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

Mapping defoliation by leaf-cutting ants Atta species in Eucalyptus plantations using the Sentinel-2 sensor

International Journal of Remote Sensing, 2020
Leaf-cutting ants are one of the most important pests of eucalyptus plantations and it is essential to monitor and control these insects to avoid damage to wood production.

Artifacts Caused by Leaf‐Cutting Ants of the Genus Atta (Hymenoptera: Formicidae): Postmortem Bite Injuries and the Tearing of Clothes

Journal of Forensic Sciences, 2020
Ants are one of the first insects to find an exposed cadaver and can be present during all stages of decomposition. Although these organisms are not commonly used in postmortem interval estimates, they are to be taken into account on criminal ...

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.

Human disturbance promotes herbivory by leaf‐cutting ants in the Caatinga dry forest

Biotropica, 2018
Anthropogenic disturbances are known to modify plant–animal interactions such as those involving the leaf‐cutting ants, the most voracious and proliferating herbivore across human‐modified landscapes in the Neotropics.

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 ...
