Abstract
Larvae of Chilecomadia valdiviana (Lepidoptera: Cossidae) were extracted and the extract was fractionated by chromatography on silica. As shown by gas chromatography–mass spectrometry, the major fraction contained saturated and unsaturated straight-chain acetates, with (Z )-5,13-tetradecadienyl acetate and dodecyl acetate as the main components, while in a minor fraction the corresponding alcohols were detected. The identification of the compounds and the synthesis of some reference material are presented.
