Microbial symbionts are shared between ants and their associated beetles
Environmental Microbiology, Volume 25, Issue 12, Page 3466-3483, December 2023., 2023 The colonies of army ants (Formicidae: Dorylinae) are inhabited by hundreds of closely associated insect species (myrmecophiles). Here, we asked about the similarities in microbial community composition between ants and 13 species of myrmecophile beetles.

Rectal enzymes of attine ants. α-Amylase and chitinase [PDF]
Journal of Insect Physiology, 1973 The faecal material of seven species of attine ants from the genera Cyphomyrmex, Apterostigma, Myrmicocrypta, Sericomyrmex, and Atta has been shown to contain c+amylase and chitinase, but only a trace of uricase. Chitinase probably serves a beneficial rBle in the fungus-culturing activities of the primitive form.3 by contributing to the degradation of ...

Three cuticular amides in the tripartite symbiosis of leafcutter ants
Archives of Insect Biochemistry and Physiology, Volume 114, Issue 2, Page 1-13, October 2023., 2023 The heatmap points out three alkyl amides specific for leafcutter ants covered with symbiotic bacteria. These findings indicate an interspecific function of the described compounds within the ant−bacteria relationship. Abstract Cuticular hydrocarbons (CHCs) play various roles in insects' chemical ecology. As leafcutter ants live in a specific symbiosis

Putting the waste out: a proposed mechanism for transmission of the mycoparasite Escovopsis between leafcutter ant colonies [PDF]
Royal Society Open Science, 2017 The attine ant system is a remarkable example of symbiosis. An antagonistic partner within this system is the fungal parasite Escovopsis, a genus specific to the fungal gardens of the Attini.

Ecological Monographs, Volume 93, Issue 1, February 2023., 2023 Abstract Sustaining beneficial gut symbioses presents a major challenge for animals, including holometabolous insects. Social insects may meet such challenges through partner fidelity, aided by behavioral symbiont transfer and transgenerational inheritance through colony founders.

Biological Reviews, Volume 97, Issue 4, Page 1559-1611, August 2022., 2022 ABSTRACT In a much‐cited 1964 paper entitled “Reproductive efficiency in relation to colony size in hymenopterous societies,” Charles Michener investigated the correlation between a colony's size and its reproductive efficiency – the ability of its adult females to produce reproductives, measured as per‐capita output. Based on his analysis of published

Systematic Entomology, Volume 47, Issue 1, Page 13-35, January 2022., 2022 We employ phylogenomic markers (UCEs) to reconstruct the most extensively sampled phylogeny to date for the ecologically dominant leaf‐cutting ant genus Atta, the major herbivore of the New World tropics. The ancestor of Atta arose 8.5 Ma in the North/Central America + NW South America range, and its descendant species rapidly radiated into Neotropical

Metabolism And The Rise Of Fungus Cultivation By Ants [PDF]
, 2014 Most ant colonies are comprised of workers that cooperate to harvest resources and feed developing larvae. Around 50 million years ago (MYA), ants of the attine lineage adopted an alternative strategy, harvesting resources used as compost to produce ...

Ecology and Evolution, Volume 11, Issue 24, Page 17686-17699, December 2021., 2021 In leaf‐cutting ant pests, an obligate mutualistic basidiomycete mediates the ants’ nutrition with carbons from vegetal matter using a fermenter‐like system inside the nest, called a “fungus garden.” Diazotrophs such as Enterobacteriales in the fungus garden and intestinal Rhizobiales were proposed to mediate the incorporation of atmospheric nitrogen ...

The presence of protease activity in the rectal fluid of primitive attine ants. [PDF]
Journal of Insect Physiology, 1971 Abstract The excretion of proteolytic enzymes by representative species of the attine genera Atta, Acromyrmex, Sericomyrmex, Trachymyrmex, Myrmicocrypta, Apterostigma , and Cyphomyrmex has been established. The significance of protease excretion by the primitive attines is discussed in light of their use of materials as substrates in their fungus ...
