Abstract The aim of the present study was to report on the occurrence of parasitism by Amblyomma rotundatum ticks on two species of Teiidae lizards and test the presence of rickettsiae in the collected ticks, in the western Brazilian Amazon region. Ticks were collected in July 2019, from a fragment of terra firme forest in the municipality of Senador Guiomard, Acre, Brazil. Two lizards that were infested by immature stages of ticks were caught using mist net and Tomahawk traps. Ectoparasites were collected manually, and the lizard specimens were identified and released at the same location where they had been caught. Three nymphs and 49 larvae were collected from Ameiva ameiva, while 25 nymphs and nine larvae were collected from Tupinambis cuzcoensis, which are both in the family Teiidae. The ticks were identified morphologically as belonging to the genus Amblyomma. Nymphs were identified at species level through molecular analysis, resulting in the tick species Amblyomma rotundatum. This is the first record of parasitism by the tick A. rotundatum on T. cuzcoensis lizard, and the first report of an association between A. rotundatum and the lizard species A. ameiva and T. cuzcoensis in Acre, in the western part of the Amazon region.

Resumo O objetivo do presente estudo foi relatar a ocorrência de parasitismo por carrapatos Amblyomma rotundatum em duas espécies de lagartos Teiidae, e testar a presença de riquétsias nos carrapatos coletados, na região da Amazônia Ocidental brasileira. Os carrapatos foram coletados em julho de 2019, em um fragmento de floresta de terra firme no município de Senador Guiomard, Acre, Brasil. Dois lagartos infestados por estágios imaturos de carrapatos foram capturados com rede de neblina e armadilhas Tomahawk. Os ectoparasitos foram coletados manualmente, e os espécimes de lagartos foram identificados e soltos no mesmo local onde foram capturados. Três ninfas e 49 larvas foram coletadas de Ameiva ameiva, enquanto 25 ninfas e nove larvas foram coletadas de Tupinambis cuzcoensis, ambas da família Teiidae. Os carrapatos foram identificados morfologicamente como pertencentes ao gênero Amblyomma. As ninfas foram identificadas em nível de espécie por meio de análise molecular, resultando na espécie de carrapato Amblyomma rotundatum. Este é o primeiro registro de parasitismo pelo carrapato A. rotundatum em lagarto T. cuzcoensis, e o primeiro relato de associação entre A. rotundatum e as espécies de lagartos A. ameiva e T. cuzcoensis, no Acre, na parte ocidental da região amazônica.

ABSTRACT Purpose: to assess the influence of dentures on the electromyographic activity of masticatory muscles in individuals with Parkinson’s disease. Methods: an analytical, quantitative, cross-sectional study conducted at a public teaching hospital in 2017, assessing the stage of the disease, non-denture (ND) wearing, upper removable partial denture wearing (DW1), upper and lower removable partial denture wearing (DW2), and upper complete denture + lower removable partial denture wearing (DW3). The Student-Newman-Keuls test was used to compare the maximum voluntary muscle contraction between sides and between the denture wearing and non-denture wearing groups. Significance was set at α<0.05. Results: after applying the eligibility criteria, 41 patient records were included in the sample. The association between the stage of the disease and denture wearing showed predominance of DW2 in stage 1 (43%). A significant difference was found in the masseter muscle analysis between the non-denture wearing group and DW2 and DW3 (p=0.0018). As for the anterior temporalis muscle, there was a significant difference (p=0.0034) in three of the analysis groups (ND vs. DW2, ND vs. DW3, and DW1 vs. DW3). Conclusion: denture wearing has a negative impact on the electrical activity of masticatory muscles when compared with individuals who do not wear dentures and have natural teeth.

ABSTRACT Purpose: to analyze factors associated with mandibular function impairment in people with Parkinson’s disease during social isolation due to COVID-19. Methods: this cross-sectional, quantitative, analytical study used a database with 115 records of patients presented with this condition (obtained via telemonitoring in a research conducted in 2020) and assessed sociodemographic aspects and the Mandibular Function Impairment Questionnaire (MFIQ). The variables addressed in the associations were sex, age, marital status, denture use, disease duration, and daily levodopa dose. Results were obtained with the Fisher´s exact test, with the significance level set at p < 0.05. Results: after analyzing the database, the final sample comprised 62 eligible records - 61% were males, 79% were above 60 years old, 63% wore dentures, and 93% had low severity of mandibular function impairment, according to MFIQ. No significant associations were found between the study variables and MFIQ (p < 0.05). Conclusion: the degree of mandibular impairment was low, and the study variables were not associated with mandibular function impairment in patients presented with Parkinson´s disease, during social isolation, due to COVID-19.

Resumo Em junho de 2013, emergiram no espaço público brasileiro diferentes grupos de direita rebelados contra o Partido dos Trabalhadores, que governava o Brasil naquele momento liderando uma grande coalizão de centro-esquerda. Desde então, uma nova direita se posiciona no debate político nacional, militando nas universidades e em outros contextos institucionais e mobilizando uma retórica agressiva contra o discurso de esquerda. O objetivo deste estudo é identificar os diferentes atributos da identidade da direita formulados em narrativas de militantes de direita de uma universidade pública brasileira, as contradições no conteúdo dessa identidade e os recursos retórico-discursivos mobilizados em sua construção. Com o uso do método de análise de discurso, foram analisadas transcrições de entrevistas realizadas com nove militantes de direita, alunos de uma universidade pública nordestina. Esses militantes mencionam três grupos políticos como constituintes da direita (os conservadores, os liberais e os libertários), mas somente dois são usados como categorias de autoidentificação: os conservadores e os libertários. Atributos identitários como o apreço pela verdade, a defesa da liberdade, a desconfiança em relação às mudanças abruptas e a valorização da família e da religiosidade cristã foram afirmados como definidores da identidade da direita. Em vários momentos, no entanto, os militantes produziam enunciados que contradiziam alguns desses atributos, revelando o caráter ambíguo e contraditório do discurso da militância estudada.

Abstract In June 2013, different right-wing groups emerged in the Brazilian public space rebelling against the Partido dos Trabalhadores, which ruled Brazil at the time leading a large center-left coalition. Since then, a new right-wing has positioned itself in the national political debate, militating in universities and other institutional contexts, and mobilizing an aggressive rhetoric against the leftist discourse. This study aims to identify the different attributes of the right-wing identity formulated in the narratives of right-wing militants in a Brazilian public university, the contradictions in the content of that identity, and the rhetorical-discursive resources mobilized in its construction. We analyzed transcripts of interviews conducted with nine right-wing activists, students from a public university in the Northeast using the speech analysis method. These militants mention three political groups as constituents of the right-wing (conservatives, liberals, and libertarians), but only two are used as categories of self-identification: conservatives and libertarians. Identity attributes such as an appreciation for the truth, the defense of freedom, a distrust of abrupt changes, and the appreciation for the family and Christian religiosity were affirmed as defining the identity of the right-wing. At various times, however, the militants produced statements that contradicted some of these attributes, revealing the ambiguous and contradictory character of the studied militancy discourse.

Resumo Introdução Dentre a população mais atingida pela Covid-19 estão os idosos, dentre estes, existem aqueles que têm a doença de Parkinson. Com o distanciamento social devido ao coronavírus, novas estratégias e ferramentas estão sendo utilizadas para o acompanhamento em saúde. Objetivo Descrever as condições de saúde bucal, por meio do telemonitoramento, de pessoas com Parkinson em tempos de Covid-19. Material e método Trata-se de um estudo analítico, quantitativo, de corte transversal. A ferramenta utilizada foi a de videochamada. Os contatos telefônicos foram obtidos das listagens de 154 pacientes do Programa de Extensão Pró-Parkinson da Universidade Federal de Pernambuco. Foi aplicado um questionário semi-estruturado com dados sociodemográficos e práticas diárias de higienização bucal de dentes e próteses, como também se o participante teve ou não necessidade de tratamento odontológico em tempos de Covid-19. Resultado A amostra final foi composta por 64 parkinsonianos. Com relação aos cuidados com a saúde bucal, a frequência de higienização neste período foi de três vezes por dia em 48,44% dos participantes, sendo a escova dental e o creme dental os itens mais utilizados para essa tarefa. Mais da metade da amostra faziam uso de prótese dentária. Os problemas de saúde bucal, mais prevalentes durante esse período de isolamento foram: dor, ferida na boca e necessidade de extração dentária. Conclusão O telemonitoramento foi essencial, pois se tratando da saúde bucal, notou-se que existe ainda um défice muito grande desses pacientes, tanto nas práticas de higienização básicas e informação sobre saúde bucal, como nos cuidados com as próteses dentárias.

Abstract Introduction The elderly are among those most affected by Covid-19, and among them are people with Parkinson's disease. Social distancing, due to the coronavirus, has led to new strategies and tools for health monitoring. Objective To describe the oral health conditions, using telemonitoring, of people with Parkinson's disease during the Covid-19 pandemic. Material and method This is an analytical, quantitative, cross-sectional study. The tool used was the video call. The telephone contacts (n=154) were obtained from lists of patients in the Pro-Parkinson Extension Program at the Federal University of Pernambuco. A semi-structured questionnaire was used to gather sociodemographic data and daily oral hygiene practices for teeth and dentures, and whether or not the participant needed dental treatment, during the Covid-19 pandemic. Result The final sample consisted of 64 Parkinsonian patients. Regarding oral health care, the frequency of hygiene in this period was three times a day among 48.44% of participants, with toothbrush and toothpaste being the items most used for this task. More than half of the sample used dental prostheses. The most common oral health problems during this isolation period were pain, mouth sores and the need for tooth extraction. Conclusion Telemonitoring was essential because it was noted that these patients were deficient in their knowledge of basic hygiene practices and in information on oral health, as well as in the care of dental prostheses.

Abstract Background: Triatomines are blood-feeding arthropods belonging to the subfamily Triatominae (Hemiptera; Reduviidae), capable of producing immunomodulatory and water-soluble molecules in their hemolymph, such as antimicrobial peptides (AMPs). In this work, we evaluated the antifungal and immunomodulatory activity of the hemolymph of Meccus pallidipennis (MPH) and Rhodnius prolixus (RPH) against Cryptococcus neoformans. Methods: We assessed the activity of the hemolymph of both insects on fungal growth by a minimum inhibitory concentration (MIC) assay. Further, RAW 264.7 macrophages were cultivated with hemolymph and challenged with C. neoformans. Then, their phagocytic and killing activities were assessed. The cytokines MCP-1, IFN-γ, TNF-α, IL-10, IL-12, and IL-6 were measured in culture supernatants 4- and 48-hours post-infection. Results: Both hemolymph samples directly affected the growth rate of the fungus in a dose-dependent manner. Either MPH or RPH was capable of inhibiting fungal growth by at least 70%, using the lowest dilution (1:20). Treatment of RAW 264.7 macrophages with hemolymph of both insects was capable of increasing the production of MCP-I and TNF-α. In addition, when these cells were stimulated with hemolymph in the presence of C. neoformans, a 2- and a 4-fold increase in phagocytic rate was observed with MPH and RPH, respectively, when compared to untreated cells. For the macrophage killing activity, MPH decreased in approximately 30% the number of viable yeasts inside the cells compared to untreated control; however, treatment with RPH could not reduce the total number of viable yeasts. MPH was also capable of increasing MHC-II expression on macrophages. Regarding the cytokine production, MCP-I and TNF-α, were increased in the supernatant of macrophages treated with both hemolymphs, 4 and 48 hours after stimulation. Conclusion: These results suggested that hemolymph of triatomines may represent a source of molecules capable of presenting antifungal and immunomodulatory activity in macrophages during fungal infection.

Resumo Em 2013, no Brasil, emergem na cena política diversos agrupamentos políticos identificados com a direita política e unidos contra a esquerda e a permanência do Partido dos Trabalhadores no governo brasileiro. Este estudo investiga esse fenômeno no contexto da região Nordeste do Brasil. Seu objetivo é compreender como a militância de direita, em uma cidade média nordestina, organiza discursivamente uma identidade para si e para os grupos que elegem como antagonistas. Com o uso do método de análise de discurso, o estudo investiga transcrições de entrevistas realizadas com nove membros dessa militância. As categorias conservador, libertário e liberal foram usadas como posições de autoidentificação por esses militantes. O modo como descrevem essas categorias revela a pluralidade da direita, evidenciando as complexas relações e as contradições presentes no seu interior.

Abstract In 2013, Brazil saw the emergence of several political groups identified with right-wing politics and united against the left and the Worker’s Party consecutive administration. This paper investigates the characteristics of this phenomenon in northeastern Brazil to understand how right-wing militancy discursively organizes its identity and that of groups it chooses as antagonists. Based on discourse analysis, the study analyzes transcripts of interviews conducted with nine members of this militancy. Categories such as conservative, liberal and libertarian were used by the interviewees as self-identifying positions. How they describe these categories reveals the plurality of the political right, highlighting its complexity and contradictions.

Resumo Introdução As alterações causadas pela rigidez na Doença de Parkinson (DP) podem afetar a musculatura mandibular, mas há uma escassez de estudos publicados sobre seu impacto na abertura bucal. Objetivo Analisar a relação da extensão vertical da abertura de boca com a rigidez muscular e os fatores sociodemográficos de idosos com a DP. Material e método Trata-se de um estudo transversal, quantitativo, que coletou dados de uma pesquisa primária realizada no Hospital das Clínicas da Universidade Federal de Pernambuco, em 2018. Apanhou-se dados dos prontuários e do questionário: Critério de Diagnóstico de Pesquisa para Disfunções Temporomandibulares (RDC/TMD). A amostra foi composta por 81 parkinsonianos e caracterizadas em: variáveis sociodemográficas e presença ou ausência de rigidez muscular. As medidas de extensão vertical de abertura de boca avaliadas foram: abertura de boca sem auxílio e sem dor (ABASD) e abertura máxima da boca sem auxílio (AMBSA). Aplicou-se os testes de correlação linear de Pearson e de correlação de Spearman para averiguar relação entre as variáveis contínuas. Análises de associações foram realizadas através da regressão logística simples. Nível de significância de p<0,05. Resultado A limitação de abertura de boca não apresentou relação com a idade e o sexo. O maior nível de significância foi entre a abertura de boca sem auxílio e sem dor e a rigidez muscular (p= 0,012) e a escolaridade (p= 0,038). Conclusão A limitação de abertura de boca nas pessoas com DP se mostrou relacionada a rigidez muscular e a escolaridade mais baixa.

Abstract Introduction Changes caused by the rigidity of Parkinson’s Disease (PD) can affect the mandibular musculature. However, few studies have been published about its impact on the oral opening. Objective To analyze the relationship of the vertical extension of the oral opening with muscular rigidity and sociodemographic factors of the elderly with PD. Material and method This is a cross-sectional, quantitative study that collected data from a primary study conducted at the Hospital das Clínicas of the Federal University of Pernambuco in 2018. Data were collected from medical records and from the questionnaire, Research Diagnostic Criterion for Temporomandibular Disorders (RDC/TMD). The sample was composed of 81 parkinsonians and characterized using: sociodemographic variables and the presence or absence of muscular rigidity. The measures of vertical extension of the oral opening evaluated were: mouth opening without assistance and without pain (ABASD), and maximum mouth opening without assistance (AMBSA). The Pearson’s linear correlation and Spearman’s correlation tests were applied to investigate the relationship among the continuous variables. Analyses of association were conducted using simple logistic regression. The level of significance was set at p<0.05. Result Limitation of the oral opening was not related to age or sex. The greatest level of significance was between mouth opening without assistance and without pain and muscular rigidity (p=0.012), and years of schooling (p=0.038). Conclusion The limitation of mouth opening in people with PD was shown to be related to muscular rigidity and fewer years of schooling.

ABSTRACT Objective: To describe the sociodemographic profile of elderly people with temporomandibular disorder and depression in Parkinson's disease cases. Material and Methods: It is a cross-sectional cohort cut study, which used secondary data from 124 elderly people with Parkinson’s disease (PD). To diagnose temporomandibular disorder (TMD), the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) questionnaire was used, and the variables studied were: age, sex, race, education, marital status, family income, stage of the disease, and depression. The statistical analysis performed was descriptive and used absolute numbers and a frequency count. Results: After the application of the eligibility criteria, the patient records of 81 elderly people with Parkinson’s disease were selected; 15 presented associated TMD and depression. The average age was 69 years old; 66.67% were male; 46.67% had more than 9 years of schooling; 60% were married or had a partner; 53.33% received between 1 and 2 minimum wages; 33.33% stated they were brown; 80% were in the moderate stage of the disease; 46.66% were in group II according to the RDC/TMD, presenting disk displacement; and 53.33% presented severe depression. Conclusion: It was verified that the elderly people with Parkinson’s and associated TMD and depression were male, married or with a partner, on a low income, with nine or more years of schooling, and were in the moderate stage of the disease.

ABSTRACT Purpose: to analyze the predictors of temporomandibular disorder in people with Parkinson’s disease, verifying their associations with sociodemographic aspects and stages of the disease. Methods: a study based on secondary data from research conducted in 2017 with 110 people with Parkinson’s disease. They were assessed with the Research Diagnostic Criteria for Temporomandibular Disorders and the Parkinson’s disease staging scale. The studied predictive variables for temporomandibular disorder were pain, crepitation, clicking, nighttime and daytime clenching/gnashing, uncomfortable/non-habitual bite, morning rigidity, and tinnitus. The sociodemographic aspects assessed were age, sex, schooling level, marital status, income, and stages 1 to 3 of the disease. The chi-squared odds ratio was used with a 95% confidence interval and significance level at p < 0.05. Results: an association was verified between nighttime clenching/gnashing and income (p = 0.006); tinnitus and income range from ½ to 3 (p = 0.003) and from 4 to 10 minimum wages (p = 0.004); and between tinnitus and stage 1 (p = 0.02). Conclusion: this study verified that the predictors associated with temporomandibular disorder in people with Parkinson’s disease were pain, clicking, crepitation, uncomfortable/non-habitual bite, and morning rigidity. It was verified that income and stage 1 of the disease had an association with nighttime clenching/gnashing and tinnitus.

RESUMO Objetivo Avaliar se a dieta com restrição de carboidratos acarreta níveis elevados de desejos intenso por comida em indivíduos com compulsão alimentar. Métodos Participaram 146 indivíduos com compulsão alimentar divididos nos Grupos Dieta Low Carb (n=48) e Grupo Controle (n=98). Foram utilizados como medidas: Escala de Compulsão Alimentar Periódica, Questionário de Hay, Questionário de Desejos Intensos por Comida – Traço e Estado, Subescala de restrição cognitiva e sua versão adaptada para a restrição cognitiva direcionada aos carboidratos. Foram utilizados testes paramétricos para comparação entre grupos (teste t de Student) e o teste de correlação de Pearson para verificar correlações entre variáveis de interesse. Resultados Não foram encontradas diferenças entre grupos com e sem prática de dieta em relação ao nível de compulsão alimentar ou ao escore total para desejos intensos por comida. As diferenças encontradas foram os maiores níveis de restrição cognitiva (p=0,01), restrição cognitiva para carboidratos (p=0,01) e subescalas de ‘culpa por causa dos desejos’ (p=0,04) no Grupo Dieta Low Carb. Conclusão Indivíduos com compulsão alimentar e histórico de dieta com restrição de carboidratos (low carb) possuem maior restrição cognitiva direcionada aos carboidratos e associação com atitudes alimentares alteradas (culpa pelos desejos).

ABSTRACT Objective To evaluate whether the carbohydrate-restricted diet leads to higher levels of food cravings in individuals with binge eating. Methods A total of 146 individuals with binge eating participated in the Low-Carb Diet Group (n=48) and Control Group (n=98). The Binge Eating Scale, Hay’s questionnaire, Food Cravings Questionnaire - Trait and State, Cognitive restraint subscale and its adapted version for the cognitive restraint toward carbohydrates, were used as measures. Parametric tests were used for comparison between groups (Student’s t test), and Pearson’s correlation test to verify correlations between variables of interest. Results No differences were found between groups with and without diet concerning the level of binge eating or food craving total score. The differences found were the higher levels of cognitive restraint (p=0.01), cognitive restraint for carbohydrates (p=0.01) and subscales of ‘guilt about food craving’ (p=0.04) in the Low-Carb Diet Group. Conclusion Individuals with binge eating and a history of low-carb diet have greater cognitive restraint toward carbohydrates and association with altered eating attitudes (guilt about food craving).

ABSTRACT The aim of this research was to evaluate the physiological and productive aspects of irrigated cassava crop. The statistical design used was randomised blocks, with six treatments and four replications. The used treatments were irrigation levels, based on the crop evapotranspiration – ETC – (L0 = 0% [rainfed], L1 = 40%, L2 = 80%, L3 = 120%, L4 = 160% and L5 = 200% of the ETC) and the analysed physiological variables were: gas exchange, the quantum efficiency of photosystem II (PSII) and the soil plant analysis development (SPAD) index. The growth and crop productivity were also evaluated through of the leaf area index (LAI), the number and productivity of commercial roots and total biomass. In this research, the total irrigation depth was defined as the irrigation depth plus the effective rainfall. The estimated ETC was 1,030 mm over the 12-month production cycle and the greatest value for LAI and SPAD were 7.6 and 57.4, respectively, obtained in irrigated areas with the level of 80% of the ETC. While, in the areas irrigated with 120% of the ETC, were obtained the highest values of root productivity (93 Mg·ha–1), total biomass yield (149 Mg·ha–1) and photosynthetic rate (22.4 μmol CO2·m–2·s–1). On the other hand, with irrigation equivalent at 200% of the ETC were obtained the greatest values of internal CO2 concentration (245 μmol CO2·m–2·s–1), stomatal conductance (0.35 μmol H2O·m–2·s–1) and effective quantum efficiency (0.68).

RESUMO A busca por alternativas para aumentar a produtividade e a sustentabilidade da pecuária na região Amazônica sem aumentar o desmatamento é desafiadora. Pastagens consorciadas de gramíneas com amendoim forrageiro (Arachis pintoi) têm mostrado impactos econômicos positivos. Porém, lacunas no conhecimento da biologia reprodutiva do amendoim forrageiro tem limitado o desenvolvimento de novas cultivares adaptadas as variações ambientais na Amazônia brasileira. Pastos consorciados de Brachiaria humidicola com amendoim forrageiro (cv. Mandobi) apresentaram cerca de 42% de aumento na produtividade do ganho de peso. Novas cultivares mais adaptadas ao clima amazônico, poderão trazer ganhos ainda maiores. O objetivo desse estudo foi avaliar o sistema reprodutivo em vinte acessos de A. pintoi e aproximadamente 40 progênies por acesso, genotipadas com oito microssatélites (ou marcadores). Os parâmetros de diversidade genética e endogamia, taxa de cruzamento e coancestria foram calculados. A heterozigosidade observada foi significativamente maior e o índice de fixação foi significativamente menor nos adultos comparado às progênies. A taxa de cruzamento foi variável entre os genótipos (2 a 80%) e a média da taxa de cruzamento foi 36%. Esses resultados indicam que a presença de polinizadores em pastagens pode influenciar o fluxo gênico em A. pintoi mais do que o esperado. Arachis pintoi apresentou um sistema de cruzamento misto com predominância de autofecundação e as famílias apresentaram endogamia e diferentes níveis de parentesco. Novas estratégias de conservação de genótipos são necessárias para evitar polinizadores mediadores de cruzamento entre os acessos.

ABSTRACT The search for alternatives to increase productivity and sustainability of livestock production in the Amazon region without increasing deforestation is challenging. Mixed pastures of grasses with forage peanut (Arachis pintoi) have shown positive economic impacts. However, gaps in the knowledge of the reproductive biology of A. pintoi have limited the development of new cultivars adapted to the environmental variations in the Brazilian Amazon. Pasture consortiums of Brachiaria humidicola with forage peanuts (cv. Mandobi) resulted in a 42% increase in weight gain productivity. New cultivars better adapted to the Amazon climate should bring even greater gains. We evaluated the mating system in twenty A. pintoi accessions, and approximately 40 offspring per accession genotyped with eight microsatellites (or markers). The parameters of genetic diversity and inbreeding, the outcrossing rate and coancestry were calculated. The observed heterozygosity was significantly higher and the fixation index was significantly lower in adults compared with the offspring. The crossing rate was variable among genotypes (2 to 80%), and the mean outcrossing rate was 36%. These results indicate that pollinator presence in pastures can influence gene flow in A. pintoi more than expected. Arachis pintoi presented a mixed mating system with a predominance of selfing, and families presented inbreeding and different levels of relatedness. New strategies of genotype conservation are needed to avoid pollinator-mediated crossing between accessions.

ABSTRACT Lippia alba (Mill.) N.E.Br. ex Britton & P. Wilson, Verbenaceae, is considered a great source of a bioactive volatile oil. Due to the wide range of known chemotypes, its chemical analysis is very important. Among the several activities of this volatile oil, a potential larvicidal action against Culicidae species is highlighted. However, the low water miscibility of volatile oils limits their application in aqueous media. Oil in water nano-emulsions are in the spotlight of novelty to solve this main problem. Thus, the aim of the present study was to obtain this nanostructured system with L. alba volatile oil (citral chemotype) and evaluate its larvicidal activity against Aedes aegypti and Culex quinquefasciatus larvae. The major compounds were geranial (30.02%) and neral (25.26%). Low mean droplet size (117.0 ± 1.0 nm) and low polydispersity index (0.231 ± 0.004) were observed and no major changes were observed after seven days of storage. LC50 values against C. quinquefasciatus and A. aegypti third-instar larvae were respectively 38.22 and 31.02 ppm, while LC90 values were, respectively, 59.42 and 47.19 ppm. The present study makes use of a low energy, solvent-free and ecofriendly method with reduced costs. Thus, this paper contributes significantly to phyto-nanobiotechnology of larvicidal agents, opening perspectives for the utilization of L. alba volatile oil in integrated practices of vector control.
