Trait‐Mediated Indirect Effects of Phorid Flies on Ants

Psyche: A Journal of Entomology, Volume 2012, Issue 1, 2012., 2012
This paper provides a synthesis of the ecological impact of phorid fly parasitoids on ants. We find the most important impact of phorids on ants to be trait‐mediated effects. Phorids diminish the foraging activity of ants, frequently reducing the number and average size of foragers and reducing the amount of food retrieved by a colony.

Controle de Atta laevigata (Hymenoptera: Formicidae) com a isca Landrin-F, em área anteriormente coberta com Eucalyptus Control of Atta laevigata (Hymenoptera: Formicidae), with Landrin-F bait, in areas previously covered with Eucalyptus

Ciência Rural, 1999
Embora muitos produtos tenham sido testados como princípio ativo de iscas formicidas, o mercado predominantemente utilizava produtos à base de dodecacloro. Com a proibição deste último composto, surgiram as iscas à base de sulfluramida ou de clorpirifós,

Seed germination of a myrmecochorous plant endemic to the Brazilian semiarid region: the wolf is not so bad

Acta Botânica Brasílica, 2022
Studies about seed dispersal and germination are important to understand patterns of plant distribution and abundance, and help establish strategies for environmental conservation. We evaluated the role of two different dispersers, the ant Atta laevigata

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

Agricultural 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

Diversity of Fungi Associated with Atta bisphaerica (Hymenoptera: Formicidae): The Activity of Aspergillus ochraceus and Beauveria bassiana

Psyche: A Journal of Entomology, Volume 2012, Issue 1, 2012., 2012
The grass‐cutting ant Atta bisphaerica is one of the most serious pests in several pastures and crops in Brazil. Fungal diseases are a constant threat to these large societies composed of millions of closely related individuals. We investigated the occurrence of filamentous fungi associated with the ant A. bisphaerica in a pasture area of Viçosa, Minas

Influência ambiental na taxa de parasitismo (Diptera: Phoridae) de Atta laevigata e Atta sexdens (Hymenoptera: Formicidae)

Revista de Biologia Neotropical, 2011
Do ponto de vista da sustentabilidade, os sistemas agroecológicos são mais adequados ao controle de pragas do que os sistemas químicos tradicionais, em decorrência da manutenção dos processos ecológicos entre os diversos elementos que compõem a paisagem.

Morphology and Volatilomics of the Pre‐Pharyngeal and Pharyngeal Glands of Paraponera clavata (Hymenoptera: Paraponerinae) and Pachycondyla crassinoda (Hymenoptera: Ponerinae) Workers

Journal of Morphology, Volume 286, Issue 3, March 2025.
This paper describes the morphology and chemical contents of the pre‐pharyngeal and pharyngeal glands in two different ants. The results provide new insights about the morphology and compounds of the exocrine glands in ants. ABSTRACT Ants occur in a remarkable diversity of species, many of which fulfill essential ecological roles and exhibit complex ...
