More pieces to a huge puzzle: Two new Escovopsis species from fungus gardens of attine ants
(2019-02-18)
Escovopsis (Ascomycota: Hypocreales, Hypocreaceae) is the only known parasite of the mutualistic fungi cultivated by fungus-growing ants (Formicidae: Myrmicinae: Attini: Attina, the “attines”). Despite its ecological role, ...
Coping with temperature extremes: thermal tolerance and behavioral plasticity in desert leaf-cutting ants (Hymeno ptera: Formicidae) across an altitudinal gradient
(Oesterreichische Gesell Entomofaunistik, 2020-06-10)
Current approaches to assess and predict the impact of climate warming on ectotherms are largely based on their physiological sensitivity to temperature. However, these physiological studies provide little insight into the ...
Sex allocation in the polydomous leaf-cutting ant Acromyrmex balzani
(Springer, 2007-03-01)
Logistic regression analysis was used to analyse sex allocation in a population of the leaf-cutting ant Acromyrmex balzani occurring in a pasture in southern Brazil. The field sample consisted of 151 fungus-garden chambers ...

Survival of Atta sexdens workers on different food sources
(Elsevier B.V., 2003-04-01)
Leaf-cutting ants belonging to the tribe Attini are major herbivores and important agriculture pests in the neotropics, these ants being thought to feed on the sap which exudes from the plant material which they cut and ...

Interação patógeno-hospedeiro na fungicultura das formigas atíneas derivadas
(Universidade Estadual Paulista (Unesp), 2017-03-31)
A fungicultura das formigas atíneas é um modelo atrativo para estudar associações parasita-hospedeiro, pois abriga um amplo número de parasitas e hospedeiros filogeneticamente diversos. As formigas atíneas dependem do ...
A Brazilian population of the asexual fungus-growing ant Mycocepurus smithii (Formicidae, Myrmicinae, Attini) cultivates fungal symbionts with gongylidia-like structures
(Public Library Science, 2014-08-07)
Attine ants cultivate fungi as their most important food source and in turn the fungus is nourished, protected against harmful microorganisms, and dispersed by the ants. This symbiosis evolved approximately 50-60 million ...
Assessment of microfungi in fungus gardens free of the leaf-cutting ant Atta sexdens rubropilosa (Hymenoptera: Formicidae)
(2005-10-05)
The purpose of this study was to determine the microfungi present in young nests of Atta sexdens rubropilosa when the fungus gardens were deprived of worker ants. The results were compared with another study in which worker ...
