    Notes: Abstract Components of a sex pheromone that cause male face flies to strike at females were found to be the straight-chain monoalkenes (Z)-14-nonacosene, (Z)-13-nonacosene, and (Z)-13-heptacosene. Although these compounds were found in the extracts of both sexes, extracts from sexually mature males contained a much higher proportion of nonacosane and heptacosane, which attenuated the activity of the active monoalkenes. The monoalkenes were readily synthesized by a Wittig reaction modified by the use of hexamethylphosphoric triamide as a cosolvent with tetrahydrofuran to produce a product containing 94–96% (Z) isomer.

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Cuticular rinses of the female stable fly,Stomoxys calcitrans (L.), contained saturated and unsaturated hydrocarbons that incited the male fly to attempt couplation. These compounds present in GLC trappings of the saturated hydrocarbon fraction showing highest biological activity were mono- and dimethyl-substituted hentria- and tritriacontanes. Active trappings from the unsaturated hydrocarbon fraction contained (Z)-9-hentriacontene, (Z)-9-tritriacontene, and methyl-branched hentria- and tritriacontenes.

    Notes: Abstract Each of 20 methyl-branched and 1,5-dimethyl-branched alkanes that comprise the active principle of saturated hydrocarbons of the female stable fly,Stomoxys calcitrans (L.), was synthesized and evaluated for mating stimulant activity. The compounds that showed the highest degree of activity in bioassays were 15-methyl- and 15,19-dimethyltritriacontanes.

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Chromatograms of the cuticular lipids washed from recently emerged female and maleFannia canicularis (L.) flies were nearly identical, but by the time the flies were 5 days old, the cuticular components of the two sexes differed considerably. A monoolefin which constituted 66% of the cuticular lipid from 5-day-old females stimulated a copulatory response from males and was identified as (Z)-9-pentacosene. The cuticular lipid of the same age males contained only 1% of this compound. Although all the major constituents of the cuticular lipid from mature females were hydrocarbons, 27% of the lipid washed from 5-day-old males was a nonhydrocarbon material that was represented by a single GLC peak. This material was identified as heneicosan-8-ol acetate.

    Keywords: Stable fly ; Stomoxys calcitrans (L.) ; pheromone ; sex pheromone ; polyene ; mating stimulant ; (Z,Z)-1,7,13-pentacosatriene
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract The four geometrical isomers of 1,7,13-pentacosatriene were synthesized from 1,7-octadiyne. Two of the required isomers were synthesized using known methodology. Hydrogenation of acetylenic linkages were employed to produce predominantly cis alkenes, and alkali metal/amine reduction was used to produce a trans alkene. It was thus possible to produce the (Z,Z) and the (Z,E) isomers. Methods for olefin inversion were then employed to obtain the other two isomers.

    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract The major component of the cuticular lipids of male stable flies,Stomoxys calcitrans (L.), was identified as (Z,Z)-1,7,13-pentacosatriene. The identification was confirmed by synthesis. This material is of unknown biological function; it is apparently not produced by female stable flies.
