TheSolenopsis invicta trail pheromone is synthesized by the Dufour's gland and is released through the sting apparatus. The recruitment subcategory of theS. invicta trail pheromone was shown to be composed of a mixture of the orientation pheromone, (Z,E)-α-farnesene and an unidentified homosesquiterpene consisting of three rings and one double bond (C-1). C-1 is present in worker Dufour's glands at only 75 pg per worker equivalent. This is the first report that demonstrates that different… 

First identification of a trail pheromone of an army ant (Aenictus species)

The existence of a trail pheromone in a postpygidial gland of an Aenictus species has been demonstrated and the substances identified as methyl anthranilate and methyl nicotinate are identified.

Trail Pheromone of the Argentine Ant, Linepithema humile (Mayr) (Hymenoptera: Formicidae)

The first chemical analyses of the trails laid by living Argentine ants find that (Z)-9-hexadecenal is not present in a detectible quantity and instead, two iridoids, dolichodial and iridomyrmecin, appear to be the primary chemical constituents of the Trails.

Abstract The study of trail laying, recruitment of workers and trail-following by worker ants comprises a co-operative study of entomologists and chemists that has resulted in the identification of

Trail-following responses ofTapinoma simrothi (Formicidae: Dolichoderinae) to pygidial gland extracts

The pygidial (anal) gland was found to be the source of trail pheromone in the antTapinoma simrothi, and the implications of the use of the same glandular secretion for alarm and food recruitments are discussed.

Identification of the Tandem Running Pheromone in Diacamma sp. from Japan (Hymenoptera, Formicidae)

The Japanese queenless ponerine ant Diacamma sp. from Japan employs tandem running during nest relocation, in which a leader ant guides nestmate followers one at a time. We replicated this process by

Insect chemical communication: Pheromones and exocrine glands of ants

This work has described several different types of pheromones of ants, particularly those involved in recruitment, recognition, territorial and alarm behaviours, and identified a wide range of substances from these glands.

Biochemical and behavioral evidence foe hybridization between fire ants,Solenopsis invicta andSolenopsis richteri (Hymenoptera: Formicidae)

The behavioral and biochemical evidence for hybridization was confirmed by gas Chromatograph comparison of the Dufour's gland extracts of the three fire ant forms, which showed a pattern for the hybrid that was intermediate to the two parental species.

Trail Pheromone Disruption of Red Imported Fire Ant

Results show that trailing fire ants become disorientated in the presence of large amounts of Z,E-α-farnesene, and disrupting fire ant recruitment to resources may have a negative effect on colony size or other effects yet to be determined.

Behavioral and Chemical Analysis of Venom Gland Secretion of Queens of the Ant Solenopsis geminata

Gas chromatography coupled mass spectrometry analysis of individual glands of queens of S. geminata showed that the secretion is composed mainly of a large amount of 2-alkyl-6-methylpiperidine alkaloids and a tiny amount of a δ-lactone and a α-pyrone, which have been earlier identified as components of the queen attractant pheromone of Solenopsis invicta Buren.



Piste et phéromone attractive chez la fourmiMyrmica rubra

The worker reaches the nest, meets members of the society and walks back to theLasius, depositing a trail of the attractive secretion of its Dufour's gland, which attracts many ants to the place where help is needed.

Trail pheromone of the red imported fire antSolenopsis invicta (Buren)

Z,Z,Z-Allofarnesene (2Z, 4Z, 6Z)-2,6,10-trimethyl-2, 4, 6, 10-dodecatetraene) was identified as the trail pheromone of the red imported fire ant by comparing chromatographic and spectral properties

The trail pheromone of the ant, lasius fuliginosus: identification of six components.

The trail and alarm pheromones of the ant, Pristomyrmex pungens Mayr

The trail and alarm pheromone of P. pungens was found to be the mixture of 4 monoterpene hydrocarbons (α-pinene, camphene, β- pinene, limonene).

Purification of the Fire Ant Trail Substance

The fire ant, Solenopsis saevissima, utilizes a trail substance from the Dufour's gland which is deposited from the sting in the form of minute streaks to mark a trail from a suitable food source to the nest.

Major hydrocarbons of the post-pharyngeal glands of mated queens of the red imported fire antSolenopsis invicta

Thin layer and column chromatographic analyses showed that hydrocarbons were the major lipoidal components of post-pharyngeal glands of mated queens of the red imported fire ant,Solenopsis invicta, to be identified and confirmed by synthesis and comparative mass spectral analyses.
