Variabilidade genética interespecífica em formigas cortadeiras do gênero Acromyrmex que ocorrem no Estado do Rio Grande do Sul Inter-specific genetic variability of leaf cutting ants (Acromyrmex genus) from Rio Grande do Sul State

open access: yesCiência Rural, 2007
São poucos os taxonomistas que atuam na identificação de formigas cortadeiras. Os métodos morfométricos utilizados nem sempre permitem uma identificação confiável, em função do acentuado polimorfismo dentro do mesmo formigueiro.

Potential of alternative control of leaf‐cutting ants using essential oils: A systematic review

open access: yesAgricultural and Forest Entomology, Volume 27, Issue 4, Page 497-511, November 2025.
Abstract Leaf‐cutting ants (LCAs) are abundant and cause considerable damage to agricultural and forest crops in the Neotropical region and are commonly controlled using sulfluramid‐based ant baits. However, this active ingredient is a precursor of perfluorooctane sulfonic acid (PFOS), a persistent, human‐made pollutant that poses serious environmental

The preference for energetic resources is positively associated with predatory activity in ants

open access: yesEcological Entomology, Volume 50, Issue 5, Page 921-932, October 2025.
We found that ants exhibit a stronger preference for foraging for carbohydrates and lipids (energetic nutrients) compared to amino acids. The increase in foraging for energetic nutrients compared to amino acids is positively correlated with foraging in larvae (insect predation). The nutrient preference between foraging for energetic nutrients and amino

Isoenzyme variation in the leaf-cutting ants Acromyrmex heyeri and Acromyrmex striatus (Hymenoptera, formicidae)

open access: yesGenetics and Molecular Biology, 2002
This is the first study of isoenzyme variability in the leaf-cutting ants (Myrmicinae, Attini) Acromyrmex heyeri (Forel, 1899) and A. striatus (Roger, 1863) which are common throughout the southern Brazilian state of Rio Grande do Sul.

Whole genome shotgun phylogenomics resolve the diving beetle tree of life

open access: yesSystematic Entomology, Volume 50, Issue 4, Page 940-974, October 2025.
A new and strongly supported phylogeny of diving beetles (Dytiscidae) is presented using the largest genomic dataset to date. Laccophilinae and Coptotominae + Lancetinae are early diverging lineages excluded from a large monophyletic clade comprising the remaining eight subfamilies. We identify seven remaining problems in the backbone of the phylogeny,
