    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.

    Optimized production of the acylium diagnostic ions in the chemical ionization NO+ mass spectra of long-chain monoolefins (1990)

    Notes: A recent reinvestigation of the reactivity of NO+ towards straight-chain monoolefinic compounds revealed that the characteristic acylium ions, previously reported for alkenyl acetates and related compounds, could also be obtained from alkenes and alkenoic acids (or esters). In this study, the influence of the sample pressure and that of NO on the production of the acylium ions was investigated, leading to disappearance graphs indicative of a strong dependence on these experimental factors. This gives a further explanation for previous apparent discrepancies in the literature and the optimum conditions of use for double-bond location in a variety of substituted or unsubstituted monoolefins.
