Allogrooming, self-grooming, and touching behavior: Contamination routes of leaf-cutting ant workers using a fat-soluble tracer dye
(Insects, 2017-06-09) [Artigo]
The aim of this study was to determine whether worker self-grooming, allogrooming, and direct contact promotes the dispersal of substances among members of the colony. For this purpose, a tracer (Sudan III dye) was applied ...
Discovering the giant nest architecture of grass-cutting ants, Atta capiguara (Hymenoptera, Formicidae)
(Insects, 2017-06-01) [Artigo]
Atta capiguara is a grass-cutting ant species frequently found in Cerrado biome. However, little is known about the giant nest architecture of this ant. In this study, we investigated the architecture of three A. capiguara ...
Behavioral Response of the Leafcutter Ant, Atta sexdens rubropilosa (Hymenoptera, Formicidae), to Components of Citrus Pulp
(Sociobiology, 2010-01-01) [Artigo]
Citrus pulp is an attractive substrate for dicotyledon-cutting ants, due to its physical and chemical properties. In this study, the behavioral response of Atta sexdens rubropilosa workers to different components of the ...
Microscopic evidence supports the hypothesis of high cellulose degradation capacity by the symbiotic fungus of leaf-cutting ants
(Journal of Biological Research-thessaloniki, 2011-01-01) [Artigo]
Leaf-cutting ants (Hymenoptera, Formicidae) use fresh leaf fragments to cultivate a symbiotic fungus (Basidiomycota, Agaricales) as their food source. There are three hypothetical propositions for the degree of cellulose ...
Relationship between mandible morphology and leaf preference in leaf-cutting ants (Hymenoptera: Formicidae)
(Revista Colombiana De Entomologia, 2015-07-01) [Artigo]
Morphological differences among mandibles of grass and leaf-cutting ant species were examined. Specifically, we compared morphometric measurements from mandibles of four species (Atta laevigata, A. bisphaerica, Acromyrmex ...
