Standardization of laboratory bioassays for the study of Triatoma sordida susceptibility to pyrethroid insecticides. [PDF]

Parasit Vectors, 2015
BackgroundIncreasing reports of high-resistant Triatominae populations concerns scientists and sanitarians as little is known about the factors behind the occurrence of such phenotype and its real impact on vector control strategies.

Systematics of Triatoma sordida, T. guasayana and T. patagonica (Hemiptera, Reduviidae) [PDF]

Memórias do Instituto Oswaldo Cruz, 1993
Because of the relative epidemiological significance of Triatoma sordida, T. guasayana and T. patagonica, and the need to resolve doubts about their taxonomic validity, we report here a detailed taxonomic comparison of the three species using multivariate analysis of morphometric measures combined with comparisons of their genitalia and antennal ...

Wing geometry of Triatoma sordida (Hemiptera: Reduviidae) populations from Brazil.

Infection, Genetics and Evolution, 2017
Triatoma sordida has a widespread distribution in Argentina, Bolivia, Brazil, Paraguay, and Uruguay and is frequently found in peridomestic environments. We investigated size and shape variability of T. sordida wings across Brazil. Field-collected adults from twelve populations were studied. For each individual female, seven landmarks on the right wing

Correction: Post-Control Surveillance of Triatoma infestans and Triatoma sordida with Chemically-Baited Sticky Traps

PLoS Negl Trop Dis, 2012
خلفية: تعتمد الوقاية من مرض شاغاس بشكل حاسم على الحفاظ على المنازل خالية من ناقلات الترياتومين. رش المبيدات الحشرية فعال للغاية، لكن إعادة إصابة المساكن المعالجة أمر شائع. الكشف المبكر - القضاء على بؤر إعادة الإصابة هو مفتاح المكافحة على المدى الطويل ؛ ومع ذلك، فإن جميع طرق الكشف عن ناقلات الأمراض المتاحة لها حساسية منخفضة.

Trypanosoma cruzi infection in Triatoma sordida before and after community-wide residual insecticide spraying in the Argentinean Chaco [PDF]

Acta Tropica, 2015
Triatoma sordida is a secondary vector of Trypanosoma cruzi in the Gran Chaco and Cerrado eco-regions where it frequently infests peridomestic and domestic habitats. In a well-defined area of the humid Argentine Chaco, very few T.

Direct molecular identification of Trypanosoma cruzi discrete typing units in domestic and peridomestic Triatoma infestans and Triatoma sordida from the Argentine Chaco. [PDF]

Parasitology, 2012
SUMMARY We assessed the distribution of Trypanosoma cruzi Discrete Typing Units (DTUs) in domestic and peridomestic Triatoma infestans and Triatoma sordida specimens collected in a well-defined rural area in Pampa del Indio, northeastern Argentina ...

Susceptibility of Triatoma sordida Stal, 1859 (Hemiptera: Reduviidae) to alpha-cypermethrin under natural climatic conditions [PDF]

Revista da Sociedade Brasileira de Medicina Tropical, 2015
:INTRODUCTION:Despite the recommendations by interpretation of resistance ratios obtained in laboratory bioassays, little is known about the actual impact of these results in the effectiveness of vector control activities in the field.

Variability of susceptibility to deltamethrin in peridomestic Triatoma sordida from Triângulo Mineiro, State of Minas Gerais, Brazil

Revista da Sociedade Brasileira de Medicina Tropical, 2015
INTRODUCTION:Despite chemical and physical vector control strategies, persistent infestations of Triatoma sordida have been reported in a large part of Minas Gerais, Brazil, and the cause for this is little investigated.

Deltamethrin pyrethroid susceptibility characterization of Triatoma sordida Stål, 1859 (Hemiptera: Reduviidae) populations in the Northern Region of Minas Gerais, Brazil.

Revista Da Sociedade Brasileira De Medicina Tropical, 2014
INTRODUCTION Triatoma sordida is the most captured Triatomine species in the Brazilian artificial environment. In 2008, the discovery of three Triatomine populations with altered susceptibilities to deltamethrin highlighted the importance of ...
