Coping with temperature extremes: thermal tolerance and behavioral plasticity in desert leaf-cutting ants (Hymeno ptera: Formicidae) across an altitudinal gradient [PDF]
, 2020 Current approaches to assess and predict the impact of climate warming on ectotherms are largely based on their physiological sensitivity to temperature.

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

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

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

Psyche: 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.

Leaf‐Cutter Ant Parasitoids: Current Knowledge
Psyche: 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.

Gayana (Concepción), 2001 En la estructura social de formicidos se distingue una casta de individuos sexuados encargada de la reproduccion y una casta de individuos esteriles u obreras encargada del resto de las tareas de la sociedad, tales como cuidado de la prole, construccion del nido y defensa.

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