ABSTRACT
The major and possibly only component of the sex attractant pheromone of the moth Hemileuca nevadensis (Lepidoptera Saturniidae) from southern California was determined to be (E10,Z12)-hexadecadienal (E10,Z12-16Ald). Detectable quantities of the analogs (E10,Z12)-hexadecadien-1-yl acetate (E10,Z12-16Ac) and (E10,Z12)-hexadecadien-1-ol (E10,Z12-16OH) were also present in solvent extracts of sex pheromone glands, and stimulated male antennae in coupled gas chromatography-electroantennogram detector (GC-EAD) assays. GC-EAD traces from solid phase microextraction (SPME) wipe samples of sex pheromone glands of calling females confirmed the presence of E10,Z12-16Ald and traces of E10,Z12-16OH on the gland surface, but E10,Z12-16Ac was not detected. Despite evidence for the presence of all three compounds in extracts, behavioral responses to synthetic compounds in the field suggested that only E10,Z12-16Ald is required for optimal attraction.
