Abstract—A synopsis of Dicliptera (Acanthaceae) for Brazil is presented. Six species are recognized: Dicliptera ciliaris, D. sexangularis, and D. squarrosa, widely distributed in South America; D. purpurascens, which ranges from the North Region of Brazil (in the state of Acre) to eastern Bolivia; D. gracilirama, a new species from the Atlantic Forest of northeastern Brazil; and D. granchaquenha, a new species recorded in dry and semideciduous forests in Bolivia and western Brazil, in the state of Mato Grosso do Sul. Furthermore, we propose new synonyms and designate lectotypes for eleven names. An identification key to the six accepted Dicliptera species in Brazil is provided.

Title in Portuguese: Funções de migração por idade e caracterização de migrantes das microrregiões de Goiás e Distrito Federal, 1975-1979 e 1986-1990(Dissertação de Mestrado)(M.A. Thesis)Since the 70’s, the Brazilian Middle-West Region has experienced an important modernization process in agricultural and industrial activities, which has led to an employment retraction and migration flows, especially from rural areas to the major metropolitan cities of the region. In this research the focus of analysis are the State of Goiás and the Federal District, which encompasses Brasília, the capital of Brazil. In order to understand the new population configuration, the region was divided into four sub-areas (micro-region of Goiânia, micro-region of Entorno de Brasília, the Federal District, and a group of 16 micro-regions of Goiás) and the patterns of migration, by age and sex, were estimated for the periods 1975-1979 and 1986-1991. In addition, differences between native and migrant population of each sub-area, according to the participation in the labor force, income, education and type of migration were investigated. The analysis was performed on the basis of the 1980 and 1991 Brazilian Census data.In the intra-state migration, the fluxes between the micro-region of Goiânia and the 16 other micro-regions of Goiás, and between the Federal District and the micro-region of Entorno de Brasília were the most important. In the inter-state migration, the flux from the states of Mato Grosso, Mato Grosso do Sul and the North region to the 16 micro-regions of Goiás, as well as the flux from Northeast, Southeast and South to the Federal District were significant. But there was a decline in the migration to the Federal District, between 1975-1979 and 1986-1991, while, in the same period, the migration to the Entorno of Brasília increased.The chance of the migrant population in the micro-region of Goiânia and in the Federal District to have worked in the last 12 months prior to census interview was lower than that of the native population. However, those who migrated from the Federal District to the micro-region of Entorno de Brasília had higher chance to have worked in the formal sector than those who did not migrate. Migrants who moved from the micro-region of Entorno de Brasília and the 16 other micro-regions of Goiás to the micro-region of Goiânia had lower wages than the non-migrant population. The lowest level of wages was recorded for the migrants to the 16 other micro-regions of Goiás. Migrants living in the Federal District had high level of education, while those migrants living in the micro-region of Entorno de Brasília had low level of education.In 1986-1990, the micro-regions of Goiânia and Entorno de Brasília, as well as the 16 other micro-regions of Goiás, presented a high percentage of returned migrants. In the same period, a major proportion of migrants to the micro-region of Entorno de Brasília had first moved from Southeast or from the Federal District to others regions. In addition, there was a considerable proportion of migrants with low income who had moved from Northeast to the Federal District and then to the micro-region of the Entorno de Brasília.Future research could focus other areas or regions of Brazil, and could also explore the same kind of analysis, on the basis of the incoming 2000 Brazilian Census, which requires the development of new techniques, as it did not collect information on the city of previous residence, but only on the state of residence.

The present work had the objective of quantifying corn grain losses in road transportation along a section of highway BR 163 in the state of Mato Grosso. The survey was done in July and August of 2016 in the section between the Imigrantes Highway, within the city of Cuiabá - MT, and the municipality of Nova Mutum – MT. This stretch is considered to be the one with the highest flow of grain loads in the state of Mato Grosso. Twenty one collect points were established along the stretch, with a distance of 10 km from one point to the other, at each collect point 3 areas of 1 m² were delimited with the aid of a fixed frame of wood with the same area, in a distance of 1.3 m from the highway margin, in the north-south direction, which is the direction of the grain flow. The samples were placed in identified plastic bags and taken to the laboratory for separation and weighing. The points of the biggest grain losses were points 06 and 12 of the section, where it was verified pavement in poor quality with much road surfacing, and the points of lower losses were collected in the top quality asphalt range.

Commonly found in Mato-grossense Cerrado, the pequi tree (Caryocar brasiliense Camb) produces a fruit called pequi, which is sold and consumed by the population where it is produced, in cream, candies, ice creams or in natura, as a typical regional side dish. It is a highly nutritious fruit and hence necessary to the population. The aim of this study was to proceed with the biometric and physical-chemical analysis of pequis collected in the north of the state of Mato Grosso, to contribute with a database to help identify good genoptypes for commercial and industry usage, to build a germplasm bank. Whole fruits from seven different matrixes of Caryocar brasiliense Camb were randomly collected in União do Sul-MT, seasons 2017 and 2019. The mass, transverse diameter, longitudinal diameter, volume and sphericity of fruits and pyrenes have been determined, as well as the number of pyrenes per fruit and pulp mass. The pulp was analyzed for its moisture, pH, total titratable acidity and soluble solids contents. The physical evaluation for fruits and pyrenes show that the observed matrixes had statistically significant differences in all parameters tested, especially on mass, volume and pulp mass. The pequis from matrix 7 have the best results for whole fruit and pyrenes mass, and also for pulp mass and pulp mass/whole fuit ratio. The results for moisture and physical-chemical analysis show that the observed matrixes presented statistically significant differences. The findings are similar to the ones detected in studies with pequis in other regions. Based on the results obtained, the fruits that have been analyzed may be regarded as of interest for business and industry, therefore may be considered to build a germplasm bank.

Phlebotomine sand flies are insects of medical importance, as they are vectors of viruses, bacteria and trypanosomatids of the genus Leishmania Ross, the causative agent of leishmaniasis (Forattini 1973). During the past 20 years approximately 500,000 cases of leishmaniasis have been reported in Brazil. Most of these cases were reported in the North and Northeast regions. In the State of Roraima, almost 2,000 cases, including both cutaneous leishmaniasis (CL) and visceral leishmaniasis (VL), have been reported during the past three years (SINAN 2017). Usually the transmission by infected female sand flies occurs in wild or rural areas, but there have also been recorded cases and vector captures in urban environments. Some sand fly species are known to enter houses in search of resting places and blood meal sources; as a result of this behavior, they are remarkably adaptable to new environments (Carvalhoet al. 2010).

The Latin American Integration Route (RILA) corresponds to the materialization of an old desire to integrate the peoples of South America. This route will connect important municipalities in Brazil, Paraguay, Argentina, and Chile. In the state of Mato Grosso do Sul (MS), it will connect important municipalities, and bring opportunities and threats. The objective of the study was to analyze the productive structure of the municipalities in Mato Grosso do Sul that will be directly affected by the RILA to better understand this process. For this purpose, we used an Exploratory Spatial Data Analysis (Spatial EDA) and the spatial Locational Quotient (sLQ) of the sectorial jobs of the municipalities of the State. The results point out a spatial inequality in productive sectors, delimiting "sectorial islands". In the industrial sector, the northeastern regions and the surroundings of the capital, Campo Grande, stand out. The northeast region of the State also stands out in the Civil Construction sector and, together with the north-central part of the MS, in the agriculture and livestock sector. In the trade sector, the southern region of the MS stands out, with proximity to Paraguay. In the services sector, there is a relative concentration in the capital and the extreme south of the State. In conclusion, we point out the urgent need for public policies to expand opportunities and mitigate the threats of integration managed by the route.

The objective of this work was to compare the leaflet severity of Asian soybean rust in farms sown in December and February in the state of Mato Grosso. In the survey, 28 fields were sampled in 14 counties in the North, West and South regions of the state. A total of 40 leaflets were collected per plot, in randomized treatments with four replication and three crop phenological stages. Leaflet severity was assessed according to a diagrammatic scale. The data were expressed as leaflet severity, submitted to linear regression analysis, calculated the area under the disease progress curve (AUDPC) considering the three phenological stages sampled, and the means compared by the Tukey’s test. Leaflet severity was significantly higher in the fields sown in December than in February, as well the number of fungicides sprayings. Our results indicate that the proposed change in seeding time from December to February can be implemented by significantly reducing risks and in compliance with the principles of IN 002/2015.
