We sampled colonies of leaf-cutter ants (Atta sexdens rubropilosa) inside and outside of São Paulo.Our samples included four urban colonies near the University of São Paulo and five rural colonies distributed along a north-westerly transect (Fig. 1).We only collected ants that were walking along trails, carrying leaves or pieces of leaves.Nest ventilation should be particularly relevant for the huge colonies of leaf-cutting ants, genus Atta.

The amount of vegetation cut from tropical forests by the Atta ants alone has been estimated at 12-17 percent of all leaf production. Grass-cutting species accomplish similar feats: one species, A. capiguara, reduces the commercial value of pasture land in Brazil and Paraguay by as much as 10 percent.The attini tribe comprises fungusgrowing ants, such as the basal Apterostigma and other more specialized genera, including the higher attine and the ones that cut the fresh plant tissue (Atta and Acromyrmex), maintaining an obligatory mutualistic relation with the fungus Leucoagaricus gongylophorus, which serves as a food source for …especially ant-attended Homoptera, and negative association with others which may be heavily preyed upon.

Proatta butteli. Forel, 1912. Specimen labels. The only species in its genus, Proatta butteli is found in southeast Asia and is strikingly similar in appearance to New World Attine species. Unlike the Attines, Proatta butteli is a predator and scavenger. Their prey includes isopods, centipedes and a variety of insects, including other ant species.In the fungus-growing ant genus Atta, foundress queens nourish their brood and incipient fungus gardens with nutrients derived from trophic eggs. We discovered a third kind of egg laid by Atta foundresses in addition to reproductive and trophic eggs. We use fluorescent microscopy to show that this third type of eggs represents reproductive eggs that are unviable and fail to develop. Unviable ...…
