DOI: 10.1007/s10482-021-01555-1
Abstract: The leaf-cutter ant Acromyrmex balzani is responsible for causing important losses in reforestation areas, crops, and pastures, and is frequently found in the Brazilian savanna (Cerrado). So far, there is no information regarding the yeast… read more here.

DOI: 10.1038/s41467-020-19566-3
Abstract: Although calcareous anatomical structures have evolved in diverse animal groups, such structures have been unknown in insects. Here, we report the discovery of high-magnesium calcite [CaMg(CO3)2] armor overlaying the exoskeletons of major workers of the… read more here.

DOI: 10.1080/09583157.2018.1479730
Abstract: ABSTRACT Leaf cutter ants are one of the most important pests to agriculture and forestry in the Neotropics. One environmentally friendly solution to control them is biological control with the use of conidia of some… read more here.

DOI: 10.1080/17513758.2022.2099590
Abstract: In this paper, we propose a stochastic delay mutualistic model of leaf-cutter ants with stage structure and their fungus garden, in which we explore how the discrete delay and white noise affect the dynamic of… read more here.

DOI: 10.1093/aobpla/plx057
Abstract: Leaf-cutter ants are the most important pest insect in agriculture. Their association with Ocimum species is common in Brazil. O. gratissimum presents three morphotypes of glandular trichomes producing compounds with anti-herbivore properties. Under an experimental… read more here.

DOI: 10.1093/ee/nvx162
Abstract: Abstract Ecosystem engineers are profoundly important in many biological communities. A Neotropical taxonomic group considered to have engineering effects is the Formicidae (ants). Leaf-cutter ants (LCAs), in particular, which form extensive colonies of millions of… read more here.

DOI: 10.1128/mbio.01885-21
Abstract: In some plants and animals, beneficial microbes mediate host immune response against pathogens, including by serving as defensive symbionts that produce antimicrobial compounds. Defensive symbionts are known in several insects, including some leaf-cutter ants where… read more here.

DOI: 10.1128/msystems.01307-20
Abstract: In this work, we examined the role of lipids in the mutualism between leaf-cutter ants and fungus. These ants cut fresh leaf material, which they provide to their fungal cultivar, that converts energy and nutrients… read more here.
