Courtship songs have undergone a spectacular diversification in the Drosophila buzzatii cluster. Accordingly, it has been suggested that sexual selection has played a significant role in promoting rapid diversification, reproductive isolation and speciation. However, there is no direct evidence (i.e., song playback experiments with wingless males) supporting this tenet. Moreover, several studies have showed that the courtship song in the genus Drosophila is not always used in female mate choice decisions, nor plays the same role when it is taken into account. In this vein, we use an approach that combines manipulative and playback experiments to explore the importance and the role of courtship song in female mate choice in four species of the D. buzzatii cluster and one species of the closely related D. martensis cluster for outgroup comparison. We also investigate the importance of courtship song in sexual isolation in sympatry between the only semi-cosmopolitan species, D. buzzatii, and the other species of the D. buzzatii cluster. Our study revealed that the courtship song is used by females of the D. buzzatii cluster as a criterion for male acceptance or influences the speed with which males are chosen. In contrast, we showed that this characteristic is not shared by D. venezolana, the representative species of the D. martensis cluster. We also found that the studied species of the D. buzzatii cluster differ in the role that conspecific and heterospecific songs have in female mate choice and in sexual isolation. Our findings support the hypothesis that divergence in female preferences for courtship songs has played a significant role in promoting rapid diversification and reproductive isolation in the D. buzzatii cluster. However, evidence from D. venezolana suggests that the use of the courtship song in female mate choice is not a conserved feature in the D. buzzatii complex.

“…In this group, IPI is relatively constant and not important to mate recognition whereas characters of the pulse trains, such as PN and PTL, as well as pulse structure traits, such as CPP and IPF, are variable and important (Aspi and Hoikkala, 1995;Lumme, 1984, 1987;Hoikkala et al, 1998;Liimatainen et al, 1992). Although IPI is not important to mate recognition, it does play a role species recognition (Saarikettu et al, 2005).…”

Mutations and Natural Genetic Variation in the Courtship Song of Drosophila

All Drosophila species have a courtship repertoire by which a male stimulates a female to mate with him. In many species, males vibrate their wings to produce courtship song, an element of courtship that plays an important role in female choice. Each species has a unique courtship song, with the major differences among species songs being in timing and/or structure. Analysis of genetic mutations has revealed 17 genes that affect courtship song in Drosophila melanogaster. Most of the genes were first identified as affecting another trait and were subsequently shown to affect song. Quantitative genetic studies have demonstrated a polygenetic additive genetic architecture for many song traits. Few candidate genes, identified through the classical genetic approach, coincide with the regions implicated as affecting natural variation. With many new tools in genetic analysis and the multiple Drosophila genome projects currently underway, the ability to relate mutational and quantitative analyses will improve.

“…Among many of these ablation results exhibited in the literature, it is important for the present discussion to mention those revealing that one of the main structures of the brain, which is named central complex, coordinates behavior programs in D. melanogaster, including the program of the sound produced by males, which is an important component of the courtship [40,41]. It is known that this sound is species-specific and its changes difficult or even block the male acceptance by female, thus acting as a mechanism of sexual isolation [42]. These findings incite the idea of association between brain damage due to HU action and the performance in mating.…”

Abstract:The clinical efficacy of oral hydroxyurea (HU) in the treatment of the sickle cell disease (SCD) is already proven. However, side-effects on reproduction and development still cause concerns, mainly in long term treatments. We used Drosophila melanogaster as a model organism in the study of this subject. This species has been considered favorable for studying human diseases and responses to drugs because both organisms share more than 50% of the genes for disease and exhibit a very similar drug metabolism. In addition, D. melanogaster allows laboratory approaches that are not possible in humans. We analyzed the impact of the concentrations HU 0.1 and HU 0.25 on productivity, oviposition rate, emergence period duration, mortality and development time from egg to adult. HU affected all these traits, showing dose dependence. The frequency of mating, and duration of premating and mating times of flies were also analyzed in treatments with HU 0.25. Considering all the traits, the treatments decreased the productivity, oviposition rate and frequency of mating, and increased the emergence period duration, mortality rate from egg to adult and development time. The premating and mating times duration were affected in a more complex way. On the basis of the knowledge that HU affects DNA synthesis and repair, and other data available in the literature, we raised hypotheses to explain the present observations. The results and hypotheses suggested new approaches for further studies of particular and important aspects. In general, this study reinforces the validity of the concern with HU side-effects.Keywords: Emergence period duration, impaired effect of hydroxyurea, mortality from egg to adult, number of progeny, oviposition rate.
