Abstract:Three compounds have been identified as components of the sex pheromone emitted by females of the saltmarsh caterpillar moth,Estigmene acrea (Drury). These are (Z,Z)-9,12-octadecadienal (I), (Z,Z,Z)-9,12,15-octadecatrienal (II), and (Z,Z)-3,6-cis-9,10-epoxyheneicosadiene (III). In female tip extract they were found in a ratio of 1ratio6ratio25, respectively, and in trapped female effluvia the ratio was 1ratio6ratio27, respectively. Combinations of III with either I or II elicited sustained upwind flight in a wind tunnel, but none of these compounds by themselves did so. There is evidence that the antennal acceptor site for III is chiral.Lepidoptera: Arctiidae.Supported in part by the Rockefeller Foundation and by National Science Foundation Grants GB-38020 and PCM 78-13241.
