Sound production during agonistic behavior of male Drosophila melanogaster

摘要: Male Drosophila fruitflies acquire and defend territories in order to attract females for reproduction. Both, male-directed agonistic behavior female-directed courtship consist of series recurrent stereotypical components. Various studies demonstrated the importance species-specific sound patterns generated by wing vibration as being critical male success. In this study we analyzed signals during interactions melanogaster. contrast acoustic that sine pulse are one extended wing, lack sine-like components generally produced simultaneous movements both wings. Though intra-pulse oscillation frequencies (carrier frequency) identical, inter-pulse intervals twice long more variable aggression than songs, where their precise temporal pattern serves species recognition. Acoustic si...
