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.

Collection and Long-Term Maintenance of Leaf-Cutting Ants (Atta) in Laboratory Conditions.

Journal of Visualized Experiments, 2022
Ants are one of the most biodiverse groups of animals on the planet and inhabit different environments. The maintenance of ant colonies in controlled environments enables an enriched comprehension of their biology that can contribute to applied research.

Amoimyrmex Cristiano, Cardoso & Sandoval, gen. nov. (Hymenoptera: Formicidae): a new genus of leaf‐cutting ants revealed by multilocus molecular phylogenetic and morphological analyses

, 2020
Leaf‐cutting ants (genera Acromyrmex and Atta) are the most important herbivores in the Neotropical region. Within the genus Acromyrmex, the species and subspecies Acromyrmex striatus, Acromyrmex silvestrii subsp.

Leaf‐cutting ants negatively impact the regeneration of the Caatinga dry forest across abandoned pastures

Biotropica, 2020
The mechanisms affecting forest regeneration in human‐modified landscapes are attracting increasing attention as tropical forests have been recognized as key habitats for biodiversity conservation, provision of ecosystem services, and human well‐being ...

Hydrolytic enzymes of leaf-cutting ant fungi

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2009
The 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.

Economic Injury Level and Economic Threshold as required by Forest Stewardship Council for management of leaf‐cutting ants in forest plantations

, 2020
The most commonly used method to control insect pests, such as leaf‐cutting ants (LCA) in forest plantations, is the application of chemical insecticides, but their use was forbidden in plantations certified by the Forest Stewardship Council because of ...

Digestive Physiology of Leaf-Cutting Ants

2019
Digestion 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

Tree seedling responses to leaf‐cutting ants herbivory in Atlantic Forest restoration sites

Biotropica, 2020
Leaf‐cutting ants (LCA) are generalist herbivores capable of causing severe plant damage. Negative impacts of ant herbivory vary according to the density of nests and availability of palatable plants; however, it is not yet clear how these herbivores ...
