Current spread of Triatoma infestans at the expense of Triatoma sordida in Bolivia
(Mem. Inst. Oswaldo Cruz, 1996)
Triatoma infestans is the most widespread synanthropic species of Triatominae and the most important vector of Chagas disease in South America. The progressive geographical expansion of this species from its silvatic focus ...
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 ...
Estudo morfológico e histológico dos ovos de seis espécies do gênero Triatoma (Hemiptera: Reduviidae)
(2007-09-01)
The objective of this study was to analyze the morphological and histological characteristics of eggs from six triatomine species in order to obtain a generic and specific characterization of this group of Trypanosoma cruzi ...
Cytogenetic study on three species of the genus Triatoma (Heteroptera: Reduviidae) with emphasis on nucleolar organizer regions
(2005-12-01)
The use of banding techniques allows the recognition of chromosomal pairs and karyotypical arrangements. However, its application in Heteroptera holocentric chromosomes is limited. Thus, little is known about their structure, ...
Comparison of feeding and defecation patterns between fifth-instar nymphs of Triatoma patagonica (Del Ponte, 1929) and Triatoma infestans (Klug, 1934) under laboratory conditionsComparação dos padrões alimentar e de defecação em ninfas de quinto estádio de Triatoma patagonica (Del Ponte, 1929) e Triatoma infestans (Klug, 1934), em condições de laboratório
(Sociedade Brasileira de Medicina Tropical, 2008-07)
Among the vectors of Chagas disease, Triatoma patagonica is a species in the process of adaptation to the human environment. However, its vector competence is not well known. This study had the aim of evaluating and comparing ...
Cytogenetic study of holocentric chromosomes in three species of triatomines (Heteroptera, Reduvidae)
(2004-03-01)
In the present work, spermatogenesis was analyzed in 3 species of the genus Triatoma (T. platensis, T. proctata, T. tibiamaculata). Lacto-acetic orcein staining was used in order to investigate chromosomal meiotic behavior ...
Misidentification of two Brazilian triatomes, Triatoma arthurneivai and Triatoma wygodzinskyi, revealed by geometric morphometrics
(WILEY-BLACKWELL, 2011)
Triatoma arthurneivai Lent & Martins and Triatoma wygodzinskyi Lent (Hemiptera: Reduviidae) are two Brazilian species found in the sylvatic environment. Several authors may have misidentified T. arthurneivai and consequently ...
Distribution of constitutive heterochromatin in two species of triatomines: Triatoma lenti Sherlock and Serafim (1967) and Triatoma sherlocki Papa, Jurberg, Carcavallo, Cerqueira & Barata (2002)
(2013-01-01)
Triatoma lenti and Triatoma sherlocki are hemipterans that belong to the brasiliensis subcomplex. In triatomines, the constitutive heterochromatin pattern is species-specific and allows, in many cases, for the grouping of ...
Detection of triatomine infection by Triatoma virus and horizontal transmission: Protecting insectaries and prospects for biological control
(Academic Press Inc Elsevier Science, 2015-01)
Triatoma virus (TrV) is the only triatomine entomopathogenic virus identified so far. Propagation of TrV in insectaries depends on handling procedures and triatomine population dynamics. The effects of propagation can be ...
