La bella molinera

Aquest treball vol ser una aproximació a l’obra Die schöne Müllerin, D795, un cicle de vint cançons per a veu i piano, que Franz Schubert va compondre l’any 1823. L’obra es basa en un conjunt de poemes que havia escrit poc abans Wilhelm Müller, i que expliquen la història del desengany amorós d’un jove aprenent de moliner. La bella molinera presenta un ventall infinit de colors, emocions, paisatges... Va des de l’alegria més eufòrica fins a la desesperança més fonda, passant per moments d’ironia, de somnis i de sorpreses. Tot això és analitzat en el treball, número per número, tan en l’aspecte literari com en el musical, i en la seva interrelació.

As abelhas eussociais (Hymenoptera, Apidae) visitantes florais em um ecossistema de dunas continentais no médio Rio São Francisco, Bahia, Brasil

Highly eusocial bees (Hymenoptera, Apidae) flower visitors in a continental sand dune ecosystem from the medium São Francisco River, Bahia, Brazil. A community of highly eusocial bees in sand dunes, covered with caatinga vegetation, in the medium São Francisco River, Bahia (10º47' 37"S and 42º49' 25"W) was studied. The local climate is semi arid and hot, with mean temperature of 25.7 ºC and annual precipitation of 653.8 mm. Censuses took place every two months, from February to December of 2000. The bees were sampled on flowers with entomological nets, from 6:00 a.m. to 5:00 p.m. A total of 2,147 individuals of eight species of Apinae were found, of which Apis mellifera Linnaeus (40.2%), Trigona spinipes (Fabricius) (28.7%) and Frieseomelitta silvestri languida Moure (14.7%) were the predominant species. The diversity was H' = 1.53 and the evenness E' = 0.73. The bees were active during the whole year, but there was a significant variation in the monthly abundance of individuals (c2= 799.55; df= 35; p<0.0001). The daily activity was greater between 6:00 a.m. and 8:00 a.m. The low bee diversity observed is a consequence of the low richness of botanical species and of the small amount of sites for the bees' nests. The community of highly eusocial bees from the dunes presents organization patterns similar to those observed in other caatinga areas, albeit with some particularities.

First record of Anastrepha parishi Stone (Diptera, Tephritidae) and its host in Brazil

Anastrepha parishi Stone, 1942 was reared in fruits of Oenocarpus bacaba Martius, 1823 (Arecaceae) collected in Pracuúba, State of Amapá. This is the first record of an Anastrepha species in a native species of Arecaceae.

Vector competence of Culex quinquefasciatus Say, 1823 exposed to different densities of microfilariae of Dirofilaria immitis (Leidy, 1856)

The metropolitan region of Recife, Brazil is endemic for Dirofilaria immitis and has an environment favorable to the development of Culex quinquefasciatus. The goal of this study was to evaluate the vector competence of the Cx. quinquefasciatus RECIFE population for D. immitis transmission. A total of 2,104 females of Cx. quinquefasciatus RECIFE population were exposed to different densities of D. immitis microfilariae blood meals, ranging from 1,820 to 2,900 mf/ml of blood, in a natural membrane apparatus. The results showed a variation between 92.3% and 98.8% of females fed. The exposure of the Cx. quinquefasciatus RECIFE population to different densities of microfilariae did not influence the mortality of the mosquitoes. Infective larvae from D. immitis were observed in the Malpighian tubules beginning on the 12th day, whereas larvae were observed in the head and proboscis beginning on the 13th day following infection. The vector efficiency index (VEI) presented by the mosquitoes ranged from 7.8 to 56.5. The data demonstrates that the Cx. quinquefasciatus RECIFE population has great potential for the transmission of D. immitis, as it allowed the development of the filarid until the infectious stage at the different densities of microfilariae to which it was exposed.

As mornas de Francisco Xavier da Cruz (B. Léza) como referência para a reconstituição da história psicossocial e cultural de Cabo Verde

Os músicos integram o grupo dos actores sociais cujas obras não deixam de constituir contributos valiosos para a reconstituição históricocultural das sociedades a que pertencem. Francisco Xavier, B. Léza, é um desses actores sociais que, em termos da construção musical de Cabo Verde, carece de uma investigação aprofundada de modo a podermos identificar, a partir da referida produção, elementos para a reconstituição da nossa historicidade sócio-cultural. Com efeito, várias são as composições musicais de B. Léza que fazem um retrato psicossocial de S. Vicente e de Cabo Verde, o que nos faz pensar a obra musical desse autor como parte das fontes orais e escritas da reconstituição histórica de Cabo Verde, quer na sua abordagem local quer na sua abordagem geral, nomeadamente nas dimensões psicossociais e culturais Ora, é nosso entender que reconstituir a história cabo-verdiana com base na pluralidade das suas fontes é uma forma de fincar os pés na terra – projecto caro aos Claridosos. Assim, com a nossa participação neste encontro tentaremos abordar a contribuição musical de B. Léza como fonte e referência da reconstituição da história sóciocultural cabo-verdiana, desde que cruzada com outras fontes, nomeadamente com a escrita. Por outro lado, pensamos que este tipo de investigação sobre a obra de B. Léza é uma das melhores formas de homenagear esta figura de proa da cultura cabo-verdiana.
