(Instituto Oswaldo Cruz, 2006)In light of the Central American Initiative for the control of Chagas disease, efforts were made on the part of Costa Rican and Nicaraguan teams, working separately, to determine the present status of Rhodnius pallescens ... -
Ecological control of Triatoma dimidiata (Latreille, 1811): five years after a Costa Rican pilot project
(Instituto Oswaldo Cruz, 2008)An ecological pilot project for the control of Triatoma dimidiata allowed a new evaluation four and five years after environmental modifications in the peridomestic areas of 20 households. It was verified that the two ... -
Ecological patterns of blood-feeding by kissing-bugs (Hemiptera: Reduviidae: Triatominae)
(Instituto Oswaldo Cruz, 2011-06)Host use by vectors is important in understanding the transmission of zoonotic diseases, which can affect hu mans, wildlife and domestic animals. Here, a synthesis of host exploitation patterns by kissing-bugs, vectors of ... -

Entomological and Ecological Aspects of Six Sylvatic Species of Triatomines (Hemiptera, Reduviidae) from the Collection of the National Biodiversity Institute of Costa Rica, Central America
(Memórias do Instituto Oswaldo Cruz, 2001)A total of 797 specimens of wild adult triatomines, belonging to six species from the entomological collections of the Costa Rican National Biodiversity Institute, was studied from the standpoint of their relative ... -
Environmental management for the control of Triatoma dimidiata (Latreille, 1811), (Hemiptera: Reduviidae) in Costa Rica: a pilot project
(Memórias do Instituto Oswaldo Cruz, 2006-06)An ecological control method, using environmental management operations, based on biological and behavioral characteristics of Triatoma dimidiata (Latreille, 1811), was implemented as a pilot project in an area of Costa ... -
Epidemiological, social, and control determinants of Chagas disease in Central America and Mexico - Group discussion
(Memórias do Instituto Oswaldo Cruz, 2007)The existence of Chagas disease in Central America was reported for the first time in El Salvador in 1913, four years after its discovery in Brazil. At that time only Triatoma dimidiata was known as a vector, but two ... -
