Leaf-Cutting Ants, Biology and Control

2013
Leaf-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, 1997
Leaf-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, 2001
Hygienic 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.

Stridulation in Leaf-Cutting Ants

Science, 1965
The 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.

Occurrence of killer yeasts in leaf-cutting ant nests

Folia Microbiologica, 2002
Killer 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

2003
Ants 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, 1987
Abstract 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 ...

Interspecific aggression in leaf-cutting ants

Animal Behaviour, 1979
Abstract Interspecific aggression between leaf-cutting ants is described both in the field and in the laboratory, and a species hierarchy in fighting success is postulated. As opponents get bigger, however, the dominant species takes longer to attack, until opponents are much larger when the usually dominant species is defeated.
