Platzende Arbeiterinnen: Eine neue Art der Feindabwehr bei sozialen Hautflüglern

SummaryWhen disturbed mechanically, minor ofCamponotus (Colobopsis)saundersi and ofC. sp. nearsaundersi contract their gaster until it bursts at an intersegmental fold. The mandibular glands, which extend throughout the whole body, also burst releasing large quantities of a whitish yellow (C. saundersi) resp. bright yellow (C. sp. nearsaundersi) secretion. The secreted fluid is very sticky so that, e.g. attacking ants are unable to move when contaminated. The term “autothysis” (greek.: self… 

Vergleichende Untersuchungen zur Funktion der Ameisenmetathorakaldrüse

It is concluded that the metapleural gland contents function as an antiseptic, with the exception of the gland fluid of Cremastogaster inflata, which was found to suppress the growth of Escherichia coli.

The Chemistry of Exploding Ants, Camponotus SPP. (Cylindricus COMPLEX)

A detailed comparative analysis of the exocrine chemistry of nine Bruneian Camponotus species in the cylindricus complex is reported, finding three species contained (6R)-2,6-dimethyl-(2E)-octen-1,8-dioic acid, previously unreported from insects.

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.

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.

Molecular Mechanism of the Two-Component Suicidal Weapon of Neocapritermes taracua Old Workers.

This work identifies both components of this activated defense system and describes the molecular basis responsible for the toxicity of N. taracua worker autothysis, a sticky and toxic cocktail harmful to opponents.

Comparative morphology of cephalic exocrine glands among castes of the black ant Lasius niger.

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.

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.

Adhesive Exocrine Glands in Insects: Morphology, Ultrastructure, and Adhesive Secretion

A literature survey is provided summarizing the available information on exocrine epidermal glands that produce adhesive secretions in insects. The focus is on both the ultrastructure of the gland



Sting autotomy, a defensive mechanism in certain social Hymenoptera

The acquisition of lancet barbs represents a case of convergent evolution among bees, wasps and ants in the order Hymenoptera and is applied in colony defense and not as an offensive mechanism.
