“…Though the interpulse interval can vary widely among different species of the genus Drosophila, generally this is not observed when populations of the same species are analyzed (Costa et al, 2000;Ritchie et al, 1994). The three analyzed populations of D. coroica had significant differences only in the intrapulse interval, with no differences in the interpulse interval and intrapulse frequency.…”

The aim of this work was to characterize the male courtship song pattern of various species of the fasciola subgroup and to determine the level of variation both within and among species. The parameters analyzed were intrapulse interval (PI), interpulse interval (IPI), and intrapulse frequency (IF). Six different species were analyzed: D. coroica (three populations), D. ellisoni, D. fascioloides, D. moju, D. onca, and D. rosinae (one population each). There were significant differences among the six species for these three courtship song parameters. The IPI was the most variable parameter among these species, suggesting that this parameter is important for female discrimination. Four different hypotheses could explain this variation: 1. different selection pressures with absence of flow gene; 2. intraspecific sexual selection; 3. sympatric effects on song evolution; and 4. genetic drift. The PI was the only parameter that was significantly different among the three population of D. coroica. Low variability among populations within the same species was already observed for other subgroups and could be explained by the following hypotheses: strong selection acting on the song parameters, gene flow, or recent colonization from a common source. Additional studies of the courtship song of other species of the fasciola subgroup, as well as for other subgroups of the repleta group, and studies, using molecular makers, that focus on the genetic basis of the differences among these species in courtship song would allow us to evaluate the association of courtship song and sexual isolation in these species, and would also help us to understand the evolution of these behavioural differences.Key words: drosophila, fasciola subgroup, courtship song, evolution, behavior. 3. efeito de simpatria; e 4. deriva genética. As análises realizadas entre as 3 populações da espécie D. coroica mostraram diferenças estatísticas somente em relação ao PI. Essa baixa variabilidade entre populações de uma mesma espécie também já foi encontrada em outros subgrupos e pode ser explicada pelas seguintes hipóteses: forte seleção sobre os parâmetros sonoros, ocorrência de fluxo gênico entre as populações ou colonizações recentes a partir de um ancestral comum. Estudos da corte sonora de outras espécies do subgrupo fasciola e mesmo de espécies de outros subgrupos do grupo repleta, e também estudos relacionados à base genética das diferenças sonoras entre as espécies, utilizando marcadores moleculares, ajudariam a avaliar a relação dos parâmetros sonoros com o processo de isolamento sexual e também a entender a evolução dessas diferenças comportamentais.

This study presents a literature review of Drosophilidae (Diptera) species occurrence in Brazil. 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.
