Monitoring Rhodnius neglectus (Lent, 1954) populations’ susceptibility to insec...
Silva,Rubens Antonio da; Maldonado,Lis Adriana; Pessoa,Grasielle Caldas D’Ávila; Diotaiuti,LiléiaABSTRACT Background: Chagas disease (CD) is caused by the flagellate protozoan Trypanosoma cruzi and can be carried by different species of triatomines, including Rhodnius neglectus, which is wild, well distributed in Brazil, and has formed colonies in palm trees located in urban areas of municipalities in the state of São Paulo. Chemical control has been routinely used to reduce population density, but each ye...
Synanthropic triatomines (Hemiptera: Reduviidae): infestation, colonization, an...
Barbosa-Silva,Andressa Noronha; Souza,Rita de Cássia Moreira de; Diotaiuti,Liléia; Aguiar,Lúcia Maria Abrantes; Câmara,Antonia Cláudia Jácome daAbstract INTRODUCTION The ecoepidemiological situation in the State of Rio Grande do Norte, Brazil is characterized by frequent invasion and colonization of domiciliary units (DUs) by several triatomine species, with high rates of natural infection by Trypanosoma cruzi. METHODS: We evaluated the possibility of vector transmission of T. cruzi based on records of the occurrence of domiciled triatomines collected ...
Conhecimentos sobre triatomíneos e sobre a doença de Chagas em localidades com ...
Dias,João Victor Leite; Queiroz,Dimas Ramon Mota; Diotaiuti,Liléia; Pires,Herton Helder RochaResumo A participação comunitária é a principal estratégia para a manutenção da vigilância entomológica da doença de Chagas. O objetivo deste estudo foi avaliar conhecimentos sobre triatomíneos e a doença de Chagas entre moradores de oito localidades de Diamantina, Minas Gerais, atentando a uma eventual relação entre os conhecimentos e a infestação vetorial. Para avaliação dos conhecimentos foi aplicado questio...
Susceptibility characterization of residual Brazilian populations of Triatoma i...
Pessoa,Grasielle Caldas D`avila; Rosa,Aline Cristine Luiz; Bedin,Cleonara; Wilhelms,Tânia; Mello,Fernanda de; Coutinho,Helder SilveiraINTRODUCTION: Despite years of efforts towards the elimination of Triatoma infestans in Brazil, residual foci still persist in some areas of the States of Bahia and Rio Grande do Sul. The persistence of these T. infestans populations in the country has two different origins of equal concern: operational failures or insecticide resistance. Thus, the objective of this study was to characterize the susceptibility ...
History of insecticide resistance of Triatominae vectors
Pessoa,Grasielle Caldas Dávila; Vinãs,Pedro Albajar; Rosa,Aline Cristine Luiz; Diotaiuti,LiléiaAbstractIn 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 articles from 1970 to 2015 in the PubMed database that contained the keywords Insecticide resistance ...
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 ...
Susceptibility of Triatoma sordida Stal, 1859 (Hemiptera: Reduviidae) to alpha-...
Pessoa,Grasielle Caldas DÁvila; Rosa,Aline Cristine Luiz; Cavalari,Letícia; Rezende,João Geraldo de; Mello,Bernardino Vaz de; Diotaiuti,LiléiaAbstract: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. In this context, our objective was to determine the mean value of different resistance ratios obtained by laboratory bioassays performed as part of the chemical control s...
Evaluation of the Chagas Disease Control Program in Açucena Municipality, Rio D...
Santos,Adriana dos; Letro,Rejane Balmant; Lemos do Bem,Vitor Antônio; Azeredo,Bernardino Vaz de Melo; Coelho,George Luiz Lins Machado; Diotaiuti,LiléiaIntroduction Açucena Municipality, Rio Doce Valley, State of Minas Gerais, Brazil temporarily (2001-2005) interrupted epidemiological surveillance for Chagas disease. The objective of this work was to evaluate the Chagas Disease Control Program (CDCP) in Açucena and to offer suggestions for improving local epidemiological surveillance. Methods This study was conducted in three phases: I) a serological investiga...
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...
Species of the subfamily Triatominae Jeannel, 1919 (Hemiptera: Reduviidae) pres...
Souza,Rita de Cássia Moreira de; Brito,Raissa Nogueira; Barbosa,Anatiele Borges; Diotaiuti,LiléiaIntroduction Biological collections are depositories of information on different species and contribute to the knowledge, protection, conservation and maintenance of biodiversity. Methods A list of triatomine species currently included in the Collection of Chagas Disease Vectors (FIOCRUZ-COLVEC) was prepared from the database made available by the Reference Center on Environmental Information. Results COLVEC cu...
