EntomoBrasilis, 2016 Resumo. As formigas-cortadeiras, Atta e Acromyrmex, são consideradas as principais pragas no sistema agroflorestal da Região Neotropical. Isso porque cortam material vegetal que servirá de alimento ao fungo simbionte que elas cultivam.

Patogenicidade de isolados de três fungos entomopatogênicos a soldados de Atta sexdens sexdens (Linnaeus, 1758) (Hymenoptera : Formicidae) Pathogenicity of isolates of three entomopathogenic fungi against soldiers of Atta sexdens sexdens (Linnaeus, 1758) (Hymenoptera : Formicidae) [PDF]
Revista Árvore, 2005 As formigas cortadeiras atacam diversas culturas agrícolas, pastagens e os reflorestamentos, atuando sobre muitas espécies vegetais. O presente trabalho teve por objetivo avaliar a patogenicidade dos fungos Beauveria bassiana (isolados AM 9 e JAB 06 ...

First-year nest growth in the leaf-cutting ants Atta bisphaerica and Atta sexdens rubropilosa [PDF]
Sociobiology, 2014 The majority of ants construct nests underground to maintain environmental conditions favorable to the development of immature and adult individuals. But little is known about nest growth.

Preferences and differences in the trail pheromone of the leaf-cutting ant Atta sexdens sexdens (Hymenoptera: Formicidae) [PDF]
European Journal of Entomology, 2006 The amount of the trail pheromone substance, 3-ethyl-2,5-dimethylpyrazine, of the leaf-cutting ant Atta sexdens sexdens (Hymenoptera: Formicidae) increases with increasing size of the ant from 0 to 35 ng per individual. The compounds 2,5-dimethylpyrazine

Directional vibration sensing in the leafcutter ant Atta sexdens. [PDF]
Biol Open, 2017 ABSTRACT Leafcutter ants communicate with the substrate-borne component of the vibratory emission produced by stridulation. Stridulatory signals in the genus Atta have been described in different behavioural contexts, such as foraging, alarm signalling and collective nest building.

Distinct and enhanced hygienic responses of a leaf-cutting ant toward repeated fungi exposures. [PDF]
Ecol Evol, 2022 The leaf‐cutting ant Atta sexdens discriminates between different antagonistic fungi and apply distinct responses to remove them from the fungus garden. Also, successive exposures to the same antagonist increase sanitization in the fungus garden.

Three phylogenetically distinct and culturable diazotrophs are perennial symbionts of leaf-cutting ants. [PDF]
Ecol Evol, 2021 In leaf‐cutting ant pests, an obligate mutualistic basidiomycete mediates the ants’ nutrition with carbons from vegetal matter using a fermenter‐like system inside the nest, called a “fungus garden.” Diazotrophs such as Enterobacteriales in the fungus garden and intestinal Rhizobiales were proposed to mediate the incorporation of atmospheric nitrogen ...

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

Termite Vibration Sensing: The Chordotonal Organs and Their Appendages. [PDF]
Ecol EvolThis study investigates how termites use their legs and antennae as vibration‐sensitive sensory organs, comparing them to ants, their eusocial predators. Termite appendages are morphologically adapted to detect lower‐frequency, wood‐borne vibrations, enhancing their foraging and predator avoidance abilities. These findings suggest that termite legs may
