Chagas' disease in the Amazon Basin: V. Periurban palms as habitats of Rhodnius robustus and Rhodnius pictipes - triatomine vectors of Chagas' disease

Abstract: Trypanosoma cruzi infected Rhodnius robustus and/or Rhodnius pictipes were commonly found, in large numbers, in the Brazilian Amazonian palms Maximiliana regia ("inajá"), Acrocomia sclerocarpa ("mucajá") and Orbignya speciosa ("babaçu"). The common opossum, Didelphis marsupialis, was the animal most frequently associated with triatomine infested palms. R. pictipes, frequently light-attracted into houses from palm trees, was the probable source of an acute case of Chagas' disease in the vicinity of Belém. It is… Show more

“…In order to identify the specimen, Floch used the works of Larrousse (1927) and Neiva and Lent (1941), which did not allow for a rigorous distinction between R. prolixus and R. robustus. Later, Chippaux et al (1985) again listed R. prolixus in French Guiana, despite Miles' opinion (Miles et al 1983); Miles had doubts as to the presence of the species in French Guiana and he assigned the specimens identified by Chippaux to R. robustus [Miles in litt. cited by Chippaux et al (1985)].…”

“…e Rhodnius robustus Larrousse, 1927 são espécies de triatomíneos predominantemente silvestres, habitando diferentes espécies de palmeiras no Brasil [1][2][3][4][5] . R. neglectus é uma espécie característica do cerrado no Brasil central com um papel importante na transmissão enzoótica de Trypanosoma cruzi e T. rangeli 6 .…”

“…Além da invasão de adultos nos domicílios 7 , existem evidências de formação de colônias domiciliares de R. neglectus nos Estados de Minas Gerais, São Paulo e Goiás [8][9][10] , sendo considerado como um vetor secundário na transmissão da doença de Chagas. R. robustus (s.l., ver Abad-Franch cols 4 ) tem ampla distribuição na Amazônia, ocorrendo frequentemente em palmeiras (silvestres e periurbanas) em altas densidades e com relevantes taxas de infecção por tripanosomatídeos 1,3,11,12 . Apesar de não existirem evidências de colonização de R. robustus em ambiente domiciliar no Brasil, espécimes adultos infectados por T. cruzi têm invadido casas na região amazônica, sendo potenciais vetores extradomiciliares ou ainda podendo contaminar equipamentos de processamento de alimentos, representando risco de transmissão oral da doença de Chagas 13,14 .…”
