Influence of Fungal Contamination on Substrate Carrying by the Leafcutter Ant Atta sexdens rubropilosa (Hymenoptera: Formicidae)
(Sociobiology, 2009-01-01) [Artigo]
Toxic baits are the most used method for controlling leafcutter ants and are usually composed of a mixture of dehydrated citric pulp with an active ingredient dissolved in soy oil. In this study, we evaluate if filamentous ...
Yeasts and filamentous fungi carried by the gynes of leaf-cutting ants
(Antonie Van Leeuwenhoek International Journal of General and Molecular Microbiology, 2008-11-01) [Artigo]
Insect-associated microbes exhibit a wide range of interactions with their hosts. One example of such interactions is the insect-driven dispersal of microorganisms, which plays an essential role in the ecology of several ...
Leaf-cutting ant faecal fluid and mandibular gland secretion: effects on microfungi spore germination
(Brazilian Journal of Microbiology, 2008-01-01) [Artigo]
The mandibular gland secretion (MGS) and the faecal fluid (FF) of the leaf-cutting ant Atta sexdens rubropilosa Forel affected the spore germination of selected microfungi isolated from nests of this insect. MGS was more ...
Antagonistic interactions between garden yeasts and microfungal garden pathogens of leaf-cutting ants
(Antonie Van Leeuwenhoek International Journal of General and Molecular Microbiology, 2009-10-01) [Artigo]
We investigate the diversity of yeasts isolated in gardens of the leafcutter ant Atta texana. Repeated sampling of gardens from four nests over a 1-year time period showed that gardens contain a diverse assemblage of yeasts. ...
Comparative analysis of fungal communities in colonies of two leaf-cutting ant species with different substratum preferences
(Fungal Ecology, 2016-06-01) [Artigo]
Fungus gardens of leaf-cutting ants harbor diverse alien fungi in addition to their fungal cultivar. Previous work suggested that alien microorganisms are likely derived from the substrata foraged by ant workers and ...
