Study of the salivary glands in Triatominae (Hemiptera, Reduviidae, Triatominae): Their Color and Application to the Chagas Disease Vector Evolution
(2017-01-01)
Chagas disease is caused by Trypanosoma cruzi and transmitted by feces of a triatomine that has the habit of defecating during blood feeding. The salivary glands of triatomines are important to hematophagy because their ...
Evidenciação de antígeno da hepatite B (HBsAg) em manchas obtidas de exemplares de Triatominae: nota prévia
(Faculdade de Saúde Pública da Universidade de São Paulo, 1976-09-01)
A total of 890 impressions on filter paper identified as containing human blood, were examined for the presence of hepatitis B antigen (HBsAg), using the Hepanosticon haemagglutination and radioimmunoassay techniques. The ...
Karyotype Evolution of Chagas Disease Vectors (Hemiptera, Triatominae)
(Amer Soc Trop Med & Hygiene, 2018-01-01)
The Triatominae subfamily is composed of 153 hematophagous species that are potential vectors of Trypanosoma cruzi, the etiological agent of Chagas disease. Karyotypic studies in triatomines were initiated in 1909. There ...
Description of the female and new records of Triatoma baratai Carcavallo & Jurberg, 2000 (Hemiptera: Heteroptera: Reduviidae: Triatominae) from Mato Grosso do Sul, Brazil, with a key to the species of the Triatoma matogrossensis subcomplex
(Magnolia Press, 2012-01-05)
Triatoma baratai Carcavallo & Jurberg, 2000, a species similar to Triatoma williami Galvao, Souza & Lima, 1967 and belonging to the T. matogrossensis subcomplex, was described based on a male specimen collected in a sylvatic ...
Characterization of the external female genitalia of six species of Triatominae (Hemiptera: Reduviidade) by scanning electron microscopy
(Fundacão Oswaldo Cruz, 2010-05-01)
By macroscopic and microscopic dorsal side observation, it was noted that the IX and X segments of two species each of Panstrongylus and Triatoma terminate in an elongated way, whereas they terminate abruptly in the two ...
Description of eggs and nymphal instars of Triatoma baratai Carcavallo and Jurberg, 2000 based on optical and scanning electron microscopy (Hemiptera: Reduviidae: Triatominae)
(2009-04-06)
Triatoma baratai Carcavallo & Jurberg, is a wild (i.e., nonperidomestic) species found in the State of Mato Grosso do Sul (Bodoquena region, county of Bonito), Brazil. Its eggs and nymphs are described here based on optical ...
Ribosomal DNA ITS-1 intergenic spacer polymorphism in triatomines (Triatominae, Heteroptera)
(Springer, 2005-08-01)
The length polymorphism of ribosomal DNA ITS-1 intergenic spacer was analyzed in eight species of triatomines belonging to Triatoma, Rhodnius, and Panstrongylus genera. The analyzed species were Rhodnius domesticus, R. ...
Molecular cytotaxonomy of the Triatoma brasiliensis species subcomplex (Hemiptera, Triatominae)
(2020-01-01)
The Triatoma genus is paraphyletic, and its species are grouped into complexes and subcomplexes. Given the fact that species that make up a given subcomplex generally share chromosomal traits, we analyzed the distribution ...
Phylogenetic and phenotypic relationships of the Triatoma sordida subcomplex (Hemiptera: Reduviidae: Triatominae)
(2020-12-01)
Chagas disease, whose etiological agent is the protozoan Trypanosoma cruzi, affects millions of people worldwide and it is mainly transmitted by infected triatomine feces. Triatoma is the most diverse genus and one of the ...
