Phylogenomic reconstruction reveals new insights into the evolution and biogeography of Atta leaf‐cutting ants (Hymenoptera: Formicidae)

Systematic Entomology, Volume 47, Issue 1, Page 13-35, January 2022., 2022
We employ phylogenomic markers (UCEs) to reconstruct the most extensively sampled phylogeny to date for the ecologically dominant leaf‐cutting ant genus Atta, the major herbivore of the New World tropics. The ancestor of Atta arose 8.5 Ma in the North/Central America + NW South America range, and its descendant species rapidly radiated into Neotropical

Three phylogenetically distinct and culturable diazotrophs are perennial symbionts of leaf‐cutting ants

Ecology and Evolution, Volume 11, Issue 24, Page 17686-17699, December 2021., 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 ...

The multidimensional nutritional niche of fungus‐cultivar provisioning in free‐ranging colonies of a neotropical leafcutter ant

Ecology Letters, Volume 24, Issue 11, Page 2439-2451, November 2021., 2021
Free‐ranging leafcutter ants forage nutritionally and chemically diverse plant fragments to fit the requirements of their fungal food crop. However, these foraged plant fragments can also contain nutrients in excess of the cultivar's tolerance, which can limit fungal production.

Isolation and molecular characterization of symbiotic fungus from Acromyrmex ambiguus and Acromyrmex heyeri ants of Rio Grande do Sul State, Brazil

Ciência Rural, 2015
Leaf-cutting ants of the genera Atta and Acromyrmex determine serious agricultural problems and live on symbiosis with Leucoagaricus gongylophorus. The aim of this study is to identify morphological and molecularly, as well as to verify the genotypic ...

Crescimento do fungo simbionte de formigas cortadeiras do gênero Acromyrmex em meios de cultura com diferentes extratos [PDF]

Ciência Rural, 2006
As formigas cortadeiras mostram preferência por algumas espécies vegetais, as quais são constantemente desfolhadas, enquanto outras não são atacadas, embora sejam abundantes e localizadas próximas ao ninho.

The effect of homeopathic preparations on the activity level of Acromyrmex leaf-cutting ants=Atividade de formigas cortadeiras Acromyrmex spp. submetidas a preparações homeopáticas [PDF]

Acta Scientiarum. Agronomy, 2012
The effect of homeopathic preparations on the activities of the leaf-cutting ants Acromyrmex spp. was studied. A field experiment involving ant nests in six experimental areas was performed using a randomised complete block design.
