Toxicity of Hydramethylnon to Leaf-cutting Ant Atta sexdens rubropilosa Forel (Hymenoptera: Formicidae)

open access: yesSociobiology, 2013
Since 2009, when sulfluramid was listed in annex B of the Stockholm Convention’s Persistent Organic Pollutants, effort has been made to search for other active ingredients to use in baits for controlling leaf-cutting ants in Brazil.

A Volatile Semiochemical Released by the Fungus Garden of Leaf-Cutting Ants

open access: yesFlorida Entomologist, 2020
The symbiosis between fungi and leaf-cutting ants (Hymenoptera: Formicidae) has aroused the interest of researchers about the mechanism used by ants to select plants.

The spread of non‐native species

open access: yesBiological Reviews, EarlyView.
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

Leaf-cutting ant attack in initial pine plantations and growth of defoliated plants. [PDF]

open access: yes, 2015
The objective of this work was to evaluate the natural attack by Acromyrmex crassispinus in initial Pinus taeda plantations without control measures against ants, as well as the effect of defoliation in seedlings of P. taeda. Evaluations of the attack of

Representation of Thermal Information in the Antennal Lobe of Leaf-Cutting Ants [PDF]

open access: yes, 2010
Insects are equipped with various types of antennal sensilla, which house thermosensitive neurons adapted to receive different parameters of the thermal environment for a variety of temperature-guided behaviors. In the leaf-cutting ant Atta vollenweideri,

The flexible, the stereotyped and the in‐between: putting together the combinatory tool use origins hypothesis

open access: yesBiological Reviews, EarlyView.
ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated

Behavioural effects of juvenile hormone and their influence on division of labour in leaf-cutting ant societies [PDF]

open access: yes, 2016
Division of labour in social insects represents a major evolutionary transition, but the physiological mechanisms that regulate this are still little understood.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Reciprocal genomic evolution in the ant–fungus agricultural symbiosis

open access: yesNature Communications, 2016
Attine ants, including the leaf-cutting ants, cultivate fungi as their sole source of food. Here, Nygaard et al. use whole genome and transcriptome sequences from seven ant species and their fungal cultivars to reconstruct the reciprocal genetic changes ...

Mutualistic interactions between ants and fungi: A review

open access: yesEcology and Evolution, 2023
The large amount of dead plant biomass caused by the final extinction events triggered a fungi proliferation that mostly differentiated into saprophytes degrading organic matter; others became parasites, predators, likely commensals, and mutualists ...
