First Record of the Genus Mycetarotes (Emery, 1913) (Formicidae: Myrmicinae) from Colombia

Sociobiology, 2015
The genus Mycetarotes is a fungus-growing ant (Formicidae: Myrmicinae: Attini) mostly recorded south of the Amazon: in southeastern Brazil, Paraguay, and northern Argentina. Here we report the first record of this genus in Colombia: M. parallelus (Emery,

Symbiont choice in a fungus-growing ant (Attini, Formicidae) [PDF]

Behavioral Ecology, 2004
Cultivars of fungus-growing (attine) ants are vertically transmitted through inheritance from parent to offspring nest, but horizontal cultivar transfer between ant nests occurs occasionally, resulting in cultivar replacement within ant lineages. Two mechanisms could theoretically prevent the invasion of suboptimal cultivar strains and thus stabilize ...

Morphology and histochemistry of the intramandibular glands in Attini and Ponerini (Hymenoptera, Formicidae) species [PDF]

Microscopy Research and Technique, 2010
AbstractAn understanding of the internal morphology of the ant mandible is important in explaining the relationship between the exocrine system and the behavioral and phylogenetic characteristics of different subfamilies of Formicidae. In this study, we investigated the occurrence of intramandibular glands in ants from the Ponerini (Ponerinae) and ...

The Evolution of Tyramides in Male Fungus-Growing Ants (Formicidae: Myrmicinae: Attini: Attina)

Journal of Chemical Ecology, 2022
Abstract Ants use a variety of semiochemicals for essential activities and have been a source for many novel natural products. While ant taxa produce a wide variety of chemicals, the chemistry and ecology of male ants has remained understudied. Tyramides are a class of compound that have been found only in males of the Myrmicinae ant subfamily.

Natural Parasitism in Acromyrmex landolti Forel (Hymenoptera, Formicidae) in Pastures of Bahia, Brazil

Sociobiology, 2015
This study aimed to evaluate the occurrence of natural parasitism in Acromyrmex landolti Forel, identify parasitoids associated to the species and to estimate parasitism rates. The experiment was conducted from January to May 2012 in Itapetinga, BA.

The Metapleural Secretion of Acromyrmex laticeps (Forel) does not have Fungicide Effect on the Entomopathogenic Fungus Beauveria bassiana (Bals.) Vuill

EntomoBrasilis, 2014
The metapleural gland (MPG) is an exocrine structure, exclusive to formicids, being more developed in females and workers. This structure is stunted or nonexistent in males.

Compact Implementation and Performance Evaluation of Hash Functions in ATtiny Devices [PDF]

, 2013
The pervasive diffusion of electronic devices in security and privacy sensitive applications has boosted research in cryptography. In this context, the study of lightweight algorithms has been a very active direction over the last years. In general, symmetric cryptographic primitives are good candidates for low-cost implementations.

Generation of Nutrients and Detoxification: Possible Roles of Yeasts in Leaf-Cutting Ant Nests

Insects, 2012
The possible roles played by yeasts in attine ant nests are mostly unknown. Here we present our investigations on the plant polysaccharide degradation profile of 82 yeasts isolated from fungus gardens of Atta and Acromyrmex species to demonstrate that ...

A Multidisciplinary Approach to Unraveling the Natural Product Biosynthetic Potential of a Streptomyces Strain Collection Isolated from Leaf-Cutting Ants

Microorganisms, 2021
The rapid emergence of bacterial resistance to antibiotics has urged the need to find novel bioactive compounds against resistant microorganisms. For that purpose, different strategies are being followed, one of them being exploring secondary metabolite ...
