“…Coleoptera group was the most present, being found in the three study áreas. Coleoptera are abundant in Brazilian soils and, although some families are considered pests in agricultural systems, some can contribute to the physical and chemical integrity of the soil (SILVA et al 2012). These organisms act in the incorporation and decomposition of organic matter, being considered indicators of soil quality.…”

The Corn an important role in agriculture, and can be used in both human and animal food, production of ethanol, medicines and glue. However, is verified cultivation practices and soil inappropriate management have led to soil deterioration. Thus, the importance of vegetation cover and the incorporation of organic matter in these cultivated soils. The objective of this work was to evaluate the effect of Carnauba bagana maintained on the soil as mulch and incorporated in macrofauna and soil organic carbon, in the municipality of Itainópolis, in the semi-arid region of Piauí. The areas to be studied will be: corn area with carnauba bagana, as mulch and incorporated into the soil; corn area with uncovered soil and an area of preserved native vegetation. The epigean and edaphic macrofauna will be collected, sorted and identified at the order level. Soil samples will be collected to determine soil organic carbon. Carnauba bagana improved the macrofauna community and soil organic carbon content. The cultivation of corn on uncovered soil reduced the uniformity and diversity of the epigeal macrofauna, the Wealth and Abundance of the edaphic macrofauna and the soil organic carbon content. The variables Larvae, Abundance, Richness, Shannon and Pielou indices, and COS in layers 0.00-0.05 and 0.05-0.10 m were selected for future studies of the impact of maize cultivation in the region.

“…In the present study, management with residual herbicide had an abrupt negative influence on the population of edaphic mites. In studies investigating the influence of residual herbicide on the soil fauna in sugarcane (Saccharum officinarum L., Poaceae) plantations, the herbicide ametryn (triazine), used alone or in association with another herbicide, was shown to also reduce the abundance of soil fauna (Silva et al 2012). This low abundance of soil mites may be a direct result of the breakdown of the proper functioning of the system, which then impacts negatively the soil fauna.…”

Environmental disturbance, as a result of land use change and/or different agricultural practices, may have negative impacts on the richness and abundance of edaphic mites. The objective of this study was to evaluate the effects of different weed management methods in coffee plantations on edaphic mites, and to compare these results with mite communities of native forest habitats in southeastern Brazil. Soil samples were taken between the rows of a coffee plantation under different weed management methods, such as without weeding, manual weeding, agricultural grid, contact herbicide (glyphosate), residual herbicide (oxyfluorfen), mechanical tiller, and mechanical mower, and in a native forest area. Weed management affected edaphic mite communities, with the residual herbicide treatment having the greatest impact on species composition, abundance, richness and diversity. The use of manual weeding and the maintenance of unweeded areas were the practices that preserved mite communities closest to those found in native forest habitats. Thus, such practices are recommended as best practices in coffee plantations. Among the studied mites, the groups Oribatida and Mesostigmata were found in all sites, presenting the greatest abundance and richness, and were sensitive to different forms of weed control. On this basis, we suggest these groups as indicators of soil quality in coffee plantations.

“…Por suas características, são capturados os animais que constituem a fauna epígea, tanto da macro como da mesofauna. O tempo de permanência das armadilhas não é uniforme: a proposição mais frequente é a de sete dias (Antoniolli et al, 2006;Krolow, 2009;Silva et al, 2012Silva et al, , 2014Nunes et al, 2012;Cezar, 2013;Brito et al, 2014), mas há relatos com coletas em um dia (Araújo et al, 2010), dois dias (Ogedegbe e Egwuonwu, 2014), três dias (Baretta et al, 2008), quatro dias (Rovedder et al, 2004) e permanência das armadilhas por 21 dias, com retirada do material biológico a cada sete dias (Cristofolini, 2011). Aquino et al (2006) expuseram os cuidados para uso das armadilhas de queda.…”

resumoA mesofauna edáfica compreende organismos de dimensões entre 100 μm e 2 mm, sendo importante avaliar os métodos utilizados para sua caracterização. Os objetivos deste trabalho foram definir o período de tempo de permanência do material de solo no extrator Berlese-Tüllgren para a captura dos organismos da mesofauna e determinar o tempo mínimo de extração para a correta utilização dos índices de Shannon, Simpson, Pielou e Margalef, empregados na avaliação da diversidade, dominância e equabilidade das comunidades da mesofauna. O estudo foi conduzido no Departamento de Solos do Instituto de Agronomia da Universidade Federal Rural do Rio de Janeiro, Seropédica, Rio de Janeiro, em terreno altamente antropizado. Foram instaladas parcelas experimentais com os seguintes tratamentos: feijão-de-porco (Canavalia ensiformis), mucuna-preta (Mucuna aterrima), feijão-bravo-do-Ceará (Canavalia brasiliensis), guandu (Cajanus cajan) e vegetação espontânea, em delineamento de quadrado latino. Em cada uma das unidades experimentais, foram coletadas amostras formadas por serapilheira e material de solo, nos primeiros 5 cm da camada superficial do solo realizada um dia antes do plantio das leguminosas (outubro) e, posteriormente, por ocasião do corte da parte aérea das plantas (março). As amostras foram submetidas a uma bateria de extratores do tipo Berlese-Tüllgren, por um período de 15 dias, realizando-se a contagem diária dos organismos. A partir da contagem e identificação em nível de grupo (Ordem/Família) dos organismos capturados, foram determinados os índices de Margalef, Simpson, Shannon e Pielou, bem como verificou-se a correlação por ordem de Kendall entre os valores obtidos dia a dia até o 8º dia de extração, usando-se o índice de Shannon como referência. Concluiu-se que é possível a redução do tempo de permanência das amostras de material de solo nos funis Berlese-Tüllgren, não sendo recomendável a adoção Recebido para publicação em 21 de fevereiro de 2015 e aprovado em 24 de junho de 2015.
