SEXUAL DISTINCTION BETWEEN 5TH INSTAR NYMPHS OF 6 SPECIES OF TRIATOMINAE (HEMIPTERA, REDUVIIDAE)
(Mem Inst Oswaldo Cruz, 1992-04-01)
The aim of this paper is to present the analysis of sexual morphological differences observed in 5th instar nymphs of the following species: Panstrongylus megistus; Rhodnius neglectus; Triatoma brasiliensis; T. infestans; ...
Acid phosphatase activity distribution in salivary glands of triatomines (Heteroptera, Reduviidae, Triatominae)
(Funpec-editora, 2007-01-01)
Acid phosphatase activity (Gomori technique) in salivary gland cells was investigated in adult insects (males and females) of four species of triatomines: Triatoma infestans, Panstrongylus megistus, Rhodnius neglectus, and ...
Spermatogenesis in Triatoma williami Galvao, Souza and Lima (1965) (Hemiptera, Triatominae)
(Taylor & Francis Ltd, 2014-04-03)
Cytogenetics has proven to be an important tool in the study of triatomine taxonomy. Triatoma williami is a triatomine that has been classified within the Matogrossensis subcomplex. In this study, the cytogenetic technique ...
Heteropyknotic filament in spermatids of Triatoma melanocephala and T. vitticeps (Hemiptera, Triatominae)
(Taylor & Francis Ltd, 2014-01-01)
The species Triatoma melanocephala and T. vitticeps are vectors of Chagas disease in Brazil. An analysis of the number of chromosomes has led to the proposal of the exclusion of both these species and T. tibiamaculata from ...
A new species of rhodnius from Brazil (Hemiptera, reduviidae, triatominae)
(2017-01-01)
A colony was formed from eggs of a Rhodnius sp. female collected in Taquarussu, Mato Grosso do Sul, Brazil, and its specimens were used to describe R. taquarussuensis sp. n. This species is similar to R. neglectus, but ...

Introduction: This article reports, for the first time, the occurrence of Panstrongylus megistus in the Brazilian Western Amazon.& para;& para;Methods: Specimens of P. megistus were collected in the cities of Rio Branco, ...
Alkaline phosphatase activity in salivary gland cells of Rhodnius neglectus and R-prolixus (Hemiptera, Triatominae)
(Funpec-editora, 2016-01-01)
Alkaline phosphatase activity was detected in salivary gland cells of the Rhodnius neglectus Lent, 1954, and R. prolixus Stal, 1859, vectors of Trypanosoma cruzi Chagas, 1909 (etiological agent of Chagas disease) and T. ...
Distribution of constitutive heterochromatin in Triatoma melanocephala (Hemiptera, Triatominae)
(Funpec-editora, 2014-01-01)
In principle, Triatoma melanocephala was included in the Brasiliensis subcomplex on the basis of morphological parameters and geographical layout, since there were no other relevant data available in the literature. On the ...
MORPHOLOGY OF ABDOMINAL BRISTLES DETERMINED BY SCANNING ELECTRON-MICROSCOPY IN 6 SPECIES OF TRIATOMINAE (HEMIPTERA, REDUVIIDAE)
(Mem Inst Oswaldo Cruz, 1995-07-01)
Can body traits, other than wings, reflect the flight ability of Triatominae bugs?
(Soc Brasileira Medicina Tropical, 2015-09)
Triatominae insects are vectors for Trypanosoma cruzi, the Chagas disease parasite, and their flying behaviour has epidemiological importance. In Triatominae, the flying capacity shows striking differences among species, ...
