First report of Eratyrus mucronatus, Stal, 1859, (Hemiptera, Reduviidae, Triatominae), in the State of Rondônia, Brazil

Abstract

Introduction: This paper reports, for the first time, the presence of the Eratyrus mucronatus species in the State of Rondonia, Brazil. Methods: These specimens were caught by chance in the forest and later they were collected using luminous traps. Results: After finding these specimens, the number of the Triatominae genera in Rondonia rose to four, while its species rose to seven. Conclusions: Complimentary studies will be conducted in order to allow for clearer understanding the ecology of this arthropod, its possible role in transmitting Chagas' disease and its current geographical distribution.

First report of Rhodnius stali (Hemiptera, Reduviidae, Triatominae) in the State of Acre and in the Brazilian Amazon

“…In the Brazilian Amazon, at least 20 species of sylvatic triatomines belonging to eight genera have been identified, of which more than 10 are related to infection by the flagellate Trypanosoma cruzi (6) (7) . In the state of Acre, there have been reports of five triatomine species belonging to three genera, namely: Rhodnius montenegrensis (2) , Rhodnius robustus (8) , Rhodnius pictipes, Panstrongylus geniculatus (6) , and Eratyrus mucronatus (9) .…”

First report of Rhodnius montenegrensis (Hemiptera, Reduviidae, Triatominae) in the State of Acre, Brazil

“…In Brazil, there are eight genera of Triatominae: Alberprosenia, Belminus, Cavernicola, Eratyrus, Microtriatoma, Panstrongylus, Parabelminus, Psammolestes, Rhodnius, and Triatoma (5) (6) . In the State of Acre, researchers have reported the occurrence of four species of triatomines, namely, Rhodnius robustus (7) , Rhodnius pictipes, Panstrongylus geniculatus (8) , and Eratyrus mucronatus (9) .…”

First report of Rhodnius montenegrensis (Hemiptera: Reduviidae: Triatominae) infection by Trypanosoma rangeli

“…A total of 120 triatomines were collected, providing an average of 8.6 specimens per Attalea speciosa, which is below the average reported by other studies in the state 9,11 . Of those triatomines, only 13 (10.8%) were adults, and all were R. montenegrensis.…”

“…This possibility is concerning, especially in a state where there are reports of other vector species of T. rangeli, such as R. pictipes and R. robustus 11,12 . …”

“…The latter species may have been erroneously described in the State of Rondônia by some researchers 11,12 because of its similarity to R. montenegrensis, which had not been described at that time.…”
