Abstract: | Volatile compounds from Drosophila melanogaster males and females dramatically affect male courtship behaviour. These substances, which have been extracted from flies of different ages and genotypes, have been analysed by gas chromatography (GC) and in behavioural assays. Extracts from virgin females and males have different gas chromatographic profiles, which may reflect the fact that extract from virgin females stimulates high levels of courtship between males over short distances, while extract from mature wild-type males does not affect sexual behaviour. However, volatile compounds from very young males or males expressing the fruitless (fru) mutation do stimulate courtship between males, and chromatographic profiles of young male and fru male extracts differ from the GC profile of extracts from mature wild-type males. |
