ABSTRACT This paper aimed to evaluate the occurrence of Gonodonta larvae defoliating sugar apple (Annona squamosa) and atemoya fruits (Annona squamosa x Annona cherimolia L. Mill.) in northern state of Minas Gerais. Larvae were collected between December 2007 and January 2008 in Annonaceae plantation in the rural area of the municipality of Janaúba, MG. Adults obtained have been sent for identification. The species identified were Gonodonta bidens Geyer, G. nutrix Stoll and G. pyrgo Cramer. The infestation level observed in the orchard was 85% of plants with the presence of Gonodonta larvae and the average defoliation percentage was 30%. These are the first records of Gonodonta species defoliating sugar apple and atemoya in Brazil.

Abstract Anthracnose stands out among rot diseases that can occur in the post-harvest phase of banana. The aim of this study was to evaluate the thermotherapy in the control of anthracnose in ‘Prata Anã’ banana produced in northern state of Minas Gerais. Bananas ‘Prata Anã’ variety were divided into groups of three fruits and inoculated with Colletotrichum musae. Groups were submitted to thermotherapy using five temperatures (40°C, 44°C, 48°C, 52°C and 56°C) and four immersion times (4, 8, 12 and 16 minutes) and control. Treatments were repeated five times in a completely randomized design. Area under the incidence progress curve (AUIPC) and area under the severity progress curve (AUSPC) were calculated. To evaluate the thermotherapy efficiency compared to chemical control, fruits were submitted to the following treatments: thermotherapy with and without fungicide application and fruits treated with fungicide only, the control fruits without thermotherapy and without fungicide application. After fifteen days of storage, fruits were evaluated for anthracnose severity. The results of experiments were submitted to analysis of variance and regression and means were compared by the Scott-Knott test (p<0.05). Control was compared to treatments by the Dunnett test (p<0,05). The lowest anthracnose AUIPC values were observed when using temperature of 48°C for eight and 12 minutes. Thermotherapy at 52°C from eight minutes of immersion, in addition to reducing the anthracnose AUSPC in fruits up to 81.6%, delayed maturation of fruits. Fruits submitted to thermotherapy at 56°C presented higher severity of the disease and resulted in the maturation of fruits. Thermotherapy reduces anthracnose severity in fruits in a manner similar to fungicide use, but the association of both results in better control of the disease in ‘Prata Anã’ banana. Thermotherapy is an efficient technique to reduce the severity of the disease in ‘Prata Anã’ banana produced in northern state of Minas Gerais.

We evaluated the occurrence of intestinal parasites and commensals among children and adults from a landless camping in the rural area of Uberlândia, State of Minas Gerais, Brazil, from October to November 2001. Stool samples from 78 individuals were examined by both the Baermann-Moraes and Lutz methods. Fifty-one (65.4%; CI 54.8 - 76.0) individuals were found to be infected, 23 (45.1%) children and 28 (54.9%) adults, of whom 34 (66.7%) were mono-infected, 9 (17.6%) bi-infected, and 8 (15.7%) poly-infected. In conclusion, the high prevalence of intestinal parasites and commensals suggests that parasitological exams should be periodically carried out in addition to the sanitation education and health special care in this population.

A mesorregião do Norte de Minas Gerais apresenta-se como uma das áreas de menor valor comercial da terra no estado, juntamente com o Vale do Jequitinhonha. Com isso, a aquisição da terra para a implantação de projetos de silvicultura, especificamente o eucalipto, foi facilitada. O eucalipto demanda grandes áreas, por isso o preço da terra é uma variável importante para o sucesso econômico do empreendimento. Nesse contexto, este artigo analisou a distribuição espacial desse tipo de cultivo no norte do estado de Minas Gerais, nos anos de 1986, 1996 e 2010. Para isso, foram usados produtos orbitais de média resolução para extrair as áreas de eucalipto. Esses dados foram sobrepostos, através do SIG, a outras características dessa região. Com isso, foi possível identificar a dinâmica dessa silvicultura que, de acordo com os resultados, vem reduzindo a área ocupada no norte de Minas Gerias. Abstract SPATIAL-TEMPORAL ANALYSIS OF EUCALYPTUS IN THE NORTH OF MINAS GERAIS IN THE YEARS 1986, 1996 AND 2010 The northern region of Minas Gerais presents itself as an area of lower commercial value of the land in the state. Thus, land acquisition for the implementation of forestry projects, especially eucalyptus, was facilitated. Eucalyptus demand large areas, so the price of land is an important variable for the economic success of the enterprise. In this context, this paper analyzed the spatial distribution of such cultivation in the northern state of Minas Gerais, in the years 1986, 1996 and 2010. Thus, we used medium-resolution orbital products to extract the areas of eucalyptus. These data were overlaid through GIS, other characteristics of this region. Thus, it was possible to identify the dynamics of this forest, which, according to the results, has been reducing the area occupied in the north of Minas Gerais.

O objetivo do artigo é avaliar e comparar a situação de segurança alimentar domiciliar por três diferentes métodos, em área rural de uma cidade brasileira: disponibilidade de energia alimentar em casa; estado nutricional; e percepção de insegurança alimentar. Trata-se de estudo transversal realizado com 79 famílias residentes em 19 comunidades rurais de um município de Minas Gerais, totalizando 272 moradores. Durante as visitas familiares, o estado nutricional foianalisado por antropometria, a percepção de insegurança alimentar pela Escala de Insegurança Alimentar (Ebia) e a disponibilidade de energia alimentar no domicílio por 30 dias. Os resultados mostraram que, das 79 famílias de agricultores familiares, 12,7% foram consideradas inseguras para a disponibilidade de energia alimentar, 24,0% devido à presença de baixo peso em casa e 49,5% por Ebia. Houve baixa correlação entre os métodos, com diferenças entre eles (Kendall W 0,162 p <0,001). A insegurança alimentar esteve associada à presença de pelo menos um indivíduo com idade inferior a 18 anos no domicílio. A segurança alimentar classificada de acordo com a Ebia foi associada a um aumento no número de pessoas que vivem no domicílio, na produção de vegetais e frutas. Concluiu-se que nenhum indicador isolado pode cobrir várias dimensões da segurança alimentar, a qual envolve uma abordagem ampla e multifacetada; portanto, sua avaliação completa requer diferentes métodos de classificação.
