Abstract
Sexually deceptive orchids employ mimicry of insect sex pheromones to exploit a diverse group of pollinators. The chemical structures of five semiochemicals (1–3, 7, 8) produced by populations of the warty hammer orchid, Drakaea livida, pollinated by a thynnine wasp in the genus Catocheilus were elucidated. With the exception of (2, 5-dimethylpyrazin-3-yl) methyl 3-methylbutanoate (7), all active compounds were tetrasubstituted pyrazines, including ...
