Insecticide spraying of housing units is an important control measure for vector-borne infections such as Chagas disease. However, some vectors may survive treatment, due to imperfect spraying by the operator or because they hide deep in the cracks or other places, and re-emerge in the same unit when the...
The main vectors of the Chagas disease in the Central America were Triatoma dimidiata, T. nitida and Rhodnius prolixus. The former two species inhabited cracks and crevice on the mud walls, especially closed to beds, while R. prolixus lived only inside thatched roofs, especially above beds. The parasitic...
Chagas disease (CD) persists as one of the neglected tropical diseases (NTDs) with a particularly large impact in the Americas. The World Health Organization (WHO) recently proposed goals for CD elimination as a public health problem to be reached by 2030 by means of achieving intradomiciliary transmissi...
La enfermedad de Chagas afecta a más de un millón y medio de personas en Argentina y es transmitida principalmente por la vinchuca Triatoma infestans (Klug, 1834). El control químico del vector con insecticidas piretroides constituye la herramienta más utilizada para reducir la incidencia de la enfer...
En América del Sur, Triatoma infestans es el principal insecto vector del parásitoTrypanosoma cruzi, agente etiológico de la enfermedad de Chagas (Tripanosomiasis Americana). En la actualidad, el control de Triatoma infestans se realiza principalmente mediante el rociado con insecticidas piretroides d...
Fluctuating asymmetry (FA), a phenotypic marker used as indicator of developmental stress or instability, is sometimes associated with insecticide application and resistance. Here we investigated the occurrence and amount of wing size and wing shape FA in Triatoma infestans females and males collected be...
A controlled clinical trial was carried out to assess the mortality and repellency of a new topical combination of f ipronil-permethrin (Effitix® Virbac, Mexico) against Rhodnius prolixus in dogs. Ten medium-size dogs (10−15kg) with short hair were used. The dogs were exposed to 8 adult triatomines on...

Although having five different ways of transmission the vector-borne is the principal way of transmission of Chagas disease, which involves insects of the subfamily Triatominae (Hemiptera: Reduviidae). Nineteen of the 31 species that occur in Mexico are associated with humans, and all are capable of tran...
The global resurgence of the bed bug (Cimex lectularius L.) and the widespread resistance of this insect to pyrethroid insecticides have created the need to find alternatives to chemical control. Thus, synthetic or natural repellents have been considered as a suitable choice to control bed bug infestatio...

Background: The detection of residual foci inside the houses, or the reinfestation of triatomines is one of the main entomological surveillance challenges. Actions aimed at increasing the probability of vector detection and to detect re-infestation when the density of vector populations is low, is a prio...
