A chemical study of the Dufour glands of two attine ants.

Insect Biochemistry, 1980
Abstract The Dufour glands of Atta Cephalotes and Acryomyrmex octospinosus are similar in appearance to those of other myrmicine ants but essentially contain no volatile chemicals. That of A. cephalotes contains a few ng of linear hydrocarbons, with n- heptadecane being the major product but these represent about 4% of the volume of the ...

Symbiont recruitment versus ant-symbiont co-evolution in the attine ant–microbe symbiosis

Current Opinion in Microbiology, 2012
The symbiosis between fungus-farming ants (Attini, Formicidae), their cultivated fungi, garden-infecting Escovopsis pathogens, and Pseudonocardia bacteria on the ant integument has been popularized as an example of ant-Escovopsis-Pseudonocardia co-evolution.

The evolution of thermal performance curves in fungi farmed by attine ant mutualists in aboveground or belowground microclimates.

Journal of Evolutionary Biology
Fungi are abundant and ecologically important at a global scale, but little is known about whether their thermal adaptations are shaped by biochemical constraints (i.e.

Ant versus Fungus versus Mutualism: Ant‐Cultivar Conflict and the Deconstruction of the Attine Ant‐Fungus Symbiosis

The American Naturalist, 2002
A century of research on fungus-growing ants (Attini, Formicidae) has ignored the cultivated fungi as passive domesticates and viewed the attine fungicultural symbiosis as an integrated unit dominated by the evolutionary interests of the ant farmers. This article takes a different perspective and explores first the evolutionary interests and leverages ...

The Adaptiveness of Worker Demography in the Attine Ant Trachymyrmex Septentrionalis

Ecology, 1994
Castle theory states that worker size distributions in ant colonies have evolved for efficient division of labor and predicts that they should vary with habitat and have an effect on fitness. We tested these predictions in a comparative study of worker size variation and colony fitness in Florida and Long Island populations of Trachymyrmex ...

The Chemical Basis for the Attine Ant-Fungus Symbiosis. Absence of Antibiotics

Annals of the Entomological Society of America, 1969
The theory that attine ants maintain pure cultures of their food fungi by application of antibiotics to their fungus gardens has been rendered untenable. Extracts prepared from the ant Atta colombica tonsipes Santschi, from its wild fungus gardens, from expended fungus gardens, and from laboratory cultures of its fungus have been assayed for antibiotic
