“…Earlier records have found (3Z,6Z,9Z)-3,6,9-nonadecatriene to work synergistically or to be a pheromone precursor. Trap catches of both Alsophila pometaria Harris in Canada (Wong et al 1984) and Peribatodes rhomboidaria Denis & Schiffermüller in Hungary and Switzerland (Tóth et al 1987) increased significantly when the triene was added to two tetraenes and one ketone (the main pheromone components), respectively. Similarly, in field trapping in Hungary for three other geometrids (Colotois pennaria Linnaeus, Erannis defoliaria Clerck and Agriopis marginaria Fabricius), adding the triene to the main component produced a more attractive lure than the main component alone (Szöcs et al 1993).…”

The autumn gum moth, Mnesampela privata (Guenée) (Lepidoptera: Geometridae), is native to Australia and can be a pest of plantation eucalypts. Field-collected and laboratory-reared female autumn gum moths were dissected to remove glands likely to contain components of the sex pheromone. Using gas chromatography (GC) and combined gas chromatography-mass spectrometry (GC-MS), three compounds were identified from female extracts, namely (3Z,6Z,9Z)-3,6,9-nonadecatriene, 1-hexadecanol and 1-octadecanol (confirmed by comparison with synthetic samples). Nonadecatriene elicited an antennal response in male autumn gum moth during gas chromatographic analyses combined with electroantennographic detection (GC-EAD). In electroantennogram (EAG) recording male M. privata antennae responded to the nonadecatriene. Nonadecatriene was synthesised via Kolbe electrolysis, starting with (9Z,12Z,15Z)-octadeca-9,12,15-trienoic acid (linolenic acid) and propanoic acid or via an alternative four-step method also starting from linolenic acid. In field trials (3Z,6Z,9Z)-3,6,9-nonadecatriene proved attractive to male moths. Thus, we conclude that (3Z,6Z,9Z)-3,6,9-nonadecatriene is a sex pheromone component of autumn gum moth. This component has been identified in extracts from other geometrids in the same subfamily, Ennominae. However, to our knowledge this is the first example where (3Z,6Z,9Z)-3,6,9-nonadecatriene has been found in females and also proved attractive to male moths when presented on its own. Our results are discussed in relation to other geometrid pheromones.

(Z,Z,Z)-3,6,9-nonadecatriene (Z3,Z6,Z9-19Hy) and (Z,Z)-3,9-cis-6,7-epoxy-nonadecadiene (Z3,Z9-cis-6,7-epo-19Hy) were identified in pheromone gland extracts from femaleErannis defoliaria. The two components were found in a 1∶3 ratio, with the main component,Z3,Z9-cis-6,7-epo-19Hy present at an amount of about 1.5 ng per female. The components were identified by means of gas chromatography-mass spectrometry, gas chromatography-electroantennography and gas chromatography-single sensillum recordings. Single sensillum measurements on the male antenna showed two physiological types of sensilla. One type was characterized by a large spike amplitude cell responding toZ3,Z9-cis-6,7-epoxy-19Hy and a small spike amplitude cell responding toZ3,Z6,Z9-19Hy. A second type responded only with a large spike amplitude cell to the epoxide, and this cell was inhibited by the triene. Of the two pheromone components, the epoxide gave the higher response in the EAG tests. Preliminary field tests support the identification of the pheromone components. The epoxide was also found to be present in the extract of the pheromone gland ofColotois pennaria, and males ofC. pennaria andAgriopis marginaria were trapped by the mixture of the identified compounds.

(Z)‐7‐Dodecenol attractive to male Agrotis segetum Den. & Schiff. (Lep., Noctuidae) in the field

Male turnip moths (Agrotis segetum) are attracted to higher dosages of (Z)‐7‐dodecenol, which compound has not been described among the behaviorally active pheromone components of the species. This attraction is enhanced by the addition of (Z)‐5‐decenol. Indirect evidence is presented suggesting that the alcohols are in some way mimicking the effect of the corresponding acetates, known as pheromone components. This case strongly indicates that, care must be taken when field screening data gained with synthetic compounds are related to the composition of sex pheromones. Zusammenfassung Zur Lockwirkung von (Z)‐7‐Dodezenol auf Wintersaateulen‐Männchen, Agrotis segetum Den. & Schiff. (Lep., Noctuidae) im Freiland Die Männchen der Wintersaateule (Agrotis segetum) werden durch höhere Dosen von (Z)‐7‐Dodezenol in Klebefallen angelockt. Diese Verbindung wurde unter den ethologisch aktiven Pheromonkomponenten dieser Eulenart nicht beschrieben. Die Anlockungsaktivität wird durch das Zugeben von (Z)‐5‐Dezenol erhöht. Die obigen Ergebnisse sind ein indirekter Beweis dafür, daß die Alkohole die verhaltensbeeinflussende Wirkung der homologen Azetate nachahmen können. Dieser Fall zeigt klar, daß synthetische Verbindungen, die in Feldversuchen attraktiv wirken, nicht unbedingt als Pheromonkomponente zu betrachten sind.
