Fungos Filamentosos Associados às Espécies Atta sexdens (Linnaeus) e Atta laevigata (F. Smith) (Hymenoptera: Formicidae)

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.

Variação espaço-temporal na atividade forrageira da Saúva (Atta laevigata) [PDF]

Acta Amazonica, 2002
Na Amazônia, a regeneração natural da floresta em pastos e cultivos abandonados pode ser afetada pelas saúvas, pois estas são importantes predadoras das plântulas e das sementes das espécies arbóreas que eventualmente ali se estabelecem.

Foraging by predatory ants: A review. [PDF]

Insect Sci
This review focuses on ecological and behavioral characteristics of foraging in ants showing the wide diversity of cases. Most ants can feed on sugary substances, but some ground‐nesting species are strict predators. Except army ants during the nomadic phase, they are central‐place foragers that can recruit nestmates when necessary. They prey mostly on

Does Atta laevigata (Smith, 1858) act as Solanum lycocarpum seed dispersers?

Sociobiology, 2016
Ants can act as seed dispersers, modifying their distribution, affecting the reproductive success and the vegetation spatial structure. The leaf-cutting ants function, as dispersers of non-myrmecochorous plants, is little known.

Characterization of the Mandible Atta Laevigata and the Bioinspiration for the Development of a Biomimetic Surgical Clamp [PDF]

Materials Research, 2017
Approximately thousand years ago it was reported the use of mandibles of ants for suture. In this sense, bioinspired components, as absorbable surgical clamps, can be designed. This study is aimed to characterize the mandible of the ant Atta laevigata in
