattung der Attini und gehört zur Unterfamilie Myrmicinae. Ein bekannter Vertreter ist Acromyrmex octospinosus. Siehe auch: Atta.

Die Kolonien sind bei manchen Arten deutlich kleiner als die von Atta spp.. Auch kommen Acromyrmex-Arten nicht nur in tropischen Bereichen vor, sondern können fast bis in die gemäßigte Zone Südamerikas vordringen, wo sie recht niedrige Temperaturen ertragen. Siehe Acromyrmex spec..

Laut der folgenden Veröffentlichung sind Arbeiterinnen von Acromyrmex fertil und können Eier legen, aus denen sich Männchen entwickeln. Dies geschieht regelmäßig nach dem Tod der Königin.

Scientists at the University of East Anglia, have shown that fungus-farming ants are using multiple antibiotics as weed killers to maintain their fungus gardens. Research led by Dr Matt Hutchings and published today in the journal BMC Biology shows that ants use the antibiotics to inhibit the growth of unwanted fungi and bacteria in their fungus cultures which they use to feed their larvae and queen.

These antibiotics are produced by actinomycete bacteria that live on the ants in a mutual symbiosis.
