Alarm pheromones in social insects are an essential part of a complex of pheromone interactions that contribute to the maintenance of colony integrity and sociality. The alarm pheromones of ants were among the first examples of animal pheromones identified, primarily because of the large amount of chemical produced and the distinctive responses of ants to the pheromone. However, the alarm pheromone of the fire ant, Solenopsis invicta, eluded identification for over four decades. We identified 2… 

Electrophysiological Responses of Eighteen Species of Insects to Fire Ant Alarm Pheromone

Electroantennography responses to EDP indicate that EDP can be detected by widespread insect species that did not coevolve with S. invicta and alkylpyrazine may activate multiple generally tuned olfactory receptors (ORs) across a wide number of insect species.

Multiple functions of fire ant Solenopsis invicta mandibular gland products

The results of the present study indicate that male and female sexuals use mandibular gland secretions for mating flight initiation and during mating flights, suggesting new roles for mandIBular gland products in fire ants.

Electroantennogram and behavioral responses of the imported fire ant, Solenopsis invicta Buren, to an alarm pheromone component and its analogues.

A characteristic behavior in ants is to move rapidly to emission sources of alarm pheromones. The addition of ant alarm pheromones to bait is expected to enhance its attractiveness. To search for

Intra- and inter-specific variation in alarm pheromone produced by Solenopsis fire ants

It seems likely that higher alarm pheromone content may have favored invasion success of exotic fire ants over native species, and the potential role of inter-specific variation in pyrazine content for the relationship between the observed shifts in the spatial distributions of the three exotic fire ant species in southern United States and the displacement of nativeFire ant species.

Pheromone Biosynthesis Activating Neuropeptide (PBAN)/Pyrokinin Family of Peptides and Fire Ants, Solenopsis Spp.

Research to date on the PBAN/pyrokinin gene and the fire ant is reviewed in preparation for determining the function of the product neuropeptides in brood development and in adults, to lay the ground-work for the utilization of thePBAN/PyrokinIn gene/peptide product system for novel biologically-based fire ant control.

Age-dependent release of and response to alarm pheromone in a ponerine ant

Worker castes in a monomorphic ponerine ant differ in their propensity to emit a chemical alarm signal as well as in their behavioural reaction towards it.

Electrophysiological and Alarm Responses of Solenopsis invicta Buren (Hymenoptera: Formicidae) to 2-Ethyl-3,5-dimethylpyrazine

The potential use of 2-ethyl-3,5-dimethylpyrazine to enhance bait attractiveness for the control of S. invicta in invaded regions is supported.



Semiochemicals Released by Electrically Stimulated Red Imported Fire Ants, Solenopsis invicta

The behaviors associated with these products support the hypothesis that the accumulation of fire ants in electrical equipment is the result of a foraging worker finding and closing electrical contacts, then releasing exocrine gland products that attract other workers to the site, who in turn are electrically stimulated.

A Chemical Releaser of Alarm and Digging Behavior in the Ant Pogonomyrmex Badius (Latreille)

According to this author, workers of certain deserticolous species of the dolichoderine and formicine genera ForeIius, Tapinornu, Iridomynflex, Doryrnyrnex, and Camponotvs apparently can discharge abdominal secretions that create this effect among other workers through the air over short distances.

Source of alate excitant pheromones in the red imported fire antSolenopsis invicta (Hymenoptera: Formicidae)

The glandular source(s) of pheromones produced by the alates that cause excitement in Solenopsis invicta are investigated and it is concluded that the mandibular gland is the source of alate excitant peromones.

Symposium: New Technologies for the Taxonomic Identification of Arthropods: Use of Chemical Characters in Defining Populations of Fire Ants, Solenopsis Saevissima Complex, (Hymenoptera: Formicidae)

The use of three species-specific chemical characters (venom alkaloids, cuticular hydrocarbons, and trail pheromones) to define S. invicta, S. richteri, and hybrid populations in the United States have important consequences regarding the species status of the two imported fire ants and the taxonomy of fire ant populations in South America.

Gaster flagging by fire ants (Solenopsis spp.): Functional significance of venom dispersal behavior

Observations suggest that airborne venom dispersal by workers is context specific rather than temporal caste specific and that workers can control the quantity of venom released.

Comparative Study of Mandibular Gland Secretions of Workers of Ponerine Ants

All the 33 known mandibular gland analyses of workers of ponerine ant species have been brought together in order to seek some pattern in the type of glandular contents, finding no observable pattern on a tribe or genus level.
