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 ...

Parabiosis between basal fungus-growing ants (Formicidae, Attini)
Insectes Sociaux, 2008We 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

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.

Dynamic Disease Management inTrachymyrmexFungus-Growing Ants (Attini: Formicidae)
The American Naturalist, 2013Multipartner mutualisms have potentially complex dynamics, with compensatory responses when one partner is lost or relegated to a minor role. Fungus-growing ants (Attini) are mutualistic associates of basidiomycete fungi and antibiotic-producing actinomycete bacteria; the former are attacked by specialized fungi (Escovopsis) and diverse generalist ...

Free-living fungal symbionts (Lepiotaceae) of fungus-growing ants (Attini: Formicidae)
Mycologia, 2009Surveys of leucocoprinaceous fungi (Lepiotaceae, Agaricales, Basidiomycota) in the rainforests of Panama and Brazil revealed several free-living counterparts of fungi cultivated by primitive attine ants (the lower Attini, Formicidae, Hymenoptera), adding to two such collections identified in a survey by Mueller et al (1998).

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 ...

Novel Phialophora species from leaf-cutting ants (tribe Attini)
Fungal Diversity, 2014Ants in the tribe Attini (Hymenoptera, Formicidae) maintain a 50 million-year-old lifestyle of co-evolution with symbiotic basidiomycetous fungi which they cultivate as essential source of nutrition. However, other microorganisms have been reported from ant habitats indicating a higher diversity of consistently associated species than established to ...

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.

Naturwissenschaften, 2005
New World diapriine wasps are abundant and diverse, but the biology of most species is unknown. We provide the first description of the biology of diapriine wasps, Acanthopria spp. and Mimopriella sp., which attack the larvae of Cyphomyrmex fungus-growing ants.
