In 6 of 7 ant subfamilies investigated, the workers produce an acidic secretion in their metapleural glands. With the exception of the gland fluid of Cremastogaster (Physocrema) inflata, all tested secretions were found to suppress the growth of Escherichia coli. From this and from former results, it is concluded that the metapleural gland contents function as an antiseptic.In Cremastogaster inflata the metapleural gland is greatly enlarged. The workers release the highly sticky secretion when… Expand

A synthetic approach integrating functional morphology, phylogenetic transitions and chemical ecology of the MGs of both the derived and the unstudied early‐branching (basal) ant lineages is needed to elucidate the evolutionary origin and diversification of the MG of ants. Expand
Secretory profile of metapleural gland cells of the leaf‐cutting ant Acromyrmex coronatus (Formicidae: Attini)
The findings revealed that the secretory and the storage portions of this gland are connected by extracytoplasmic portion of canaliculi that drain the secretion from each secretory cell to the collecting chamber, supporting the role of the metapleural gland in the maintenance of the fungus garden.

Chemical composition and function of metapleural gland secretion of the ant,Crematogaster deformis smith (hymenoptera: Myrmicinae)
The secretion of the hypertrophied metapleural gland of the antCrematogaster deformis contains a mixture of phenols, consisting mainly of 3,4-dihydro-8-hydroxy-3-methylisocoumarin (mellein), 5-propylresorcinol, and 5-pentylresol, which has some insecticidal properties. Expand
Chemical Composition of Metapleural Gland Secretions of Fungus-Growing and Non-fungus-growing Ants
The results showed that the secretions of leaf-cutting ants and the derived attine, T. fuscus, contain a greater variety and larger quantities of volatile compounds than those of myrmicine and ectatommine ants. Expand
Metapleural Gland Secretion of the Leaf-cutter Ant Acromyrmex octospinosus: New Compounds and Their Functional Significance
A comprehensive analysis of metapleural gland secretions of Acromyrmex octospinosus using a recently developed method for the analysis of polar compounds by gas chromatography and mass spectrometry shows that the chemical identity and quantitative recovery of different compounds in the metapeural gland secretion depends upon the method used and the type of colony from which the samples are taken.

The functional morphology of the metapleural gland of the leaf-cutting ant Atta laevigata (Formicidae: Attini).
Morphometrically, the diameter of the reservoir is proportional to body size of minor, media, and major workers, which implies a larger capacity to produce secretion, including antibiotic substances, by the individuals that perform specific tasks within the colony. Expand
Defensive behaviour and biological activities of the abdominal secretion in the ant Crematogaster scutellaris (Hymenoptera: Myrmicinae)
The main biological activity of the abdominal secretion of C. scutellaris seems to be its repellency to other ant species, supported by field experiments showing that Pheidole pallidula foragers were efficiently repelled at coexploited baits, allowing the monopolization of most prey by C. SCUTellaris. Expand
Regulation and specificity of antifungal metapleural gland secretion in leaf-cutting ants
The MG defence system of leaf-cutting ants has characteristics reminiscent of an additional cuticular immune system, with specific and non-specific components, of which some are constitutive and others induced. Expand
Oily substances from gastral intersegmental glands of the antPachycondyla tridenta (Ponerinae): Lack of pheromone function in tandem running and antibiotic effects but further evidence for lubricative function
Morphology and position of the glands, lack of pheromonal function, oily properties, low volatility, and lack of antibiotic effects of these secretions strongly suggest a function as lubricants for the ants' gastral segments. Expand

An Hypothesis Concerning the Function of the Metapleural Glands in Ants

  • 1968
A rapid survey of the collection of the ants in the Museum of Comparative Zoology, Harvard University, and some other collections, has turned up additional cases of ants in which, judging now only from externally visible structures, the metapleural gland is absent, nonfunctional, or significantly reduced.

Ein Beitrag zur Funktion der Metathoracaldruse der Ameisen
The metapleural glands serve as a source of antiseptic; they protect the body surface and the nest against micro-organisms in the species of ants investigated. Expand

This completes the important section of Aculeata, or stinging Hymenoptera, and the monographing of the remaining groups, which are still very imperfectly known, is very properly deferred for the present. Expand
