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

open access: yesEcología 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.

Patrones de actividad forrajera y tamaño de nido de Acromyrmex lobicornis (Hymenoptera: Formicidae) en una zona urbana de San Luis, Argentina

open access: yesRevista de la Sociedad Entomológica Argentina, 2012
Diversos factores pueden influir sobre la actividad de forrajeo de las hormigas cortadoras de hojas. Sin embargo, los factores climáticos, especialmente la temperatura, pueden ser considerados los más importantes en las regiones templadas.

Shifts in Chromosome Evolution Rates Shape the Karyotype Patterns of Leafcutting Ants. [PDF]

open access: yesEcol Evol
Modern phylogenetic methods were used to explore how chromosome number and other karyotypic traits vary across species. The focus was on testing whether karyotypic traits follow a Brownian motion model (indicating neutral changes) or are influenced by phylogenetic constraints.This research elucidates the mechanisms underlying chromosomal evolution and ...

Learning through the waste: olfactory cues from the colony refuse influence plant preferences in foraging leaf-cutting ants [PDF]

open access: yes, 2016
Leaf-cutting ants learn to avoid plants initially harvested if they proved to be harmful for their symbiotic fungus once incorporated into the nest.

Leaf-cutting ants facilitation to non-native plants is passed from one generation to the next [PDF]

open access: yes, 2022
In arid environments where soil resources are limiting factors, the presence of soil ecosystem engineers that create new enriched soil habitats can improve the performance of non-native plants growing there.

Diapriinae Wasps (Hymenoptera: Diaprioidea: Diapriidae) Associated with Ants (Hymenoptera: Formicidae) in Argentina

open access: yesPsyche: A Journal of Entomology, Volume 2013, Issue 1, 2013., 2013
We provide an overview of diapriid wasps associated with ants in Argentina and the diversity of interactions they have developed with their hosts. As a result, we report 16 species of nine genera of Diapriinae, two new geographic distributions, three new association records, illustrations, and photographs.

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

open access: yesAustral 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

Leaf‐Cutter Ant Parasitoids: Current Knowledge

open access: yesPsyche: A Journal of Entomology, Volume 2013, Issue 1, 2013., 2013
This review updates and summarizes the current knowledge about the interaction of leaf‐cutter ants and their parasitoids by providing comparable data for Acromyrmex and Atta ants. First, an overview of the relevant aspects of the biology and taxonomy of leaf cutters and of their parasitoids is provided.

Diversity of Species and Behavior of Hymenopteran Parasitoids of Ants: A Review

open access: yesPsyche: A Journal of Entomology, Volume 2012, Issue 1, 2012., 2012
Reports of hymenopterans associated with ants involve more than 500 species, but only a fraction unambiguously pertain to actual parasitoids. In this paper, we attempt to provide an overview of both the diversity of these parasitoid wasps and the diversity of the types of interactions they have formed with their ant hosts.

Eggs of the Blind Snake, Liotyphlops albirostris, Are Incubated in a Nest of the Lower Fungus‐Growing Ant,  Apterostigma cf. goniodes

open access: yesPsyche: A Journal of Entomology, Volume 2012, Issue 1, 2012., 2012
Parental care is rare in most lower vertebrates. By selecting optimal oviposition sites, however, mothers can realize some benefits often associated with parental care. We found three ovoid reptilian eggs within a mature nest of a relatively basal fungus‐growing ant, Apterostigma cf. goniodes (Attini), in central Panama. In laboratory colonies, A.
