First report of Rhodnius neglectus (Hemiptera, Reduviidae, Triatominae) from the State of Acre, Brazil, and the Brazilian Western Amazon Region

Abstract

The occurrence of R. neglectus is alarming because even though the species is wild, it can invade and colonize human dwellings and peridomiciles, thereby increasing Chagas disease transmission.

Investigation of the triatomine (Hemiptera: Triatominae) fauna and its infection by Trypanosoma cruzi Chagas (Kinetoplastida: Trypanosomatidae), in an area with an outbreak of Chagas disease in the Brazilian South-Western Amazon

“…The specimens collected from palm trees were positive for T. cruzi. Similar data to this were found by other studies conducted in the state of Acre, where R. pictipes Stål, 1872 was collected in palm trees (Ramos et al 2018) and households (Ribeiro et al 2019), finding infection by T. cruzi in both environments. R. pictipes may also be associated with the first case of CD in the state of Amazonas (Fé et al 2009), having a high prevalence both in wild and households in the city of Manaus, where 73.9% of the total specimens were found (Fé et al 2009).…”

Retrospective study of the epidemiological overview of the transmission of Chagas disease in the State of Acre, South-Western Amazonia, from 2009 to 2016

“…Several studies show that most outbreaks of acute Chagas disease are associated with açaí [36][37][38][39] , which is the main food responsible for the increase in the number of cases of Chagas disease in the North region in recent years, whether due to fruit or pulp contamination by means of waste from the infected triatomines in the endemic areas 40 , which have already been registered in the state with the occurrence of the following species: Rhodnius robustus 29 , Rhodnius pictipes 29 , Rhodnius montenegrensis 41 , Rhodnius stali 16 , Rhodnius neglectus 42 , Eratyrus mucronatus 13 , Panstrongylus geniculatus 12 , Panstrongylus megistus 43 and Triatoma sordida 44 .…”

Differentiation of Rhodnius neglectus and Rhodnius prolixus (Hemiptera: Reduviidae: Triatominae) by multiple parameters

“…Lent, 1954 is considered a wild species and is largely distributed in Brazil (in Federal District and other 13 states: Acre, Bahia, Goiás, Maranhão, Mato Grosso, Mato Grosso do Sul, Minas Gerais, Paraíba, Pernambuco, Paraná, Piauí, São Paulo, Tocantins), being characteristic of the Cerrado biome. There are no occurrence records of R. neglectus outside the Brazilian territory where it has often invaded human habitations, with a secondary role in the transmission of Chagas disease 10,22 .…”
