Hybienic behavior, liquid-foraging, and trophallaxis in the leafcutting ants, Acromyrmex subterraneus and Acromyrmex [PDF]

Journal of Insect Science, 2009
Neotropical leaf-cutting ants (tribe Attini) live in obligate symbiosis with fungus they culture for food. To protectthemselves and their fungus garden from pathogens, they minimize the entry of microorganisms through mechanicaland chemical means. In this study, focusing on the speciesAcromyrmex subterraneusandA.

Local canopy cover, shade tree identity and landscape tree cover shape leaf‐cutter ant nest density and herbivory in cacao agroforestry systems

Journal of Applied Ecology, Volume 63, Issue 4, April 2026.
Our findings provide practical guidance for agroforestry management by demonstrating that intercropping with selected species can mitigate damage from leaf‐cutter ants in cacao agroforests. At the landscape scale, high tree cover was associated with low herbivory rates, emphasising the need to maintain or restore forested habitats.

DNA Barcode Reference Library for European Ants: A Roadmap for Phylogeography and Species Discovery

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT DNA barcode reference libraries provide useful tools for specimen identification, highlighting potential new species and detecting introduced ones. Here, we present a comprehensive DNA barcode library for European ants and, in order to tackle the Linnean, Wallacean and Darwinian shortfalls of this group, we provide an updated checklist ...

Diversity and Transmission of Gut Bacteria in Atta and Acromyrmex Leaf-Cutting Ants during Development

Frontiers in Microbiology, 2017
The social Hymenoptera have distinct larval and adult stages separated by metamorphosis, which implies striking remodeling of external and internal body structures during the pupal stage.

Towards a Novel Biocontrol Strategy: High Performance of Optimised Cell Wall‐Degrading Enzymes Secreted by Escovopsis primorosea LBM 277

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Escovopsis primorosea LBM 277 efficiently produced proteases, β‐1,3‐glucanases and chitinases under submerged fermentation using Leucoagaricus gongylophorus cell walls and Mandels complex. RSM‐BBD optimization significantly increased enzyme activity. The enzymatic cocktail remained stable for 30 days at room temperature and pH 4–6, aligning with the ...
