ABSTRACT Among several factors that impact the bean culture productivity there are pest insects, which affect the plant since seeding until postharvest, causing loss in the culture yield. The fall armyworm (Spodoptera frugiperda) stands out among the main pests of common bean (Phaseolus vulgaris). The aim of this work was to evaluate the effectiveness of insecticides of the neonicotinoid group in the control of the fall armyworm in the bean crop, comparing dinotefuran, acetamiprid, thiamethoxam and imidacloprid performance. Experimental design was composed of blocks entirely randomized, with 9 treatments and 10 replicates. Three caterpillars, at the stage of second instar, were used in each experiment, focusing on the ingestion of leaves containing the treatments. Evaluations were realized in the intervals of 1, 3, 6 and 8 days after every application, counting the number of caterpillars alive in the Petri’s dish, attributing visual notes on bean leaves, according to the foliar area affected (consumed). The dinotefuran treatment with the highest dose presented superior efficiency at 80% in the first evaluation. The thiamethoxam treatment with the lowest dose, in the latest analyses, showed efficient superior at 90%. The major doses of all treatments presented efficiency higher than 80% in the last evaluations, being efficient in the S. frugiperda control.

RESUMO O bagaço de cana-de-açúcar é um resíduo gerado da indústria sucroalcooleira, rico em componentes de materiais lignocelulósicos, como a celulose e hemicelulose. Estes podem ser empregados como matéria-prima no segmento de papel e celulose, porém pouco aplicados no ramo papeleiro pela disponibilidade das fontes tradicionais que são o Eucalyptus e Pinus. O objetivo desse trabalho foi comparar as propriedades físicas e mecânicas dos papéis obtidos a partir da celulose extraída da cana-de-açúcar, Eucalyptus e Pinus pelo método Kraft. Foram utilizadas quatro amostras de papéis: celulose obtida 100% de fibra de cana-de-açúcar (I), celulose obtida 100% de fibra de Eucalyptus (II), 75% celulose de Eucalyptus + 25% celulose de Pinus (III) e 75% celulose de bagaço de cana-de-açúcar + 25% de celulose de Pinus (IV). Foram realizados testes físicos e mecânicos de acordo com as metodologias que regulamentam o setor papeleiro. Os resultados indicam que o papel obtido a partir da celulose da cana-de-açúcar possui características físicas e mecânicas semelhantes ao papel tradicional produzido com Eucalyptus. Características particulares como boa resistência ao rasgo e tração, maior porosidade e umidade podem ser ajustadas para adequar o papel dessa fonte ao seu uso apropriado. De modo geral, a celulose de cana-de-açúcar demonstra-se como uma opção frente ao uso do Eucalyptus e Pinus na obtenção de papéis de qualidade sustentável, tornando-se uma alternativa para a utilização de um resíduo agrícola.

ABSTRACT Sugarcane bagasse, a waste material generated by the sugar-alcohol industry, is rich in lignocellulosic components such as cellulose and hemicellulose. The bagasse can be employed as a raw material in the pulp and paper industry, but is currently rarely used for this purpose, due to the availability of traditional sources such as Eucalyptus and Pinus. The objective of this work was to compare the physical and mechanical properties of papers produced using the cellulose extracted from sugarcane, Eucalyptus, and Pinus by the Kraft method. Four paper samples were produced using cellulose obtained from the following fiber sources: (I) 100% sugarcane bagasse; (II) 100% Eucalyptus; (III) 75% Eucalyptus + 25% Pinus; (IV) 75% sugarcane bagasse + 25% Pinus. Physical and mechanical tests were performed based on regulatory methodologies of the paper industry. The results indicated that the physical and mechanical characteristics of the paper produced from the sugarcane cellulose were similar to those of the traditional paper produced using Eucalyptus. Particular features such as good tearing resistance and tensile strength, as well as increased porosity and moisture, could be adjusted according to the intended use of the paper. Therefore, sugarcane bagasse can be considered a sustainable alternative to Eucalyptus and Pinus for the production of high quality paper, adding value to this agricultural residue.

Urban population around the globe is direct exposed to the pollution caused by several sources (vehicles, industries, smokes etc.) and primary pollutants are divided in particulate matter and toxic gases. Current researches in populous countries indicated that exposure to pollution could affect sebum composition, stratum corneum quality and signs of skin aging. Hair and scalp are also affected by the excessive exposure to pollutants, resulting in a dull, dry and lifeless appearance. Cosmetics have been evolved conceptual and scientifically to achieve substantial effectiveness against pollution damaging on the cutaneous tissue, involving the development of innovative multipurpose active ingredients and efficacy tests, skilled to prove the protection and benefits of such personal care products. In this review, we highlighted the skin and hair/scalp damages provoked by the main environmental pollutants and the active substances used in antipollution cosmetics/personal care products with the respective mechanisms of action. Likewise, in vitro and in vivo efficacy tests were discussed concerning the antipollution claim substantiating.
