ABSTRACT Callao Bay is strategically important for the industrial and tourist sector, serving as a recreational space for a large part of the population of Chalaca. However, even so, it permanently receives discharges of effluents, chemical products, and residues from oil refineries, hydrocarbons, and domestic and agricultural residues. The objective of this research is to evaluate biochemical indicators in fish against contaminants in the coastal area of Callao, Peru. The seasonal criterion (collections in autumn, spring, summer, and winter) and the spatial criterion (collections at four points along the coastal zone of Callao) were considered. Isacia conceptionis and Odontesthes regia showed relatively high concentration values of the enzyme alanine aminotransferase (ALT). Specifically, ALT is an enzyme used to assess liver function. Sciaena deliciosa showed high levels of alkaline phosphatase (ALP) in the liver but low values of aspartate aminotransferase (AST) and ALT. In addition, ALP is an indicator of renal impairment; in saltwater fish, its increase may be related to the increase in water salinity. The fish with the highest trophic level among the marine fish analyzed was O. regia. This fish presented the lowest values of ALP in the liver and muscle ALP and AChE (acetylcholinesterase) in the liver and the highest values for AST. S. deliciosa and O. regia are species that can be used in environmental biomonitoring, showing variation to the biomarkers studied because they have shown changes in the values of biochemical markers, mainly AChE of the brain and muscle, and in the protein concentrations of muscle, brain, and liver between seasons and sampling points in Callao Bay. It is concluded that the marine fish models evaluated are very useful in assessing contamination in Callao Bay.

Abstract This research aimed to produce and evaluate particleboard with pinus waste using two production methodologies. One applied to homogeneous panels (single layer) and another to heterogeneous panels (three layers). The panels were produced with an initial density of 0.550 g/cm³, with 10% polyurethane resin derived from castor oil (PUR) for the homogeneous panels and 12% for the heterogeneous ones. The pressing parameters were 5 MPa, with a temperature of 100 ºC and 10 min of pressing, with an interval of 30 s. The tests performed according to NBR 14810-2 (ABNT, 2018) standard. As a result, it was observed that the reorganization of the particles of the heterogeneous panels added to the increase of the adhesive were factors that improved the final properties of the panels, which are classified to be used as decoration objects and in the furniture industry, not obtaining classification of homogeneous panels.

Resumo Esta pesquisa teve como objetivo produzir e avaliar painéis aglomerados com resíduo de pinus medianteuma metodologia de produçãoaplicada para painéis homogêneos e outra para heterogêneos. Os painéis homogêneos e heterogêneos foram produzidos com densidade inicial de 0,550 g/cm³ e com 10% e 12% de resina de poliuretano derivado do óleo de mamona (PUR) respectivamente. Os parâmetros de prensagem foram de 5 MPa, com temperatura de 100 ºC e 10 min de prensagem, com um intervalo de 30 s. Os ensaios realizados seguiram a normativa NBR 14810-2 (ABNT, 2018). Observou-se que a reorganização das partículas dos painéis heterogêneos somada ao aumento do adesivo foram fatores que melhoraram as propriedades finais desses painéis, classificados para ser utilizados como objetos de decoração e na indústria moveleira, enquanto os painéis homogêneos não obtiveram classificação.

ABSTRACT The objective of this study was to analyze the feasibility of using thermal images to estimate the water status of melon plants (Cucumis melo L.) in tropical semi-arid climates. The study was conducted in a randomized block design with a split-plot arrangement. The plots comprised of soil cover (with and without mulching), and subplots were constructed using five irrigation regimes (120, 100, 80, 60, and 40% crop evapotranspiration), with five replicates. The following variables were evaluated: canopy temperature (Tcanopy), leaf water potential, air temperature (Tair), soil moisture, crop yield, and thermal index (ΔT), which is defined as the difference between Tcanopy and Tair. ΔT exhibited high correlations with crop yield and water consumption, indicating that thermography is an efficient tool for identifying the water status of melon plants, which could be employed for proper irrigation scheduling under tropical semi-arid scenarios. Moreover, thermal images identified the beneficial effects of soil cover on leaf water status and crop yield, primarily under moderate deficit irrigation. These results demonstrate that mulching is essential for increasing melon yield and water productivity in tropical regions.

RESUMO O objetivo principal deste trabalho foi avaliar o uso de imagens térmicas para estimar o estado hídrico de plantas de meloeiro (Cucumis melo L.) sob clima tropical semiárido. O estudo foi realizado em delineamento de blocos casualizados, em esquema de parcelas subdivididas. As parcelas foram compostas pela cobertura do solo (com e sem cobertura morta) e as subparcelas por cinco regimes de irrigação (120, 100, 80, 60 e 40% da evapotranspiração da cultura - ETc), com cinco repetições. Foram avaliadas as seguintes variáveis: temperatura do dossel (Tdossel), potencial hídrico foliar (Ψfolha), temperatura do ar (Tair), umidade do solo, produtividade da cultura e índice térmico (ΔT), sendo este definido como a diferença entre Tdossel e Tair. O ΔT apresentou altas correlações com a produtividade da cultura e o consumo de água da cultura, evidenciando que a termografia é uma ferramenta eficiente para identificar o estado hídrico das plantas de meloeiro e pode ser empregada para uma adequada programação da irrigação em cenários do semiárido tropical. Além disso, o uso de imagens térmicas também permitiu identificar os efeitos benéficos da cobertura do solo sobre o estado hídrico foliar e a produtividade das culturas, principalmente sob moderado déficit de irrigação (DI). Os resultados obtidos também demonstram que a cobertura morta é essencial para aumentar a produtividade do melão e a produtividade da água em regiões tropicais.

Abstract This work, subdivided into the first part and the second part, produced a technographic overview of the lithic material of middle Holocene sites, located in the central portion of South America, in the macro-region dominated by savannas in the lowlands of South America. This analysis was possible through reflection on available bibliographic information. The description of the modes of making lithic tools was based on the recognition of the three technical principles based on the techno-functional perspective: debitage, shaping and affordance; and on the considerations about relationship between the active and prehensive parts of the pieces (also called “techno-functional categories”). As a result, a synthesis of the technological peculiarities and variabilities was obtained in areas little known or documented with regard to the lithic materiality. In the first part of the article, this overview highlighted that there was, in the groupings of the sites of the Cratón Amazônico, a localized contribution to the relative technical cultures on the part of the principles of debitage and shaping, without being completely homogeneous. In reference to the management of raw materials, a local supply of lithic resources can be seen near these sites.

Resumen Este trabajo, subdividido em primera y segunda parte, presenta un panorama tecnográfico del material lítico proveniente de sitios del Holoceno medio, localizados en la región central de América del Sur, específicamente de la macro-región dominada por sabanas en las tierras bajas. Este análisis fue posible a través de una revisión y reflexión sobre la información bibliográfica disponible. En base a un enfoque tecno-funcional, la descripción de los modos de manufactura de útiles líticos se basó en el reconocimiento de tres principios técnicos desde el punto de vista tecno-funcional: débitage, façonnage y affordance, así como de la consideración de la relación entre las porciones activas y prehensivas de las piezas interpretadas como útiles (denominadas también “categorías tecno- funcionales”). Como resultado se obtuvo una síntesis de las particularidades y variabilidades tecnológicas en áreas poco conocidas o documentadas en lo que se refiere a la materialidad lítica. En la primera parte del artículo, esta síntesis puso en evidencia que en los agrupamientos de los sitios del Cratón Amazónico existió un conjunto de culturas tecnicas relativamente homogéneas concentradas alrededor de los principios de débitage y façonnage. En cuanto a la gestión de la materia prima, se observa en estos sitios un aprovisionamiento local de recursos líticos.

Abstract This article constitutes the second part of the lithic technographic analysis of Middle Holocene sites in a vast macro-region, the central portion of South America: it includes the groups of sites B, C and D. A common element in all the analyzed sets is the presence of the techno-functional category B tools. In reference to the production mode, it is observed that the principle of debitage predominates in the area of analysis. However, its application was diverse; there are assemblages in which there was a predetermination about the making of flakes, others in which the cores were reintroduced as blanks or presented edges and there are other places in which façonnage confection flakes were reintroduced as blanks for tools. Other production principles have also been recorded: the principles of affordance (both in the exclusive productional expression and in its productional and functional expression) and shaping are observed in sites in groups A, C and D. Recognizing the different production modes is the starting point for thinking about how groups with different technical traditions have occupied different spaces in the region.

Resumen Este artículo conforma la segunda parte del análisis de las tecnografías líticas de los sitios del Holoceno medio en una extensa macrorregión, el sector central de América del Sur: abarca los agrupamientos B, C y D de los sitios. Un elemento común en todos los conjuntos analizados en la presencia de herramientas de la categoría tecno-funcional B. En referencia a los modos de producción se observa que el principio de debitagem predomina en el área de análisis. No obstante su aplicación es diversa; hay conjuntos donde existió una predeterminación sobre la confección de lascas, otros donde los núcleos son reintroducidos como soportes o presentando filos y otros sitios en donde se reintrodujeron lascas de confección de façonage como herramientas de soporte. El resto de los principios de producción también fueron registrados: el de afordancia (tanto en la producción instrumental como en su expresión produccional) y el de façonage se observan en sitios de los agrupamientos A, C y D. El reconocimiento de los diferentes modos de producción, es el punto de inicio para pensar como grupos con tradiciones técnicas diferentes, ocuparon espacios diversos en la región.

Abstract Bacteria responsible for causing infections are common in hospital environments, water, soil, and food products. The infection risk is intensified by the absence of public sanitation, poor quality of life, and food scarcity. These external factors promote the dissemination of pathogens by direct contamination or biofilm formation. In this work, we identified bacterial isolates obtained from intensive care units in the southern region of Tocantins, Brazil. We compared matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) techniques and 16S ribosomal ribonucleic acid (rRNA) molecular analysis; we also performed phenotypic characterization. Fifty-six isolates characterized using morphotinctorial tests were classified as gram-positive (80.4%; n = 45) and gram-negative (19.6%; n = 11) and were resistant to several antibiotic classes; notably, we identified the blaOXA-23 resistance gene in the ILH10 isolate. Microbial identification using MALDI-TOF MS resulted in the identification of Sphingomonas paucimobilis and Bacillus circulans. 16S rRNA sequencing revealed four isolates belonging to the genera Bacillus and Acinetobacter. The similarity was superior to 99% for Acinetobacter schindleri in the Basic Local Alignment Search Tool (BLAST), grouped in the clade superior to 90%. Several strains isolated from intensive care units (ICU) were resistant to various antibiotic classes. These techniques allowed for the identification of several microorganisms of importance in public health, enabling improvements in human infection control and proving the quality of inputs, food, and water.

Resumo As bactérias responsáveis por causar infecções são comuns em ambientes hospitalares, água, solo e produtos alimentícios. O risco de infecção é intensificado pela ausência de saneamento público, má qualidade de vida e escassez de alimentos. Esses fatores externos promovem a disseminação de patógenos por contaminação direta ou formação de biofilme. Neste trabalho, identificamos isolados bacterianos obtidos de unidades de terapia intensiva na região sul do Tocantins, Brasil. Comparamos técnicas de espectrometria de massa de tempo de voo com ionização por dessorção a laser assistida por matriz (MALDI-TOF MS) e análise molecular de ácido ribonucleico ribossômico 16S (rRNA); também realizamos caracterização fenotípica. Cinquenta e seis isolados caracterizados por testes morfotintoriais foram classificados como gram-positivos (80,3%; n = 45) e gram-negativos (19,6%; n = 11) e foram resistentes a várias classes de antibióticos; notavelmente, identificamos o gene de resistência blaOXA-23 no isolado de ILH10. A identificação microbiana usando MALDI-TOF MS resultou na identificação de Sphingomonas paucimobilis e Bacillus circulans. O sequenciamento do 16S rRNA revelou quatro isolados pertencentes aos gêneros Bacillus e Acinetobacter. A similaridade foi superior a 99% para Acinetobacter schindleri no BLAST, agrupado no clado superior a 90%. Várias cepas isoladas de ICU foram resistentes a várias classes de antibióticos. Essas técnicas permitiram a identificação de diversos microrganismos de importância em saúde pública, possibilitando melhorias no controle de infecções humanas e comprovando a qualidade dos insumos, alimentos e água.

ABSTRACT Schistosomiasis is a major health problem that affects over 200 million people worldwide. There are few reports of Schistosoma mansoni found in liver transplants as well as scarce information about the course of the disease and the long-term effects on the graft. Herein, we report two cases of schistosomiasis in liver transplant recipients who presented abnormal serum liver enzymes, with evidence of gradual improvement after antiparasitic treatment. Furthermore, we discuss the possible role of screening the parasite infection in potential liver transplant recipients from endemic areas.

Abstract Periodontitis Stage III-IV, Grade C (PerioC) is a severe form of Periodontitis. The individual genetic background has been shown to be an important etiopathogenic factor for the development of this disease in young, systemically healthy, and non-smokers patients. Recently, after exome sequencing of families with a history of the disease, PerioC was associated with three single nucleotide variations (SNVs) – rs142548867 (EEFSEC), rs574301770 (ZNF136), and rs72821893 (KRT25) – which were classified as deleterious or possibly harmful by prediction algorithms. Objective Seeking to validate these findings in a cohort evaluation, this study aims to characterize the allele and genotypic frequency of the SNVs rs142548867, rs574301770, and rs72821893 in the Brazilian population with PerioC and who were periodontally healthy (PH). Methodology Thus, epithelial oral cells from 200 PerioC and 196 PH patients were harvested at three distinct centers at the Brazilian Southern region, their DNA were extracted, and the SNVs rs142548867, rs574301770, rs72821893 were genotyped using 5′-nuclease allelic discrimination assay. Differences in allele and genotype frequencies were analyzed using Fisher’s Exact Test. Only the SNV rs142548867 (C > T) was associated with PerioC. Results The CT genotype was detected more frequently in patients with PerioC when compared with PH subjects (6% and 0.5% respectively), being significantly associated with PerioC (odds ratio 11.76, p=0.02). Conclusion rs142548867 represents a potential risk for the occurrence of this disease in the Brazilian population.

ABSTRACT The composting technique has been increasingly highlighted in poultry production units, as an efficient and low-cost solution for the destination of carcasses. The process is based on the accelerated decomposition of organic material under high temperatures, associated with eliminating pathogenic microorganisms. This study aims to evaluate the effectiveness and the time necessary for the elimination of Salmonella Gallinarum in carcasses of poultry submitted to the composting process. The composting was carried out following the models used in the field, and microbiological analysis was performed in five different periods: 45, 90, 120, 150 and 180-days after closing the composter. After 90 days of experiment and in the subsequent analysis, the elimination of the bacteria in 100% of the samples was verified, validating the composting process as an effective method for eliminating S. Gallinarum in poultry carcasses, when respecting the period necessary for the elimination of the bacteria and the good quality of the structure adopted for the process.

Abstract Understanding the influence of fine-scale abiotic filters on plant communities can provide important insights into floristic patterns of the Brazilian Cerrado. We aimed to evaluate the interactions of the soil and the plant community composition with their distribution in different sandy environments of Brazilian Cerrado, the Jalapão region. Eight environments were sampled, each with ten plots of 20 × 50 m. All woody individuals presenting circumference at soil height ≥ 10 cm were sampled. Subplots of 5 × 15 m were demarcated, where woody individuals with a circumference at soil height ≥ 5 and < 10 cm were sampled. Subplots of 2 × 2 m were also demarcated to sample herbaceous individuals. Soil samples varying from 0 to 20 cm of depth were collected for each plot (20 × 50 m). Overall, 20000 individuals that belong to 338 species and 76 families were sampled. The dominant family was Fabaceae. There were significant differences among the environments regarding species richness and soil. The analyzed soils are extremely poor and with a tendency to sandy texture, small chemical and/or physical variations imply differences in the distribution of vegetation. Our study revealed abiotic filters exerted crucial fine-scale effects on plant community in the Jalapão region.

ABSTRACT In this work we obtain a variational formulation and a priori estimates for approximate solutions of a problem involving fractional diffusion equations.

ABSTRACT Perineal hernia results from weakening and/or the inability of the pelvic diaphragm to support the rectal wall, promoting caudal displacement of abdominal or pelvic organs in the perineum. Unneutered male dogs aged between 7 and 10 years are the most affected, being rare in females. The main clinical signs are unilateral or bilateral swelling of the perineal region, associated or not with tenesmus, dysuria, urinary and/or fecal incontinence, anuria and pain during defecation. The diagnosis is based on clinical history, anamnesis, physical examination, and complementary tests such as radiography and ultrasound. Clinical treatment can be done in some cases, but surgical intervention is required to resolve the problem. The present work aims to report the case of a patient treated at the FullPet Veterinary Clinic in Guarulhos, São Paulo, Brazil, a 7-year-old male Yorkshire canine, unneutered, weighing 4.5 kg. The same was submitted to surgery by the traditional method of suture with nylon thread and enteropexy. When there was recurrence, surgical reintervention was necessary to correct the hernia using a polypropylene mesh.

RESUMEN La hernia perineal resulta del debilitamiento y/o incapacidad del diafragma pélvico para sostener la pared rectal, lo que promueve el desplazamiento caudal de los órganos abdominales o pélvicos en el perineo. Los perros machos no castrados de entre 7 y 10 años son los más afectados, siendo raro en las hembras. Los principales signos clínicos son tumefacción unilateral o bilateral de la región perineal, asociada o no a tenesmo, disuria, incontinencia urinaria y/o fecal, anuria y dolor durante la defecación. El diagnóstico se basa en la historia clínica, la anamnesis, el examen físico y pruebas complementarias como la radiografía simple y la ecografía. El tratamiento clínico se puede hacer en algunos casos, pero se requiere una intervención quirúrgica para resolver el problema. El presente trabajo tiene como objetivo relatar el caso de un paciente atendido en la Clínica Veterinaria FullPet de Guarulhos, São Paulo, Brasil, un canino Yorkshire macho de 7 años, sin castrar, con un peso de 4,5 kg. Fue intervenido quirúrgicamente por el método tradicional de sutura con hilo de nylon y enteropexia. Cuando hubo recidiva, fue necesaria la reintervención quirúrgica para corregir la hernia mediante una malla de polipropileno.

RESUMO A região semiárida apresenta o problema inerente de acúmulo de sais no solo devido ao uso de irrigação com água salobra, e o déficit hídrico que compromete o crescimento e os índices fisiológicos das culturas. Objetivou-se com este trabalho avaliar o efeito do estresse salino e hídrico no crescimento e nas trocas gasosas da cultura da abobrinha cv. Caserta. O trabalho foi realizado em área pertencente à Universidade da Integração Internacional da Lusofonia Afro-Brasileira, Redenção, Ceará, Brasil. O delineamento experimental utilizado foi inteiramente casualizado, em esquema fatorial 5 × 2 com cinco níveis de condutividade elétrica da água de irrigação - CEa (0,5, 1,0, 1,5, 2,0 e 2,5 dS m-1), e dois regimes hídricos (50 e 100% da evapotranspiração potencial da cultura - ETc) com cinco repetições. Aos 36 dias após a semeadura foram avaliadas as variaveis:taxa de assimilação de CO2, transpiração, condutância estomática, concentração interna de carbono, temperatura foliar, índice relativo de clorofila e a eficiência do uso da água. Aos 45 dias após a semeadura, foram avaliadas as seguintes variáveis: altura da planta, diâmetro do caule, número de folhas e área foliar. O uso de água salobra (1 a 2,5 dS m-1) reduz os parâmetros de crescimento da abobrinha cv. Caserta. O aumento da CEa ocasionou redução nas variáveis fisiológicas. A lâmina de 100% proporcionou maiores valores para as variáveis taxa de assimilação de CO2, transpiração, e eficiência instantânea no uso da água, e a lâmina de 50% para concentração interna de carbono, com o aumento da CEa.

ABSTRACT Semi-arid regions present the inherent problem of accumulation of salts in the soil due to the use of brackish water for irrigation, and water deficit compromises the growth and physiological indices of crops. This study evaluated the effect of salt and water stress on growth and gas exchange in the zucchini cv. Caserta crop. The study was conducted at the University of International Integration of Afro-Brazilian Lusophony, Redenção, Ceará State, Brazil. The experimental design was completely randomized, in a 5 × 2 factorial scheme with five levels of electrical conductivity of the irrigation water - ECw (0.5, 1.0, 1.5, 2.0, and 2.5 dS m-1) and two water regimes (50 and 100% of the potential crop evapotranspiration - ETc), with five replicates. At 36 days after sowing, the following traits were evaluated: CO2 assimilation rate, transpiration, stomatal conductance, internal carbon concentration, leaf temperature, relative chlorophyll index, and water use efficiency. At 45 days after sowing, the plant height, stem diameter, number of leaves, and leaf area were also evaluated. The use of brackish water (1 to 2.5 dS m-1) reduced the growth parameters of zucchini cv. Caserta. The increase in ECw caused a decline in the physiological traits. Under 100% ETc, higher values of CO2 assimilation rate, transpiration, and instantaneous water use efficiency were recorded, and there was 50% ETc for internal carbon concentration, even with the increase in ECw.

The antifungal potential of volatile organic compounds (VOCs) produced by actinobacterial strains Streptomyces sp. (ACTB-77) and Amycolatopsis sp. (ACTB-290) from the rhizosphere of Caatinga plants against Colletotrichum musae was investigated. VOCs produced by these microorganisms (axenic and co-culture) were investigated using headspace-solid phase micro-extraction (HS-SPME) and gas chromatography-mass spectrometry (GC-MS). Although no exclusive VOC peaks were observed in the co-culture with ACTB-77, the same experiment involving ACTB-290 yielded five new peaks, including two identified alcohols, suggested as bioreductive products of the corresponding ketones by the fungus. Statistical analysis revealed that co-culture ACTB-77/C. musae has a closer similarity to the fungus than to the actinobacteria, while the co culture ACTB-290/C. musae showed closer similarity to the actinobacteria. These confirmed the more pronounced antifungal activity of the ACTB-290 strain, as observed in the fungus growth inhibition experiments. The antifungal activity of ACTB-290 was associated to its sulfur-containing metabolites, while linalool was suggested as responsible for the ACTB-77 activity.

RESUMO O efeito inseticida do óleo essencial de Piper aduncum (OEPA) e, particularmente, de seu constituinte dilapiol [1-alil-2,3-dimetoxi-4,5-(metilenodioxi) benzeno], está bem documentado na literatura e pode estar associado à sua interferência na desintoxicação enzimática em artrópodes. No entanto, não existem dados sobre a amplitude de teores de dilapiol associados à atividade inseticida, o que é necessário para estabelecer parâmetros de dose-atividade confiáveis para um produto formulado. A composição do óleo também pode sofrer alterações durante seu armazenamento após a destilação, principalmente devido a fatores ambientais como incidência de luz, oxigênio atmosférico e temperatura, que podem ser deletérios à qualidade do óleo. Neste estudo, durante quatro anos, OEPA submetido a diferentes condições de armazenamento e suas frações retificadas foram submetidos a bioensaios para avaliar seu efeito inseticida por contato tópico e contato residual contra Spodoptera frugiperda. Nossos objetivos foram determinar a relação entre o teor de dilapiol e a atividade inseticida do OEPA, e avaliar suas propriedades químicas e toxicológicas ao longo do tempo sob diferentes condições. Nossos resultados mostraram que o OEPA foi estável em relação ao teor de dilapiol e o efeito toxicológico contra S. frugiperda sob diferentes condições de armazenamento durante quatro anos. A composição química do OEPA não variou significativamente entre as condições de armazenamento. OEPA com teor de dilapiol entre 68% e 100% apresentou maior toxicidade inseticida por contato residual e tópico contra larvas de S. frugiperda.

ABSTRACT The insecticidal effect of the essential oil of Piper aduncum (EOPA), and of its constituent dillapiole [1-allyl-2,3-dimethoxy-4,5-(methylenedioxy) benzene] in particular, is well documented in the literature and can be associated with its interference with the enzymatic detoxification in arthropods. However, no data exist on the range of dillapiole content associated with insecticidal activity, which is necessary to establish reliable dose-activity parameters for a formulated product. The oil composition can also change during storage after distillation, mainly due to environmental factors such as light incidence, atmospheric oxygen and temperature, which can be deleterious to oil quality. In this study, EOPA subjected to different storage conditions over four years and its rectified fractions were submitted to bioassays to evaluate their insecticidal effect by topical contact and residual contact against Spodoptera frugiperda. Our objectives were to determine the relationship between dillapiole content and the insecticidal activity of EOPA, and to evaluate its chemical and toxicological properties over time under different conditions. Our results showed that EOPA was stable with respect to the dillapiole content and the toxicological effect against S. frugiperda under different storage conditions for four years. The overall chemical composition of the EOPA did not vary significantly among storage conditions. EOPA with dillapiole content ranging between 68% and 100% showed greater insecticidal toxicity by residual and topical contact against S. frugiperda larvae.
