    Polyunsaturated hydrocarbons in the stable fly (1985)

    Notes: Abstract Three triply-unsaturated hydrocarbons were identified from cuticular lipids of male and mixed-sex stable flies,Stomoxys calcitrans. The major compound, (Z,Z)-1,7,13-pentacosatriene, and two minor compounds, (Z,Z)-1,7,13-tetracosatriene and (Z,Z)-1,7,13-tricosatriene, were synthesized. Samples of male and female stable flies that differed in age, seasonality, geographic origin, rearing conditions of adults, and methods of extraction were analyzed for the presence of these triolefins. Females were found to have small quantities of the same C25 triolefin, which appeared to be identical to that in males. No evidence was seen for attraction of males or females to natural or synthetic triolefins.

    Compared behavioral responses of maleDrosophila melanogaster (Canton S) to natural and synthetic aphrodisiacs (1985)
    Springer
    Journal of chemical ecology 11 (1985), S. 1617-1629 
    Details
    ISSN: 1573-1561
    Keywords: Drosophila melanogaster ; Diptera ; Drosophilidae ; aphrodisiac pheromone ; recognition pattern ; cuticular hydrocarbons ; heptacosadienes ; mass spectrometry

    Notes: Abstract Cuticular aphrodisiacs fromD. melanogaster females were further characterized and the male response specificity towards such natural and synthetic unsaturated hydrocarbons was investigated. The behavioral activity seems to be correlated with some chain-length requirement and double-bond position; at least one double bond in position 7 seems necessary. This position is more abundant among natural monoenes, and among dienes which also bear a second double bond in position 11, whatever the chain length. Bioassays of the synthetic (Z,Z)-7,11-heptacosadiene yielded a dose-response curve close to that of the natural mixture of heptacosadienes in which the 7–11 isomer is predominant. This female specific 7,11 heptacosadiene appears to be the most potent aphrodisiac for males of the species. Its threshold is lower than that of both 7,11-nonacosadiene and 7-pentacosene which might also play a role in sex and species recognition.

    Identification of the cuticular hydrocarbons of the horn fly and assays for attraction (1981)
    Springer
    Journal of chemical ecology 7 (1981), S. 669-683 
    Details
    ISSN: 1573-1561
    Keywords: Horn fly ; olefins ; mating pheromone ; paraffins ; Musca autumnalis ; sex attractant
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Horn fly cuticular paraffin and monoolefin hydrocarbons were chemically identified and assayed for biological activity as attractants. The majority of the paraffins were odd-numbered, straight-chain molecules 21–29 carbons in length; much smaller amounts of even-numbered, straightchain molecules 22–28 carbons in length and methyl-branched compounds were also present. At least 80% of the monoolefin consisted of straight-chain molecules 23, 25, and 27 carbons in length, two of which have been identified as sex pheromones in other muscoid species. The hydrocarbon profiles among sexes and strains (laboratory and wild) were very similar except for wild females, which showed quantitative differences from the other sources. However, only females showed significant (albeit low) responses to some test materials, both synthetic and natural, and activity appeared to be centered in the monoolefins.

    Cuticular hydrocarbons from six species of tephritid fruit flies (1986)
    New York, NY [u.a.] : Wiley-Blackwell
    Archives of Insect Biochemistry and Physiology 3 (1986), S. 397-412 
    Details
    ISSN: 0739-4462
    Keywords: cuticular hydrocarbons ; alkanes ; Tephritidae ; fruit flies ; larvae ; adults ; mass spectra ; Chemistry ; Food Science, Agricultural, Medicinal and Pharmaceutical Chemistry
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Biology
    Notes: Cuticular alkanes obtained from larvae and adults of six species of tephritid fruit flies, Anastrepha ludens, A. suspensa, Ceratitis capitata, C. rosa, Dacus cucurbitae, and D. dorsalis were analyzed by gas chromatography. The same four major alkanes were shown to be present by capillary GC-mass spectra in all Anastrepha and Ceratitis larvae. Profiles were obtained from individual larvae and adult specimens that showed statistical differences between species, whereas profiles of conspecific life forms including pupae of A. suspensa from different locations showed some similarities. Sexual dimorphism was not observed in alkanes extracted from adults. A novel series of alkadienes was found in all Anastrepha and Ceratitis but not in Dacus.
