In vitro study of volatile organic compounds produced by the mutualistic fungus of leaf-cutter ants and the antagonist Escovopsis
(2020-12-01)
Occasionally, the symbiosis of the fungus-growing ants is threatened by ascomycetous fungi mainly by species in the genus Escovopsis. GC-MS analyses were conducted to investigate the volatile organic compounds (VOCs) ...
Broad Escovopsis-inhibition activity of Pseudonocardia associated with Trachymyrmex ants
(Wiley-Blackwell, 2014-08-01)
Attine ants maintain an association with antibiotic-producing Actinobacteria found on their integuments. Evidence supports these bacteria as auxiliary symbionts that help ants to defend the fungus gardens against pathogens. ...
Escovopsis trichodermoides sp nov., isolated from a nest of the lower attine ant Mycocepurus goeldii
(Springer, 2015-03-01)
Currently, five species are formally described in Escovopsis, a specialized mycoparasitic genus of fungus gardens of attine ants (Hymenoptera: Formicidae: tribe Attini). Four species were isolated from leaf-cutting ants ...
New light on the systematics of fungi associated with attine ant gardens and the description of escovopsis kreiselii sp nov
(Public Library Science, 2015-01-24)
Since the formal description of fungi in the genus Escovopsis in 1990, only a few studies have focused on the systematics of this group. For more than two decades, only two Escovopsis species were described; however, in ...
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, ...
Fungi inhabiting attine ant colonies: reassessment of the genus Escovopsis and description of Luteomyces and Sympodiorosea gens. nov.
(2021-12-01)
Escovopsis is a diverse group of fungi, which are considered specialized parasites of the fungal cultivars of fungus-growing ants. The lack of a suitable taxonomic framework and phylogenetic inconsistencies have long ...
Host Susceptibility Modulates Escovopsis Pathogenic Potential in the Fungiculture of Higher Attine Ants
(2021-06-14)
Health and disease emerge from intricate interactions between genotypes, phenotypes, and environmental features. The outcomes of such interactions are context-dependent, existing as a dynamic continuum ranging from benefits ...
Shared Escovopsis parasites between leaf-cutting and non-leaf-cutting ants in the higher attine fungus-growing ant symbiosis
(2015)
Fungus-gardening (attine) ants grow fungus for food in protected gardens, which contain beneficial, auxiliary microbes, but also microbes harmful to gardens. Among these potentially pathogenic microorganisms, the most ...
Lack of fungal cultivar fidelity and low virulence of Escovopsis trichodermoides
(2020-06-01)
Fungus-growing ants (the attines) are a paramount example of symbiosis, practicing fungiculture for food. Fungi in the genus Escovopsis (Ascomycota: Hypocreales) threaten the ant fungal cultivars and show patterns of ...
Absence of the Parasite Escovopsis in Fungus Garden Pellets Carried by Gynes of Atta sexdens
(Univ Estadual Feira Santana, 2015-03-01)
Before the mating flight, the gyne of leaf-cutting ants takes a small pellet of their mutualistic fungus garden to start fungus culture in its new colony by vertically transmitting it. This mutualism is threatened by the ...
