At the onset of mating flights inSolenopsis invicta, workers swarm excitedly over the mound as alates prepare to fly. Previous studies demonstrated that this excitement is stimulated by the male and female alates. We investigated the glandular source(s) of pheromones produced by the alates that cause excitement. The only common female and male alate body part that elicited excitement when crushed was the head. Within the head, excised mandibular glands were found to be responsible for worker… 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
Mating Flight Activity as Dealation Factors for Red Imported Fire Ant (Hymenoptera: Formicidae) Female Alates
TLDR
It is suggested that precosene treatment affects the corpora allata (CA), but CA products other than juvenile hormone (JH) or in combination with JH are responsible for rapid dealation after mating. Expand
THE EFFECT OF AGE AND SOCIAL ENVIRONMENT ON DEALATION IN SOLENOPSIS INVICTA (HYMENOPTERA:FORMICIDAE) FEMALE ALATES
TLDR
Investigating whether maturity influences the time at which female alates shed their wings indicated that dealation rates were not different for newly-eclosed (sexually immature) or sexually mature alates, and dealation in the context of the colony and after mating flights appears to occur via separate mechanisms. Expand
Behavioral and Electroantennogram Responses of Phorid fly Pseudacteon tricuspis (Diptera: Phoridae) to Red Imported Fire Ant Solenopsis invicta Odor and Trail Pheromone
TLDR
It is suggested thatFire ant thorax is likely the source of kairomones used as host location cues by P. tricuspis, and the hypothesis that fire ant worker trail pheromones are not likely used by the phorid fly is supported. Expand
Evidence for sex pheromones and inbreeding avoidance in select North American yellowjacket species
TLDR
The absence of sex attraction responses for V. squamosa in this study does not rule out pheromone‐mediated sexual communication, but highlights the possibility that pheromonal signaling may be dependent on the presence of appropriate contextual cues. Expand
The Reproductive Biology of Fire Ant Societies Fire ant females have many and varied reproductive options
T he fire ants are a group of about twenty New World species belonging to the genus and subgenus Solenopsis (Trager 1991). Two species, Solenopsis richteri and Solenopsis invicta, were accidentallyExpand
Isolation of a Pyrazine Alarm Pheromone Component from the Fire Ant, Solenopsis invicta
TLDR
This is the first report of 2-ethyl-3,6-dimethylpyrazine from a Solenopsis species and the first example of this alkaloid functioning as an alarm pheromone. 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
Antennal Olfactory Physiology and Behavior of Males of the Ponerine Ant Harpegnathos saltator
TLDR
Comparing olfactory responses between H. saltator males and females, it is found that sensilla coeloconica and basiconica of workers showed greater responses and broader selectivity to all compounds, which suggests a more specific role in sexual communication compared to that in females, which use CHCs in a broader communication context. Expand
Functional morphology of the mandibular gland of queens of the ant Monomorium pharaonis (L.)
TLDR
It is hypothesized that the glandular secretion serves to stimulate workers to remove the queens’ pupal skin, which suggests that the mandibular gland may indeed play a role in the social facilitation of hatching, although bioassays are required to give decisive answers about the mandIBular gland’s function.

Production and Flight of Alate Red Imported Fire Ants
TLDR
Emergence of alate Solenopsis invicta Buren from several habitats in northern Florida averaged 187,000/acre/year, and first flights composed of alates which developed from the new season's brood occurred in late April and early May. Expand
Phéromones agrégeant les ouvrières de Myrmica rubra
Abstract The workers of Myrmica rubra aggregate around a source of one of their secretions, which can be called ‘alarm pheromone’, and also around workers of Lasius flavus . The mechanism of theseExpand
The inhibitory pheromone of queen fire ants: effects of disinhibition on dealation and oviposition by virgin queens
TLDR
The results demonstrate that the inhibitory pheromone of queen fire ants acts directly on virgin queens and that it prevents muscle histolysis and rapid oogenesis, and the former hypothesis that the phersomone acts mainly on workers and prevents them from causing virgin queens to dealate is disproved. Expand
The behavioral ecology of mating in harvester ants (Hymenoptera: Formicidae: Pogonomyrmex)
TLDR
The combination of distinct daily activity rhythms, partial mating site isolation together with the ability of males to discriminate conspecific females from females of the other species isolates the sympatric Pogonomyrmex species from each other. Expand
Comparative study of the pheromones emitted by workers of the ants Myrmica rubra and Myrmica scabrinodis
TLDR
The volatile components of the Dufour gland secretion are similar in both species and have the short-term effect of encouraging workers to forage, but the less volatile part is quite different in the two species and workers recognize their own from the other species secretion when the volatile components have evaporated away. 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
Multicomponent alarm pheromones of the weaver ant
TLDR
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. Expand
Chemical communication in the dacetine antDaceton armigerum (Hymenoptera: Formicidae)
TLDR
This work identified two anatomical sources of trail pheromones in Daceton armigerum and revealed that the contents of the mandibular glands elicit alarm behavior, and secretions from the pygidial gland release attraction. Expand
Variation with caste of the mandibular gland secretion in the leaf-cutting antAtta sexdens rubropilosa
InAtta sexdens rubropilosa, a strongly polyethic and polymorphic species of myrmicine ant, the contents of the mandibular gland vary with caste. Small workers of head width 0.5–1.8 mm, thoseExpand
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
