    Pheromonal control of dealation and oogenesis in virgin queen fire ants (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-04-03
    Description: In the fire ant Solenopsis invicta, sexually mature virgin females are prevented from shedding their wings and becoming functional egg layers by the presence of the mated queen. Experimental data suggest that this inhibitory effect results from the action of a relatively nonvolatile primer pheromone (or pheromones) produced by the mated queen and distributed by the workers. Target ants are both virgin queens and workers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fletcher, D J -- Blum, M S -- New York, N.Y. -- Science. 1981 Apr 3;212(4490):73-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17747633" target="_blank"〉PubMed〈/a〉

    Defense in thrips: forbidding fruitiness of a lactone (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-04-15
    Description: Expulsion of anal fluid from the upturned abdomen was demonstrated to serve a defensive function in the thrips Bagnalliella yuccae. An allomone in the anal exudate was identified as gamma-decalactone, a fruity-smelling compound that repelled potential predators. Chemical defenses may contribute to the ability of thrips to maintain large aggregations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Howard, D F -- Blum, M S -- Fales, H M -- New York, N.Y. -- Science. 1983 Apr 15;220(4594):335-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17732921" target="_blank"〉PubMed〈/a〉

    Proteins in a nonvenomous defensive secretion: biosynthetic significance (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-08-04
    Description: In common with many arthropods, the true bug, Leptoglossus phyllopus, when disturbed, emits a two-phase secretion that consists of an organic phase and an aqueous phase. The organic phase is a mixture of highly reactive low-molecular-weight compounds, analogous to those produced by other arthropods, and is deterrent to many kinds of predators. The aqueous phase, heretofore ignored in most analyses of arthropod defensive secretions, contains proteins. Even though the secretion is not injected, the proteins enzymatically catalyze the derivation of the most reactive components within the impermeable cuticular storage reservoir and, thus, constitute part of the defensive system that appears to be commonly used by arthropods producing irritating chemicals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aldrich, J R -- Blum, M S -- Hefetz, A -- Fales, H M -- Lloyd, H A -- Roller, P -- New York, N.Y. -- Science. 1978 Aug 4;201(4354):452-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17729900" target="_blank"〉PubMed〈/a〉

    Biosynthesis and Accumulation of Formic Acid in the Poison Gland of the Carpenter Ant Camponotus pennsylvanicus (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-08-04
    Description: Formic acid synthesis in the poison gland of Camponotus pennsylvanicus is closely related to the C-1 metabolism of the glandular cells. Serine, glycine, and histidine are potential C-l donors to formic acid by several tetrahydrofolate intermediates. Formic acid is accumulated by its transfer to an insulated reservoir, so that the ant avoids the acid's cytotoxicity. This combination of biochemical and morphological features provides an autodefensive mechanism. Possible factors that regulate the biosynthesis of formic acid in the poison gland apparatus are discussed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hefetz, A -- Blum, M S -- New York, N.Y. -- Science. 1978 Aug 4;201(4354):454-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17729901" target="_blank"〉PubMed〈/a〉

    Regulation of queen number by workers in colonies of social insects (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-01-21
    Description: Experiments with fire ants suggest that queen pheromones act quantitatively in the regulation of queen number in colonies of social insects. Specific mechanisms probably include recognition by workers of unique quantitative blends of pheromones produced by queens, and quantitative effects of pheromones acting at the level of the colony on workers and at the level of the individual on queens. Several aspects of this quantitative hypothesis of pheromone action were tested.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fletcher, D J -- Blum, M S -- New York, N.Y. -- Science. 1983 Jan 21;219(4582):312-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17798282" target="_blank"〉PubMed〈/a〉

    A harvester ant venom: chemistry and pharmacology (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-06-02
    Description: The mammalian toxicity of the potently algogenic venom of the ant Pogonomyrmex badius is greater than that reported for any other insect venom. This enzyme-rich venom contains high concentrations of phospholipase A2 and B, hyaluronidase, acid phosphatase, lipase, and esterases. This hemolytic secretion from the poison gland products unusual symptoms in mammals and appears to have been evolved as a deterrent for vertebrate predators.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schmidt, J O -- Blum, M S -- New York, N.Y. -- Science. 1978 Jun 2;200(4345):1064-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/653354" target="_blank"〉PubMed〈/a〉

Während einer aggressiven interspezifischen Begegnung kann die kleine Ameise das Alkylpyrazin als ein Abstossungsmittel benutzen und ihren Opponenten noch dazu mit ihrem wirkungsvollen giftigen Stich untauglich machen. Alkylpyrazine sind schon früher in Vertreten der Unterfamilien Ponerinæ, Formicinæ und Dolichoderinæ gefunden worden, jedoch ist dies der erste Bericht über Alkylpyrazine in den mandibularen Drüsen einer Art der Myrmicinæ.
    Notes: Summary Mandibular glands of the ant,Wasmannia auropunctata, contain 2,5-dimethyl-3-isopentylpyrazine, a compound which attracts nestmates to disturbed workers. During interspecific aggressive encounters, this small ant may utilize the alkylpyrazine as a repellent as well as disabling opponents with its potent sting venom. Alkylpyrazines have been previously identified as cephalic products from ants of the subfamilies Ponerinæ, Formicinæ, and Dolichoderinæ but this is the first report of an alkylpyrazine from the mandibular glands of a member of the Myrmicinæ.

    Description / Table of Contents: Resume Lorsque des reines vierges de la fourmi de feu sont soustraites à l'influence de la phéromone inhibitrice produite par la reine, elles perdent leurs ailes plus facilement en présence d'ouvrières qu'en leur absence. Lorsqu'elles sont isolées pendant 72 heures après la levée de l'inhibition, un nombre significativement plus grand de reines vierges ayant hiverné perdent leurs ailes, par rapport aux reines vierges élevées au printemps. Toutefois, les nombres d'individus perdant leurs ailes en présence d'ouvrières sont similaires. Après désinhibition, quelques reines vierges immatures perdent leurs ailes. Les sexués vierges désailés sont capables de prévenir la perte des ailes chez d'autres sexués vierges. Les divers facteurs influençant la déalation chez les reines vierges ont été utilisés afin de développer un essai biologique pour la phéromone inhibitrice produite par la reine deS. invicta.
    Notes: Summary Virgin queens of the fire ant,Solenopsis invicta Buren, that were removed from the influence of the inhibitory queen pheromone, dealated more readily in the presence of workers than in their absence. During 72 hours after disinhibition, a significantly greater number of overwintered virgin queens than spring-reared virgin queens dealated when they were isolated, but the numbers that dealated in the presence of workers were very similar. Some sexually immature virgin queens dealated after disinhibition. Virgin dealates were found to be capable of preventing other virgin queens from dealating. The various factors that influence dealation by virgin queens were used to develop a bioassay for the inhibitory queen pheromone ofS. invicta.

Toutes les espèces étudiées ont suivi les pistes des autres à une seule exception. Cependant, lorsque nous avons donné aux Fourmis le choix entre deux pistes distinctes, nous avons montré qu'il y avait des différences dans le contenu du sac à venin de trois espèces. Nous avons étudié les réponses de 24 espèces de Fourmis et d'une espèce de Termite à une phéromone de piste deAtta texana (Buckley).
    Notes: Summary Interspecific trail following activity of poison sac contents from four species of leaf-cutting ants was investigated. With only one exception, all the species tested followed trails made from each others poison sac contents. However when the ants were given a choice of following one of two separate trails, clear differences were shown in the poison sac contents of the three species tested. The responses of 24 species of ants and one species of termite to anAtta texana (Buckley) trail pheromone were tested.
