“…is associated with the disintegration of fecal masses, which are shaped into spheres and transported over the ground and in ground-excavated galleries (Pompeo et al, 2016;Tissiani et al, 2017), thus contributing to the maintenance of the soil total porosity. Lavelle et al (2006) and Schiavon et al (2014) describe the importance of soil invertebrate fauna as ecosystem engineers, and responsible for modifying the environment, influencing soil dynamics and the ecosystem. Bogoni and Hernández (2014) and Barretto et al (2019) also highlight that this taxon is sensitive to changes in the environment and can thus be used as quality indicators, since its populations may indicate the degree of imbalance in agricultural ecosystems.…”

Soil beetles' communities are responsible for many ecosystem services, and are very sensitive to environmental changes. Thus, this study aimed to evaluate the abundance and diversity of the soil coleoptera fauna under uses and management and also to identify relationships of the beetle community with soil's physical and chemical properties. The experiment had six experimental plots set up an Oxisol (Latossolo): corn (CO), soybean (SO), 7-year-old eucalyptus (EI), 4-year-old eucalyptus (EII), preserved Cerrado (PC), and disturbed Cerrado (DC). Soil beetles were sampled at 128 points for each experimental plot, where the soil physical and chemical properties were analyzed. The Coleoptera fauna organisms were identified at the family, subfamily, and gender level, and then, the number of individuals per day, richness, Shannon diversity indexes, and Pielou evenness were determined. The data were analyzed using multivariate techniques (hierarchical grouping and factor analysis). On total, 750 specimens of beetles were collected, distributed into 9 families, 14 subfamilies, and 27 genera. The most abundant family was Scarabaeidae (11 genera) with the highest occurrence in the PC (143 specimens) and DC (81 specimens). Cultivation with SO presented the greatest number of trap day individuals (ind trap -1 day -1 = 0.548); however, the highest diversity was found in the PC. (20 taxonomic groups) and CO (16 taxonomic groups). Shannon diversity was higher for the CO (H' = 3.107), followed by the PC (H' = 2.699), and the lowest value was found for the SO (H' = 1.530). The similarity dendrogram grouped the plots into two extracts, demonstrating how the intensity of land use influences the abundance and diversity of beetle fauna. The factor analysis grouped the Coleoptera and the physical and chemical soil properties in two factors: elements related to the state of aggregation and porous system's elements. The Coleoptera community was influenced by the intensity of land use and the portion with anthropized natural vegetation showed the highest richness, demonstrating that the Coleoptera fauna responds to environmental changes. Edaphic beetles in the different use and management systems were primarily related to soil physical properties, which explain the state of aggregation (pH, altitude, Ca 2+ , BD, clay, macroporosity, silt, K + , and microporosity) and the porous soil system (sand and total porosity).

Na sociedade do conhecimento, as pessoas são de grande importância para as organizações, pois são elas que possuem conhecimentos, muitas vezes tácitos, essenciais para o desenvolvimento de estratégias que visam ao aumento da competitividade e da produtividade. A busca pela valorização dos diversos saberes está se tornando cada vez mais uma dinâmica em todas as áreas do conhecimento. O processo de modernização da agricultura interferiu no modo de produção dos agricultores que, a partir de uma visão reducionista, buscou homogeneizar a forma de produção, fundamentada nos conhecimentos técnico-científicos, desconsiderando-se os saberes tradicionais das comunidades rurais. Nos últimos anos, estudos têm demonstrado a necessidade de se adotar uma abordagem Inter e Transdisciplinar com a preocupação quanto ao desenvolvimento sustentável, envolvendo diversos tipos de saberes. Assim, o objetivo deste artigo foi analisar o processo da gestão do conhecimento local ou tradicional no contexto da agricultura familiar e demais populações rurais na perspectiva do desenvolvimento rural sustentável, a partir de uma revisão sistemática na literatura. As bases de dados utilizadas para busca foram: web of Science, Scopus, Capes e BDTD. Os resultados das buscas foram oriundos dos seguintes Continentes: Ásia Meridional, Sudeste Asiático, Europa Ocidental, América do Sul e Oceania. Os estudos demonstraram que, na literatura e no meio acadêmico, nos últimos anos, houve uma valorização dos conhecimentos local ou tradicional. No entanto, na prática, ainda são poucas as iniciativas que estimulam o diálogo entre os conhecimentos técnico-científicos e os conhecimentos tradicionais.

“…The pupal stage of H. armigera develops in soil, where they build tunnels around 10 cm deep and form pupal chambers (Araújo, 1990;Ávila et al, 2013). At this stage, the action of natural enemies as pupal predators or parasitoids (Schiavon et al, 2015) may lead the pest to death. Considering the establishment of H. armigera as a pest of maize, the damages caused, and the scarcity of studies on the soil fauna related to the control of agricultural pests, this study intends to investigate its natural control.…”

The natural biological control of soil pests is poorly studied. Notably, the control of Helicoverpa armigera in the pupae stage is unknown. To increase knowledge about the control of this pest in organic and conventional maize crop, tests were conducted to verify if the duration of pupae availability in days, the type of crop treatment (organic and conventional), the stage of crop development, and the depth of the soil significantly affect predation by natural enemies. The pupaeavailability time (days) in the soil did not affect their removal by natural enemies. However, in the fallow stage, on the surface and in the reproductive phase, the predation was higher. In organic maize, predation was 15% higher when compared to conventional maize. The rupture of the soil and the possible losses associated with beneficial fauna were the main factors responsible for higher predation during fallow, so conservationist practices usually used in organic treatment are the main reason for higher predation in this type of crop. There is a significant decrease in the control of H. armigera pests by natural enemies when maize is grown using conventional practices, what reinforces the importance of the conservation techniques used in maize crops.
