Chagas disease is caused by the parasite Trypanosoma cruzi and transmitted by multiple triatomine vectors across the Americas. In Central America, the predominant vector is Triatoma dimidiata, a highly adaptable and genetically diverse Hemiptera. In this research, we used a novel reduced-representation D...
Diversos trabalhos foram realizados ao longo da história do Brasil com o intuito de se controlar e erradicar os bichos barbeiros do ambiente habitado por seres humanos, incluindo a realização de controle químico com hexaclorociclohexanos. O objetivo desta pesquisa foi avaliar a ...
We investigated the dynamics and underlying causes of house (re)infestation with Triatoma infestans (Klug 1834) after a community-wide residual spraying with pyrethroids in a well-defined rural section of Pampa del Indio municipality (northeastern Argentina) over a 4-yr period. House infestation was asse...
Abstract
Background: Chagas disease is one of the neglected tropical diseases (NTDs). International goals for its control
involve elimination of vector-borne transmission. Central American countries face challenges in establishing
sustainable vector control programmes, since the main vector, Triatoma dim...

The domiciliary presence of Triatoma infestans (Klug) (Hemiptera: Reduviidae) after control interventions was reported in recent years. Toxicological studies showed high levels of resistance to pyrethroids suggesting resistance as one of the main causes of deficient control. The aim of the present study ...
Background
Insecticide spraying efficiently controls house infestation by triatomine bugs, the vectors of Trypanosoma cruzi. The strategy, however, is ineffective against sylvatic triatomines, which can transmit Chagas disease by invading (without colonizing) man-made structures. Despite growing awarenes...
Monoterpenes are the main components of essential oils. Some members of this chemical family present insecticidal activity. Triatoma infestans (Klug) is the main vector of Chagas disease in Argentina, Bolivia, Paraguay, and Perú. The objective of this work was to evaluate the effect of six monoterpenes ...

Background
Despite large-scale reductions in Chagas disease prevalence across Central and South America, Trypanosoma cruzi infection remains a considerable public health problem in the Gran Chaco region where vector-borne transmission persists. In these communities, peridomestic animals are major blood-m...
Resumen:Los efectos de los insecticidas sobre las abejas han cobrado gran atención a nivel mundial, sin embargo, son pocos los estudios sobre el efecto de estos agroquímicos en abejas Neotropicales. Bombus atratus es una especie neotropical, distribuida ampliamente en los Andes y es considerado un poli...

Abstract: INTRODUCTION: Dengue fever is a viral disease transmitted by the Aedes aegypti Linn. (1792) (Diptera: Culicidae) mosquito, which is endemic in several regions of Brazil. Alternative methods for the control of the vector include botanical insecticides, which offer advantages such as lower envir...
