Stridulation in Leaf-Cutting Ants
Science, 1965The leaf-cutting ant Atta caphaloes L. stridulates whenever it is prevented from moving freely. Although audible to the human ear, the airborne sound produced has its main energy concentrated between 20 and 60 kilocycles per second.

Hydrolytic enzymes of leaf-cutting ant fungi
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2009The production of enzymes and the colonization of leaves by Leucoagaricus gongylophorus were investigated to further understand the digestive interactions of leaf-cutting ant colonies. The enzymes detected were indicative of a saprophytic origin of this fungus, producing all the enzymes necessary for plant tissue breakdown.

Digestive Physiology of Leaf-Cutting Ants
2019Digestion depends, among other factors, on the quality of the ingested food and on the digestive enzyme activities of the alimentary tract. The studies carried out on the digestive physiology of Ac.octospinosus are important for research on the development of new methods of control. The digestive system of the larvae of Ac.octospinosus is comparable to

Leaf-Cutting Ants, Biology and Control
2013Leaf-cutting ants (Formicidae, Myrmicinae, Attini) are found on the American continent and in the Caribbean and are known to live in symbiosis with a fungus. Among Attini tribe, Atta and Acromyrmex are the two genera, which commonly depend on fresh plant leaves and other plant material for their fungal garden.

Evolutionary aspects of ant-fungus interactions in leaf-cutting ants
Trends in Ecology & Evolution, 1997Leaf-cutting ants are highly successful herbivores because they are able to use a wide variety of plants as food The workers harvest and process plant material to be used as substrate for a fungus on which they feed. New hypotheses concerning the evolution of the ant-fungus relationship have now been proposed. Although the relationship between the ants

Waste management in leaf-cutting ants
Ethology Ecology & Evolution, 2001Hygienic behaviour is an important aspect of social organisation because living in aggregations facilitates the spread of disease. Leaf-cutting ants face the additional problem of an obligatory dependency on a fungus, which itself is also susceptible to parasites.

Occurrence of killer yeasts in leaf-cutting ant nests
Folia Microbiologica, 2002Killer activity was screened in 99 yeast strains isolated from the nests of the leaf-cutting ant Atta sexdens against 6 standard sensitive strains, as well as against each other. Among this yeast community killer activity was widespread since 77 strains (78%) were able to kill or inhibit the growth of at least one standard strain or nest strain.

Seed Dispersal by Leaf-Cutting Ants
2003Ants as dispersal agents represent a well-studied topic mainly in the case of myrmecochorous plants which provoke seed removal by the ‘elaiosome’, a seed-born appendage serving as protein and oil-rich food reward for the ants (Beattie 1985). This mode of dispersion is common among herbs of temperate mesic forests in the Northern Hemisphere, and woody ...

Orientation in leaf-cutting ants (Formicidae: Attini)
Animal Behaviour, 1987Abstract The cues used for orientation on chemical trails by laboratory colonies of Atta cephalotes, Atta laevigata and Acromyrmex octospinosus were studied. The ants used cues other than the odour trail itself when homing. When cues gave contradictory information, Atta workers used them in a certain hierarchy: presence of an odour trail ...
