Reconstructing the functions of endosymbiotic Mollicutes in fungus-growing ants

eLife, 2018
Mollicutes, a widespread class of bacteria associated with animals and plants, were recently identified as abundant abdominal endosymbionts in healthy workers of attine fungus-farming leaf-cutting ants.

Mandibular and postpharyngeal gland secretions of Acromyrmex landolti (Hymenoptera: Formicidae) as chemical cues for nestmate recognition

Revista de Biología Tropical, 2013
Nestmate recognition is fundamental for the cohesiveness of the colony in social insects. Acromyrmex landolti is a higher Attini, a leaf-cutter ant with largest nest and morphological castes.

Morphological and morphometric studies of the antennal sensilla from two populations of Atta robusta (Borgmeier 1939) (Hymenoptera: Formicidae)

Brazilian Journal of Biology
The ant Atta robusta is endemic to the “restinga” ecosystems where it has an important role in the dynamics of seed dispersal. Despite its importance, A. robusta is considered a threatened species. In this study we analyzed the antennal sensory organs of

Lipid Mobilization and Acyl-Coenzyme A Dehydrogenase Abundance in the Postpharyngeal Gland of a Leaf-Cutting Ant

Sociobiology, 2016
The postpharyngeal gland (PPG) in ants has a central role in lipid accumulation. Our objective was to investigate whether the PPG of workers of the leaf-cutting ant Atta sexdens rubropilosa (F.) performs lipid mobilization to the hemolymph, and to verify

Black fungi on the integument of leaf-cutting ants (Tribe Attini)

, 2016
As relações das formigas da tribo Attini com seu fungo mutualista e outros micro-organismos são estudadas há mais de 120 anos, porém o vínculo com fungos negros foi recentemente descoberto e até o momento pouco explorado.

Response of the grass-cutting ant Atta capiguara Gonçalves, 1944 (Hymenoptera: Formicidae) to sugars and artificial sweeteners

Scientia Agricola, 2003
Using of toxic baits made of dehydrated citric pulp to control grass-cutting ants can lead to unsatisfactory results because of the low attractiveness of the substrate to worker ants.
