Antiteuchus tripterus (Fabricius, 1787) (Heteroptera: Pentatomidae): First Record of This Native Stink Bug Damaging the Threatened Araucaria angustifolia in Brazil.

This is the first report of Antiteuchus tripterus (Fabricius, 1787) (Heteroptera: Pentatomidae) damaging Araucaria angustifolia (Bertol.) Kuntze, 1898 (Pinales: Araucariaceae) plants in Brazil. This bug, native to the neotropical region, damaged this plant on fragments of mixed rain forest in Bueno Brandão, Minas Gerais state, Brazil. Araucaria angustifolia, native and with ecological and economic values, was widely used in the lumber market and, therefore, threatened with extinction. Nymphs and adults of A. tripterus were observed in March and April with a population reduction until June 2022. The bioecology and damage caused by A. tripterus on A. angustifolia are not known.

Metarhizium carneum Formulations: A Promising New Biological Control to Be Incorporated in the Integrated Management of Meloidogyne enterolobii on Tomato Plants.

The increase in the populations of root-knot nematode Meloidogyne enterolobii in various vegetables such as tomatoes grown under greenhouse conditions as well as increasing restrictions on the use of certain chemical nematicides have led to the search for new, effective management strategies, preferably ones that are sustainable biological alternatives. In this work, two formulations of the nematophagous fungus Metarhizium carneum, one concentrated suspension and one wettable powder, were evaluated under greenhouse conditions to reduce the M. enterolobii infestation in tomato plants. In addition, the effectiveness of the liquid formulation of M. carneum was compared with two biological and three chemical commercial nematicides. The results show that the two M. carneum formulations reduced the M. enterolobii population density by 78 and 66% in relation to the control treatment. In comparison, the liquid formulation of M. carneum and Purpureocillium lilacinum treatments reduced nematode population density by 72 and 43%, respectively, while for metam sodium preplanting applications followed by M. carneum applications during the tomato growth stage, the reduction was 96%. The alternate use of some chemical compounds plus the application of M. carneum as a biocontrol is a good starting strategy for managing M. enterolobii populations. These results confirm that M. carneum is a serious candidate for the short-term commercialization of an environmentally friendly biological nematicide.

Antibiotic Prescription Patterns in Children Under 5 Years of Age With Acute Diarrhea in Quito-Ecuador.

BACKGROUND: Diarrheal disease remains a significant cause of child mortality, particularly in regions with limited access to healthcare and sanitation. Inappropriate practices, including unjustified medication prescriptions, pose challenges in the management of acute diarrhea (AD), especially in low- and middle-income countries. OBJECTIVE: This study analyzed antibiotic prescription patterns and assessed compliance with Integrated Management of Childhood Illness (IMCI) guidelines in children under 5 with AD in the Ministry of Public Health (MOPH) Ambulatory Care Centers of Quito city, Ecuador. METHODS: A cross-sectional design was used, collecting electronic health records (EHR) of patients diagnosed with AD from 21 health facilities in District 17D03. A probabilistic and stratified sampling approach was applied. Patient characteristics, prescriber characteristics, treatments, and compliance of IMCI guideline recommendations were evaluated. A stepwise logistic regression analysis examined the association between antibiotic prescription and patient and physician characteristics. RESULTS: A total of 359 children under 5 years of age were included, with 58.77% being girls. 85.24% of the cases of AD were attributed to gastroenteritis and colitis of infectious and unspecified origin. Amebiasis and other protozoal intestinal diseases accounted for 13.37% and 1.11% of the cases, respectively. The completion rates of recording various IMCI parameters varied; parameters such as duration of diarrhea, presence of blood in stool, and evidence of sunken eyes had high completion rates (100%, 100%, and 87.47%, respectively), while parameters like state of consciousness, presence of thirst, and type of diarrhea had low completion rates (0.28%, 0.28%, and 0.84%, respectively). None of the cases had all parameters fully recorded. Antimicrobials were prescribed in 38.72% of the cases. Children aged 3 to 5 years had higher odds of receiving antimicrobial prescription for AD (aOR: 4.42, 95% CI 2.13-9.18, P < .0001) compared to those under 1 year, after adjusting for the number of loose stools per day, gender, and age of the health professional. CONCLUSION: Variations in IMCI guideline compliance were observed, with no cases fully adhering to the guidelines. Antimicrobial prescription rates were notably high, especially among older children. Further research and specialized interventions are necessary to gain comprehensive insight into the factors underlying non-compliance with the IMCI guidelines.

Conclusions: Lean tools allow a comprehensive analysis of the patients' flow, in addition to showing a route for their management, focused on the trajectory and not on the occupation of the resource.

Environmental performance of phytosanitary control techniques on soybean crop estimated by life cycle assessment (LCA).

Phytosanitary control is essential to ensure agricultural productivity and quality. However, approaches based on scheduled use of pesticides, overuse of harmful molecules produce impacts on different types of living organisms. Integrated Pest and Disease Management (IPM-IDM) may significantly reduce the burden of pesticides in the environment. Plant resistance may also be included in the IPM-IDM and even in conventional management due to little requirement of additional knowledge and changes in agricultural practices. Robust environmental assessments using methodology of universal use, life cycle assessment (LCA), may estimate the impacts of specific pesticides that cause major damages, including remarkable category impacts. Therefore the objective of this study was to determine the impacts and (eco)toxicological effects of phytosanitary strategies (IPM-IDM including or not lepidopteran resistant transgenic cultivars) vs. the scheduled approach. Two inventory modeling methods were also applied to gather information on the use and applicability of these methods. Life cycle assessment (LCA) was applied using two inventory modeling methods: 100%Soil and PestLCI (Consensus) using data from Brazilian croplands under tropical conditions, by combining phytosanitary approaches (IPM-IDM, IPM-IDM + transgenic cultivar, conventional, conventional + transgenic cultivar) and modeling methods. Hence, eight soybean production scenarios were established. The IPM-IDM was efficient to reduce the (eco)toxicity impacts of soybean production mainly for freshwater ecotoxicity category. Due to the dynamic character of IPM-IDM approaches, the inclusion of recently introduced strategies (plant resistant and biological control to stink bugs and plant fungal diseases) may diminish even more the principal impacting substances throughout the Brazilian croplands. The PestLCI Consensus method, although its development is yet in progress, to date can be suggested to estimate the agriculture environmental impacts more properly under tropical conditions.

Pharmacopuncture with a low dosage of B complex vitamins in the Da Zhui acupoint (Governing Vessel 14) for controlling gastrointestinal parasitism in periparturient ewes / Farmacopuntura com dose baixa de vitaminas do complexo B no acuponto Da Zhui (Vaso Governador 14) para o controle da parasitose gastrintestinal em ovelhas no periparto

Gastrointestinal parasites are a significant challenge in sheep farming, and periparturient ewes are one of the most susceptible categories in sheep flocks. This study aimed to verify whether the injection of B vitamins at the acupuncture point governing vessel 14 (GV14) can influence the parasitic load or host-parasite interaction in naturally infected ewes during the peripartum period. Four weeks before parturition, 25 ewes were divided into five treatment groups: (1) Dose Control: 0.2 mL of B complex via IM; (2) Drug Control: 2 mL Complex B via IM; (3) Acupoint Control: 0.2 mL of Water at GV14 point; (4) Control; (5) Test group: 0.2 mL of B complex at the GV14 point. Treatments were performed at weeks -3, -1, 2, 4, and 6 about the parturition time. Fecal samples to estimate the parasitic load by fecal egg counts (FEC) and total blood samples for hemogram examination were performed seven days after the treatment, coinciding with weeks -2, 3, 5, and 7 about the parturition time. The number of peripheral eosinophils was higher in group 3 than in group 1 (p <0.05). Although groups 3 and 5 had lower mean values of FEC and higher hematological values at the time of weaning, these differences were not statistically significant (p> 0.05) according to the F test. However, all animals in groups 3 and 5 maintained low parasitism levels until the end of the experiment. Further studies should be performed with larger sample sizes and minor changes to the experimental protocol to elucidate the role of GV14 acupoint stimulation in the host-parasite relationship.(AU)

A parasitose gastrointestinal é o principal desafio sanitário para a criação de ovinos a pasto, e as ovelhas no periparto são uma das categorias mais susceptíveis a esta infeção no rebanho. O objetivo deste trabalho foi verificar se a injeção de vitaminas do complexo B no acuponto Vaso Governador 14 (VG14) poderia influenciar a carga parasitária ou modular a interação hospedeiro-parasito em ovelhas naturalmente infectadas no período de periparto. Quatro semanas antes da data prevista para o parto, 25 ovelhas foram divididas em cinco grupos de tratamento (1) Controle da dose: 0,2 mL de vitaminas do complexo B via IM; (2) Controle do fármaco: 2mL complexo B via IM; (3) Controle do Ponto: 0,2 mL de água destilada no ponto VG14; (4) Controle sem tratamento; (5) Grupo teste: 0,2 mL de complexo B no pontoVG14. Estes tratamentos foram realizados nas semanas -3; -1; 2; 4 e 6 em relação à data do parto. Amostras de fezes para contagem de ovos por grama de fezes (OPG), assim como amostras de sangue para realizar o hemograma, foram obtidas dos animais sete dias após os tratamentos, coincidindo com as semanas -2, 3, 5 e 7 do parto. O número de eosinófilos periféricos foi superior no grupo 3 se comparado ao grupo 1 (p <0,05). Os animais dos grupos 3 e 5 tiveram menores valores de OPG e maior hematócrito, mas estas diferenças não foram consideradas significativas pelo teste F (p> 0,05). No entanto, todas as ovelhas dos grupos 3 e 5 se mantiveram com níveis baixos de parasitismo durante todo o experimento. Sugere-se que novos estudos sejam realizados com algumas modificações deste protocolo a fim de aprofundar o conhecimento do potencial imunomodulador do acuponto VG14.(AU)

Laboratory Evaluation of Storage Bags for Infestations in Wheat Caused by Rhyzopertha dominica F. (Coleoptera: Bostrichidae) and Trogoderma granarium Everts (Coleoptera: Dermestidae) and Their Control Using Phosphine Fumigation.

Bag storage of wheat is common in Asian countries, and common types of such bags include jute bags, woven plastic bags, and hermetic plastic bags. In order to assess infestation by two serious pests, namely Rhyzopertha dominica (Coleoptera: Bostrichidae) and Trogoderma granarium (Coleoptera: Dermestidae) in these bags, two experiments were performed. In the first experiment, three popular wheat varieties, namely Akbar, Dilkash, and Bakhar star were filled in above-mentioned miniature-size bags which were then placed in jars with three replicates per bag type and variety. Forty insects (adults for R. dominica and larvae for T. granarium) were released in the center of the jars for a period of 30 d in two different setups for both species. Data were recorded twice: after 15 d and 30 d. Results showed insects entered the jute bags only (made invasions due to its loose fibers and openings). Inside the bags, R. dominica caused more weight loss and live insects in Dilkash and Akbar varieties, while T. granarium preferred Bakhar star and Dilkash compared with their third variety. In the second experiment, only two bags, namely woven plastic bags and hermetic plastic bags filled with one variety, were tested to check damage (penetrations because no openings are present in these bags as in jute bags) to the bags. Results showed both species created holes in woven plastic bags but not in hermetic plastic bags. These results showed hermetic plastic bags remained safe from external infestation compared with the other two bags. Sometimes if insects are already present in the grains inside the bags, fumigation is needed from outside to kill the pests inside. To evaluate this, all three bags were filled with a wheat variety and were also infested with both insect species and placed in a fumigation container with nine replicates per bag type. A phosphine tablet (3.0 g) wrapped in muslin cloth was placed in a container which was then sealed, and the fumigation-induced mortality after 24 h was recorded. Results showed mortality was >95% to 100% in woven and jute bags, respectively, while mortality in hermetic plastic bags remained very low (<3%). These results revealed the least fumigant gas permeation in hermetic plastic bags compared with jute and woven plastic bags. Results of all three experiments demand immediate alteration in creation of all three bags to curtail infestation from outside (jute and woven plastic bags) as well as to generate maximum fumigation efficacy when the source of infestation is with the grains (hermetic bags).

Available Strategies for the Management of Andean Lupin Anthracnose.

The lupin (Lupinus mutabilis Sweet) is a legume domesticated and cultivated for more than 4000 years by the pre-Hispanic cultures of the Andean zone. Due to its good taste and protein content, the lupin seed contributes significantly to the food and nutritional security of the Andean population. However, lupin is susceptible to diseases, and of these, anthracnose is the most devastating as it affects the whole crop, including leaves, stems, pods, and seeds. This review focuses on available strategies for management of lupin anthracnose from sowing to harvest. Seed disinfection is the primary anthracnose management strategy. Seed treatment with fungicides reduces transmission from seed to seedling, but it does not eradicate anthracnose. Attention is given to alternative strategies to limit this seed-borne pathogen as well as to enhance plant resistance and to promote plant growth. For anthracnose management in the field, integrated practices are discussed that encompass control of volunteer plants, lupin ontogenetic resistance, and rotation of biocontrol with chemical fungicides at susceptible phenological stages. This review covers some local experiences on various aspects of anthracnose management that could prove useful to other the groups focusing on the problem.

Heterorhabditis amazonensis to Control Euschistus heros (Hemiptera: Pentatomidae) in Laboratory and Field Conditions.

This study evaluated the potential of entomopathogenic nematodes (EPNs) to control Euschistus heros (Fabricius) under laboratory and field conditions. Eight isolates of the species Heterorhabditis amazonensis were evaluated on field-collected and laboratory-reared insect populations. The isolates that performed best in the virulence test were evaluated for in vivo production on Galleria mellonella Fabricius larvae. Then, these were evaluated in field conditions on E. heros from the laboratory and field populations. The isolates IBCB-n46, NEPET11, and IBCB-n40 caused the highest mortality in adult E. heros from laboratory rearing (100, 94, and 80%, respectively), and IBCB-n46 and NEPET11 were the best against the field population (71 and 47% mortality, respectively). In the assay to evaluate production, the isolate IBCB-n46 achieved the best result (3.4 × 105 IJs/g per larvae), followed by isolates UEPN05 (1.4 × 105 IJs/g per larvae) finally NEPET11 (7.5 × 104 IJs/g per larvae). In the assay in field conditions, all treatments differed from the control treatment, no significant differences were observed in the evaluated factors (isolates and insect populations), and the highest percentage of mortality was obtained by the UEPN05 isolate when applied to insects from the laboratory (18.57% mortality).

Breastfeeding and diseases prevalent in the first two years of a child's life: a cross-sectional study / Lactancia materna y enfermedades prevalentes en los dos primeros años de vida del niño: un estudio transversal / Amamentação e as doenças prevalentes nos primeiros dois anos de vida da criança: estudo transversal

ABSTRACT Objectives: to assess the association between breastfeeding and diseases prevalent in the first two years of a child's life. Methods: a retrospective cross-sectional study that analyzed electronic medical records of 401 children. Data on birth, growth, breastfeeding and medical care in the first two years of life were collected. In the analysis, Poisson regression with robust variance was used. Results: 27.9% of children were exclusively breastfed until six months, and, at 24 months, 93.3% had already had some prevalent childhood disease. In the crude analysis, 5-minute Apgar association, length, weight at 12 months, exclusive and non-exclusive breastfeeding time had association. In the adjusted analysis, only the variable breastfeeding at six months maintained the association with prevalent childhood diseases. Conclusions: children who were not breastfed, exclusively or not, up to six months of age, had a higher prevalence of diseases compared to breastfed children.

ABSTRACT Introduction: The World Health Organization states that prevalent childhood diseases in 2016 caused a mortality of 5 million in children under 5 years old, due to pneumonia and acute diarrheal disease. Objective: Examine modifiable risk factors for prevalent childhood diseases in traditional community welfare homes in Cucuta, Colombia. Methods: An observational, descriptive, cross-sectional study was conducted in 2018 in 23 households of the Colombian Institute of Family Welfare in Cúcuta; the information was collected from the instrument to identify risk factors for prevalent childhood diseases after initial testing. Results: 276 children were attended, 56.8% of them were boys. Modifiable risk factors were identified in homes; in 22,0% of these, children should improve hand washing; with a similar percentage, it was shown that the cleaning of teaching materials, toys, fans and curtains should be insisted upon; in 17.3% regular infrastructure conditions were observed. In addition, 20,0% of the children shared food, there were children with ongoing diseases and absence of care protocols to follow in such cases, among others. Conclusions: The risk factors can be intervened through the strategy of integrated care for prevalent childhood diseases from its clinical, community and local organization components for its prevention, with the interest and understanding of the shared responsibility for the care of this health problem.

Relative Contribution of Windbreak, Copper Sprays, and Leafminer Control for Citrus Canker Management and Prevention of Crop Loss in Sweet Orange Trees.

The management of citrus canker, caused by Xanthomonas citri subsp. citri, has been widely studied in endemic areas because of the importance of the disease in several citrus-producing countries. A set of control measures is well established, but no study has investigated the efficiency of each measure individually and their combination for disease suppression. This study comprised a 3-year field study to assess the relative contribution of three measures for the control of citrus canker and reduction of crop losses. Windbreak (Wb), copper sprays (Cu), and leafminer control (Lc) were assessed in eight different combinations in a split-split plot design. The orchard was composed of 'Valencia' sweet orange trees grafted onto 'Rangpur' lime. Casuarina cunninghamiana trees were used as Wb. Cu and Lc sprays were performed every 21 days throughout the year. Individually, Cu showed the highest contribution for canker control, followed by Wb. Lc had no effect on reducing citrus canker. Wb+Cu showed the highest efficiency for control of the disease. This combination reduced the incidence of diseased trees by approximately 60%, and the incidence of diseased leaves and fruit by ≥90% and increased the yield in 2.0- to 2.6-fold in comparison with the unmanaged plots. Cu sprays were important for reducing disease incidence and crop losses, whereas Wb had an additional contribution in minimizing the incidence of cankered, non-marketable fruit. The results indicated that the adoption of these measures of control may depend on the characteristics of the orchard and destination of the production.

Spectral detection of nematodes in soybean at flowering growth stage using unmanned aerial vehicles / Detecção espectral de nematóides na soja em estádio de florescimento por meio de veículos aéreos não-tripulados

Soybean is one of the main crop species grown in the world. However, there is a decline in productivity due to the various types of stress, including the nematodes Heterodera glycines and Pratylenchus brachyurus. The objectives were to determine the best spectral band for detecting H. glycines and P. brachyurus at the beginning of flowering (R1). Soil and root sampling was conducted at nine sampling sites in each of the five nematode-infested regions, totaling 45 sampling points. Flights were made at all regions using Phantom 4 Advanced, Sequoia and 14-band customized Sentera. For H. glycines, the red spectral band best explained the variability on soil and root nematode counts as well as the second stage of juveniles in soil. For P. brachyurus, Sentera RedEdge best explained the variability in root nematode counts and Sequoia NIR best explained soil juveniles. A multiple linear regression model using spectral data for detecting P. brachyurus and H. glycines improved R² compared to simple linear regressions. At flowering growth stage (R1), soybean spectral reflectance was associated with the number of H. glycines and P. brachyurus on soil and roots using low-cost and multispectral sensors.(AU)

A soja é uma das principais espécies de planta cultivadas no mundo. Todavia, perdas de produtividade são ocasionadas por vários tipos de estresses, incluindo os nematoides H. glycines e P. brachyurus. Como objetivo, buscou-se determinar a melhor banda espectral para a detecção do H. glycines e P. brachyurus com o uso de modelos de regressões lineares simples e definir um modelo matemático de regressão linear múltiplo para sua detecção, no início do florescimento (R1). Para isto, foram definidos nove pontos de coleta em cinco reboleiras, totalizando 45 pontos. As coletas foram feitas em um padrão específico de distâncias, de forma a ter amostras com tipos variados de populações de nematoides. Foram realizados voos com o Phantom 4 Advanced, Sequoia e Sentera sobre cada uma das reboleiras. O comprimento de onda do vermelho melhor explicou a variabilidade dos dados para H. glycines no solo e na raiz, bem como dos juvenis de segundo estádio no solo. Para P. brachyurus, a RedEdge da Sentera foi a que explicou melhor a variabilidade dos dados para nematoide na raiz e a NIR da Sequoia a que melhor explicou para juvenis no solo. Quando se utilizou um modelo matemático para a detecção do P. brachyurus e H. glycines, percebe-se uma grande melhora no R² e p-valor com relação às regressões lineares simples. No início da floração (R1), a refletância espectral da soja foi associada ao número de H. glycines e P. brachyurus no solo e nas raízes, usando sensores de baixo custo e multiespectrais.(AU)

Apoio institucional para agentes comunitários de saúde usando o programa de Atenção Integrada às Doenças Prevalentes na Infância em Ruanda / Institutional support to community health workers using integrated management of childhood illness program in Rwanda

O objetivo foi explorar o apoio e descrever a supervisão de agentes comunitários de saúde que implementam o programa de atenção integrada às doenças prevalentes na infância (AIDPI). Um desenho não experimental, exploratório, descritivo e quantitativo foi adotado neste estudo. Os dados foram coletados entre 305 participantes (30% da população) por meio de um questionário estruturado. Dupla digitação foi utilizada e os dados foram limpos e analisados usando o Statistics Package of Social Sciences (SPSS) 19. Em Ruanda, o apoio e supervisão são fornecidos pela instituição base e supervisores. Os agentes comunitários de saúde (ACS) frequentemente enfrentam escassez de medicamentos e equipamentos (63,3%) e 87,5% ficaram sem equipamentos, medicamentos e consumíveis, o que criou barreiras para a assistência das crianças doentes. Para melhorar o apoio institucional dado aos agentes comunitários de saúde, supervisão de apoio contínua e regular, além do fornecimento de suprimentos, é essencial.

The objective was to explore the support given to community health workers who use the integrated management of childhood illness (IMCI) approach and describe the supervision given to them. A non-experimental, exploratory, descriptive, quantitative design was used for this study. Data were collected using a structured questionnaire; 305 were interviewed (30% sample). The data were double entered, cleaned, and analyzed using Statistics Package of Social Sciences (SPSS) 19. Support and supervision in Rwanda are provided by the base institution and by supervisors. CHWs often had a shortage of drugs and equipment (63.3%) and 87.5% have experienced run out of equipment, medicines, and consumables. This created barriers to caring for sick children. To improve institutional support for community health workers, regular and continuous supportive supervision and supplies are essential.

No início da floração (R1), a refletância espectral da soja foi associada ao número de H. glycines e P. brachyurus no solo e nas raízes, usando sensores de baixo custo e multiespectrais.

La práctica pedagógica en la atención integrada de las enfermedades prevalentes de la infancia desde la perspectiva de Basil Bernstein / Pedagogical practice in the integrated management of prevalent childhood illness from the perspective of Basil Bernstein / A prática pedagógica na atenção integrada das doenças prevalentes da infância da perspectiva de Basil Bernstein

Resumen La estrategia "Atención integrada de las enfermedades prevalentes de la infancia" (aiepi) es reconocida por las entidades de salud internacionales y nacionales como una estrategia que impacta la salud de la población infantil y que sus componentes clínico y comunitario desarrollan la educación para la salud. Objetivo: Comprender cómo se desarrolla la práctica pedagógica en la consulta médica atendida bajo la estrategia aiepi, en una institución de primer nivel de atención durante el año 2015. Metodología: Investigación cualitativa, con una perspectiva hermenéutica. Para la comprensión de la construcción social de la práctica pedagógica se tuvo una orientación etnográfica y el sistema de reglas (jerarquía, secuencia y criterio) propuesto por Bernstein. Las técnicas etnográficas utilizadas fueron entrevista cualitativa, observación participante y entrevista grupal. Se entrevistó a once cuidadores y tres médicas. Resultados: Para las médicas, muchas de las enfermedades son "autolimitadas", se resuelven solas. El propósito de la educación es convencer a los cuidadores de que la información suministrada por las médicas es verdadera. Los temas en educación son determinados por las médicas y centrados en la enfermedad. Para los cuidadores, la médica es referente de conocimiento. Las médicas reconocen que hay saber popular que se estudia y se acepta por el conocimiento científico; sin embargo, solo el conocimiento científico es válido. Conclusión: En la atención de aiepi, la práctica pedagógica es visible, porque se centra en el desempeño del cuidador y en la cantidad de texto que él aprende mediante la repetición, y las médicas ejercen poder sobre los cuidadores, al poseer el conocimiento hegemónico (válido y verdadero) que refuerza el modelo biomédico en la práctica pedagógica.

Abstract The strategy "Integrated Management of Childhood Illness"(IMCI) is recognized by international and national health bodies as a strategy that affects the health of the child population and whose clinical and community components develop health education. Objective: To understand how pedagogical practice develops in medical consultation attended under the IMCI strategy, in a first level care institution in 2015. Methodology: Qualitative research, with a hermeneutic perspective. To understand the social construction of pedagogic practice an ethnographic stance and the system of rules (hierarchy, sequence and criterion) proposed by Bernstein were adopted. The ethnographic techniques used were qualitative interview, participant observation and group interview. Eleven caregivers and three doctors were interviewed. Results: For the doctors, many of the diseases are "self-limiting", i.e. they resolve on their own. The purpose of education is to convince the caregivers that the information provided by the doctors is true. The education topics are determined by the doctors and focused on the disease. For the caregivers, the doctor is a reference of knowledge. The doctors recognize that there is popular knowledge that is studied and accepted by scientific knowledge; however, only scientific knowledge is valid. Conclusion: Pedagogical practice is visible in IMCI care because it focuses on the performance of the caregiver and the amount of text that he learns through repetition, and the doctors exert power over caregivers, as they possess hegemonic (valid and true) knowledge that reinforces the biomedical model in pedagogical practice..

Resumo A estratégia "Atenção integrada das doenças prevalecentes da infância" (AIEPI), é reconhecida pelas entidades de saúde nacionais e internacionais como uma estratégia que impacta a saúde da população infantil e que seus componentes clínicos e comunitários desenvolvem a educação para a saúde. Objetivo: Compreender como se desenvolve a prática pedagógica na consulta médica atendida sob a estratégia AIEPI, numa instituição de primeira linha de atenção durante o ano de 2015. Metodologia: Pesquisa qualitativa com uma perspectiva hermenêutica. Para a compreensão da construção social da prática pedagógica se teve uma orientação etnográfica e o sistema de regras (hierarquia, sequência e critério) proposto por Bernstein. As técnicas etnográficas usadas foram: entrevista qualitativa, observação participante e entrevista grupal. Foram entrevistados 11 cuidadores e 3 médicas. Resultados: De acordo com as médicas, muitas das doenças são "autolimitadas", se curam sozinhas. O objetivo da educação é convencer os cuidadores de que a informação fornecida pelas médicas é verídica. Os temas relacionados à educação são determinados pelas médicas e focados nas doenças. Para os cuidadores, a médica é um referencial de conhecimento. As médicas reconhecem que existe um conhecimento popular que é estudado e aceito pelo conhecimento científico; porém, só o conhecimento científico é válido. Conclusão: No que se refere à atenção de AIEPI, a prática pedagógica é visível, porque está centralizada no desempenho do cuidador e na quantidade de informação escrita que ele aprende através da repetição e as médicas influenciam os cuidadores já que possuem o conhecimento hegemônico (válido e verídico) que reforça o modelo biomédico na prática pedagógica.

Effects of toxic baits and food-based attractants for fruit flies on the parasitoid Fopius arisanus (Sonan) (Hymenoptera: Braconidae).

This study aimed to evaluate the effects of toxic baits and attractants for fruit flies on the biology of its parasitoid Fopius arisanus. We tested two food-based attractants; hydrolysed corn protein (Biofruit® 3%) and sugarcane molasses (7%), their mixtures with spinosad and malathion-based insecticides, and a ready-to-use commercial bait (Success 0.02 CB®). Malathion-based lures were used as references for mortality (i.e., positive control), while negative control was honey. The formulations Biofruit® + malathion (T1), molasses + malathion (T2), and spinosad + molasses (T3) were toxic to F. arisanus, being classified as harmful (class 4). In addition, toxic baits composed of Biofruit + spinosad (T4) reduced parasitism by 97.99%, being rated as moderately harmful (class 3). Yet, Success 0.02 CB® (T7) was considered slightly toxic (class 2), causing a 64.55% reduction in parasitism. Regarding the biological parameters of F. arisanus, offspring number and parasitoid longevity were significantly reduced by using hydrolysed protein attractants when compared to the control (honey). However, sugarcane molasses improved parasitoid reproduction and longevity, as did the honey. Lastly, ingestion tests showed the major role of attractants in toxic-bait formulations against F. arisanus.
