    Description / Table of Contents: Abstract The hexanic extracts from pheronomal glands of T. jacobaeae virgin females have been studied. Gas-chromatographic and mass-spectrometric analyses of the main component (no 1) (98%) in combination with behavioral and electrophysiological bioassays allowed us to determine its structure and absolue configuration: (Z,Z)-3,6-Cis-(S,R)9,10-epoxyheneicosadiene previously described in other Arctiid moths. A minor constituent (no 2) (1.5%) was identified as (Z,Z)-3,6-Cis-(S,R)9,10-epoxyeicosadiene by comparison with synthetic compound. This structure is a new one for a lepidoptera sex pheromone. The third component (no 3) of the same extracts has the same physico-chemical data as those of a previously reported constituent of another Arctiid moth: (Z,Z,Z)-3,6,9 heneicosatriene.
    Notes: Abstract Les analyses physico-chimiques d'extraits hexaniques de glandes à phéromone de femelles vierges de T. jacobaeae, associées à des études du comportement sexuel et à l'électroantennographie, ont permis d'identifier le composé majoritaire (98%) comme étant l'époxy-9S,10R-(Cis)-hénéicosadiène-3Z,6Z (no 1) et de déterminer sa configuration absolue. Les analogies entre les spectres du composé no 2 (1,5%) et ceux de l'époxy-9S,10R éicosadiène-3Z,6Z de synthèse nous conduisent à proposer cette structure pour ce constituant minoritaire. Le troisième produit (0,5%) possède les caractéristiques physico-chimiques de l'hénéicosatriène-3Z,6Z,9Z (no 3). Les produits 1 et 3 ont déjà été identifiés comme constituants de phéromones d'Arctiidae tandis que le produit 2 est décrit ici pour la première fois dans une sécrétion phéromonale de Lépidoptère.

    Notes: Summary Pheromonal secretions produced by females and males of the noctuid moth,Mocis megas (Guénée) have been analyzed by gas chromatography and mass spectrometry (EI (electron impact) and CI (chemical ionization)). The female sex pheromone was a blend of (Z,Z,Z) 3,6,9 heneicosatriene (55%) and (Z,Z) 3,6-cis-9S, 10R-epoxyheneicosadiene (45%). Male secretion produced at the level of a prothoracic organ was a blend of two unsaturated major hydrocarbons: (Z,Z) 6,9 heneicosadiene, (64%) and (Z,Z,Z) 3,6,9 heneicosatriene (24%) and C19, C20 and C22 homologues (total ratio 12%), as minor components. The trienic hydrocarbon was present in both sexes. The behavioral role of this male secretion has not yet been elucidated.
