Consecuencias demográficas del sitio de nidificación en la hormiga cortadora de hojas Acromyrmex lobicornis: un enfoque utilizando modelos matriciales

Ecología Austral, 2003
Utilizando modelos matriciales, analizamos cómo las características del sitio de nidificación, al determinar diferentes tipos de hormigueros, influyen sobre la demografía de la hormiga cortadora Acromyrmex lobicornis en el noroeste de la Patagonia.

Foraging and nest maintenance activity of the leafcutter ant Acromyrmex lobicornis (Hymenoptera: Formicidae) in an organic vineyard in the Monte desert of Mendoza, Argentina

Revista de la Sociedad Entomológica Argentina, 2021
Exclusive to the Neotropical region, leaf cutter ants are considered agricultural pests, although they can also have a positive effect on plants. In Mendoza vineyards, vegetal biodiversity is minimal, therefore they cut off this plant as a feeding resource.

To be or not to be faithful: flexible fidelity to foraging trails in the leaf‐cutting ant Acromyrmex lobicornis

Ecological Entomology, 2012
1. Ants using trails to forage have to select between two alternative routes at bifurcations, using two, potentially conflicting, sources of information to make their decision: individual experience to return to a previous successful foraging site (i.e. fidelity) and ant traffic.

Potential of nanostructured alumina for leaf‐cutting ants Acromyrmex lobicornis (Hymenoptera: Formicidae) management

Austral Entomology, 2017
AbstractThe present study assessed the contact toxicity of nanostructured alumina (NSA) and compared it to that of diatomaceous earth (DE) on workers of Acromyrmex lobicornis. Laboratory and field bioassays were also conducted to assess whether ants avoid NSA particles. Nanostructured alumina was more toxic to ants than DE (LC50 for NSA = 0.14 mg/g; CI

Ants as Indicators in Brazil: A Review with Suggestions to Improve the Use of Ants in Environmental Monitoring Programs

Psyche: A Journal of Entomology, Volume 2012, Issue 1, 2012., 2012
We describe the use of ants as indicators in Brazil, based on a critical review of published articles. The analysis of fifty‐eight papers, encompassing a range of almost 25 years, indicates an increased number of studies using ants as indicators in the last decade. Among the parameters analyzed in the papers, species composition is the most suitable to

Specialized Fungal Parasites and Opportunistic Fungi in Gardens of Attine Ants

Psyche: A Journal of Entomology, Volume 2012, Issue 1, 2012., 2012
Ants in the tribe Attini (Hymenoptera: Formicidae) comprise about 230 described species that share the same characteristic: all coevolved in an ancient mutualism with basidiomycetous fungi cultivated for food. In this paper we focused on fungi other than the mutualistic cultivar and their roles in the attine ant symbiosis.

Potential of alternative control of leaf‐cutting ants using essential oils: A systematic review

Agricultural and Forest Entomology, Volume 27, Issue 4, Page 497-511, November 2025.
Abstract Leaf‐cutting ants (LCAs) are abundant and cause considerable damage to agricultural and forest crops in the Neotropical region and are commonly controlled using sulfluramid‐based ant baits. However, this active ingredient is a precursor of perfluorooctane sulfonic acid (PFOS), a persistent, human‐made pollutant that poses serious environmental

Phylogenomic approach to integrative taxonomy resolves a century‐old taxonomic puzzle and the evolutionary history of the Acromyrmex octospinosus species complex

Systematic Entomology, Volume 50, Issue 3, Page 469-494, July 2025.
A comprehensive, integrative study approach combining morphology, population genetics, phylogenetics and biogeography revealed that the Acromyrmex octospinosus species complex consists of two species: A. octospinosus and its social parasite A. insinuator.
