| phylogeny and molecular taxonomy of the rhodniini derived from mitochondrial and nuclear dna sequences. | eleven species of rhodnius and one of psammolestes were compared by dna sequence analysis of fragments of the mitochondrial large subunit ribosomal rna (mtlsurrna), the mitochondrial cytochrome b (mtcytb), and the d2 variable region of the 28s nuclear rna (d2), totaling 1,429 base pairs. the inferred phylogeny, using triatoma infestans as an outgroup, revealed two main clades within the rhodniini--one, including the prolixus group of species (rhodnius prolixus, rhodnius robustus, rhodnius neglec ... | 2000 | 11220761 |
| genetic studies of psammolestes tertius (hemiptera: reduviidae: triatominae) using male genital morphology, morphometry, isoenzymes, and random amplified polymorphic dna. | two brazilian populations of psammolestes tertius (ceará and minas gerais) collected from thornbird nests (furnariidae) were compared by male genital morphology, morphometry, isoenzymes, and random amplified polymorphic dna (rapd). male genitalia showed no difference between the populations. in contrast, morphometry, isoenzyme, and rapd clearly distinguished the two populations. possible mechanisms of dispersal and the origin of psammolestes are discussed. | 2001 | 11444017 |
| allozyme relationships among ten species of rhodniini, showing paraphyly of rhodnius including psammolestes. | genetic relationships among 10 species of bugs belonging to the tribe rhodniini (hemiptera: reduviidae), including some important vectors of chagas disease, were inferred from allozyme analysis of 12 enzyme loci (out of 21 enzyme systems examined), using agarose gel electrophoresis. these species formed two clusters: one comprising rhodnius brethesi, r. ecuadoriensis, r. pallescens and r. pictipes; the other with psammolestes tertius, rhodnius domesticus and the rhodnius prolixus group comprisin ... | 2002 | 11963985 |
| wild habitat and related fauna of panstrongylus lutzi (reduviidae, triatominae). | although panstrongylus lutzi (neiva and pinto) is currently the fifth most frequent species of triatominae captured in artificial structures in brazil, its silvatic habitat remains unknown. a survey of its natural ecotopes was performed in an area of bahia state. p. lutzi nymphal instars and adults were detected in burrows of dasypodidae. silvatic habitat of four other endemic triatomine species of the caatinga (triatoma pseudomaculata correa and espinola, triatoma brasiliensis neiva, rhodnius n ... | 2003 | 14765681 |
| [spatial distribution of triatominae populations (hemiptera: reduviidae) in mauritia flexuosa palm trees in federal district of brazil]. | to determine and analyze the distribution of triatominae sylvatic populations in the federal district of brazil, 150 mauritia flexuosa palm trees were sampled in six veredas of different landscapes (sylvatic, rural and peri-urban) in the rainy season. triatomines were morphologically identified and grouped by sex and nymphal stage and were examined to verify infection by trypanosoma cruzi and trypanosoma rangeli. twenty eight (18.6%) palm trees were infested by rhodnius neglectus and fourteen (9 ... | 2004 | 15330065 |
| Infestation of Mauritia flexuosa palms by triatomines (Hemiptera: Reduviidae), vectors of Trypanosoma cruzi and Trypanosoma rangeli in the Brazilian savanna. | To determine the infestation and trypanosome infection of triatomines captured in Mauritia flexuosa palm trees across its geographic distribution in the Brazilian savanna (Cerrado), we sampled 42 localities in eight states and in the Federal District, Brazil, between July 2005 and January 2010. Overall, 2154 specimens of the species Rhodnius neglectus, Psammolestes tertius, Triatoma sordida, and Microtriatoma borbai, were collected. Among the 341 palms sampled, 182 (53.3%) were infested with R. ... | 2012 | 22037200 |
| new record and cytogenetic analysis of psammolestes tertius lent & jurberg, 1965 (hemiptera, reduviidae, triatominae) from bahia state, brazil. | this paper reports on the first occurrence of psammolestes tertius in the chapada diamantina region, located in the city of seabra, bahia state, in northeastern brazil. following an active search, 24 p. tertius specimens were collected from phacellodomus rufifrons (rufous-fronted thornbird) nests. the insects did not present any symptoms of infection by trypanosoma cruzi. p. tertius males were cytogenetically analyzed, and the results were compared with those of other specimens from the brazilia ... | 2016 | 27420943 |
| [triatominae species] | this paper provides a checklist of 15 known species of the triatominae subfamily in maranhão state. on the coastal são luís island there are a total of 10 species associated with sylvatic areas (eratyrus mucronatus, psammolestes tertius, panstrongylus diasi) and periurban and urban areas (panstrongylus geniculatus, panstrongylus lignarius, rhodnius nasutus, rhodnius neglectus, rhodnius pictipes, rhodnius robustus and triatoma rubrofasciata). the last was found only on são luís island, while the ... | 1998 | 9592224 |
| spermiotaxonomy of the tribe rhodniini (hemiptera, triatominae). | the tribe rhodniini is a monophyletic group composed of 22 species, with 19 in the rhodnius genus and three in the psammolestes genus. these insects are morphologically very similar (cryptic species), and new tools are important for investigating the taxonomy of these vectors. spermiotaxonomy is an important tool in differentiating between related species, and this study analyzed the spermatids of rhodniini species to elucidate their spermiotaxonomy. all of the rhodniini species contained two he ... | 2016 | 27050980 |
