From Plants to Ants: Fungal Modification of Leaf Lipids for Nutrition and Communication in the Leaf-Cutter Ant Fungal Garden Ecosystem

mSystems, 2021
Lipids are essential to all living organisms, as an energy source, as an important cellular structural component, and as a communication tool. In this study, we used global lipidomic methods to evaluate the lipids in leaf-cutter ant fungal gardens.

Evaluation of the Toxicity of Virola sebifera Crude Extracts, Fractions and Isolated Compounds on the Nest of Leaf-Cutting Ants

Psyche: A Journal of Entomology, 2012
The phytochemical study of Virola sebifera leaves led to the isolation of three lignans: (+)-sesamin, (−)-hinokinin, and (−)-kusunokinin and three flavonoids: quercetin-3-O-α-L-rhamnoside, quercetin-3-O-β-D-glucoside, and quercetin-3-methoxy-7-O-β-D ...

Chemical analysis and hydroalcoholic extract activity of ferns on the mutualist fungus of leafcutter ants [PDF]

Rodriguésia
Leafcutter ants are among the most important agricultural and forest pests in the Neotropical region, given that they use plant matter as substrate for the growth of their mutualist fungus Leucoagaricus gongylophorus.

Development and validation of a RP-HPLC method to determine the xanthyletin content in biodegradable polymeric nanoparticles

Química Nova, 2014
Xanthyletin is used as an inhibitor of the symbiotic fungus (Leucoagaricus gongylophorus) of the leaf-cutting ant (Atta sexdens rubropilosa), one of the most significant agricultural plague insects.

Selection of leaves of Palicourea padifolia, Platanus mexicana and Eriobotrya japonica by Atta mexicana (Hymenoptera: Formicidae) and its influence on the growth of the mutualistic fungus Leucoagaricus gongylophorus

Botan‪ical Sciences
Background: The foraging preference of Atta mexicana for leaves of three plant species was analyzed under laboratory conditions. Physicochemical characterizations, bioassays with leaf material and crude extracts, and tests on the effect on the ...

Understanding the Hygienic Behavioral Dynamics of Ants Using Multi‐State Models

Entomologia Experimentalis et Applicata, Volume 174, Issue 4, Page 361-370, April 2026.
Leaf‐cutting ants adjust grooming to pathogen risk and vulnerable nestmates. Multi‐state Markov models reveal shorter, frequent self‐grooming bouts and reduced allogrooming persistence under stress, optimizing social immunity via stigmergic decision‐making.

Discussion of development processes in insect‐fungus association derived from the shaggy parasol fruiting on the nests of hairy wood ants

Ecology and Evolution, Volume 9, Issue 20, Page 11619-11630, October 2019., 2019
Chlorophyllum rhacodes, an open forest 'mushroom' species, is occasionally found fruiting on nests of Formica lugubris. Within less mobile thatch of such nests, there was a spatial relationship between C. rhacodes mycelium, insect cadavers, fruitbody initiation, and roots of adjacent trees.
