Bombykal, a Sex Pheromone of the Sphinx Moth Manduca Sexta

Abstract

The first sex pheromone of a Sphinx moth has been isolated from Manduca sexta (Lepidoptera: Sphingidae) with the aid of an electroantennogram assay. It is attractive to males in a field test where its activity might be augmented by a second component in female extracts. Chemical tests and chromatographic properties identify the pheromone as a C16-aldehyde with a pair of conjugated double bonds. (E, Z)-10, 12-hexadecadienal, (“bombykal”) was identical with the natural product. The comparison includes chromatography on three different capillary columns and determination of specific activities in the electroantennogram test. © 1979, Walter de Gruyter. All rights reserved.
