“…T. rubrofasciata seems strongly associated with domestic and peridomestic habitats -especially with rats (especially Rattus rattus) -and is frequently infected with the rat trypanosome T. conorhini. It is also competent as a vector of T. cruzi, and considered to be the most significant vector of Chagas disease on the Island of São Luis de Maranhão, Brazil (Rebêlo et al, 1998).…”

“…Coura et al (1994) also conducted field studies in the municipality of Barcelos and verified the attacking behavior of R. brethesi. It has been shown that its geographical distribution includes damp areas in the states of Amazonas and Pará, in the Northern region of Brazil, and in drier areas of the state of Maranhão, in the Northeastern region of the country (Rebelo et al 1998). There have also been reports of the presence of this species in Colombia and Venezuela (Carcavallo et al 1999.…”

The occurrence of autochthonous cases of Chagas disease in the Amazon region of Brazil over recent decades has motivated an intensification of studies in this area. Different species of triatomines have been identified, and ten of these have be proven to be carriers of the parasite Trypanosoma cruzi or "cruzi-like" parasites. Studies conducted in the municipalities of Santa Isabel do Rio Negro and Barcelos, located on the Upper and Middle of the Negro River, microregion of Negro River, state of Amazonas have confirmed not only thatRhodnius brethesi is present in the palm tree Leopoldinia piassaba, but also that this insect was recognized by palm fiber collectors. A morphological study of eyes, inter-ocular and inter-ocellar regions, antennae, buccula, labrum, rostrum, stridulatory sulcus and feet, including the apex of the tibia, spongy fossette and ctenidium was conducted by scanning electron microscopy. The buccula and the stridulatory sulcus presented notable differences in specimens of different genera and also of different species. These data make it possible to suggest that the details presented in these structures can be included as diagnostic characteristics to be used in new dichotomous keys, thereby contributing towards studies of taxonomy and systematics and furnishing backing for comparative analysis of specimens collected from different localities.Key words: Rhodnius brethesi -external morphology -taxonomy -scanning electron microscopy -Amazon region -Brazil Over recent years, attention has been drawn to Chagas disease infection in the Amazon region of Brazil because of increased numbers of reports of acute cases and the presence of individuals who are serologically positive for this infection (Coura et al. 1995, 2002a, Fraiha Neto et al. 1995, Valente et al. 1999, Dias et al. 2002. So far, it is unclear whether these growing numbers of human cases are due to increased transmission or whether they are the result from an active search for positive cases. This latter is the case in the state of Pará, where greater numbers of small outbreaks attributed to contamination by oral transmission have been described (Valente et al. 1999).One of the epidemiological profiles discerned in the Amazon region that has received deserved attention is the one found in the Upper and Middle Negro River region, microregion of Negro River in the state of Amazonas. Initial investigations by Coura et al. (1994Coura et al. ( , 1995 indicated that the presence of human infection in areas of the Negro River were associated with extractive activities relating to the collection of fiber from the native palm tree Leopoldinia piassaba Wallace, 1853. The link in the transmission cycle was pinpointed as the contact between the fiber gatherer and the species of triatomines present in the extraction areas (Coura et al. 2002a). The data obtained though that investigation showed that two vector species were present in the extraction areas: Rhodnius brethesi Matta, 1919, and Panstrongylus geniculatus (Latreille, 1811). The first of th...

“…On the other hand, Rebêlo et al (1998) and Galvão et al (2003) recorded fifteen and sixteen species of Triatominae in the state of Maranhão, Brazil, respectively, without mentioning any Cavernicola spp. It is noteworthy that although these two studies recorded almost the same species in Maranhão, Triatoma maculata (Erichson, 1848) was mentioned only by Rebêlo et al (1998), while Rhodnius domesticus Neiva &Pinto, 1923 andTriatoma sordida (Stål, 1859) were recorded only by Galvão et al (2003), thus making a total of 17 species already recorded in this state (Table 1).…”

“…The material was deposited in the Entomological Collection of "Museu Nacional da Universidade Federal do Rio de Janeiro" (MNRJ), Rio de Janeiro, Brazil. The specimens were identified following Lent and Jurberg (1969), Lent and Wygodzinsky (1979) and Oliveira et al (2007), and Rebêlo et al (1998) and Galvão et al (2003). were fully in accordance with these previous descriptions.…”
