Ocorrência de Selenaspidus articulatus (Morgan, 1889) (Hemiptera-Sternorrhyncha: Diaspididae) no Estado do Amapá.

A citricultura é uma das atividades agrícolas mais importantes em nível mundial, ocupando destacado lugar na economia de diversos países. No entanto, a cultura de citros é atacada por um grande número de pragas, cuja intensidade de infestação está na dependência das condições climáticas e do manejo dispensado ao cultivo. Para combater as pragas, muitos agricultores utilizam agrotóxicos indiscriminadamente, que provocam efeitos adversos à fauna benéfica existente nos pomares, podendo propiciar um aumento na população das pragas secundárias, em decorrência da morte de seus inimigos naturais.bitstream/item/97386/1/CPAF-AP-2003-Ocorrencia-selenaspidus.pd

Textile sustainability: reuse of clean waste from the textile and apparel industry

Today societies are already experiencing changes in their production systems and even consumption in order to guarantee the survival and well-being of future generations. This fact emerges from the need to adopt a more sustainable posture in both people's daily lives and productive systems. Within this context, textile sustainability emerges as the object of study of this work whose aim is to analyse which sustainability dimensions are being prioritized by the clean waste management systems of the textile and garment industries. This article aims to analyse solutions that are being proposed by sustainable creative business models in the reuse of discarded fabrics by the textile industry. Search also through a qualitative research by a case study (the Reuse Fabric Bank) understand the benefits generated by the re-use in environmental, economic, social and ways to add value.This work is supported by FEDER funds through the Competitivity Factors Operational Programme - COMPETE and by national funds through FCT - Foundation for Science and Technology within the scope of the project POCI-01-0145-FEDER-007136.info:eu-repo/semantics/publishedVersio

Viticultura em alerta.

Estudo mostra os riscos de introdução da Doença-de-Pierce no Brasil, através da importação de material propagativo proveniente de países onde o problema está disseminado. A presença de vetores autóctones, capazes de dispersar o patógeno nos vinhedos brasileiros, agrava a preocupação

Aquatic contamination of the Turvo Limpo river basin at the Minas Gerais state, Brazil

The aquatic contamination from the discharge of untreated or inadequately treated municipal sewage, as well as from husbandry, agriculture, and the disposal of municipal garbage, metallic scraps and civil architecture residues in the neighborhood of the Turvo Limpo River basin was evaluated. The water-courses examined were the São Bartolomeu Stream, Turvo Sujo River, and Turvo Limpo River, located in the Minas Gerais State, Brazil. Water samples were collected at the river-side in the dry season (July, August, and September 2005) and analyzed for evaluation of pollutant inputs. The pH, dissolved oxygen (DO), biochemical oxygen demand (BOD), total phosphate, total ammonia nitrogen (NH3 + NH4+), nitrate and metal concentrations (Al, Ca, Cr, Cu, Fe, Mg, Ni, Pb, and Zn) in water samples were determined. The concentrations of these metals in the suspended solids were also determined. The suspended solids showed high concentrations of Zn (15,350 mg kg-1) and Pb (3,590 mg kg-1), while the stream water was enhanced with Al (1,480 µg L-1). The pH and the concentrations of BOD, total phosphate and total ammonia nitrogen in the water-courses were far from those established by the Brazilian Environmental Standards for Class 2 water. In all examined sites there was an increase in the nitrate concentration compared with that of a spring (site 1). The nitrate concentrations were below those of the total ammonia nitrogen, indicating that the nitrogen in the water-courses was mainly originated from recent sewage discharges, since did not occurred larger mineralization with the formation of nitrate ions
