Long-term avoidance memory formation is associated with a transient increase in mushroom body synaptic complexes in leaf-cutting ants [PDF]
Frontiers in Behavioral Neuroscience, 2015 Long-term behavioral changes related to learning and experience have been shown to be associated with structural remodeling in the brain. Leaf-cutting ants learn to avoid previously preferred plants after they have proved harmful for their symbiotic ...

Carbon dioxide sensing in an obligate insect-fungus symbiosis: CO2 preferences of leaf-cutting ants to rear their mutualistic fungus. [PDF]
PLoS ONE, 2017 Defense against biotic or abiotic stresses is one of the benefits of living in symbiosis. Leaf-cutting ants, which live in an obligate mutualism with a fungus, attenuate thermal and desiccation stress of their partner through behavioral responses, by ...

FEMS Microbiology Ecology, 2022 Rhizobiales are well-known plant-root nitrogen-fixing symbionts, but the functions of insect-associated Rhizobiales are poorly understood. We obtained genomes of three strains associated with Acromyrmex leaf-cutting ants and show that, in spite of being ...

Morphophysiological differences between the metapleural glands of fungus-growing and non-fungus-growing ants (Hymenoptera, Formicidae). [PDF]
PLoS ONE, 2012 The metapleural gland is an organ exclusive to ants. Its main role is to produce secretions that inhibit the proliferation of different types of pathogens.

Leaf processing behaviour in Atta leafcutter ants: 90% of leaf cutting takes place inside the nest, and ants select pieces that require less cutting [PDF]
Royal Society Open Science, 2016 Leafcutter ants cut trimmings from plants, carry them to their underground nests and cut them into smaller pieces before inoculating them with a fungus that serves as a primary food source for the colony. Cutting is energetically costly, so the amount of

Susceptibility of Atta sexdens worker ants treated with the immunosuppressant Sandimmun Neoral to Metarhizium anisopliae [PDF]
Pesquisa Agropecuária Brasileira, 2017 : The objective of this work was to evaluate if the immunosuppressant Sandimmun Neoral enhances the activity of Metarhizium anisopliae against the leaf-cutting ant Atta sexdens.

Sociobiology, 2023 Leaf-cutting ants manage their waste continuously to avoid risks of colony contamination. The presence of residues or their odor near foraging areas is enough for ants to stop attacking plant tissues.

Adaptive social immunity in leaf-cutting ants [PDF]
Biology Letters, 2009 Social insects have evolved a suite of sophisticated defences against parasites. In addition to the individual physiological immune response, social insects also express ‘social immunity’ consisting of group-level defences and behaviours that include allogrooming.
