11-cis-Vaccenyl acetate (cVA) is a volatile chemical compound that acts as a pheromone in Drosophila and at least one species of longhorn beetle. It is the acetate ester of vaccenyl alcohol. The odorant receptor subunit Or67d was shown to be necessary for detection of cVA. Males that are mutant for Or67d start courting other males whereas females that lack Or67d become less receptive towards males courting them. The sensory neurons expressing Or67d send projections to the glomerulus DA1.
