Drosophila melanogaster produce different communication sounds during interactions with conspecifics by vibrating their wings. Males sing a pre-copulatory courtship song with pulse and sine elements. Females sing a structurally different song during copulation. Both sexes also produce a third type of sound pulses during agonistic interactions, i.e. during sexual rejection and inter-male aggression. It is well established that male courtship song increases female receptivity to mating. Female copulation song depends on male inseminate composition and might influence the transfer of the latter. The behavioural effect and function of agonistic sounds are not yet fully understood. Male courtship song production relies on sex specific neurons. As a precisely quantifiable and very specific element of courtship with defined motor parameters, it is an ideal model system for behavioural circuit neuroscience and has provided basic insight to how the nervous system generates, modulates and patterns adaptive behaviour. Central brain networks integrate multimodal sensory information and flexibly control the initiation and maintenance of singing. The circuits generating the species-specific song pattern and shaping motor control of the wing are mainly located in the ventral nerve cord. First studies have started to address how other Drosophila species with divergent sound producing behaviour differ on the level of neuronal circuits from D. melanogaster. In the future, advances in connectomics are expected to greatly facilitate neuronal circuit analysis in general and allow for a comprehensive synthesis of described circuit motifs for different aspects of sound production and its coordination in behavioural context.
