1. Occurrence of triatomines in an urban residential complex in the municipality of Rio Branco, Acre, South-Western Amazon
Abstract INTRODUCTION: This study describes the occurrence of triatomines, and their positivity for trypanosomatids, in a residential complex in Rio Branco, Acre, Brazil. METHODS: Triatomines were collected through direct capture in a home environment. Positivity analysis for trypanosomatids was performed by PCR assays. RESULTS Collected insects consis

2. Sympatry influence in the interaction of Trypanosoma cruzi with triatomine
Abstract INTRODUCTION: Trypanosoma cruzi, the etiologic agent of Chagas disease, is widely distributed in nature, circulating between triatomine bugs and sylvatic mammals, and has large genetic diversity. Both the vector species and the genetic lineages of T. cruzi present a varied geographical distribution. This study aimed to verify the influence of sympa

3. Triatominae species of Suriname (Heteroptera: Reduviidae) and their role as vectors of Chagas disease
Nine species of Triatominae, representing three tribes and five genera, are currently known in Suriname. An annotated list of the species based on the collections of the Bureau of Public Health (Suriname), the National Zoological Collection Suriname and the National History Museum Leiden (the Netherlands) is provided. Additionally, the results of several yea

4. New focus of active transmission of Chagas disease in indigenous populations in the Peruvian Amazon basin
Introduction Several cases of acute Chagas disease (ACD) have been reported in the Peruvian Amazon basin. Methods The objective was to describe and investigate 6 ACD cases in children from indigenous Amazon communities in the province of Datem del Marañón in Loreto department (2006-2010). Results The mean age was 3.6 years. All patients had fever, 4/6

5. Rhodnius barretti, a new species of Triatominae (Hemiptera: Reduviidae) from western Amazonia
Rhodnius barretti , a new triatomine species, is described based on adult specimens collected in rainforest environments within the Napo ecoregion of western Amazonia (Colombia and Ecuador). R. barretti resembles Rhodnius robustus s.l. , but mitochondrial cytochrome b gene sequences reveal that it is a strongly divergent member of the “robustus lineage”

6. Infecção natural de triatomíneos (Hemiptera: Reduviidae) por tripanosomatídeos em dois ambientes distintos no município de Ouro Preto do Oeste, Estado de Rondônia, Brasil
INTRODUÇÃO: O estudo analisou a ocorrência e o índice de contaminação por tripanosomatídeos de triatomíneos em Orbynia speciosa no Estado de Rondônia, Brasil, em 2 ambientes (pastagem e floresta). MÉTODOS: Captura em palmeiras e esfregaços do conteúdo do tubo digestivo dos triatomíneos analisados por microscopia óptica. RESULTADOS: Capturaram-s

7. Biologia comparativa e comportamento alimentar de Rhodnius neglectus e Rhodnius robustus (Triatominae) sob condições de laboratório
INTRODUÇÃO: A competência vetorial de triatomíneos é determinada a partir de estudos sobre biologia e comportamento alimentar em condições de campo e/ou laboratório. Fatores como número de picadas, quantidade de sangue ingerido e tempo de defecação têm implicações na transmissão de tripanosomatídeos. Parâmetros biológicos e comportamentais

8. Attraction of Chagas disease vectors (Triatominae) to artificial light sources in the canopy of primary Amazon rainforest
Adult triatomines occasionally fly into artificially lit premises in Amazonia. This can result in Trypanosoma cruzi transmission to humans either by direct contact or via foodstuff contamination, but the frequency of such behaviour has not been quantified. To address this issue, a light-trap was set 45 m above ground in primary rainforest near Manaus, state

9. Ocorrência de triatomíneos em ambientes silvestres e domiciliares do município de Manaus, Estado do Amazonas
A análise da distribuição de triatomíneos é essencial para a formulação de estratégias de controle da doença de Chagas na Região Amazônica. Neste trabalho, apresentam-se os resultados de capturas realizadas em ambientes silvestres e artificiais, em localidades rurais e urbanas de Manaus, Amazonas. Dos 115 triatomíneos coletados, 85 (73,9%) são d

10. The triatominae species of French Guiana (Heteroptera: Reduviidae)
An annotated list of the triatomine species present in French Guiana is given. It is based on field collections carried out between 1993-2008, museum collections and a literature review. Fourteen species, representing four tribes and six genera, are now known in this country and are illustrated (habitus). Three species are recorded from French Guiana for the

11. Reassessing the entomological investigation around the first autochthonous case of Chagas disease in Western Brazilian Amazon
In 1979, the first autochthonous case of Chagas disease in the Western Brazilian Amazon was reported and an entomological survey was carried out around it. Specimens of Rhodnius pictipes and Rhodnius robustus were collected in intradomicile and sylvatic ecotopes. Adult bugs were infected with trypanosomatids. Invasion of houses by triatomines was demonstrate

12. Análise proteômica das salivas dos triatomíneos Rhodnuis brethesi, Rhodnius robustus e Panstrongylus megistus, vetores da doença de Chagas
Triatomine bugs acting as vectors of Chagas‟ disease are haematophagous organisms in all of its evolvement phases. Their feeding success is greatly related to their salivary glands content. The presence of a pool of specific proteins allows this insect to access its food by counteracting host haemostatic mechanisms, such as platelet aggregation, clotti
