Abstract: | Three compounds have been identified as sex pheromone components produced by female fall webworm moths,Hyphantria cunea (Drury). These compounds 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). The ratio of these compounds was approximately 5613, respectively, in female tip extracts prepared from U.S.S.R, insects and approximately 1821, respectively, in extracts from U.S. insects. The ratio in female effluvia trapped from U.S. insects was 1627, respectively. Compound III plus either I or II is effective in eliciting upwind flight in a wind tunnel. Compounds I, II, and III are also components of the sex pheromone system of the saltmarsh caterpillar moth,Estigmene acrea (Drury).Lepidoptera: Arctiidae.Part of this work was carried out under the sponsorship of the U.S.A.-U.S.S.R. Scientific Exchange Program and the U.S.S.R. Ministry of Agriculture. It was also supported in part by National Science Foundation grant PCM78-13241. These results were first disclosed at the EUCHEM Conference on Chemistry of Insects, held at Borgholm, Sweden, on August 13–17, 1979. We sadly note the passing away of our distinguished colleague and friend, Dr. A.S. Hill. |
