    Notes: Summary Fatty acyl moieties present in the female sex pheromone gland of the lightbrown apple moth,Epiphyas postvittana, include the analogues of the two sex pheromone components, (E)-11-tetradecenyl acetate and (E,E)-9,11-tetradecadienyl acetate. Application of deuterium-labelled fatty acids followed by analysis by gas chromatographymass spectrometry showed that biosynthesis of the two pheromone components involved initial Δ11-desaturation of myristic and palmitic acids respectively.

    Notes: Abstract Sex pheromone behavioral responses were analyzed in a flight tunnel with European corn borer,Ostrinia nubilalis (Hübner), males from three distinct populations. Males from a bivoltine and a univoltine biotype using a 97.8∶2.2 blend (Z strains) of (Z)- and (E)-11-tetradecenyl acetate were assayed with treatments containing 0, 0.5, 1, and 3% of theE isomer. Males from neither population oriented in the plume to the 100%Z treatment, but bivoltine males oriented and flew to the source to the other three treatments, whereas univoltine males oriented and flew to the source only to the 1 % and 3 %E treatments. Males from a bivoltine biotype using a 1∶99 blend ofZ/E isomers (E strain) were assayed with sources containing 0, 0.5, 1, and 3% of theZ isomer. Males did not orient to the 0%Z source, but oriented and flew to the source to the other three treatments. In addition to using opposite geometric isomers for the main pheromone component, the bivoltineE strain differed from the bivoltineZ strain by producing and responding better to 1 % of the minor component and by storing 3 times more pheromone in the female glands. Contrary to previous reports, the blend of two pheromone components is significantly better than the main component alone in eliciting oriented flight and close-range behavior with males from all three populations of European corn borer.

    Notes: Abstract MaleArchips argyrospilus (Walker) were maximally attracted to a 60∶40∶4∶200 admixture of (Z)-11-tetradecenyl, (E)-11-tetradecenyl, (Z)-9-tetradecenyl and dodecyl acetates. The identification of (Z)-9-tetradecenyl acetate, in addition to the other 3 components reported previously, is the first report of a 4-component pheromone system in moths.Archips mortuanus Kearfoot, a sibling species, was maximally attracted to a blend of the same components, but in a 90∶10∶1 mix of the tetradecenyl acetates. Among a number of tortricine moths that co-occur on apples and other hosts in New York, British Columbia, and elsewhere, differences in diel rhythms of attraction and seasonal distribution are insufficient to maintain reproductive isolation. Although the attractant systems of these species often possess components in common, males are maximally attracted to a speciesspecific blend. In tortricine moths attraction specificity appears to be a paramount mechanism for species partitioning.

    Notes: Abstract Female tip extracts of the variegated leafroller moth,Platynota flavedana (Clemens), were analyzed and found to contain a mixture of (E)-11-tetradecen-1-ol and (Z)-11-tetradecen-1-ol (9∶1), as well as a mixture of (E)-11-tetradecenyl acetate and (Z)-11-tetradecenyl acetate (2-3∶1). Small amounts of tetradecen-1-ol and tetradecyl acetate probably are also present. In the field, a mixture of the two alcohols (84∶16,E∶Z ratio) attracted significantly more male moths of this species than any other mixture tested. The data indicate that the acetates are probably not used as pheromone components.

    Threshold hypothesis for pheromone perception (1978)
    Springer
    Journal of chemical ecology 4 (1978), S. 685-699

    Notes: Abstract Field results have shown that male moths of some species are not always trapped by the ratio of pheromone components produced by the female moths. For cases involving a binary mixture of geometrical or positional isomers, this phenomenon may be explained by use of a threshold diagram in which the isomer ratio in the mixture is plotted against release rate (concentration). In this diagram an “attraction area” is bounded by the threshold for flight activation over the full range of binary mixtures and by the threshold for alteration of in-flight behavior (disorientation) by each pheromone component. A low release rate of the natural mixture may fall within this “attraction area,” or a high release rate of mixtures in certain other ratios may fall within this area and would be expected to attract male moths. This hypothesis has been used to explain heretofore anomalous trapping data with some moth species, and it can be useful in future studies on defining pheromone blends, species specificity, and potentially disruptive mixtures for insect control.

    Notes: Abstract (E)-9,11-Dodecadienyl acetate and (Z)-9,11-dodecadienyl acetate in conjunction with (E)-11-tetradecenyl acetate and (Z)-11-tetradecenyl acetate were found to comprise the sex pheromone ofSparganothis directana, based on chemical analysis, electroantennogram tests, and field trapping. (E)-9-Dodecenyl acetate and (Z)-9-dodecenyl acetate were also found in gland extracts but did not influence trap catches. The relative amounts of these compounds in the gland were 35∶2∶19∶28∶ 10∶6, in the order named. Only (E)-9,1 1-dodecadienyl acetate, (E)-11-tetradecenyl acetate, and (Z)-11-tetradecenyl acetate were required for attraction of males to traps, dispensed in the relative amounts 50∶12∶38, respectively.

    Male moth sensitivity to multicomponent pheromones: Critical role of female-released blend in determining the functional role of components and active space of the pheromone (1986)

    Notes: Abstract In the present study male redbanded leafroller (Argyrotaenia velutinana), cabbage looper (Trichoplusia ni), and Oriental fruit moths, (Grapholita molesta), were tested in a flight tunnel to (1) the major pheromone component, (2) theZ/E pheromone component mixtures for Oriental fruit moth and redbanded leafroller, (3) and the female-released blends, over a series of dosages. Experiments were designed to test the hypothesis that male response downwind of a female is initiated by the major component and that minor components function only to elicit behaviors close to the female during close-range approach and courtship. The results did not support this hypothesis, but rather showed that males initiated upwind flight in significantly higher percentages to the complete blends of components, at all dosages, compared to single components or partial blends. Addition of minor components also signficantly enhanced male perception of the major component at lower dosages, resulting in completed flights to dosages of the major component that alone did not elicit any upwind flight. Our results support the concept that minor components function to enhance male sensitivity to the pheromone, and the specificity of the signal. Our results also support the hypothesis that the active space of the pheromone is a function of the upper and lower concentration thresholds for the blend of components, and not simply for the major component.

    Notes: Abstract The pheromone ofArgyrotaenia velutinana (Walker) is a 92∶8∶150 mixture of (Z)-11-, (E)-11-tetradecenyl and dodecyl acetates. An 85∶15 blend of (Z)-11- and (E)-11-tridecenyl acetates produces a trap catch equivalent to that with the pheromone blend. The sensory input elicited by (Z)-11-tridecenyl acetate appears to substitute for the sensory input of both (Z)-11-tetradecenyl and dodecyl acetates, whereas the input from (E)-11-tridecenyl acetate appears to substitute for that of (E)-11-tetradecenyl acetate. Surprisingly, addition of dodecyl acetate to the tridecenyl acetates mixture decreases trap catches.

    Notes: Abstract The design, construction, and uses of a relatively simple and inexpensive wind tunnel for studying responses of flying insects to sex pheromones are presented with special reference to research on moths. A variable-speed continuous belt installed on the tunnel floor proved to be a valuable feature, allowing the observer to manipulate the speed of the responding insect and thus to measure the duration and persistence of sustained anemotactic flights in the pheromone plume. It is concluded that flight tunnels of this kind will prove to be extremely valuable multipurpose tools in pheromone research.

    Notes: Abstract Males of the redbanded leafroller,Argyrotaenia velutinana (Walker) (Lepidoptera: Tortricidae), were studied for their behavioral responses in laboratory olfactometers and in the field to the 3 components of the female-produced sex pheromone:cis-11-tetradecenyl acetate (c11–14∶Ac),trans-11-tetradecenyl acetate (t11–14∶Ac), and dodecyl acetate (12∶Ac). Dodecyl acetate, when evaporated with c11–14∶Ac (8%trans) in the field, modified the behavior of feral males nearby the chemical source, causing an increase in the frequency of landing and close approach to the pheromone dispenser. Apparently, an inflight behavioral modification concerning landing or not landing occurs within 60 cm of the source and is mediated by 12∶Ac. In laboratory olfactometers, c11–14∶Ac (8%trans) demonstrated a lower threshold for male activation than pure c11- and t11–14∶Ac and blends of the two isomers. Additionally, over a wide range of dosages, males responded with optimum wing-fanning response to c11–14∶Ac (8%trans) compared to pure c11–14∶Ac, c11–14:Ac (30%trans), and pure t11–14∶Ac, suggesting that thecis∶trans ratio rather than absolute amounts of either isomer, is a crucial factor in eliciting male response. When presented with c11–14∶Ac (8%trans) (1∶1), dodecyl acetate caused a significant prolongation of wing-fanning over c11–14∶Ac (8%trans) alone and resulted in a greater percentage of males moving upwind to the source. Since the increase in wing-fanning and orientation occurred at higher concentrations of the 3-component mixture, the effect of 12∶Ac in the laboratory may reflect the close-range role of 12∶Ac in the field.
