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.

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.

The Natural History of Leaf-Cutting Ants
2003No one can give us an exact number of animal species living on earth today, but all biologists agree that millions more species exist than the approximately 1.5 million that have been described so far. Quantitative faunistic investigations in many habitats suggest about 8 million extant species; other assessments claim 30 million species or even more ...

Use of a Sound-Based Vibratome by Leaf-Cutting Ants
Science, 1995Leaf-cutting ants harvest fresh vegetation that they then use as food for symbiotic fungi. When cutting leaf fragments, the ants produce high-frequency vibrations with a specialized organ located on the gaster. This stridulation behavior is synchronized with movements of the mandible, generating complex vibrations of the mandibles. The high vibrational

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 ...

Interspecific aggression in leaf-cutting ants
Animal Behaviour, 1979Abstract 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.

The Economic Importance of Leaf-Cutting Ants
2019The economically important leaf-cutting ants are restricted to the genera Atta and Acromyrmex, are fungus-growing ants of the Tribe Attini and are found only in the New World. In a questionnaire survey of 27 countries, J. M. Cherrett and D. J. Peregrine reported that 47 agricultural crops suffered leaf-cutting ant damage, and a survey of the literature

Diploid male production in a leaf‐cutting ant
Ecological Entomology, 20101. In haplodiploid social insects where males are haploid and females are diploid, inbreeding depression is expressed as the production of diploid males when homozygosity at the sex‐determining locus results in the production of diploid individuals with a male phenotype.

History of the Leaf-Cutting Ant Problem
2019Pest species of leaf-cutting ants are restricted to the two genera Acromyrmex and Atta and, like the whole tribe Attini to which they belong, they are confined to the New World approximately between the latitudes 33°N and 44°S. Certainly pest problems in the species-poor areas of Central and North America are much less acute than they are in the south.
