The study evaluated the applicability of the ESG agenda in the management practices of theMilitary Fire Brigade of Mato Grosso do Sul (CBMMS). Relationships were established between the ESG agenda and the CBMMS strategic guidelines, which serve as guidance for planning all operational and administrative activities of the corporation. A bibliographical research was carried out that collected information on the topic of sustainability and ESG principles, evaluating characteristics applicable to the management of the CBMMS. With the analysis of the Corporation's strategic level documents, alignments were made with the principles established in the theoretical framework, finally, the qualitative analysis of the data collected carried out a comparison between the corporate activities carried out in the CBMMS with the ESG principles, raising the applicability of theme in the strategic management of the Institution. It was found that good practices developed in the corporation are already interconnected with the ESG principles, making their applicability and implementation easier organically. However, there is a need for these principles to be more formalized and expressed instrategic management, as in many cases, there is a lack of coordination between isolated and disconnected actions, where the different dimensions of ESG end up being treated separately.

The present study aims to relate the micronucleus frequency in Tradescantia pallida to environmental factors and cardiorespiratory diseases to infer the effect of air pollution. The number of hospitalizations, diseases cases, frequency of micronuclei in plants, environmental variables, altitude, and vehicle traffic in cities of Mato Grosso do Sul were evaluated due to the high flow that surrounds agribusiness. The frequency of micronuclei decreased with the increase in relative humidity, while the altitude did not influence the mutagenicity or genotoxicity of the evaluated plants. The municipalities with micronucleus frequencies above 200 had the highest number of vehicle and cardiorespiratory diseases. Biomonitoring data obtained in cities throughout the year indicate that the number of cardiorespiratory diseases was probably due to vehicular pollution, which is evidenced by the increased frequency of micronuclei in T. pallida.

The flowers of plants of the genus Ludwigia are an important source of food for several species of bees. In the current study, we conducted an experiment with the aim to describe the reproductive biology and phenology of L. nervosa; to identify the species of visiting bees; analyze the foraging behavior of bees; and to investigate whether the reproductive success of the species is related to the foraging activity of bees. We found that the flowers received visits from several native bee species (n = 7), in addition of the exotic honey bees which came to be the dominant species. During visits the majority of the bees foraged in both resources, pollen and nectar. The significantly higher production of fruits in open pollinated pollination experiment compared to artificial cross pollination, suggests honey bees as effective pollinator of this plant species in the study site. Pollen deposition occurs efficiently, given the absence of pollen limitation. Despite massive visitation of honey bees, Ludwigianervosa is attractive to native bees, and therefore it may help to sustain population of both native and exotic pollinators in fragmented humid areas.

We tested the bioactivity of aqueous extracts of Ludwigia spp. (Myrtales: Onagraceae) on the biological cycle of Plutella xylostella. We assessed the duration of and viability during the larval, pupal and adult phases, as well as the influence of the extracts on the fecundity and hatching of P. xylostella eggs. Subsequently, we phytochemically screened the extracts. The extracts of L. tomentosa and L. longifolia reduced the pupal weight instead of prolonging the larval stage of P. xylostella. The L. tomentosa effect caused higher larval mortality and reduced the fecundity and hatching of P. xylostella eggs, and L. sericea reduced the egg survival. The phenolic compounds—flavonoids, condensed tannins and alkaloids—were more abundant in L. nervosa, L. tomentosa, L. sericea and L. longifolia. The L. tomentosa, L. longifolia and L. sericea extracts were bioactive, and these species showed the best results regarding their ability to control P. xylostella populations, because these plants produce substances able to inhibit food consumption and interfere with the morphological and physiological transformations of the offspring and the oviposition of adults.

A produção de mel tem alcançado bons resultados nos últimos anos, mas o país tem potencial para melhorar ainda mais esse desempenho. Portanto, há necessidade de investir cada vez mais em pesquisas nessa área. Objetivou-se com este trabalho promover, acompanhar e avaliar as transformações no Assentamento Areias, localizado no município de Nioaque, após a implantação da apicultura orgânica. Além disso, procurou-se explorar o potencial da área pantaneira, de forma sustentável, na criação de abelhas africanizadas Apis melífera, em Reserva Legal. Buscou-se desenvolver esta atividade de maneira coletiva, como uma proposta agroecológica de geração de renda alternativa e fonte alimentar, reunindo e compartilhando os saberes científicos adquiridos pelos docentes e discentes da Universidade Federal da Grande Dourados/UFGD, e as experiências acumuladas dos assentados com o sistema de produção familiar. O acompanhamento e o alcance dos objetivos estabelecidos foram verificados a cada 30 dias. Entrevistas individuais e reuniões participativas foram realizadas com o grupo de produtores do assentamento de Areias, com o objetivo de coletar dados quantitativos e qualitativos relacionados ao manejo das abelhas e geração de renda. Os resultados foram satisfatórios, pois a apicultura orgânica promoveu um impacto positivo no local, por meio do conhecimento de novas técnicas e aplicabilidade na criação das abelhas. Desta forma, este estudo trouxe subsídios e reflexões para as famílias do assentamento, técnicos, gestores, tomadores de decisão e a sociedade lidarem com a dualidade do sistema convencional de produtividade e o sistema de produção orgânica e agroecológico.

A avicultura sustentável vem ganhando cada vez mais expressividade no mercado. Esse aumento na procura pelo modo de criação de aves semicaipiras se deve a valorização de produtos que são gerados levando em consideração os cuidados com o meio ambiente e com o bem-estar humano e animal. Objetivou-se por meio deste trabalho de extensão promover e acompanhar a produção de aves semicaipiras, que se encontra em fase de transição, de um sistema tradicional para uma criação em sistema orgânico, na Comunidade Quilombola Dezidério Felipe de Oliveira, localizada na Picadinha, município de Dourados, MS. O desenvolvimento desta atividade teve como base os princípios de sustentabilidade e a preocupação em valorizar o trabalho da comunidade, mantendo seu modo de vida tradicional. As práticas foram desenvolvidas no período de novembro de 2017 a setembro de 2018, com o acompanhamento de dois ciclos de produção. As aves foram criadas com milho, ração concentrada e hortaliças produzidas em sistema orgânico. A prática de manejo sustentável de aves reuniu os saberes científicos adquiridos pelos docentes e discentes da UFGD e as experiências acumuladas dos Quilombolas com o sistema de produção animal. Os resultados mostraram um aumento na renda, com venda de 72% das aves adquiridas no primeiro ciclo, e uma melhora no modo de criação das aves do segundo ciclo que proporcionou maior ganho de peso nos frangos de corte. Além disso, com o fortalecimento e desenvolvimento sustentável da produção de aves na comunidade Quilombola, constatou-se uma melhoria na qualidade alimentar das famílias envolvidas no projeto.

The indiscriminate use of synthetic insecticides caused an increase in the resistance of Plutella xylostella (Linnaeus, 1758) (Lepidoptera: Plutellidae) to almost all classes of insecticides, as well as affected the environment and non-target organisms. Thus, the search for less harmful alternatives with the purpose of reducing the application of these insecticides has become a priority. A possible alternative to reduce the use of synthetic insecticides is by using botanical insecticides, given the thousands of existing compounds derived from secondary metabolism in plants. In this study, we tested the following hypotheses: (i) the aqueous and ethanolic extracts of native plants reduce the food consumption of larvae and oviposition of adults of P. xylostella; (ii) these botanical species can act as potential plant insecticides. The objective of this work was to evaluate the effect of plant extracts on the feeding preference of larvae and oviposition of adults of P. xylostella. For this, cabbage discs treated with aqueous and ethanolic extracts of Schinus terebinthifolius, Annona coriacea, Annona crassiflora and Serjania marginata were given to larvae. The concentrations used for the aqueous extracts were of 5 and 10 mg mL-1, and for the ethanolic extracts were of 1 and 5 mg mL-1. Both extracts of the four tested plant species showed oviposition suppressed. The extract of S. marginata showed the lowest rates of suppression. All treatments with ethanolic extracts showed a phagodeterrant effect being that the aqueous and ethanolic extracts of A. crassiflora and S. terebinthifolius were the most effective as antifeedants on third instar larvae by P. xylostella.

Successive applications of insecticides to control Plutella xylostella L. (Lepidoptera: Plutellidae) have resulted in the emergence of resistant populations of this insect. A novel control measure for this target insect could be the use of botanical insecticides derived from plant tissues. Hence, we experimentally tested aqueous extracts of Alibertia edulis (Rich.), Alibertia intermedia (Mart.), and Alibertia sessilis (Vell.) K. Schum. found in the Brazilian savannah in order to investigate their potential to disrupt the life cycle of P. xylostella. Aqueous extracts of the leaves of A. intermedia and A. sessilis negatively affected the development of P. xylostella in all stages of the life cycle, prolonging the larval stage and causing mortality in the larval or pupal stages. Treatments with A. intermedia and A. sessilis extracts caused the lowest fecundity and the number of hatched larvae. The harmful effects of these aqueous extracts on the life cycle of P. xylostella may be attributable to the flavonoids and other phenolic compounds present in A. intermedia and A. sessilis. These aqueous botanical extracts are low in toxicity when compared to non-aqueous pesticides, and may emerge as an effective approach for control of populations of P. xylostella.
