GC‐EAD and GC‐MS analysis of pheromone gland extracts of sugarcane borer, Diatraea saccharalis , revealed two antennally active compounds, (9 Z ,11 E )‐hexadeca‐9,1‐dienal and (11 Z )‐hexadec‐11‐enal, in approximately 10 : 1 ratio. Various doses of identified compounds were investigated in wind tunnel experiments individually and in a 10 : 1 ratio. At all tested doses (9 Z ,11 E )‐hexadeca‐9,1‐dienal alone elicited upwind orientation and source location only in a minority of tested males. An admixture of (11 Z )‐hex‐11‐enal enhanced the attractiveness of (9 Z ,11 E )‐hexadeca‐9,11‐dienal significantly. This two‐component blend (100 pg) was as attractive as natural pheromone extracted from three female pheromone glands. The data suggest that (11 Z )‐hexadec‐11‐enal is a part of the D. saccharalis sex pheromone.
