Insecticidal efficacy of fluralaner (Bravecto®) against Triatoma brasiliensis, a major vector of Trypanosoma cruzi in Brazil

Parasitas e Vetores BMC; 14 (456), 2021
Background: Triatomines are responsible for the vector transmission of the protozoan parasite Trypanosoma cruzi, which causes Chagas disease. Triatoma brasiliensis is the main vector of the parasite in Brazil, and dogs are an important reservoir of the parasite. The aim of this study was to evaluate the ...

Improved vector control of Triatoma infestans limited by emerging pyrethroid resistance across an urban-to-rural gradient in the Argentine Chaco

Parasitas e Vetores BMC; 14 (437), 2021
Background: The sustainable elimination of Triatoma infestans in the Gran Chaco region represents an enduring challenge. Following the limited effects of a routine pyrethroid insecticide spraying campaign conducted over 2011–2013 (first period) in Avia Terai, an endemic municipality with approximately ...

Phenotypic plasticity, canalisation and developmental stability of Triatoma infestans wings: effects of a sublethal application of a pyrethroid insecticide

Parasitas e Vetores BMC; 14 (355), 2021
Abstract Background: Triatomine control campaigns have traditionally consisted of spraying the inside of houses with pyrethroid insecticides. However, exposure to sublethal insecticide doses after the initial application is a common occurrence and may have phenotypic consequences for survivors. Here, usi...

History of insecticide resistance of Triatominae vectors

Parasit. vectors; 14 (98), 2021
In the last 15 years, different types of Triatominae resistance to different insecticides have been reported; thus, resistance may be more widespread than known, requiring better characterization and delimitation, which was the aim of this review. This review was structured on a literature search of all ...

Biogeographical factors determining Triatoma recurva distribution in Chihuahua, México, 2014

Biomédica (Bogotá); 40 (3), 2020
Introduction: Triatoma recurva is a Trypanosoma cruzi vector whose distribution and biological development are determined by factors that may influence the transmission of trypanosomiasis to humans. Objective: To identify the potential spatial distribution of Triatoma recurve, as well as social factors d...

Cytotaxonomy of Dipetalogaster maxima Uhler, 1894 (Hemiptera, Reduviidae, Triatominae)

Braz. j. biol; 80 (2), 2020
Abstract The Triatomini tribe consists of ten genera and is regarded as one of the most important tribes from epidemiological point of view. The genus Dipetalogaster Usinger, 1939 is composed only by the species Dipetalogaster maxima Uhler, 1894. This triatomine is exclusive of the Mexico and is a potent...

Caracterização epidemiológica e distribuição geográfica de potenciais vetores da doença de Chagas na região do Maciço de Baturité, Ceará, Brasil

Objetivo: identificar potenciais vetores da doença de Chagas na região do Maciço de Baturité, Ceará. Métodos: no período de2014 a 2018, foi realizado estudo parasitológico em fezes de triatomíneos para Trypanosoma cruzi, em oito municípios da região do maciço de Baturité. Os triatomíneos fo...

Triatomine bugs (Hemiptera, Reduviidae, Triatominae) in the Domiciles of the Guaribas Valley Territory, in Northeastern Brazil

Abstract INTRODUCTION Triatomine bugs are hematophagous insects that are extremely important in public health because they are natural vectors of Trypanosoma cruzi, the causative agent of Chagas disease. In this study, we aimed to assess the occurrence of triatomine species and the natural T. cruzi inf...

New report of Eratyrus cuspidatus Stål, 1859 (Hemiptera: Reduviidae: Triatominae) in the State of Campeche, Mexico

Abstract INTRODUCTION: Triatomine bugs are vectors of Trypanosoma cruzi, the etiological agent of Chagas disease. METHODS: Triatomine bugs were collected and identified following established protocols. In addition, infection with T. cruzi was detected by microscopic and molecular analysis. RESULTS: We...
