“…60 Because D. melanogaster currently seems to have a smaller Ne than D. simulans, 30,61,62 this factor could explain the apparent higher frequency of transfers in the direction of D. melanogaster. Although both species have the same population size, as suggested by recent data, 63 a small value of Ne during the beginning of speciation or a decrease in Ne during colonization by invasive species, such as D. melanogaster, D. simulans, 64 and the Zaprionus species, 34,35,65 could enhance HTs owing to proliferation of the recently introduced TE. An alternative hypothesis is that the D. simulans genome is not resilient to invasion but can resist the proliferation of TEs, as experimentally demonstrated.…”

“…The details of this colonization have been completely lost. However, the association of this drosophilid with altered environments and evidence that the recent colonization of the Americas probably occurred through the intercontinental transport of fruits ( David et al , 2006b ; Yassin et al , 2009a ; Galego and Carareto, 2010a ), it is likely that the colonization of Asia occurred in a similar way during the great navigations at the end of the Middle Ages or beginning of the Modern period (15 th century) that involved the trading of spices and other products between the East and West. There are still questions, however, regarding the dispersal of Z. indianus in the Palearctic regions through the international fruit trade.…”

Zaprionus indianus is a dipteran (Drosophilidae) with a wide distribution throughout the tropics and temperate Palearctic and Nearctic regions. There have been proposals to reclassify the genus Zaprionus as a subgenus or group of the genus Drosophila because various molecular markers have indicated a close relationship between Zaprionus species and the immigrans-Hirtodrosophila radiation within Drosophila. These markers, together with alloenzymes and quantitative traits, have been used to describe the probable scenario for the expansion of Zaprionus indianus from its center of dispersal (Africa) to regions of Asia (ancient dispersal) and the Americas (recent dispersal). The introduction of Z. indianus into Brazil was first reported in 1999 and the current consensus is that the introduced flies came from high-latitude African populations through the importation of fruit. Once in Brazil, Z. indianus spread rapidly throughout the Southeast and then to the rest of the country, in association with highway-based fruit commerce. These and other aspects of the evolutionary biology of Z. indianus are addressed in this review, including a description of a probable route for this species’ dispersal during its recent expansion.

Drosophilid species (Insecta, Diptera) in the Brazilian savanna are more symmetric in the dry season

The development of an organism is a controlled process, which can be disrupted by genetic or environmental stress. Although fluctuating asymmetry is widely used as an indicator of developmental instability, its effectiveness has been questioned due to the contradictory results produced by this technique which, at least in part, probably reflects methodological inappropriateness. Here, we investigated if wing asymmetry of drosophilids increases when they develop during the dry season in the Brazilian savanna, considered a stressful season for these insects. Using protocols designed to avoid methodological problems, we analysed the wings of Zaprionus indianus and three species of the genus Drosophila (D. mercatorum, D. simulans, and D. sturtevanti). Surprisingly, the flies were more asymmetrical in the rainy season than in the dry season, although this difference was not always significant. It is suggested that the wings of these insects are submitted to strong natural selection throughout the dry season, when the asymmetric individuals would have less chance of surviving. During the wet season, on the other hand, selective pressures would be more relaxed. Therefore, the results of this study suggest that asymmetry of the wings is not a good indicator of natural environmental stress in drosophilids. Future research should focus on selectively neutral characters.
