    Anthophora Bees: Unusual Glycerides from Maternal Dufour's Glands Serve as Larval Food and Cell Lining (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-03-07
    Description: The Dufour's gland of Anthophora abrupta, a solitary bee, secretes a complex mixture of liquid triglycerides containing one long-chain and two shortchain fatty acids. This is applied inside the earthen brood cells and added to the provision, where it is converted, perhaps by enzymes from the bee's saliva or gut, to solid diglycerides that are later eaten by the bee larvae. This use of Dufour's gland secretion as food and its nutritive function are reminiscent of the royal jelly secreted by honey bees.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Norden, B -- Batra, S W -- Fales, H M -- Hefetz, A -- Shaw, G J -- New York, N.Y. -- Science. 1980 Mar 7;207(4435):1095-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17759841" 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〉

    Chemistry of cephalic secretion of fire beeTrigona (Oxytrigona) tataira (1984)
    Springer
    Journal of chemical ecology 10 (1984), S. 451-461 
    Details
    ISSN: 1573-1561
    Keywords: Fire bee ; Trigona (Oxytrigona) tataira ; Hymenoptera ; Apidae ; mandibular gland secretion ; enediones ; monoketones ; carboxylic esters ; hydrocarbons ; E-3-hepten-2,5-dione ; E-3-nonen-2,5-dione

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Analysis of the volatile compounds derived from cephalic glands of the fire beeTrigona (Oxytrigona) tataira by GC-MS was undertaken. The following compounds were readily identified: hydrocarbons:n-C11H24,n-C13H28,n-C14H30,n-C15H32,n-C17H36,n-C23H48,n-C15H30,n-C17H34,n-C21 H42, andn-C23H46; carboxylic acids: palmitic acid, linoleic acid, linolenic acid, stearic acid, and oleic acid; carboxylic esters: dodecyl acetate, tetradecyl acetate, hexadecyl acetate, octadecyl acetate, and dodecyl decanoate; monoketones: 5-hepten-2-one, 3-hepten-2-one, 2-heptanone, and 5-nonen-2-one. Two major components of the mixture were identified asE-hepten-2,5-dione andE-3-nonen-2,5-dione. Structures of these novel compounds were suggested by their GC-MS behavior and the GC-MS behavior of their dimethoximes and proved by comparison with authentic synthetic samples. Trace amounts of the corresponding Z isomers and the saturated analogs, heptan-2,5-dione and nonan-2,5-dione, were also found. The possible functions of these glandular constituents are discussed.

    Mandibular gland allomones ofDasymutilla occidentalis and other mutillid wasps (1980)
    Springer
    Journal of chemical ecology 6 (1980), S. 895-903 
    Details
    ISSN: 1573-1561
    Keywords: Dasymutilla occidentalis ; Dasymutilla ; Timulla ; Pseudomethoca ; Smicromyrme ; Traumatomutilla ; Pappognatha ; Hymenoptera ; Mutillidae ; 4-methyl-3-heptanone ; 4,6-dimethyl-3-nonanone ; 4,6-dimethyl-3-octanone ; allomones

    Notes: Abstract The mandibular gland secretion of the mutillid wasp,Dasymutilla occidentalis, possesses three short-chained ketones-4-methyl-3-heptanone (4MH), 4,6-dimethyl-3-nonanone (4,6DMN), 4,6-dimethyl-3-octanone (4,6DMO)—and several unidentified compounds. This is the first report of 4,6DMN as a natural product and its synthesis is described. These ketones, which are either known to be ant alarm pheromones or are structurally very similar to ant alarm pheromones, appear to function as allomones against ants, major potential predators of mutillid wasps. The major secretory component, 4-methyl-3-heptanone, which was identified in females and/ or males of the species analyzed within the generaDasymutilla, Timulla, Traumatomutilla, andPappognatha, appears to constitute a chemical character of the defensive secretions of these genera.

    Venom chemistry of ants in the genusMonomorium (1982)
    Springer
    Journal of chemical ecology 8 (1982), S. 285-300 
    Details
    ISSN: 1573-1561
    Keywords: Monomorium spp. ; Hymenoptera ; Formicidae 2,5-dialkylpyrrolidines ; ant venom alkaloids ; methoxymercuration-demercuration ; chemotaxonomy
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract A comparative analysis of the venomous alkaloids produced by ant species in the subgenusMonomorium of the genusMonomorium has been undertaken. All species produce mixtures of unsymmetricaltrans-2,5-dialkylpyrrolidines, but the proportions of the constituents may vary considerably between species. All alkaloids contain both C6 and C9 side chains which are present as C9-saturated. C6-monounsaturated, and both C6-and C9-monounsaturated dialkylpyrrolidines. The structure of 2-(1-hex-5-enyl)-5-(1-non-8-enyl)pyrrolidine, a previously undescribed alkaloid, was proved by unambiguous synthesis after the location of the double bonds was established by the methoxymercuration-demercuration followed by mass spectrometry. The possible chemotaxonomic significance of the mixtures of venomous alkaloids produced by these species ofMonomorium is discussed.
