Growth of populations and the fungus garden of Atta sexdens rubropilosa (Hymenoptera, Formicidae) response to foraged substrates
(2008-11-19)
The leaf-cutting ants forage diverse plants for cultivation of symbiotic fungus, which is a primary food source for larvae in the colony. Previous studies have suggested that continuous offering of a single vegetal species ...
Leaf-cutter ant fungus gardens are biphasic mixed microbial bioreactors that convert plant biomass to polyols with biotechnological applications
(Amer Soc Microbiology, 2015-07-01)
Leaf-cutter ants use plant matter to culture the obligate mutualistic basidiomycete Leucoagaricus gongylophorus. This fungus mediates ant nutrition on plant resources. Furthermore, other microbes living in the fungus garden ...
Fungal communities in gardens of the leafcutter ant Atta cephalotes in forest and cabruca agrosystems of southern Bahia State (Brazil)
(2015-12-01)
Leaf-cutting ants interact with several fungi in addition to the fungal symbiont they cultivate for food. Here, we assessed alien fungal communities in colonies of Atta cephalotes. Fungus garden fragments were sampled from ...
What is the stimulus for the excavation of fungus chamber in leaf-cutting ants?
(Springer, 2015-02-01)
This study investigated the stimulus for the excavation of fungus chamber by leaf-cutting ants (Atta sexdens rubropilosa) during nest building. Thus, it was hypothesized that the fungus garden or the brood is a stimulus ...
Ultrastructural and microbial analyses of cellulose degradation in leaf-cutter ant colonies
(2017)
Leaf-cutter ants (Atta and Acromyrmex) use fresh leaves to cultivate a mutualistic fungus (Leucoagaricus gongylophorus) for food in underground gardens. A new ant queen propagates the cultivar by taking a small fragment ...
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 ...
Growth of populations and the fungus garden of Atta sexdens rubropilosa (Hymenoptera, Formicidae) response to foraged substrates
(California State University, 2014)
Planting of fungus onto hibernating workers of the fungus-growing ant Mycetosoritis clorindae (Attini, Formicidae)
(Birkhauser Verlag Ag, 2010-05-01)
We describe a peculiar fungus-coating behavior of the attine ant Mycetosoritis clorindae, where workers plant fungal mycelium on hibernating nestmates. Hibernating nestmates become ultimately enveloped in a live mycelial ...
