Harvest load transfer sites influence sugarcane billbug (Coleoptera: Curculionidae) spatiotemporal injury in sugarcane.

BACKGROUND: The sugarcane billbug, Sphenophorus levis Vaurie 1978, is a key soil-dwelling insect pest of sugarcane in Brazil and greatly affects plant development and yield. This insect presents an aggregated distribution pattern in production fields. The reasons for such behavior include intraspecific communication and attractivity due to the fermentation of sugar in stalk residues. During mechanized harvesting, part of the harvested material usually falls in the load transfer sites, becoming a potential source for increasing the infestation. We therefore evaluated whether producing areas near the harvest load transfer sites are more prone to S. levis injury. RESULTS: There are greater chances of finding billbug injury within a radius of 740 m from the harvest load transfer site. Additionally, injured areas are estimated to expand 11.96% each growing season. Our spatiotemporal models support higher injured areas surrounding the harvest load transfer site and show clear and significant signs of increased injury levels compared to the initial growing season surveyed. CONCLUSION: Our results reinforce the importance of harvest transfer sites in the dispersion and propagation of the sugarcane billbug. Based on this knowledge, sugarcane millers and growers can adopt preventive and remedial practices within the loading sites that can potentially contribute to the successful management of this insect pest. © 2023 Society of Chemical Industry.

Establishing an Integrated Pest Management Program for Coffee Berry Borer (Hypothenemus hampei) in Hawaii and Puerto Rico Coffee Agroecosystems: Achievements and Challenges.

Coffee berry borer (CBB) is the most serious insect pest of coffee worldwide, causing significant reductions in yield and quality. Following the introduction of CBB to Puerto Rico (2007) and Hawaii (2010), researchers, extension agents, industry representatives, and coffee growers have worked together to develop an integrated pest management (IPM) program that is both effective and economically feasible for each island. Since the introduction of the IPM program in Hawaii, research efforts have led to a better understanding of CBB population dynamics, as well as optimized monitoring, cultural practices, and commercial Beauveria bassiana applications. As a result of these efforts, a substantial reduction in average CBB infestation and an increase in coffee yields and quality have been documented in Hawaii over the last decade. However, significant challenges remain in addressing high production and labor costs, limited availability of labor, and a lack of training for field workers in both regions. Although considerable effort has gone into research to support CBB IPM in Hawaii and Puerto Rico, the adoption of these strategies by coffee farmers needs to be increased. More diversified methods of outreach and education are needed to reach growers in rural, isolated areas. Significant gaps exist in the ability and willingness of growers and workers to access and digest information online, emphasizing the importance of on-farm workshops and farmer-to-farmer teaching. Additional methods of training are needed to help coffee farmers and field workers learn how to properly conduct cultural controls and optimize the use of biological control agents such as B. bassiana.

Phytosociological survey of weeds in the grapevine

Viticulture is expanding in the state of Espírito Santo, Brazil. Weed management is essential for the crop, so knowing the floristic composition of weeds in the vineyards makes this practice sustainable. This study aimed to evaluate the floristic composition of weed populations in grape crops in two seasons, considering different altitudes. The experiment was performed in four properties located in Santa Teresa, ES, Brazil, two of which were at altitudes above 500 m of and two below 500 m, in the winter (2018) and summer (2019) seasons. Weeds were identified with the square inventory method. The phytosociological analysis was based on absolute and relative parameters of frequency, density, dominance, importance value index, and relevance index, besides the diversity, evenness, and similarity indices. Fifty species, 41 genera, and 19 families were identified. The most representative families regarding the number of species were Asteraceae, Poaceae, and Malvaceae. In properties with higher altitudes, the species with the highest IVI was Pilea microphylla (L.) Liebm., in both seasons. In properties with lower altitudes, the highest IVI values were found for Malvastrum coromandelianum L. in the winter and Commelina benghalensis and Portulaca oleracea L. in the summer. The areas below 500 m of altitude showed the highest diversity and evenness indices. The proximity between the areas in both regions contributed to the increased similarity index. Altitude and time of the year contribute to the composition of the infesting community.

Dog care and parasitosis in a rural community of Patagonia: An integrative approach.

Human interaction with dogs can potentially lead to zoonoses. The aim of this integrative approach is to describe the relationship between dog parasites, dog care, and the human population of a rural Patagonian village. Surveys were carried out to evaluate owners' attitudes towards dogs, and coproparasitological and coproELISA analyses were performed to determine parasitic infection values. Fur samples and vegetable garden soil were also analyzed. A multivariate regression was performed to identify factors determining infection. All households owned at least one dog, of which only 54.9% had been dewormed in the past three months, and almost half of which were allowed to roam freely. Dogs with protozoan and helminth infections represented 68.8% of the total, 50% being parasitized by helminths of 7 species, including the zoonotic Toxocara canis, Uncinaria sp. Ancylostoma sp. and Echinococcus sp. All hair samples were negative, but 42.8% of vegetable gardens harbored Ancylostomatidae larvae. Statistical analyses indicated that the predictor "time since last deworming" explained infections by Cryptosporidium sp. and helminths, while the predictors "number of dogs per household", "sex", and "freedom to roam" explained the infections by helminths. This shows that the longer the time interval since the last deworming treatment, the greater the probability of a dog being infected by some type of parasite, either Cryptosporidium sp. or a helminth. On the other hand, the probability of being infected by helminths increased when there was more than one dog in the household. Furthermore, male dogs and dogs allowed to roam freely were more likely to be infected. Considering the inadequate care and sanitary status of dogs infected with zoonotic species, it is necessary to raise awareness of the need for responsible care of dogs.

Study protocol of personal characteristics and socio-cultural factors associated with mental health and quality of life of residents living in violent territories.

BACKGROUND: Throughout the world, millions of people living in deprived urban environments with frequent experiences of violence are mentally distressed. There is little evidence about which characteristics of people living in such environments are associated with lower or higher levels of mental distress and how they may cope with experiences of violence. METHODS/DESIGN: This study is part of the research project 'Building the Barricades' (ES/S000720/1 ESRC-AHRC GCRF Mental Health 2017), which uses a mixed-method approach. Quantitative and qualitative studies will be conducted in 16 favelas in the area of Maré in Rio de Janeiro, Brazil. The quantitative study consists of a survey of 1200 randomly selected adults living in Maré and of 200 individuals who frequent the open-use drug sites. The survey will assess sociodemographic characteristics, experiences of different forms of violence, physical and mental health status (including drug use) and active participation in cultural consumption and production. In the qualitative study we will conduct 60 in-depth interviews and 8 focus groups of participants selected from respondents to the survey to assess in more detail their experiences of violence and coping strategies. In order to analyze the quantitative data we will use descriptive statistics and explore associations in uni- and multi-variable analyses. Qualitative data will be subjected to thematic analysis. DISCUSSION: This is an exploratory study to identify characteristics and coping strategies that appear to help people to overcome experiences of violence in deprived areas without developing mental distress. The findings could inform policies to reduce mental distress and improve the quality of life of people living in urban areas affected by violence.

Handmade Comal Tortillas in Michoacán: Traditional Practices along the Rural-Urban Gradient.

Certain components of global food security continue to be threatened. Globalization has impacted food patterns, leading to greater homogenization of diets and the standardization of processes of food transformation, both in the countryside and in the cities. In Mexico, this has led to a drop in the use of native corn landraces and in the value associated with traditional practices around their growing and the processing and consumption of tortillas. The aim of this work was to analyze the main characteristics of the handmade comal tortilla system along the rural-urban gradient taking into account: (1) The type of seed and production, (2) manufacturing processes, (3) marketing channels and purpose of sales, and (4) perceptions regarding the quality of the product. Research was conducted on 41 handmade tortilla workshops located in rural areas in the Lake Pátzcuaro Basin and in urban and peri-urban areas of a medium-sized city in Michoacán (Mexico). Results showed that the origin of the grain follows a gradient-like pattern: In rural areas, tortillas are made with local and native corn predominate, while in urban contexts most tortillas come from hybrid corn produced in Sinaloa or Jalisco. There is a generalized preference for white tortillas, but blue tortillas are used for personal consumption in rural areas and as a gourmet product in the city. 100% of the rural workshops make their own nixtamal, while almost 50% of the peri-urban and urban businesses buy pre-made nixtamal dough. Surprisingly, 50% of the rural handmade tortilla workshops admit that they add nixtamalized corn flour and/or wheat flour to their tortilla mix. We conclude that not all handmade comal tortillas are produced equally and, although in rural areas traditions are better preserved, these also have contradictions. We also conclude that it is important to promote the revaluation of agrobiodiversity, traditional gastronomy, and food security without sacrificing quality, nutrition, and flavor.

(Re)Significações no Processo de Avaliação do Sujeito Jovem e Adulto com Deficiência Intelectual / (Re)Signification in the Assessment Process of Young and Adult Subjects with Intellectual Disability

RESUMO Este artigo objetiva problematizar o processo de avaliação do sujeito com Deficiência Intelectual (DI) e seus efeitos em termos de definição, de classificação e de diagnósticos produzidos sobre a DI. As discussões propostas partem de uma análise referente às diferentes abordagens presentes nos manuais da Associação Americana de Deficiência Intelectual e de Desenvolvimento (AAIDD, 2010 e AAMR, 2006) e suas (re)significações. Procuramos colocar sob tensionamento discursos utilizados para delimitar quem são os sujeitos com DI; que características os constituem; que comportamentos os caracterizam; que potencialidades em termos de aprendizagens eles possuem e que apoios necessitam no contexto educacional. Em articulação com tais análises, apresentamos os dados produzidos no projeto "As contribuições do Rio Grande do Sul para a validação da Escala de Intensidade de Suporte - SIS no Brasil". Amparadas teoricamente nas discussões socioantropológicas propostas por Lev S. Vigotski, tomamos tais dados como elementos para a construção de uma análise que nos possibilite indicar que faz-se possível (e necessário) um olhar para a DI que não parta dos indicadores de QI, historicamente responsável pela delimitação da DI em níveis de severidade, cujas possibilidades de desenvolvimento passaram a ser antecipadamente indicadas pelos diagnósticos clínicos. Nesse sentido, entendemos que, ao deslocarmos a ênfase do diagnóstico do QI para os sistemas de apoio, passamos a perceber um sujeito produzido nas práticas culturais, cujas possibilidades de desenvolvimento e aprendizagem não são exclusivamente determinadas pelos seus aspectos biológicos, mas, sim e principalmente, pelas interações sociais que ele estabelece ao longo de seu desenvolvimento.

ABSTRACT This paper aims at problematizing the assessment process of subjects with Intellectual Disabilities (ID), and its effects in terms of definition, classification and diagnoses produced on ID. The proposed discussions stem from an analysis of the different approaches presented in the manuals of the American Association for Intellectual and Developmental Disability (AAIDD, 2010 and AAMR, 2006) and their (re)significations. We seek to put under tension the discourses used to define who the subjects with ID are; what characteristics constitute them; what behaviors characterize them; what learning potential they have and what supports they need in the educational context. In articulation with these analyzes, we present data produced in the project "The contributions of Rio Grande do Sul for the validation of the Support Intensity Scale - SIS, in Brazil". Based theoretically on the socio-anthropological discussions proposed by Lev S. Vygotsky, we consider the data as elements for the construction of an analysis that indicates the possibility (and necessity) to look at the ID from a perspective other than one that derives from IQ indicators, which are historically responsible for the delimitation of ID in levels of severity, whose development possibilities were previously indicated by clinical diagnoses.

Effects of Early Initiation of Breastfeeding on Exclusive Breastfeeding Practices of Mothers in Rural Haiti.

INTRODUCTION: Rates and relationships of early initiation of breastfeeding (EIBF) and exclusive breastfeeding (EBF) of mothers in rural Haiti were examined. Prelacteal and complementary feedings were identified. METHODS: With a cross-sectional descriptive design, survey data from mothers (N = 195) were collected at three intervals after birth. Data were analyzed for indicators of EIBF, EBF, and complementary feedings. RESULTS: Overall, 148 (75.9%) mothers reported EIBF, and 75 (38.5%) reported EBF. EIBF was associated with EBF, with an adjusted relative risk 1.35 (95% confidence interval = [0.84, 2.18]). Several nutritive and nonnutritive substances interrupted EBF during the first 6 months of life. DISCUSSION: Haiti has an under-five mortality rate of 67.0/1,000 live births, exceeding the mean of 46.5/1,000 live births for developing regions. Both EIBF and EBF are associated with decreased neonatal and early infant mortality. Country-specific data are needed to inform and develop breastfeeding initiatives and community-level campaigns to improve the prevalence of EIBF and EBF in Haiti.

Health-Related Beliefs, Practices, and Experiences of Migrant Dominicans in the Northeastern United States.

Introduction: The purpose of this study was to describe cultural health beliefs, practices, and experiences with professional health care in the United States by migrants from the Dominican Republic because their practices are largely unknown to professional providers. Method: A qualitative descriptive design was used, guided by Leininger's culture care theory and four-phase analysis method with a convenience sample of 15 self-identified migrant Dominican adults in three interpreter-assisted focus groups, in a familiar apartment. Results: The following four themes emerged: Stress affects health and well-being, family support and faith in God are essential, use of folk care and professional care to treat illness and maintain health, and access to care, cost, communication and expressions of caring practices affect perceptions about the quality of professional care. Discussion: Results informed development of specific strategies to provide culturally responsive care and risk-reduction interventions that promote health and improve quality of care in the Dominican community.

The need for frequent monitoring, in addition to the interaction with drugs and foods, as well as the need to transform the everyday life of people who consume it, modify the cultural practices of these patients, and may affect aspects such as adherence. General objective: Describe the cultural practices transformed by people who are part of an anticoagulation program in warfarin therapy. Methodology: Qualitative study type micro ethnography, carried out in Bogotá, Colombia. Results: We had the participation of 10 informants who, associated with the use of warfarin, transformed cultural practices around knowledge, everyday life and emotions.

Merchandising Social como uma Estratégia de Intervenção em Metacontingências: Análise de uma Obra de Ficção Televisiva sobre o Controle do Tráfico de Pessoas no Brasil / Social Merchandising as an Intervention Strategy in Metacontingencies: Analysis of a Work of Television Fiction about the Control of Human Trafficking in Brazil

RESUMO Estudos de fenômenos culturais, a partir da Análise do Comportamento, contribuem para o planejamento cultural ao utilizar estratégias como o merchandising social. O objetivo desta pesquisa foi analisar metacontingências, a partir de um tema social com forte impacto - tráfico de pessoas - em uma novela brasileira de grande audiência: Salve Jorge. As cenas relativas ao tema foram descritas em termos de contingências, classificadas em sete metacontingências, as quais foram apresentadas em alta frequência no transcorrer dos capítulos. O impacto da novela foi observado no aumento da frequência de notícias sobre tráfico de pessoas em seis jornais, além de denúncias registradas nos períodos anterior, simultâneo e posterior à exibição de Salve Jorge. As notícias são indicadores do efeito positivo da obra de ficção sobre o reconhecimento e definição de "tráfico de pessoas", o que contribuei para a frequência de denúncias em órgãos competentes e a implementação das intervenções.

ABSTRACT Behavior-analytic studies of cultural phenomena can contribute to cultural planning by using strategies such as social merchandising. The goal of this research was to analyze metacontingencies based on a social theme of great impact - human trafficking - in a Brazilian soap opera (Salve Jorge) with a large audience. Scenes related to the theme were described in terms of contingencies, classified in seven metacontingencies, which were presented in high frequency throughout the chapters. The impact of the soap opera was observed in the increased frequency of news about human trafficking in six newspapers as well as complaints registered in the periods before, simultaneous and after the exhibition of Salve Jorge. The news is indicative of the positive effect of a work of fiction on the recognition and definition of "human trafficking", which also contributes to a higher frequency of complaints and interventions implemented by competent agencies.

Mangrove Economy: etho-politics and social change / Economía del manglar: etho política y cambio social / Economia de manguezais: etho-política e mudança social

ABSTRACT An advance of the research project «Bio-entrepreneurship: productive configuration of agroecosystems¼ is presented. The interpretative framework is based on political concepts, economy and social change, also on relations between capitalism, modernity and the nation-state. At the same time, there are observed alternative cultural practices from Afro-descendant women in their territories, their banishments and their ancestral legacy in the colombian pacific coast. It was found that meanings emerge through the stories told by them, which talk about an economy that runs on a space-time in/from the re-existence of human groups. The human groups that inhabit the ancestral territory and the ones that were banished from the mangrove and that recreate it and make it come alive in different contexts (including the urban popular).

Integrated Pest Management of Coffee Berry Borer in Hawaii and Puerto Rico: Current Status and Prospects.

The coffee berry borer (CBB), Hypothenemus hampei, is the most significant insect pest of coffee worldwide. Since CBB was detected in Puerto Rico in 2007 and Hawaii in 2010, coffee growers from these islands are facing increased costs, reduced coffee quality, and increased pest management challenges. Here, we outline the CBB situation, and summarize the findings of growers, researchers, and extension professionals working with CBB in Hawaii. Recommendations for the Integrated Pest Management (IPM) program for CBB in Hawaiian Islands and Puerto Rico include: (1) establish a CBB monitoring program, (2) synchronize applications of insecticides with peak flight activity of CBB especially during the early coffee season, (3) conduct efficient strip-picking as soon as possible after harvest and perform pre-harvest sanitation picks in CBB hotspots if needed, (4) establish protocols to prevent the escape of CBB from processing areas and when transporting berries during harvest, and (5) stump prune by blocks. Progress achieved includes the introduction of the mycoinsecticide Beauveria bassiana to coffee plantations, the coordination of area-wide CBB surveys, the establishment and augmentation of native beetle predators, and an observed reduction of CBB populations and increased coffee quality where IPM programs were established. However, CBB remains a challenge for coffee growers due to regional variability in CBB pressures, high costs, and labor issues, including a lack of training and awareness of CBB management practices among growers.

Berry-cluster thinning to reduce compactness of Black Star table grapes / Despenca como método de raleio para reduzir a compacidade de cachos da uva de mesa Black Star

The berry-cluster thinning technique was evaluated at different phenological times to prevent bunch compactness of Black Star table grape, a new somatic mutation of Brasil grape. The trial was carried out during 2012 and 2013 seaons in a vineyard situated in Marialva, PR, Brazil. Vines were trained in an overhead trellis system and spaced at 3x4m. The randomized block design was used as a statistical model with fi ve replications and fi ve treatments. The following treatments were evaluated: control; brushing prior to anthesis; and berry-cluster thinning at different times, when berries were 3-6, 7-10, or 11-15mm in diameter. The prevalence of bunch compactness was evaluated considering the levels: loose, medium loose, and dense bunches. The main physico-chemical characteristics of grapes and yield were also appraised. The data obtained were submitted to ANOVA, and toTukeys test at 5% was applied. So, thinning is a mandatory practice to avoid bunch compactness of Black Star grapes. The technique has to be performed, preferably, by means of brushing prior to anthesis, and the failure to accomplish this practice at this time, berry-cluster thinning when berries are 11-15mm in diameter can be used.

As videiras foram conduzidas em latada em espaçamento 3x4m, e o experimento foi realizado nas safras 2012 e 2013. O delineamento experimental consistiu em blocos casualizados, com cinco repetições e cinco tratamentos: controle sem raleio; raleio com escova plástica realizado no pré-florescimento e; despenca quando as bagas apresentavam 3-6, 7-10 ou 11-15mm de diâmetro. A compacidade predominante dos cachos foi avaliada de acordo com a seguinte classificação: cachos soltos, medianamente soltos e compactos. As características físico-químicas dos cachos e a produtividade também foram avaliadas. Os dados foram submetidos à análise de variância e as médias comparadas pelo teste de Tukey a 5%. Verificou-se que o raleio de bagas é uma prática obrigatória na uva Black Star para diminuir a compacidade dos cachos. A operação deve ser realizada, preferencialmente, com a escova plástica no pré-florescimento, e na impossibilidade de executar ou finalizar essa prática nesta fase, pode-se empregar a despenca quando as bagas apresentarem 11-15mm de diâmetro.

Este artigo analisa dimensões ético-tecnológicas da Análise Comportamental da Cultura. Mais precisamente, a partir de uma seminal publicação de J. G. Holland, na qual o autor indaga se os princípios comportamentais serviriam aos movimentos revolucionários, examina aspectos derivados da formação acadêmica, da história pessoal de interações e do problema da justificação racional de valores, que constituem condições cruciais para a delimitação dos objetivos dos delineamentos culturais. Considerando ser indissociável do planejamento alguma transformação social, são discutidas alternativas de engajamento do analista comportamental em projetos que contribuam para a consolidação da justiça social.(AU)

This paper analyzes the ethical and the technological dimensions of the Behavioral Analysis of Culture. More precisely, the analysis takes as starting point the seminal publication by J. G. Holland, in which he inquires about whether the behavioral principles would be of any value to revolutionary demonstrations, examines the aspects that are closely related to an individual’s academic background and personal history of interactions, and to the rational justification of values, all of which constitute crucial conditions in establishing the purposes of cultural designs. Considering that social transformation is inseparable from cultural planning, this paper discusses alternatives to the involvement of behavior analysts in projects that contribute to social justice consolidation.(AU)

Este artículo analisa dimensiones ético-tecnológicas de la Análisis Conductual de la Cultura. Mas precisamente, a partir de una original publicación de J. G. Holland (1974), donde el autor pregunta si los principios conductuales pudieran servir a los movimentos revolucionarios, examina aspectos derivados de la formación académica, de la historia personal de interacciones y del problema de la justificación racional de valores, que son condiciones cruciales para la delimitación de los objectivos de los delineamientos culturales.(AU)
