A comprehensive biogeographical overview of the evolutionary history of the higher attine ants
Biological Journal of the Linnean SocietyWe investigated the biogeographical history of the higher attines, a group of fungus-farming ants that are widespread across American landscapes. We aimed to determine the tempo and direction of dispersal of their ancestors among the major biomes of ...

A chemical study of the Dufour glands of two attine ants
Insect Biochemistry, 1980Abstract 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 ...

Fungal Cultivars of Higher Attine Ants Promote Escovopsis Chemotropism
Current Microbiology, 2023In varied environments, microorganisms search for partners or nutritional resources using chemical signals. Microbes are drawn (chemotaxis) or grow directionally (chemotropism) towards the chemical source, enabling them to establish and maintain symbiosis.

6. The Symbiosis between the Attine Ants and the Fungi They Culture in Their Nests
Invertebrate-Microbial Interactions, 2020exaly +3 more sources
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 ...

Comparative deterrency of two terpenoids to two genera of attine ants
Journal of Chemical Ecology, 1989Caryophyllene and caryophyllene epoxide are two terpenoids found in neotropical plants and known to be deterrent to leafcutter ants. To estimate the variation in deterrent activity of these compounds toward the generaAtta andAcromyrmex, behavioral bioassays were conducted over a range of concentrations.

Chemical investigations of the Dufour gland contents of Attine ants
Insect Biochemistry, 1981Abstract The Dufour glands of workers of the two subspecies Atta sexdens and Atta sexdens rubropilosa are completely filled with linear alkanes and alkenes in the C15 to C23 chain length range in microgram amounts. There are quantitative differences in the hydrocarbon composition between workers of the two subspecies. The major glandular component of
