A detailed comparative analysis of the exocrine chemistry of nine Bruneian Camponotus species in the cylindricus complex is reported. Workers of these species are known to have hypertrophied mandibular glands and release their glandular contents suicidally from the head by rupturing the inter- segmental membrane of the gaster. All of the species produce mixtures of polyacetate-derived aromatics, including hydroxyacetophenones, which display pH-dependent color changes, and aliphatic hydrocarbons… 

Volatiles from the Mandibular Gland Reservoir Content of Colobopsis explodens Laciny and Zettel, 2018, Worker Ants (Hymenoptera: Formicidae)

It is proposed that the likely irritant and antibiotic phenolic constituents of the MGRC of C. explodens play a role in defense against arthropod opponents or in protection against microbial pathogens.

Colobopsis explodens sp. n., model species for studies on “exploding ants” (Hymenoptera, Formicidae), with biological notes and first illustrations of males of the Colobopsis cylindrica group

This study includes first illustrations and morphometric characterizations of males of the COCY group, known under its vernacular name "exploding ants" for a unique behaviour: during territorial combat, workers of some species sacrifice themselves by rupturing their gaster and releasing sticky and irritant contents of their hypertrophied mandibular gland reservoirs to kill or repel rivals.

Isolation of Mandibular Gland Reservoir Contents from Bornean 'Exploding Ants' (Formicidae) for Volatilome Analysis by GC-MS and MetaboliteDetector

The dissection of worker ants of this species is shown for the isolation of the gastral portion of the wax-like MGR contents as well as listing the necessary steps required for solvent-extraction of the therein contained volatile compounds with subsequent gas chromatography-mass spectrometry (GC-MS) analysis and putative identification of metabolites contained in the extract.

Nutrition of Borneo's ‘exploding’ ants (Hymenoptera: Formicidae: Colobopsis): a preliminary assessment

Functional effects of ants in rainforest canopies depend on difficult to characterize ant diets, and to the extent that COCY workers collect and consume pathogenic and/or beneficial phyllosphere microbes, ant effects on plants may be mediated by these activities.

Antibiotic and Nematocidal Metabolites from Two Lichen Species Collected on the Island of Lampedusa (Sicily)

The results suggest that the substituent pattern at ortho-para-position in respect to both hydroxyl groups of resorcine moiety, which is present in all metabolites, seems very important for nematocidal activity.

Caste-specific morphological modularity in the ant tribe Camponotini (Hymenoptera, Formicidae)

Integrated character complexes in 14 taxa from the genera Camponotus and Colobopsis can be interpreted as functional, caste-specific modules related to behavioural ecology and task allocation within ant colonies.

Histology of structures used in territorial combat by Borneo's 'exploding ants'

Histological studies of the hypertrophied structures of Borneo’s ‘exploding ants’ confirm homology with mandibular glands; reservoirs (only) are hypertrophies as storage structures.

Polyketides in insects: ecological role of these widespread chemicals and evolutionary aspects of their biogenesis

A critical comparison of PKS and FAS architectures and activities supports the hypothesis of a common evolutionary origin of these enzyme complexes and highlights why PKS can catalyse the biosynthesis of much more complex products than can FAS.



The Chemistry of Ants. IV. Terpenoid Constituents of Some Dolichoderus and Iridomyrmex Species

Terpenoid constituents have been isolated from the following Dolichoderus and Iridomyrmex ants. Dolichodial, a novel dicarbonyl compound (C10H14O2), has been extracted from D, acanthoclinea clarki

Chemistry of the mandibular gland secretion of the ant Camponotus vagus

Species-specificity in trail pheromones and Dufour's gland contents ofCamponotus atriceps andC. floridanus (Hymenoptera: Formicidae)

The Dufour's gland contents of both species, investigated by gas chromatographic coupled mass spectrometry, show significant differences.

Trail pheromones and Dufour gland contents in three Camponotus species (C. castaneus, C. balzani, C. sericeiventris: Formicidae, Hymenoptera)

Summary.By means of gas chromatography, gas chromatographic coupled mass spectrometry and behavioral analysis the major trail pheromone components from the hindgut of the formicine species Camponotus

Caste-Specific Compounds in Male Carpenter Ants

Three caste-specific substances new to arthropod glandular secretions occur in the mandibular glands of male ants of five species in the genus Camponotus, which have not been described previously.

Trail pheromone of the antTetramorium impurum and model compounds: Structure-activity comparisons

The major component of the trail pheromone of T. impurum is methyl 2-hydroxy-6-methylbenzoate (methyl 6-methyl salicylate) and the importance of the methyl group and methyl ester were demonstrated, while the hydroxyl group has a relatively small effect.

Trail and recruitment pheromones in Camponotus socius (Hymenoptera: Formicidae)

Workers of Camponotus socius employ multicomponent signals during group recruitment to food sources and nest emigrations that consist of trail orientation pheromones that originate from the hindgut, and two components that elicit trail orientation behavior were identified.
