    Sex pheromone components of female Cornutiplusia circumflexa (1991)
    Springer
    Entomologia experimentalis et applicata 60 (1991), S. 167-172

    Notes: Abstract Capillary gas chromatography indicated the presence of (Z)-7-dodecenyl alcohol and (Z)-7-dodecenyl acetate in the abdominal tip extracts of female Cornutiplusia circumflexa (L.) (Lepidoptera: Noctuidae: Plusiinae) moths. Gas chromatography combined with mass spectrometry and dimethyl disulfide derivatization confirmed the structure of these two principal pheromone components. In a flight-tunnel bioassay, a 5:1 blend of alcohol and acetate elicited the complete courtship sequence by males. The response was comparable to that evoked by a live virgin female, but males spent significantly longer time at calling females than at the synthetic source. The 5:1 blend was also attractive to male C. circumflexa in the field, as indicated by catches in traps baited with this mixture. (Z)-7-dodecenyl alcohol alone was slightly attractive whereas (Z)-7-dodecenyl acetate alone was completely inactive. C. circumflexa is the first reported Plusiinae species which utilizes (Z)-7-dodecenyl alcohol as the major pheromone component.

    Double-bond location in monounsaturated fatty acids by dimethyl disulfide derivatization and mass spectrometry: Application to analysis of fatty acids in pheromone glands of four lepidoptera (1985)

    Notes: Abstract A rapid analytical procedure for the determination of the position of double bonds in mixtures of monounsaturated fatty acid methyl esters has been developed. The method is based on direct capillary GC-MS-EI analysis of dimethyl disulfide adducts. The procedure was applied to mixtures of monounsaturated fatty esters from pheromone gland extracts of three tortricids from theChoristoneura genus,C. fumiferana, C. occidentalis, andC. pinus pinus, and one noctuid from the Plusiinae subfamily,Plusia chalcites. A correlation was found between the known major pheromone components in the four species with the corresponding fatty acids. Some of the additional fatty acids may be precursors to as yet unidentified minor pheromone components, present in extremely small quantities, in these species.

    Identification of sex pheromone component of spruce budmothZeiraphera canadensis (1989)
    Springer
    Journal of chemical ecology 15 (1989), S. 2435-2444 
    Details
    ISSN: 1573-1561
    Keywords: Zeiraphera canadensis ; spruce budmoth ; (E)-9-tetradecenyl acetate ; sex pheromone ; Lepidoptera ; Tortricidae ; Eucosminae ; trapping
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract The analyses of virgin female sex pheromone gland extracts by gas chromatography (GC), GC-electroantennographic detection (GC-EAD) and GC-mass spectrometry (GC-MS) followed by field-trapping experiments, have identified (E)-9-tetradecenyl acetate (E9–14:Ac) as the primary sex pheromone component of the spruce budmoth,Zeiraphera canadensis. Dosages of 1.0–100.0 ⧎g ofE9–14:Ac impregnated in rubber septa provide effective trap baits.

    Sex pheromone of the tomato looper,Plusia chalcites (ESP) (1981)
    Springer
    Journal of chemical ecology 7 (1981), S. 1081-1088

    ISSN: 1573-1561
    Keywords: Plusia chalcites ; Lepidoptera ; Noctuidae ; tomato looper ; sex pheromone identification ; glass WCOT capillary chromatography ; gas chromatography-mass spectrometry ; Z-7-dodencenyl acetate ; Z-9-tetra-decenyl acetate

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Z-7-Dodecenyl acetate (A) andZ-9-tetradecenyl acetate (B), in a 5∶1 ratio, have been identified as sex pheromone components of femalePlusia chalcites. In addition, small amounts of dodecyl acetate, tetradecyl acetate, hexadecyl acetate, andZ-9-dodecenyl acetate have been found in the abdominal tip extracts. This is the first known Plusiinae species which utilizes a two-component primary sex pheromone system. The most effective lure found in field experiments was a mixture of 1 mg A and 0.2 mg B absorbed on rubber septa.
