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… Expand
Electrophysiological Responses of Eighteen Species of Insects to Fire Ant Alarm Pheromone
TLDR
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. Expand
Multiple functions of fire ant Solenopsis invicta mandibular gland products
TLDR
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. Expand
Fire ant alarm pheromone and venom alkaloids act in concert to attract parasitic phorid flies, Pseudacteon spp.
TLDR
The results suggest an additive rather than a synergistic effect of combining both chemicals, and a host location model is proposed for parasitic phorid flies involving the use of fire ant alarm pheromone and venom alkaloids as long range and short range attractants, respectively. Expand
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 forExpand
Intra- and inter-specific variation in alarm pheromone produced by Solenopsis fire ants
TLDR
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. Expand
Comparative responses of four Pseudacteon phorid fly species to host fire ant alarm pheromone and analogs
TLDR
Comparisons of electroantennogram (EAG) and behavioral responses of four Pseudacteon species confirm that multiple species of phorid flies use fire ant alarm pheromone as a host location cue, but the flies are not strongly attracted to the tested alkylpyrazine analogs of the alarm phersomone. Expand
Pheromone Biosynthesis Activating Neuropeptide (PBAN)/Pyrokinin Family of Peptides and Fire Ants, Solenopsis Spp.
TLDR
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. Expand
Phorid fly, Pseudacteon tricuspis, response to alkylpyrazine analogs of a fire ant, Solenopsis invicta, alarm pheromone.
TLDR
It is proposed that fire ant alarm pheromones may act in tandem or synergistically with venom alkaloids to attract phorid fly parasitoids to fire ant workers. Expand
Age-dependent release of and response to alarm pheromone in a ponerine ant
TLDR
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. Expand
Electrophysiological and Alarm Responses of Solenopsis invicta Buren (Hymenoptera: Formicidae) to 2-Ethyl-3,5-dimethylpyrazine
TLDR
The potential use of 2-ethyl-3,5-dimethylpyrazine to enhance bait attractiveness for the control of S. invicta in invaded regions is supported. Expand

Semiochemicals Released by Electrically Stimulated Red Imported Fire Ants, Solenopsis invicta
TLDR
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. Expand
Fire ant trail pheromones: Analysis of species specificity after gas chromatographic fractionation
TLDR
The specificity of the trail pheromones of four Solenopsis species was determined using natural trails, and purified fractions from Dufour's gland extracts collected after gas-chromatographic separation, to find that S. richteri and S. invicta possess species-specific major trail phersomones. Expand
A Chemical Releaser of Alarm and Digging Behavior in the Ant Pogonomyrmex Badius (Latreille)
TLDR
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. Expand
The alarm-defence system of the ant Acanthomyops claviger
TLDR
The C 10 –C 13 substances are optimal for alarm signalling because, apparently on the basis of molecular weight alone, they combine moderate olfactory efficiency with sufficiently high vapour pressure to broadcast in the centimetre range when present in microgram quantities or less. Expand
Chemical communication among workers of the fire ant Solenopsis saevissima (Fr. Smith) 3. The experimental induction of social responses
TLDR
This work has shown that workers separated from the nest can be induced to orient toward the air removed from around other groups of workers, and indirect evidence has been obtained that one or more simple gaseous excretory products are adequate to produce the response. Expand
Source of alate excitant pheromones in the red imported fire antSolenopsis invicta (Hymenoptera: Formicidae)
TLDR
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. Expand
The alarm-defence system of the ant Lasius alienus
TLDR
Undecane, the principal component, was shown to be more effective as an alarm substance for L. alienus, than for the relazed species Acanthomyops claviger, which appears to depend less in its defence strategy on orientation toward points of disturbances and defensive chemical sprays, and more on ‘early warning’ and evacuation.

Symposium: New Technologies for the Taxonomic Identification of Arthropods: Use of Chemical Characters in Defining Populations of Fire Ants, Solenopsis Saevissima Complex, (Hymenoptera: Formicidae)
TLDR
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
TLDR
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. Expand
Chemical communication among workers of the fire ant Solenopsis saevissima (Fr. Smith) 1. The Organization of Mass-Foraging
TLDR
Recruitment in mass foraging is organized almost exclusively by the use of the trail substance, which is secreted by Dufpur's gland and released through the extruded sting, a powerful attractant which excites workers and draws them out of the nest in the direction indicated by the trail. Expand
