The invasive spotted-wing Drosophila (Diptera, Drosophilidae) has been found in the city of São Paulo (Brazil). Drosophila suzukii (Matsumura, 1931), the cherry fly or spotted-wing Drosophila, a pest species from the Oriental and southeastern Palaearctic regions belonging to the melanogaster group, invaded the Nearctic and western countries of the Palaearctic regions late last decade (2008) and, more recently (2013), the southern Brazilian states of Rio Grande do Sul and Santa Catarina. Early in 2014 it was reared from blueberries produced in São Joaquim, state of Santa Catarina, that were bought at a São Paulo city grocery store. Despite being a cold-adapted species, after having arrived to the southeastern state of São Paulo, this invasive fly will probably expand its territory to other Brazilian states and South American countries through trade of cultivated soft skin small fruits, such as blueberries and strawberries, as well as naturally through the use of small wild fruits as breeding sites.

Diphenylhydantoin effects in Balb C mouse bone marrow cells: cytogenetic aspects

O efeito do anticonvulsivo difinilhidantoína (DPH) foi analisado em cromossomos de células de medula óssea de camundongos Balb C. Foi observado um aumento na freqüência de células aneuplóides em animais submetidos a doses teratogênicas da droga. Esse efeito näo foi encontrado após o tratamento crônico com dose terapêutica de DPH. O DPH näo teve efeito clastogênico nos esquemas de tratamento utilizados
