With the use of deuterium‐labeled saturated fatty acids coupled with gas chromatography‐mass spectrometric analysis, biosynthesis of the sex pheromone component (Z)‐8‐tetradecenyl acetate in the greenheaded leafroller moth Planotortrix excessana was shown to proceed via Δ10 desaturation of palmitate. The resultant (Z)‐10‐hexadecenoate is two carbon chain‐shortened to the precursor (Z)‐8‐tetradecenoate. The minor component (Z)‐10‐tetradecenyl acetate is biosynthesized by Δ10 desaturation of myristate. This is the first confirmation of Δ10 desaturation in an eukaryotic system.
