ABSTRACT In-depth knowledge of total soil organic phosphorus (TPO) as a potential P source for plants allows for a comprehensive understanding of the adoption of an efficient management system of phosphorus fertilization in forest plantations. Thus, we aimed to compare three TPO extraction methods (Hedley; Bowman; Bowman and Moir) in different Eucalyptus plantations on strongly weathered soils. The TPO concentrations obtained by the “Hedley” (mean of 130 mg kg–1), and “Bowman and Moir” methods (mean of 131 mg kg–1) were similar. The “Bowman” method extracted less than 50 % of the TPO content extracted by the other methods. Both “Hedley” and “Bowman and Moir” methods showed similar TPO extraction efficiency compared to TP determined by acid digestion. However, the “Hedley” method is the most expensive and time-consuming analytical technique. In view of this, the NaOH+Na2EDTA extractor (Bowman and Moir) would be the most suitable since, in addition to showing high extraction efficiency, it offers fast analysis execution, low analytical error, and lower cost.

RESUMEN Introducción: Más de dos millones de personas en el mundo reciben tratamiento sustitutivo renal; la infección sanguínea representa una amenaza significativa, siendo la segunda causa de muerte en estos pacientes. La tasa de supervivencia depende en gran medida del tipo de acceso vascular utilizado. Objetivo: Determinar las complicaciones en pacientes con catéter de hemodiálisis en relación al sitio de inserción. Materiales y Métodos: Estudio de cohorte prospectivo, analítico, con medición de la frecuencia de complicaciones de pacientes con catéter de hemodiálisis a nivel yugular y femoral. Las variables se obtuvieron de los expedientes clínicos de pacientes internados ≥18 años. Resultados: Se incluyeron 203 pacientes, 66,01% masculinos; una edad media de 52 ± 15 años. 123 pacientes portaban catéter yugular y 80 pacientes, femoral. La curación se realizó cada 3 ± 5 días. La duración media de catéteres antes de signos de infección fue 4 ± 4 semanas en femorales y 9 ± 12 semanas en yugulares. Las bacterias gram positivas predominaron en los hemocultivos; aquellos con acceso femoral presentaron bacteriemia en mayor porcentaje. El cultivo de punta de catéter presentó una baja sensibilidad. Pacientes con catéter femoral presentaron mayor frecuencia de complicaciones. De las complicaciones infecciosas, la más frecuente fue el choque séptico en los portadores de catéteres femorales 57,50% vs los yugulares 4,88%. Otros: endocarditis, 7,32% en yugulares vs 2,50% en femorales; y finalmente la espondilodiscitis, con un 7,50% en femorales. La mortalidad fue mayor en aquellos con catéter femoral, 35% vs 8,94% en yugulares. Conclusión: Se ha evidenciado que el catéter femoral presenta mayor incidencia de complicaciones como choque séptico y bacteriemia, directamente relacionado con mayor tasa de mortalidad.

ABSTRACT Introduction: More than two million people in the world receive renal replacement treatment; Blood infection represents a significant threat, being the second cause of death in these patients. The survival rate depends largely on the type of vascular access used. Objective: Determine complications in patients with hemodialysis catheter in relation to the insertion site. Materials and Methods: Prospective, analytical cohort study, measuring the frequency of complications in patients with hemodialysis catheters at the jugular and femoral levels. The variables were obtained from the clinical records of hospitalized patients ≥18 years of age. Results: 203 patients were included, 66.01% male; an average age of 52 ± 15 years. 123 patients had a jugular catheter and 80 patients had a femoral catheter. Healing was carried out every 3 ± 5 days. The mean duration of catheters before signs of infection was 4 ± 4 weeks in femoral and 9 ± 12 weeks in jugular. Gram-positive bacteria predominated in blood cultures; those with femoral access had bacteremia in a higher percentage. Catheter tip culture had low sensitivity. Patients with a femoral catheter had a higher frequency of complications. Of the infectious complications, the most frequent was septic shock in those with femoral catheters 57.50% vs jugular catheters 4.88%. Others: endocarditis, 7.32% in jugular vs 2.50% in femoral; and finally spondylodiscitis, with 7.50% in femoral bones. Mortality was higher in those with a femoral catheter, 35% vs. 8.94% in jugular catheters. Conclusion: It has been shown that the femoral catheter has a higher incidence of complications such as septic shock and bacteremia, directly related to a higher mortality rate.

ABSTRACT. Emulsifiers in animal diets are an interesting and effective strategy for nutritionists to improve the digestion of dietary lipids and, consequently, provide better performance. This study aimed to evaluate the effect of the supplementation of diets with emulsifier based on mono- and diglycerides (120 g t-1 of feed) associated with different energy levels (2,775; 2,725; 2,675 and 2,625 kcal of metabolizable energy kg-1 of feed) on performance and egg quality of Hisex Brown laying hens. The laying hens were distributed in 50 experimental plots with eight birds each. A completely randomized design with five treatments and ten replicates/treatments was used. The treatments in this study were: control diet (C) with 2,775 kcal of metabolizable energy (ME) kg-1 of feed; C + E: diet C supplemented with an emulsifier (E) at 120 g t-1 of feed; diet C with reduction of 50 kcal ME and supplemented with E (NC50 + E); diet C with reduction of 100 kcal ME and supplemented with E (NC100 + E); and diet C with reduction of 150 kcal ME and supplemented with E (NC150 + E). All diets had the same inclusion level of degummed soybean oil (2%). There was no influence of the treatments on the performance and quality of the eggs (p >0.05). The current study has shown that diets supplemented with emulsifiers based on mono- and diglycerides (120 g t-1) allows reducing the metabolizable energy level up to 150 kcal kg-1 of feed, without impairment on performance and egg quality of Hisex Brown laying hens.

The objectives were to estimate hepatitis A virus seroprevalence in subjects attending to a travel medicine and immunization clinic in Rio de Janeiro, Brazil, and to develop a prediction model for hepatitis A virus seroprevalence. This retrospective research included individuals sequentially from April 2011 to June 2019 at a travel medicine and special population immunization clinic with an anti-hepatitis A virus IgG chemiluminescence result. Participants’ data were verified via electronic medical records. Data were split into development and validation set taking 2018 as the date break. A cross-validated elastic generalized linear model with binomial distribution was performed. In total, 2,944 subjects were analyzed. Hepatitis A virus overall seroprevalence was 67.8%. Health professionals, travelers, and those who had contact with immunocompromised subjects had lower seroprevalence (40%-55%), whereas subjects with chronic conditions (heart, lung, and liver) ranged from 89% to 94%. The retained predictors in the final model were sex, age, year of birth, travelers, HIV/AIDS, spleen dysfunction, transplant candidates, household communicators, cancer-related immunosuppression, health care professionals. Area under the curve was 0.836 and maximum error was 0.051. Users can make predictions with the following calculator: https://pedrobrasil.shinyapps.io/INDWELL/. The groups with lower seroprevalence should be evaluated more carefully regarding need for hepatitis A virus vaccination even when they seek immunization clinics for other purposes.

Abstract Background Atrial fibrillation (AF) is the most common arrhythmia in patients with end-stage renal disease (ESRD). The coexistence of high thromboembolic and hemorrhagic risks, added to the lack of strong scientific evidence on the safety of anticoagulants in the setting of renal failure, makes this a clinically challenging situation. Objectives To describe the clinical-demographic profile and prevalence of AF in the population with ESRD undergoing dialysis. Secondary objectives include the assessment of thromboembolic (CHA2DS2VASC) and bleeding (HASBLED) risk scores. Methods Cross-sectional analytical-descriptive study, carried out between January and March 2020. Patients with ESRD were evaluated by means of a medical history questionnaire, physical examination, and 12-lead electrocardiogram. A chi-square (χ2) association test was applied to calculate association between clinical variables and AF, with a significance level of α = 0.05. Results This study evaluated 295 patients, most of whom were men (170), elderly (63, IQR 53-71), current smokers (130), with associated cardio-endocrine comorbidities. The prevalence of AF was 6.7% (20). Heart failure (HF) (χ2=15.417; p<0.001), age of 65 years or older (χ2=14.584; p<0.001), and anticoagulation (χ2=5.715; p<0.01) were associated with AF. The median CHA2DS2VASC and HASBLED was 4 and 3, respectively. Eight patients were taking warfarin and five were receiving apixaban. Conclusion The prevalence of AF in this study is similar to that reported in other published articles on the subject, and patients were at high risk for cardiovascular outcomes. Non-anticoagulation strategy was commonly adopted due to controversies in the literature as well as the absence of published randomized clinical trials.

ABSTRACT Background: The aim of this research was to investigate the efficiency of methods to overcome primary dormancy and biochemical processes associated with germination of Erythrina falcata Benth seeds. Seeds were submitted to dormancy overcoming treatments and the water uptake pattern was analysed. We then evaluated the activity of the antioxidant enzymes SOD, CAT, and APX, and quantified lipid peroxidation levels, hydrogen peroxide content and total protein content. The experiments were performed in a completely randomized design and the statistical analysis used was Scott-Knott test at 5% probability. Results: Mechanical scarification with sandpaper leads to approximately 94% of germination in E. falcata, while control non-scarified seeds show only approximately 37% of germination. Treatments with hot water led to high mortality in E. falcata seeds. Rapid water absorption was observed in the first 18 hours of imbition when the seeds were scarified with sandpaper, and radicle emergence was observed after 36 hours. During imbibition there was an increase of antioxidant enzyme activity and a decrease in lipid peroxidation and H2O2 production, suggesting an efficient mechanism for regulating imbibition damage. A decrease in the total protein content was observed during germination of E. falcata seeds. Conclusions: Mechanical scarification is an efficient method for breaking dormancy of E. falcata seeds. During germination of E. falcata seeds there is a reduction in the production of H2O2 and lipid peroxidation, and an increase in the activity of antioxidant enzymes. The total protein content decreased along the germination time.

Abstract The objective of this work was to compare nitrous oxide (N2O) emissions from urine and manure of Nellore and crossbred (Nellore x Angus) cattle finished in feedlot. Twenty Nellore and 20 crossbred bulls were fed a diet consisting of 75% concentrate and 25% roughage. Excreta were applied to the pens after 43 days of confinement, when N2O monitoring started through static chambers. The data were subjected to the analysis of variance, and averages were compared by Tukey’s test. The N2O fluxes from urine and manure were similar among the breeds, with important peaks after rain events. The cumulative emissions of N2O from urine per kilogram of body weight gain (BWG) and the total emissions from manure per kilogram of BWG were 22.7% and 24.4% higher in Nellore cattle. There is no breed effect on N2O flux and cumulative emissions by excreta from confined beef cattle; however, the crossbreed emits less per kilogram of BWG. There is a high correlation between rainfall volume and the N2O emissions of the next day, which indicates a period between rain occurrence and the increase in N2O emission.

Resumo O objetivo deste trabalho foi comparar as emissões de óxido nitroso (N2O) pela urina e pelas fezes de bovinos Nelore e mestiços (Nelore x Angus) terminados em confinamento. Vinte bois Nelore e 20 mestiços foram alimentados com dieta composta de 75% de concentrado e 25% de volumoso. As excretas foram aplicadas nos currais após 43 dias de confinamento, quando se iniciou o monitoramento de N2O por meio de câmaras estáticas. Os dados foram submetidos à análise de variância, e as médias foram comparadas pelo teste de Tukey. Os fluxos de N2O da urina e das fezes foram semelhantes entre as raças, com picos importantes após a ocorrência de chuvas. As emissões cumulativas de N2O da urina por quilograma de ganho de peso corporal (GPC) e as emissões totais das fezes por quilograma de GPC foram 22,7% e 24,4% maiores na raça Nelore. Não há efeito da raça sobre o fluxo de N2O e as emissões cumulativas de excretas de bovinos de corte confinados; entretanto, o gado mestiço emite menos por quilograma de GPC. Há alta correlação entre o volume de chuva e as emissões de N2O do dia seguinte, o que indica um período entre a ocorrência de chuva e o aumento da emissão de N2O.

ABSTRACT We present novelties on the occurrence of species belonging to the tribes Marcetieae, Melastomateae and Pyxidantheae (Melastomataceae) derived from revision of herbarium material and recent collections in the Brazilian Amazon. We report the rediscovery of the type species of Comolia, known only from the original material, the first records of Appendicularia, Dicrananthera and Blakea in the states of Pará, Roraima and Rondônia, respectively, and the first record of Pterogastra in Brazil. We provide maps with the updated geographical distribution for each species based on the revision of herbarium collections available in online databases followed by manual data cleaning. Geographic location coordinates were obtained after reviewing the identities and locality information of all herbarium specimens. Most distribution records result from recent botanical expeditions within protected areas in the Brazilian Amazon. The first records of Pterogastra in Brazil expand the diversity of Melastomataceae in Brazilian flora to 59 genera. These novelties reinforce the importance of botanical expeditions throughout the Brazilian Amazon to cover the extensive spatial gaps in taxonomic knowledge in the region which should be prioritized as the focus of botanical fieldwork.

RESUMO Apresentamos novidades na ocorrência de espécies pertencentes às tribos Marcetieae, Melastomateae e Pyxidantheae (Melastomataceae) derivadas da revisão de material de herbário e coleções recentes na Amazônia brasileira. Relatamos a redescoberta da espécie-tipo de Comolia, conhecida apenas a partir do material original, os primeiros registros de Appendicularia, Dicrananthera e Blakea nos estados do Pará, Roraima e Rondônia, respectivamente, e o primeiro registro de Pterogastra no Brasil. Fornecemos mapas com a distribuição geográfica atualizada de cada espécie com base na revisão das coleções de herbários disponíveis em bases de dados online, seguido de limpeza manual dos dados. As coordenadas de localização geográfica foram obtidas após revisão das identidades e informações de localidade de todos os espécimes do herbário. A maioria dos registros de distribuição resulta de expedições botânicas recentes em áreas protegidas na Amazônia brasileira. Os primeiros registros de Pterogastra no Brasil ampliam a diversidade de Melastomataceae na flora brasileira para 59 gêneros. Essas novidades reforçam a importância das expedições botânicas por toda a Amazônia brasileira para cobrir as extensas lacunas espaciais do conhecimento taxonômico na região que deve ser priorizada como foco do trabalho de campo botânico.

Abstract The objective of this work was to evaluate the effects of increasing rates of biochar produced with coffee straw, at two pyrolysis temperatures, on the chemical attributes of an Oxisol cultivated with conilon coffee (Coffea canephora) and on the nutrient content of coffee tree leaves. Treatments consisted of pyrolysis at two temperatures (350 and 600 °C) and of five biochar rates (0, 5, 10, 15, and 20 Mg ha-1). The following soil chemical attributes were evaluated: pH in water; P, K, Ca, Mg, Al, H+Al, Zn, Cu, Fe, and Mn contents; effective and potential cation exchange capacity (CEC); sum of bases (SB); base (V) and aluminium (m) saturation; and N, P, K, Ca, Mg, Zn, Cu, Fe, and Mn contents in the leaves. The biochar produced at 600°C, at rates of 10 and 15 Mg ha-1, promoted a greater K release into the soil. Regardless of temperature, coffee straw biochar increased K and P availability, sum of bases, base saturation, and CEC in the soil, but did not influence macro- and micronutrient contents in the leaves. The addition of increasing rates of coffee straw biochar in the soil increases P, K, Mg, SB, CEC, and V, regardless of pyrolysis temperature.

Resumo O objetivo deste trabalho foi avaliar os efeitos de doses crescentes de biocarvão produzido com palhada de café, em duas temperaturas de pirólise, nos atributos químicos de um Latossolo cultivado com cafeeiro conilon (Coffea canephora), e no conteúdo de nutrientes das folhas do cafeeiro. Os tratamentos consistiram de duas temperaturas de pirólise (350 e 600°C) e cinco doses de biocarvão (0, 5, 10, 15 e 20 Mg ha-1). Avaliaram-se os seguintes atributos químicos do solo: pH em água; teores de P, K, Ca, Mg, Al, H+Al, Zn, Cu, Fe e Mn; capacidade de troca catiônica efetiva e potencial (CTC); soma de bases (SB); saturação por bases (V) e por alumínio (m); e teores de N, P, K, Ca, Mg, Zn, Cu, Fe e Mn nas folhas. O biocarvão produzido a 600°C, nas doses de 10 e 15 Mg ha-1, promoveu maior liberação de K ao solo. Independentemente da temperatura, o biocarvão promoveu o aumento de P e K disponíveis, SB, V e CTC no solo, mas não influenciou os conteúdos dos macro e micronutrientes das folhas. A adição de doses crescentes de biocarvão da palha de café conilon no solo promove aumento de P, K, Mg, SB, CTC e V, independentemente da temperatura de pirólise.

Abstract The Brazilian Society of Angiology and Vascular Surgery, through the Guidelines Project, presents new Abdominal Aortic Aneurysm Guidelines, on the subject of care for abdominal aortic aneurysm patients. Its development prioritized descriptive guidelines, using the EMBASE, LILACS, and PubMed databases. References include randomized controlled trials, systematic reviews, meta-analyses, and cohort studies. Quality of evidence was evaluated by a pair of coordinators, aided by the RoB 2 Cochrane tool and the Newcastle Ottawa Scale forms. The subjects include juxtarenal aneurysms, infected aneurysms, and new therapeutic techniques, especially endovascular procedures. The current version of the guidelines include important recommendations for the primary topics involving diagnosis, treatment, and follow-up for abdominal aortic aneurysm patients, providing an objective guide for medical practice, based on scientific evidence and widely available throughout Brazil.

Resumo A Sociedade Brasileira de Angiologia e Cirurgia Vascular, por meio do projeto Diretrizes, apresenta as novas Diretrizes de Aorta Abdominal, referentes aos cuidados de pacientes com aneurisma de aorta abdominal. Para sua elaboração, foram priorizadas diretrizes descritivas, utilizando as bases EMBASE, LILACS e PubMed. As referências incluem ensaios clínicos randomizados, revisões sistemáticas, metanálises e estudos de coorte. A qualidade das evidências foi examinada por uma dupla de coordenadores, com auxílio da ferramenta RoB 2 da Colaboração Cochrane e dos formulários da Newcastle Ottawa Scale. Aneurismas justarrenais, infectados e novas técnicas terapêuticas, principalmente no âmbito endovascular, estão entre os temas estudados. A versão atual das Diretrizes apresenta importantes recomendações para os principais itens que envolvem o diagnóstico, tratamento e acompanhamento de pacientes com aneurisma de aorta abdominal, oferecendo um guia objetivo para prática médica, construído a partir de evidências científicas e amplamente acessível em todo o território nacional.

Resumo Foi instalado um ensaio de campo junto ao rio Gévora (“Las Vegas Bajas de Guadiana”, Extremadura, Espanha), durante 3 anos, para avaliar a influência da aplicação de composto de resíduos da produção de azeite (bagaço de azeitona ou 'Alperujo'), e de diferentes sistemas de rega, na acumulação de As e Cd no arroz. A rega deficitária (aspersão) levou a uma diminuição na acumulação de As no grão, quando comparada com a rega por inundação, atingindo concentrações de As no grão nos tratamentos aeróbios mais de 5 vezes inferior à atingida nas condições de rega por inundação. A concentração de As no grão, nos tratamentos aeróbios, atingiu valores inferiores ao limite estabelecido pela Comissão Europeia (0.20 mg kg-1 no grão de arroz, peso fresco), e mesmo inferiores ao limite estabelecido para arroz branco polido para utilização em alimentos para bebés (0.10 mg kg-1). Porém, um efeito contrário foi observado na acumulação de Cd no grão, que aumentou nos tratamentos aeróbios. A aplicação de composto (80 t ha-1 no primeiro ano), foi capaz de contrabalançar esse efeito negativo, levando a uma diminuição na acumulação de Cd no grão, em comparação com a produção obtida sem aplicação de composto (e.g., uma diminuição de 0,080 para <0,010 mg Cd kg-1 no grão, em sementeira direta com rega por aspersão), sem aumentar a concentração de As no grão. Por isso, foi possível concluir que, o cultivo aeróbio de arroz, com a aplicação simultânea de um corretivo orgânico maturado e estável, constitui uma boa solução para, simultaneamente, diminuir o risco de acumulação de As e Cd nos grãos de arroz.

Abstract A field experiment was set-up near the Gévora River (“Las Vegas Bajas de Guadiana”, Extremadura, Spain), for 3 years, to evaluate how the application of compost from olive mill waste, influences the accumulation of As and Cd in rice grain under different irrigation systems. The deficit irrigation (sprinkler irrigation) was able to lower the accumulation of As in the grain, when compared to the flooding irrigation systems, achieving As concentrations in the grain more than 5-times lower in the aerobic treatments than in the flooding irrigation conditions. The As concentrations in the aerobic treatments achieved values below the regulated limits established by the European Commision (0.20 mg kg-1 in the rice grain, fresh material), and even below the limit set for white polished rice intended to produce food for infants (0.10 mg kg-1). However, a contrary effect was observed on Cd accumulation in the grain, which increased in the aerobic treataments. Compost application (80 t ha-1 in the first year), was able to counterbalance that negative effect, lowering Cd accumulation in the rice grain, relatively to the non-treated counterparts (e.g., a reduction from 0.080 to <0.010 mg Cd kg-1 in the grain, in direct seeding with sprinkler irrigation), without increasing grain As concentrations. It was possible to conclude that, the aerobic cultivation of rice, with the simultaneous application of a mature and stable organic amendment, can be considered a good solution to, simultaneously, lower the risk of accumulation of As and Cd in the rice grain.

Conclui-se que referente ao perfil sociodemográfico, predomina o sexo feminino dentre as(os) enfermeiras(os) pesquisadas(os), quanto à formação, há necessidade de qualificação em níveis residências e de pós-graduação stricto sensu. Na dimensão assistencial, a consulta de enfermagem no pré-natal, como uma prática resolutiva do cuidado na APS na Paraíba.

ABSTRACT Nursing work involves care and management dimensions, reflected in the production of care actions in the care of individuals, families and communities. The objective was to analyze the Primary Health Care (PHC) nursing work process in Paraíba, considering the professional profile and individual daily practices developed by nurses in the care dimension. A quantitative approach study, carried out at the PHC services in Paraíba between November 2019 and August 2021. The analysis of quantitative data was performed using the SPSS® software (Statistical Package for the Social Sciences), version 21.0 for Windows®, using descriptive and inferential statistical analysis. The results showed, among other aspects, that 93.3% professionals are female; with regard to professional training, specialization was the most common type of degree among the professionals surveyed; among the practices analyzed, prenatal consultations were considered the most resolute, according to the perception of 388 (84%) professionals surveyed. It is concluded that, regarding the sociodemographic profile, the female sex predominates among the nurses surveyed, regarding training, there is a need for qualification at residency and stricto sensu postgraduate levels. In the care dimension, the nursing consultation in prenatal care, as a problem-solving practice of care in PHC in Paraíba.

RESUMO O trabalho de enfermagem envolve as dimensões assistencial e gerencial, refletidas na produção das ações de cuidado na atenção aos indivíduos, famílias e comunidades. Objetivou-se analisar o processo de trabalho de enfermagem da Atenção Primária à Saúde (APS) na Paraíba, considerando-se o perfil profissional e as práticas cotidianas individuais desenvolvidas por enfermeiras(os) na dimensão assistencial. Estudo de abordagem quantitativa, realizado nos serviços da APS na Paraíba entre novembro de 2019 e agosto de 2021. A análise dos dados quantitativos foi feita por meio do software SPSS® (Statistical Package for the Social Sciences), versão 21.0 para Windows®, mediante análise estatística descritiva e inferencial. Os resultados, evidenciaram dentre outros aspectos, que 93,3% dos profissionais são do sexo feminino; no que se refere à formação profissional, a especialização foi a modalidade de titulação mais realizada pelos profissionais pesquisados; dentre as práticas analisadas, a consultas pré-natal foi considerada a mais resolutiva, na percepção de 388 (84%) profissionais pesquisados. Conclui-se que referente ao perfil sociodemográfico, predomina o sexo feminino dentre as(os) enfermeiras(os) pesquisadas(os), quanto à formação, há necessidade de qualificação em níveis residências e de pós-graduação stricto sensu. Na dimensão assistencial, a consulta de enfermagem no pré-natal, como uma prática resolutiva do cuidado na APS na Paraíba.

Resumen Mejorar las técnicas para criar depredadores en el laboratorio, incluida la edad de apareamiento, es importante para obtener el mayor número de individuos para los programas de control biológico. El objetivo de este trabajo fue evaluar la fecundidad de hembras del depredador Podisus fuscescens (Dallas, 1851) (Hemiptera: Pentatomidae) con diferentes periodos de pre-apareamiento. Los tratamientos fueron: las hembras de este depredador se aparearon inmediatamente después de la emergencia (T1) o con uno (T2), dos (T3), tres (T4), cuatro (T5) o cinco (T6) días después de la emergencia. Las hembras que se aparearon inmediatamente (T1) y un día después de la emergencia (T2) tuvieron menos posturas que las que se aparearon después de cinco días (T6). El número de ninfas por hembra fue menor para las apareadas en emergencia (T1) y uno o dos días después. El número total de huevos fue menor para las hembras apareadas un día después de la emergencia (T2) que para aquellas apareadas después de cinco días (T6). La proporción de huevos eclosionados fue menor en los tratamientos T1 y T2 en comparación con el tratamiento T6. El período de oviposición y la longevidad de las hembras de P. fuscescens fueron similares entre los tratamientos, sin embargo, el período de preoviposición fue más largo para las hembras del tratamiento T1 que para las de T5 y T6 y el período de posoviposición fue más largo en las hembras del tratamiento T1. Las hembras de P. fuscescens necesitan cinco días después de la emergencia para que su sistema reproductivo madure, lo que mejora su aptitud y evita copulaciones innecesarias.

Abstract The improvement of techniques for the mass rearing of predators in the laboratory, including the age of mating is important to obtain the largest number of individuals for biological control programs. The purpose of this study was to evaluate the females’ fecundity of the predator Podisus fuscescens (Dallas, 1851) (Hemiptera: Pentatomidae) with different pre-mating periods. The females of this predator were mated immediately after emergence (T1) or with one (T2), two (T3), three (T4), four (T5) or five (T6) days after emergence. The females mated immediately and one day after the emergency (T1 and T2) had fewer egg clusters than those mated after five days (T6). The number of nymphs per female was lower for those mated immediately after the emergence (T1) and with one (T2) or two days (T3). The total number of eggs was lower in females mated one day after emergence (T2) than for those mated after five days (T6). The proportion of hatched eggs was lower in the treatments T1 and T2 than in the T6. The oviposition and longevity of P. fuscescens females were similar between treatments; however, the pre-oviposition period longer in the T1 than T5 and T6. The pos-oviposition period was longer in the T1. Podisus fuscescens females require five days after emergence to mature their reproductive system, which improves their fitness and avoids unnecessary mating.
