在交配前的求爱过程中，雄性果蝇通常会在爬上雌性果蝇之前产生翅膀振动来产生物种特异性的歌曲。有三个种在亚麻分支的montium种亚组已被发现产生种特异性正弦歌曲后安装和交配。本文通过对29种鸟的求偶行为的录像和鸣唱记录进行了研究和分析，并测量了翅振动的持续时间。我们描述了一个巨大的求偶行为的多样性montium子群。其求偶方式可分为4种类型：1）P/C型，即既有交配前求偶又有交配求偶，如D. parvula和D. nikananu，2）P-/C型，具有零星前脉冲求爱和主要交配求爱的物种，例如D. auraria和D. triauraria。3)C型，仅具交配求偶的种类，如D. tani和D. pectinifera，4）C-型，交配期很短，如D. rufa和D.朝日内根据线粒体COI、COII和细胞核Adh基因序列构建的系统发育树表明，在最底层种D.小的montium子群中的两个分支中的每一个都包含四种类型的求偶行为。C型存在于每个子分支中。这些结果表明，求偶行为最初涉及precopulatory和交配求偶，但随后precopulatory求偶已逐渐失去montium亚组。我们提出的原因，precopulatory行为可能会丢失的montium亚组。
During precopulatory courtship, male Drosophila typically produce wing vibration to generate species-specific songs before mounting females. Three species in the lini clade of the montium species subgroup have been found to produce species-specific sine song only after mounting and during copulation. Here we investigated and analyzed the courtship behavior of 29 species in the montium subgroup from video and song recordings and measured the duration of wing vibration. We describe a great diversity of courtship behavior in the montium subgroup. The courtship patterns can be categorized into four types in the montium subgroup: 1) type P/C, species with both precopulatory and copulatory courtship, such as D. parvula and D. nikananu, 2) type P-/C, species with sporadic precopulatory and mainly copulatory courtship, such as D. auraria and D. triauraria. 3) type C, species with only copulatory courtship, such as D. tani and D. pectinifera, 4) type C-, species with only very brief copulatory courtship, such as D. rufa and D. asahinai. According to a phylogenetic tree based on sequences of mitochondrial COI and COII, and the nuclear Adh, both precopulatory courtship and copulatory courtship were present in the most basal species D. parvula. Each of two branches in the montium subgroup contains four types of courtship behavior. Type C is present in each sub-branch. These results suggest that the courtship behavior initially involved both precopulatory and copulatory courtship, but that subsequently precopulatory courtship has gradually been lost in the montium subgroup. We suggest reasons why precopulatory behavior might come to be lost in the montium subgroup.
