1. Comparative morpho-physiology of the metapleural glands of two Atta leaf-cutting ant queens nesting in clayish and organic soils

Author:
Alexsandro Santana Vieira; Maria Izabel Camargo-Mathias; Flavio Roces

Arthropod structure & development 2015 v.44 no.5 pp. 444-454

Subject:
Atta sexdens rubropilosa; antibiotics; antiseptics; evolution; fungus gardens; leaf-cutting ants; microorganisms; nesting; organic matter; organic soils; pathogens; queen insects; risk; soil depth; soil horizons
Abstract:
... Queens of leaf-cutting ants found their nests singly, each consisting of a vertical tunnel and a final horizontal chamber. Because of the claustral mode of nest founding, the queen and/or her initial fungus garden are exposed to threats imposed by several soil pathogens, and the antibiotic secretions produced by their metapleural glands are considered a main adaptation to deal with them. Nests of ...

Abstract:
... Currently, five species are formally described in Escovopsis, a specialized mycoparasitic genus of fungus gardens of attine ants (Hymenoptera: Formicidae: tribe Attini). Four species were isolated from leaf-cutting ants in Brazil, including Escovopsis moelleri and Escovopsis microspora from nests of Acromyrmex subterraneus molestans, Escovopsis weberi from a nest of Atta sp. and Escovopsis lentecr ...

Aspergillus flavus; Atta texana; Fusarium oxysporum; Megaselia scalaris; death; flight; fungi; fungus gardens; social insects; survival rate; Texas
Abstract:
... Nest-founding queens of social insects typically experience high mortality rates. Mortality is particularly severe in leafcutter ants of the fungus-growing ant genus Atta that face the challenge of cultivating a delicate fungus garden in addition to raising brood. We quantified foundress queen survivorship of Atta texana that were collected in northwest Texas and maintained in single-queen laborat ...

Abstract:
... 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 colonies in the Atlantic Rainforest and in a cabruca agrosystem in the state of Bahia (Brazil) in two distinct periods to evaluate whether differences in nest habitat influence ...

Abstract:
... Termitotrox venus sp. n. is described from Cambodia and represents the second discovery of Termitotrox Reichensperger, 1915 from the Indo-Chinese subregion of the Indomalayan region. Most of the type series was collected from refuse dumps in fungus garden cells of Macrotermescf.gilvus (Hagen, 1858). Macrotermes Holmgren, 1910 was previously an unknown host of Termitotrox species. The new species i ...

Abstract:
... Seeds of different plant species constitute an alternative but also significant substrate that leaf-cutting ants use to cultivate their fungus garden. However, how they are processed inside the nest and if their use implies differential allocation of worker size classes are still poorly known. Using laboratory colonies of Acromyrmex subterraneus (Forel) as a model, the behaviors related to the pro ...

Abstract:
... 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 for excavating the chamber. Therefore, four treatments were designed: treatment 1, fixed number of workers (30), without the fungus garden and brood; treatment 2, fixed number of w ...
