Male‐specific volatile components, released by the dried bean beetle, Acanthoscelides obtectus , were identified as methyl ( E , R )‐2,4,5‐tetradecatrienoate, methyl (2 E ,4 Z ,7 Z )‐2,4,7‐decatrienoate, methyl (2 E ,4 Z )‐2,4‐decadienoate, octadecanal and the sesquiterpenes (3 Z ,6 E )‐ and (3 E ,6 E )‐α‐farnesene. In olfactometer bioassays, pure methyl ( E , R )‐2,4,5‐tetradecatrienoate was only weakly attractive to unmated females. However, a blend of the six identified compounds released in physiologically relevant ratios and doses proved to be as active as headspace odours collected from live males.
