Pheromone-XLII. 1,3,6,9-nonadecatetraen, das sexualpheromon des frostspanners operophtera brumata (geometridae).

Abstract By means of GC and GCMS analysis and electrophysiological investigations ( z 3, z 6, z 9)-1,3,6,9-nonadecatetrane was identified as sex pheromone of the winter moth O . brumata , and prepared by stereoselective synthesis methods.

Pheromone XII. Männchenduftsoffe von Noctuiden (Lepidoptera)

By gaschromatographic-mass spectrometric methods 2-phenylethyl alcohol, benzylalcohol, phenylacetaldehyde and benzaldehyde were identified from scent brushes of male Noctuidae species (Lepidoptera).By gaschromatographic-mass spectrometric methods 2-phenylethyl alcohol, benzylalcohol, phenylacetaldehyde and benzaldehyde were identified from scent brushes of male Noctuidae species (Lepidoptera).

Pheromone XXX. Identifizierung eines neuartigen Pheromonkomplexes aus der Graseule Scotia exclamationis (Lepidoptera).

Zusammenfassung Mittels Gaschromatographie und GC-Massenspektrometrie wurden (Z)-5-Tetradecenylacetat und (Z)-9-Tetradecenylacetat als Pheromonkomplex bei der Graseule identifiziert.

Identification of Three Sex Pheromone Components of the Female Saturniid Moth Antheraea pernyi (Lepidoptera: Saturniidae)

Abstract By means of electroantennography and single cell recordings, GC and GCMS analyses and GC analysis with EAG detection (6E,11 Z)-6,11-hexadecadienal, (6E,11 Z)-6,11-hexadecadienyl acetate and (4E,9Z)-4,9-tetradecadienyl acetate were identified as the primary components of the sex pheromone of female Antheraea pernyi (Lepidoptera: Saturniidae).

(Z)-9-dodecenyl acetate, a component of the sex pheromone of Cnephasia longana Haworth (Lepidoptera: Tortricidae)

Abstract By means of electrophysiological investigations, GC- and GCMS-analysis of gland extracts and GC-analysis with EAG-detection (Z)-9-dodecenyl acetate was proven to be a component of the sex pheromone of female Cnephasia longana moths. (E)-9-dodecenyl acetate acts as a pheromone inhibitor, as shown by field trials.

Pheromone 84 [1]. Der Sexualpheromonkomplex des „Braunen Bären“ Arctia caja (Lepidoptera: Arctiidae) / Pheromones, 84 [1]. The Sex Pheromone Complex of the Arctiid Moth Arctia caja (Lepidoptera: Arctiidae)

Abstract By means of GC, GC/MS and GC-coupled electroantennogram techniques, (3Z,6Z,9Z)- 3,6,9-heneicosatriene (1), (3Z,6Z)-m-9,10-epoxyheneicosadiene (2) and (3Z,6Z)-cis-9,10- epoxyeicosadiene (3) were structurally elucidated as the biologically active components of the pheromone complex of Arctia caja (Lepidoptera: Arctiidae).
