Parabiosis between basal fungus-growing ants (Formicidae, Attini)
Insectes Sociaux, 2008 We describe the first observation of parabiosis between two Attini ants (Apterostigma urichii Forel and Cyphomyrmex faunulus Wheeler) found in northern Manaus, AM, Brazil. Complete, mature colonies of both species were found in a single cavity inside a rotten log, sharing and tending a single combined fungus garden, made up of two distinct halves, each

Insectes Sociaux, 2011 Some studies require fresh biological material for their development. Ant colonies have been reared under laboratory conditions for scientific purposes, and several methodologies for leafcutter ants have been reported in the literature.

Alarm pheromones of the Attini: Their phylogenetic significance
Journal of Insect Physiology, 1972Abstract The volatile components present in the mandibular glands of a number of species of the attine genera Cyphomyrmex (1 species), Trachymyrmex (3 species), and Acromyrmex (2 species) were investigated and compared with those present in Atta. The extracts were found to consist of mixtures of a number of compounds.

Orientation in leaf-cutting ants (Formicidae: Attini)
Animal Behaviour, 1987Abstract The cues used for orientation on chemical trails by laboratory colonies of Atta cephalotes, Atta laevigata and Acromyrmex octospinosus were studied. The ants used cues other than the odour trail itself when homing. When cues gave contradictory information, Atta workers used them in a certain hierarchy: presence of an odour trail ...

Feasibility of PUF-Based Authentication on ATtiny Devices with Off-the-Shelf SRAM
Proceedings of the 6th ACM on Cyber-Physical System Security Workshop, 2020With the proliferation of connected IoT devices over the last decade, security has become one of the most pronounced areas of technical concern. Furthermore, the most important challenge being device authentication and trust management of resource constrained IoT devices.

Phylogeny of Fungus-Growing Ants (Tribe Attini) Based on mtDNA Sequence and Morphology
Molecular Phylogenetics and Evolution, 1998We examined the phylogenetic relationships among taxa of attine or "fungus-growing" ants (Tribe Attini) using parsimony analyses of molecular and morphological data. We sequenced a region of mitochondrial DNA from 13 taxa of attines and from one closely related outgroup species, Wasmannia auropunctata.

Nesting biology of the fungus growing ants Mycetarotes Emery (Attini, Formicidae)
Insectes Sociaux, 2004Fungus-growing ants of the genus Mycetarotes are among the least studied in the tribe Attini. This report documents nest architecture and worker population numbers for 19 nests of M. parallelus and 5 nests of M. acutus, including the first such report for M. acutus.

Using Arduino with PIC32 and ATtiny Atmel Chips
2013Transitioning from standard to custom Arduino hardware can save space and money. Custom boards can add new capabilities to projects through increased speed, memory, and pins, as well as new features. This chapter will look at chips and boards on a spectrum from the power and complexity of the Leonardo to the inexpensive simplicity of the ATtiny.

Reserves in sexual forms ofAcromyrmex octospinosus (Reich) (Formicidæ, Attini)
Insectes Sociaux, 19791 - Sexual brood and adults were taken from laboratory colonies ofAcromyrmex octospinosus (Reich) for observation and analysis. 2 - The reproductive castes were much larger than the workers. 3 - A sex difference in lipid metabolism was found between the reproductive castes, adult gynes possessing seven times the amount of ...
