OCORRÊNCIA DE FORMIGAS CORTADEIRAS NA REGIÃO DA DEPRESSÃO CENTRAL DO ESTADO DO RIO GRANDE DO SUL [PDF]
Ciência Rural, 2002 Com o objetivo de identificar as espécies de formigas cortadeiras que existem na região da Depressão Central do Estado do Rio Grande do Sul, de verificar sua predominância e distribuição geográfica, realizou-se um levantamento em 51 municípios.

Ecological Entomology, 2012 1. Ants using trails to forage have to select between two alternative routes at bifurcations, using two, potentially conflicting, sources of information to make their decision: individual experience to return to a previous successful foraging site (i.e. fidelity) and ant traffic.

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.

Revista de la Sociedad Entomológica Argentina, 2021 Exclusive to the Neotropical region, leaf cutter ants are considered agricultural pests, although they can also have a positive effect on plants. In Mendoza vineyards, vegetal biodiversity is minimal, therefore they cut off this plant as a feeding resource.

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.

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.

Psyche: A Journal of Entomology, Volume 2012, Issue 1, 2012., 2012 Parental care is rare in most lower vertebrates. By selecting optimal oviposition sites, however, mothers can realize some benefits often associated with parental care. We found three ovoid reptilian eggs within a mature nest of a relatively basal fungus‐growing ant, Apterostigma cf. goniodes (Attini), in central Panama. In laboratory colonies, A.

The Effect of nest Size and Species Identity on Plant Selection in Acromyrmex Leaf-Cutting Ants
Sociobiology, 2018 Leaf-cutting ants are key organisms because their role as primary consumers and potential agricultural pests. However, their foraging ecology was mostly studied as response of extrinsic factors such as climate and plant species traits.
