Toxicological profile of deltamethrin in Triatoma brasiliensis (Hemiptera: Redu...
Pessoa,Grasielle Caldas D'Ávila; Trevizani,Nathália Abreu Borges; Dias,Letícia Sena; Bezerra,Claudia Mendonça de; Melo,Bernardino Vaz deINTRODUCTION: Triatoma brasiliensis is the species of greatest epidemiological relevance in the semi-arid region of Brazil. This species is predominantly found in domestic environments, and it has the ability to build large colonies with high levels of natural infection via Trypanosoma cruzi. Thus, T. brasiliensis is one of the most efficient transmitters of Chagas disease (CD) to humans. Despite household spra...
Variability of susceptibility to deltamethrin in peridomestic Triatoma sordida ...
Pessoa,Grasielle Caldas DÁvila; Santos,Tamara Rodrigues Martins dos; Salazar,Gabriela Chadid; Dias,Letícia Sena; Mello,Bernardino Vaz deAbstractINTRODUCTION: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. We aimed to characterize the deltamethrin toxicological profile in peridomestic T. sordidapopulations from Triângulo Mineiro area of Minas Gerais.METHODS:Susceptibility to deltamethrin ...
Deltamethrin pyrethroid susceptibility characterization of Triatoma sordida Stå...
Pessoa,Grasielle Caldas DÁvila; Dias,Letícia Sena; Diotaiuti,LiléiaIntroduction 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 investigating the genetic potential for resistance in triatomines. The purpose of this study was to characterize the susceptibility to deltamethrin of peridomestic T. sordi...
