1. Qual o repelente mais indicado para crianças de 6 meses a 2 anos?
Os repelentes indicados para crianças de 6 meses até 2 anos de idade são aqueles à base de IR3535.
Embora o FDA (Food and Drug Administration – EUA) indique evitarem-se repelentes apenas antes dos 2 meses, as recomendações oficiais da ANVISA (Agência Nacional de Vigilância Sanitária – Brasil) restringem o uso para crianças acima de 6 m

2. Distribution of gall-inducing arthropods in areas of deciduous seasonal forest of Parque da Sapucaia (Montes Claros, MG, Brazil): effects of anthropization, vegetation structure and seasonality
Abstract In the present study, we inventoried gall-inducing arthropod species and evaluated the effects of habitat anthropization, vegetation structure and seasonality on this group in areas of deciduous seasonal forest of Parque da Sapucaia, Montes Claros, MG, Brazil. The gall-inducing fauna was sampled between April 2017 and February 2018 from 20 plots dis

3. Infracommunities of bat flies (Diptera: Streblidae and Nycteribiidae) of bats (Mammalia: Chiroptera) in three conservation units in the State of Amapá, Brazil
Resumo: Dípteros pertencentes as famílias Nycteribiidae e Streblidae são ectoparasitos hematófagos, sendo exclusivamente de morcegos. O estado do Amapá localiza-se na região Norte do Brasil e representa um dos estados com as menores taxas de desmatamento do país, com aproximadamente 80% do território preservado. Dentro do Estado, existem as unidades

4. The insect reservoir of biodiversity for viruses and for antiviral mechanisms
Abstract: Insects are the most diverse group of animals. They can be infected by an extraordinary diversity of viruses. Among them, arthropod-borne viruses (arboviruses) can be transmitted to humans. High-throughput sequencing of small RNAs from insects provides insight into their virome, which may help understand the dynamics of vector borne infectious dise

5. Impacto da remoção de serapilheira sobre a comunidade de artrópodes edáficos em plantios abandonados de Corymbia citriodora
Resumo Experimentos de manipulação podem contribuir para a compreensão do papel ecológico da serapilheira em ecossistemas florestais. No entanto, há poucos estudos desta natureza. Os efeitos da remoção da camada de serapilheira (RS) foram avaliados sobre a comunidade de artrópodes do solo em dois plantios abandonados de Corymbia citriodora, em difere

6. Association between MBL2 haplotypes and dengue severity in children from Rio de Janeiro, Brazil
BACKGROUND Dengue is an arthropod-borne viral disease with a majority of asymptomatic individuals and clinical manifestations varying from mild fever to severe and potentially lethal forms. An increasing number of genetic studies have outlined the association between host genetic variations and dengue severity. Genes associated to viral recognition and ent

7. Exploring the Insecticide and Acaricide Potential of Development Regulators obtained from Restinga vegetation from Brazil
Abstract: As a part of our continuing search for insect and arthropod development regulators from Brazilian restinga vegetation of the Rio de Janeiro State, crude extracts, purified fractions and essential oils were submitted to screening tests seeking for biological activities on the development of the insects Rhodnius prolixus, Dysdercus peruvianus, Oncope

8. West Nile virus infections are here! Are we prepared to face another flavivirus epidemic?
Abstract Emerging arthropod-borne viruses (arboviruses), such as chikungunya and Zika viruses, are a major threat to public health in countries like Brazil where biodiversity is high and medical care is sometimes precarious. West Nile fever is a disease caused by the West Nile Virus (WNV), an RNA virus belonging to the Flaviviridae family. It is transmitted

9. Species Diversity and Community Structure of Arthropod Pests and Predators in Flax, Linum Usitatissimum L. from Darjeeling (India)
ABSTRACT The species richness and relative abundances of different aboveground plant-dwelling pest and predator species were assessed in flax (Linum usitatissimum L.) ecosystem under mid-hill conditions of eastern Himalayas. The experiment was conducted in winter seasons during 2004-2013 at the Regional Research Station (Hill Zone), Uttar Banga Krishi Viswav

10. Field evaluation of sticky BR-OVT traps to collect culicids eggs and adult mosquitoes inside houses
Abstract INTRODUCTION: Culex quinquefasciatus is a mosquito of importance to public health, as it represents a real and/or potential risk for the transmission of pathogens to humans, such as some arthropod-borne viruses and nematodes that cause filariasis. In Brazil, three municipalities in the Metropolitan Region of Recife (RMR) that are endemic for lympha

11. Follow up of a robust meta-signature to identify Zika virus infection in Aedes aegypti: another brick in the wall
The mosquito Aedes aegypti is the main vector of several arthropod-borne diseases that have global impacts. In a previous meta-analysis, our group identified a vector gene set containing 110 genes strongly associated with infections of dengue, West Nile and yellow fever viruses. Of these 110 genes, four genes allowed a highly accurate classification of infec

12. Evaluating the use of fluorescence-based flow cytometry assay for dengue diagnosis using peripheral blood mononuclear cells
Abstract INTRODUCTION: Dengue virus (DENV) is the most important arthropod-borne viral disease worldwide with an estimated 50 million infections occurring each year. METHODS: In this study, we present a flow cytometry assay (FACS) for diagnosing DENV, and compare its results with those of the non-structural protein 1 (NS1) immunochromatographic assay and
