    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 glands of stingless bees (Hymenoptera: Apidae): Chemical analysis of their contents and biological function in two species ofMelipona (1983)
    Springer
    Journal of chemical ecology 9 (1983), S. 1465-1472 
    Details
    ISSN: 1573-1561
    Keywords: Melipona ; Hymenoptera ; Apidae ; mandibular glands ; 2-heptanol ; skatole ; nerol ; undecane ; alarm response ; stingless bees
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Workers ofMelipona fasciata andM. interrupta triplaridis respond to their respective mandibular gland extracts with alarm recruitment and defensive behavior. Workers rapidly exit from the nest entrance, land on an intruding object, and bite with the mandibles while vibrating the flight muscles. These behaviors are accompanied by the release of the contents of the mandibular glands. Colonies of both species exhibited greater response to their own mandibular gland extracts than to those of other stingless bee species. Chemical analysis identified 2-heptanol as the major component in hexane extracts of each species. Undecane was a constituent of both species; skatole and nerol were identified only in extracts ofM. i. triplaridis.

    Chemistry and function of mandibular gland products of bees of the genusExoneura (Hymenoptera, Anthophoridae) (1983)
    Springer
    Journal of chemical ecology 9 (1983), S. 1525-1531 
    Details
    ISSN: 1573-1561
    Keywords: Exoneura ; Allodapini ; Hymenoptera ; bees ; defense ; mandibular glands ; ethyl decanoate ; salicylaldehyde ; 1,4-benzoquinone ; ester ; aldehyde ; quinone
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract FemaleExoneura richardsoni, E. bicolor, andE. bicincta (Hymenoptera: Anthophoridae) release a pungent, staining liquid from their mandibular glands upon disturbance. This secretion is primarily composed of ethyl dodecanoate, with lesser amounts of homologous ethyl and methyl esters, salicylaldehyde, and 1,4-benzoquinone. The secretion elicits vigorous grooming when topically applied to antennae ofFormica ants. The shared, unique combination of mandibular gland lipids of these threeExoneura species supports their monophyletic classification, while the presence of salicylaldehyde may associateExoneura (Allodapini) withPithitis (Ceratinini).

    Exocrine secretions of bees V. Terpenoid esters in the Dufour's secretions ofPanurginus bees (Hymenoptera: Andrenidae) (1983)

    ISSN: 1573-1561
    Keywords: Bees ; exocrine products ; mass spectrometry ; citronellyl citronellate ; citronellyl geranate ; geranial ; neral ; Dufour's gland ; mandibular gland ; Panurginus ; Hymenoptera ; Andrenidae
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract The volatile components of Dufour's gland extracts were analyzed in two species of HolarcticPanurginus bees:Panurginus pontentillae andP. atramontensis. Two terpenoid esters, citronellyl citronellate and citronellyl geranate, were identified inP. pontentillae, whereas only the latter was inP. atramontensis. Citronellyl citronellate was identified in pollen ball extracts ofP. pontentillae. Mandibular gland extracts from male and femaleP. pontentillae contained neral and geranial. The significance of the Dufour's gland secretion in andrenid systematics and its function in the Andrenidae are discussed.

    Identification of ant repellent allomone produced by social waspPolistes fuscatus (Hymenoptera: Vespidae) (1984)
    Springer
    Journal of chemical ecology 10 (1984), S. 1799-1807 
    Details
    ISSN: 1573-1561
    Keywords: Social wasp ; Polistes fuscatus ; Hymenoptera ; Vespidae ; Formicidae ; ant repellent ; defensive allomone ; fatty acid esters ; methyl myristate ; methyl palmitate
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Two active components were isolated from the ant repellent secretion produced by glandular cells on the sixth (terminal) gastral sternite ofPolistes fuscatus (F.) females. One of the components was identified as methyl palmitate. Field bioassays with synthetic methyl palmitate showed it had repellent activity againstSolenopsis geminata (F.)Forelius pruinosus (Roger), andPheidole sp. The effectiveness of the repellent was greater againstF. pruinosus andPheidole sp. than againstS. geminata. Four methyl ester homologs of methyl palmitate also were field tested for repellent activity: methyl myristate had repellent activity against all three ant species, whereas methyl stearate, methyl linoleate, and methyl linolenate exhibited no repellency.

    The chemical feeding ecology ofNeodiprion dubiosus schedl,N. rugifrons midd., andN. lecontei (Fitch) on jack pine (Pinus banksiana lamb.) (1984)

    Notes: Abstract Two monophagous sawflies,Neodiprion dubiosus andN. rugifrons, actively avoid feeding on the current season's needles of jack pine,Pinus banksiana, while the polyphagousN. lecontei feeds indiscriminately on foliage of all age classes. Bioassay studies with needle extracts indicate thatN. dubiosus andN. rugifrons larval feeding preference is governed by a group of tricyclic diterpene resin acids. Resin acids commonly occur in needles of all ages; however, levopimaric, palustric, dehydroabietic, and neoabietic acids were at higher concentrations in the new needles.N. dubiosus was significantly deterred from feeding on 1-year-old foliage when treated with the pure resin acids, palustric and levopimaric, at 0.5 and 1.0 mg/ml MeOH.N. rugifrons larvae were deterred from feeding by pure dehydroabietic, neoabietic, and palustric acids at 1.0 mg/ml MeOH.
