“…Flies were raised under common-garden and controlleddensity conditions (40 first-instar larvae per vial), and a photoperiod regimen of 12h light: 12-h dark cycle. First, they were raised on standard Drosophila medium for four generations and then were moved one more generation to a 'semi-natural' medium prepared with fresh cladodes of the cactus Opuntia ficus indica (see Iglesias et al, 2018a for more details). This cactus species represents the more widespread host used by D. buzzatii in the study area.…”

“…The coancestry coefficient (FST) for each pair of populations were estimated by using data from eight microsatellite markers previously genotyped (Iglesias et al, 2018a) and the bayesian R package RAFM (Karhunen, 2012). Analyses were run for 10 6 generations with a 50% burn-in, resulting in 500 posterior distribution samples.…”

“…Here, we address these issues by investigating how the wing has evolved in twelve populations of the cactophilic species Drosophila buzzatii raised in commongarden conditions and using an isofemale line design. Only the males of the D. buzzatii species use wings to produce a courtship song (Iglesias & Hasson, 2017;Iglesias et al, 2018a;Iglesias, Soto, Soto, Colines, & Hasson, 2018b), and a previous study has shown a rapid divergence of courtship song parameters among these populations (Iglesias et al, 2018a). Thus, we first investigated whether the wings of males and females are evolving differently among the sampled populations.…”

“…This selection on males can cause the displacement of females from their phenotypic optimum, reducing their fitness. It is well documented that the direction and intensity of selection on courtship song have been found to differ among populations and species according to female preferences (Iglesias & Hasson, 2017;Iglesias et al, 2018a;Klappert, Mazzi, Hoikkala, & Ritchie, 2007).…”

The Drosophila wing is a structure shared by males and females with the main function of flight. However, in males, wings are also used to produce songs, or visual displays during courtship. Thus, observed changes in wing phenotype depend on the interaction between sex-specific selective pressures and the genetic and ontogenetic restrictions imposed by a common genetic architecture. Here, we investigate these issues by studying how the wing has evolved in twelve populations of Drosophila buzzatii raised in common-garden conditions and using an isofemale line design. The between-population divergence shows that sexual dimorphism is greater when sex evolves in different directions. Multivariate Qst-Fst analyses confirm that male wing shape is the target for multiple selective pressures, leading males' wings to diverge more than females' wings. While the wing blade and the wing base appear to be valid modules at the genetic (G matrix) and among-population (D matrix) levels, the reconstruction of between-population adaptive landscapes (Ω matrix) shows selection as an integrative force. Also, cross-sex covariances reduced the predicted response to selection in the direction of the extant sexual dimorphism, suggesting that selection had to be intensified in order to circumvent the limitations imposed by G. However, such intensity of selection was not able to break the modularity pattern of the wing. The results obtained here show that the evolution of D. buzzatii wing shape is the product of a complex interplay between ontogenetic constraints and conflicting sexual and natural selections.

The study of Diptera at the scene of a crime can provide essential information for the interpretation of evidence. Phylogeographic reconstruction could help differentiate haplotypes of a dipteran species in a geographical area, clarifying, for example, the details of a possible relocation of a corpse. In addition, inferring the ancestral areas of distribution helps to understand the current status of the species and its biogeographic history. One of the most important species in forensic entomology is Calliphora vicina Rovineau-Desvoidy, 1830 (Diptera: Calliphoridae). The aim of this work is to increase our knowledge of this species in the Iberian Peninsula using 464 specimens from Spain and Portugal. These samples were identified using morphological keys and by molecular methods using fragments of the cox1, 16S and ITS2 genes. The phylogeographic history of these populations was inferred from haplotype networks and the reconstruction of ancestral areas of distribution. The molecular results corroborated the morphological identifications of the samples. Phylogeographic networks showed no geographical structure, as haplotypes are shared among almost all populations. reconstruct ancestral state in phylogenies analyses showed a high rate of movement among populations, possibly related to human activity. These results suggest that this species had a very rapid and recent spatial and demographic expansion throughout the Iberian Peninsula.
