Abstract

A major sex attractant released by the virgin female of the horse-chestnut leafminer Cameraria ohridella Deschka et Dimic (Lepidoptera: Gracillariidae) which devastates horse-chestnut trees in Europe, was identified in picogram quantities as (8E,10Z)-tetradeca-8,10-dienal without using spectral methods. The identification solely relied on gas chromatography with electroantennographic detection (GC-EAD), calculation of Kovats' indices of the active principle on different GC phases, and construction of antennal response spectra (EAG response profiles) to C-12 and C-14 saturated and unsaturated standards with different functional groups. The dienal was prepared by a stereospecific synthesis and shown to be highly active for conspecific males in pg amounts and Fully comparable to the natural substance. (C) 1999 Elsevier Science Ltd.
