ABSTRACT. Major workers of Oecophylla longinoda emit venom from the tip of the abdomen, as it is brought immediately above the head. The sources of the venom are (a) the poison gland, which contains formic acid, and (b) Dufour's gland, which contains hydrocarbons, including n‐undecane and other n‐alkanes, 4‐tridecene, 8‐heptadecene and 4, 7‐heptadecadiene. The venom elicits a ‘mass attack’ response in other major workers. Formic acid and n‐undecane presented together experimentally also evoke… 

Re-Analysis of Abdominal Gland Volatilome Secretions of the African Weaver Ant, Oecophylla longinoda (Hymenoptera: Formicidae)

The chemistry of Dufour’s and poison glands showed a strong overlap and was distinct from that of the rectal and sternal glands, which may contribute to the different physiological and behavioral functions in this ant species.

Multicomponent alarm pheromones in the mandibular glands of major workers of the African weaver ant, Oecophylla longinoda

The mandibular gland secretion of major workers releases in other major workers a complex pattern of behaviour, which includes components of alerting, attraction and biting, and the main constituents are hexanal and 1‐hexanol, which release alerting and attraction respectively.

Overlooked Scents: Chemical Profile of Soma, Volatile Emissions and Trails of the Green Tree Ant, Oecophylla smaragdina

Diverse chemicals from the cuticle, Dufour’s glands, poison glands, head, headspace volatiles, and trails of O. smaragdina are described to enable comparisons in the chemical ecology of the two weaver ant species.

Volatile hydrocarbons in the dufour's gland of the parasiteNemeritis canescens (Grav.) (Hymenoptera; ichneumonidae)

The Dufour's gland of the parasitic waspNemeritis (= Venturia) canescens (Grav.) was shown by gas chromatography and mass spectrometry to contain a mixture of C21, C23, and C25 saturated and

Oviposition responses of Bactrocera dorsalis and Ceratitis cosyra to Dufour’s and poison gland extracts of Oecophylla longinoda (Hymenoptera: Formicidae)

It is suggested that ant gland compounds play a role in the oviposition avoidance behaviour of both African fruit fly species and invasive Asian species, which are repelled by Oecophylla longinoda semiochemicals.

The behaviour and chemistry of recruitment and alarm in social insects

This thesis initially focuses on the chemical ecology of two species of ant; Lasius flavus, the yellow meadow ant and Lasius niger, the common black ant, and the development of a highly sensitive methodology to identify low-concentration pheromones that uses a combination of analytical chemistry and behavioural bioassays.

A masterpiece of evolution – Oecophylla weaver ants (Hymenoptera: Formicidae)

It is speculated that the existence of Oecophylla blocks other weaver ants from evolving highly complex social organization, an idea which could be tested with further knowl-edge on the timing of ant adaptive radiations.

Oviposition responses of Queensland fruit fly (Bactrocera tryoni) to mineral oil deposits on tomato fruit

If the equivalence of no‐choice and choice responses in the laboratory were to hold in the field, then unsprayed ‘sacrificial’ plants would not be necessary and oil emulsions could be used as cover sprays.



Caste and colony variations in the chemical composition of the cephalic secretions of the African weaver ant, Oecophylla longinoda

The quantities of both main and trace constituents of the mandibular gland secretion of major workers were found to vary between colonies collected in different areas of West Africa, suggesting a possible mechanism for communication within the nest.

Multicomponent alarm pheromones of the weaver ant

In the mandibular gland of the African weaver ant Oecophylla longinoda, a detailed study of exocrine secretions that could be implicated in the control of alarm and defence in this ant is initiated.

Similarities between the Dufour Gland Secretions of the Ants Camponotus ligniperda (Latr.) and Camponotus herculeanus (L.) (Hym.)

The present work demonstrates that the two ant species Camponotus ligniperda and herculeanus are very similar also with respect to the composition of the volatile secretions emanating from Dufour's gland in worker ants.

The Evolution of the Alarm-Defense System in the Formicine Ants

It is suggested that two major adaptive alterations in the basic alarm-defense system have occurred within the higher Formicinae and are causally linked to the development of a strongly aggressive form of alarm communication.

Attraction and Alarm of Ants (Camponotus spp.: Hymenoptera: Formicidae) by Pheromones

The initial findings of morphological and chemical investigations on three species of Camponotus are presented with the results of some bioassays with C. pennsylvanicus.

Chemical Communication and "Propaganda" in Slave-Maker Ants

Artificial trails made from whole-body extracts and extracts of Dufour's glands and hindguts can be used to guide columns of workers to selected target colonies and to initiate raids in slave-maker ants of the Formica sanguinea group.

Workers of the African weaver ant Oecophylla longinoda recruit nestmates to previously unoccupied space by means of odor trails laid from the rectal gland, a hitherto unrecognized musculated organ
