The subgroup of Drosophila nasuta consists of 14 species, subspecies and taxa. It has a wide distribution in area of Indo-Pacific Ocean. The courtship song of species in nasuta subgroup is recorded for the first time in the paper. Some parameters of temporal pattern of pulse song were measured: the inter burst interval (IBI), the interpulse interval (IPI), the length of a pulse train (PTL), the number of pulses in a train (PN), the length of a pulse (PL) and the length of a cycle (CL). Computer analysis techniques were used to make spectral analysis of sine song. A three-dimensional power spectra of the sound was made. In this subgroup, the male of D. pulauna and Taxon-F didn't produce any sound signals during courtship, suggesting that the visual stimuli play an important role in mating process. By analysing the courtship sound signals of other species, subspecies and taxa, the sounds produced by courting male could be described as pulse song or as sine song. By studying the sounds of intra- or interspecific F1 hybrids we have found that the parameters of the temporal pattern of pulse song, for example, the mean value of IPI is controlled by X-linked and autosomal polygene and the sine song frequency is predisposed to the maternity. The phylogenetic tree of the subgroup is constructed based on the temporal pattern of the pulse sounds in different species, subspecies and taxa. The relationship within the members of the Drosophila nasuta subgroup is discussed.
纳氏果蝇亚群由14个物种、亚种和分类单元组成。它在印度-太平洋地区分布广泛。本文首次记录了纳氏果蝇亚群中各物种的求偶歌。测量了脉冲歌时间模式的一些参数：爆发间期（IBI）、脉冲间期（IPI）、脉冲串长度（PTL）、一串脉冲中的脉冲数（PN）、一个脉冲的长度（PL）和一个周期的长度（CL）。使用计算机分析技术对正弦歌进行频谱分析，制作了声音的三维功率谱。在这个亚群中，普拉纳果蝇和分类单元F的雄性在求偶期间不产生任何声音信号，这表明视觉刺激在交配过程中起重要作用。通过分析其他物种、亚种和分类单元的求偶声音信号，求偶雄性产生的声音可描述为脉冲歌或正弦歌。通过研究种内或种间F1杂种的声音，我们发现脉冲歌时间模式的参数，例如IPI的平均值受X连锁和常染色体多基因控制，而正弦歌频率则倾向于母本。基于不同物种、亚种和分类单元的脉冲声音时间模式构建了该亚群的系统发育树，并讨论了纳氏果蝇亚群成员之间的关系。
