Abstract

The structure of the sex pheromone produced by the male sandfly Lutzomyia longipalpis, from the Lapinha Cave (Minas Gerais State) region of Brazil, previously proposed tentatively as the novel homosesquiterpene 9-methylgermacrene-B, is confirmed and the absolute stereochemistry defined as S by comparing physical and biological properties of the synthetic enantiomers with the natural product.
