Sucrose esters are biodegradable, non pollutant and safe for health; moreover, they have shown great potential in the pest control. We tested a crude mix of sucrose esters on the survivorship and oviposition of Calacarus heveae Feres (Acari: Eriophyidae) females, an important rubber tree pest mite. The females were collected from rubber leaflets of the GT 1 and RRIM 600 clones. The mites were kept on stock arenas placed in rearing chamber at 28 + 0,1°C, 80 + 10% of relative humidity and 12h of light phase about two weeks before the assays. After this period, the mites were transferred to assay arenas made with leaflets from the same clone of stock arenas. The survivorship of females sprayed with sucrose esters in the concentrations of 1, 2, 3 and 4 g/L and their oviposition effect with 0.5 and 1 g/L were analyzed. The mites sprayed with 4 g/L had about 80% of mortality, while those with 1 g/L around 60%. All mites that died in the treatments with sucrose ester became dark with wrinkled tegument and decreased their body volume, suggesting dehydration. We also observed the efficacy of 1 g/L concentration to decrease the female oviposition in about 50%, in the third day after spraying. No differences were observed in the mortality and oviposition between females kept on both clones.

Partindo da conceituação de termos caros à teoria e à crítica da poesia lírica, perfaço um breve estudo da poesia em prosa do simbolista brasileiro Cruz e Sousa (1861-1898), consubstanciada nos livros Missal (1893) e Evocações (1898). Procurei evidenciar o processo de composição das duas obras e as diferenças entre ambas, frisando inclusive o modo pelo qual o poeta configura suas imagens poéticas. Assim, articulando os conceitos de Imagem e Epifania – utilizados pelo poeta de maneira moderna e original –, busquei ressaltar sua importância no processo construtivo de Cruz e Sousa, salientando, por fim, o lugar de destaque que o poeta ocupa nos quadros da poesia brasileira.

Direct descendant of the music of the Black Atlantic, hip hop became the spokesman of excluded minorities, for example setting up of the reunification that is geographically separated through communication. The hip hop appropriated new forms of mass communication, allowing the reworking of the story through a counter-hegemonic discourse that seeks self-knowledge and appreciation of the roots of black people. The street culture is the narrative of disenfranchised youth, generating narrative of inclusion, which gave a space of enunciation periphery enabling them to intersubjective recognition. This project aims to discuss the role of hip hop as an agent conscientizing youth peripherals in order to bring to the debate the form of identity construction around the peripheral street culture since, as an intervention that acts as a symbolic system guiding cultural practices and attitudes of these young people. Methodologically, we analyzed specific bibliographical about hip hop and literature originating from the periphery itself. Selected discography of some rap groups. They are Racionais Mc's, 509-E and DJ Hum and Thaíde that constitute the vanguard of hip hop in Brazil. We use music from rapper Emicida this while some contemporary exponents of rap, with national and international. State of São Paulo in order to demonstrate that there is similarity between the questions proposed by the hip hop and the interior of the capital, the group selected Survey. We have used also press material, raising the issue in research on the internet, periodicals include the Rolling Stones and Caros Amigos
