Moreover, we compare distribution, abiotic and biotic niches between both species and perform ecological simulations in order to assess the potential influence played by ecology versus geography in the divergence of the target species, which was also dated with the use of a nuclear marker. The aedeagus and wing morphometry patterns were underpinned by molecular evidence, as obtained for the mitochondrial COI and COII partitions. In fact, reciprocal monophyly and a barcoding gap were detected, in spite of the strict external resemblance, the strong abiotic and biotic niche overlaps and the frequent sympatry and syntopy observed between both species. Thus, we hypothesize here a mechanism of geographic speciation associated with a pattern of niche conservatism to the pair of Zygothrica species diver...

Drosophila suzukii have a rapid expansion worldwide; occurrences were recorded in North America and Europe in 2008, and South America in 2013. Due to this rapid expansion, we modeled the potential distribution of this species using the Maximum Entropy Modeling (MaxEnt) algorithm and the Genetic Algorithm for Ruleset Production (GARP) using 407 sites with known occurrences worldwide and 11 predictor variables. After 1000 replicates, the value of the average area under the curve (AUC) of the model predictions with 1000 replicates was 0.97 for MaxEnt and 0.87 for GARP, indicating that both models had optimal performances. The environmental variables that most influenced the prediction of the MaxEnt model were the annual mean temperature, the maximum temperature of the warmest month, the mean temperatur...

In the present study five species are redescribed: R. angustifrons Malogolowkin; R. lopesi Malogolowkin; R. matogrossensis Malogolowkin; R. nigrescens Malogolowkin and Rhinoleucophenga personata Malogolowkin. R. capixabensis Culik & Ventura is proposed as a new junior synonymy of R. lopesi. Other species, R. jacareacanga sp. nov., is described from the specimens deposited at CEIOC/Fiocruz. The description of new species and review of some former descriptions of Rhinoleucophenga is indispensable since the distribution records of some species are doubtful.

The aims of the present study were to describe the diversity of mycophagous Drosophilidae and to investigate its colonization of fungal hosts in a forest of southern Brazil. From 120 fungal samples (patches of mushrooms) of 17 Basidiomycetes genera, flies were recorded emerging from 70 samples and collected in adult stages of 25 fungal samples, for a total of 4897 drosophilids belonging to 31 species and 5 genera. Drosophila Fallén was the most species-rich genus, whereas Hirtodrosophila Duda was the dominant genus. Studies performed in the Holarctic region indicate that mycophagous drosophilid have generalist habits; however, our results showed that most drosophilids use fewer than two fungal hosts, and most species of Hirtodrosophila and Leu...

Animal exposure to this herbicide can lead to adverse effects, such as endocrine disruption, oxidative stress and behavioural disorders. Drosophilids have been utilized previously as an effective tool in toxicological tests. In the present study, the effects of a glyphosate-based herbicide (Roundup [Original]) were investigated regarding oxidative stress, the antioxidant defence system and acetylcholinesterase (AChE) activity in Drosophila melanogaster. Flies (of both genders) that were 1 to 3days old were exposed to different glyphosate concentrations (0.0mg/L=control, 1.0mg/L, 2.0mg/L, 5.0mg/L and 10.0mg/L) in the diet for 24h and 96h. After the exposure periods, reactive oxygen species (ROS) levels, antioxidant capacity against peroxyl radicals (ACAP) and lipid peroxidation (LPO) levels were quantified. In addition, the mRNA expression of antioxidant genes (i.e., keap1, sod, sod2, cat, irc, gclc,...

The number of species recorded is 304, with Drosophila being the genus with the greatest number of species, followed by Zygothrica, Hirtodrosophila and Diathoneura, which belong to the Drosophilinae subfamily. Drosophila was shown to be the most investigated taxon in the family, with the best resolved species distribution. The low number of records of species from other genera indicates the paucity of studies specifically designed to investigate these species. Records of species for some regions of the country like the north and northeast, as well as for some biomes like Caatinga, Pantanal and the Pampas, are likewise rare. Apart from the banana bait, different collection methods may be necessary, like the collection at other oviposition resources, the use of baits other than fermenting fruit, and the adoption of sampling approaches that do not use baits.

O estado de Santa Catarina contava apenas com algumas coletas esporádicas de pesquisadores de outros estados até o final da década de 1980 (ver Sene et al., 1980). Desde então muitos estudos têm sido realizados no intuito de analisar a diversidade e a variação temporal dos drosofilídeos em diversos ecossistemas encontrados neste estado. A mata atlântica, o manguezal e o ambiente urbano já foram minimamente explorados, e este é o primeiro trabalho que trata de drosofilídeos em restingas do sul do Brasil. Até então, o único estudo realizado em restingas era o de Bizzo e Sene (1982), que registrou 25 espécies de Drosophila em Peruíbe, São Paulo. Este estudo objetivou analisar a riqueza e a distribuição temporal de uma assembléia de drosofilídeos em uma área de mata de restinga na praia da Joaquina, ilha de Santa Catari...
