Further observations on Lutzomyia ubiquitalis (Psychodidae: Phlebotominae), the sandfly vector of Leishmania (Viannia) lainsoni

Phlebotominae sand flies (Diptera: Psychodidae): potential vectors of American cutaneous leishmaniasis agents in the area associated with the Santo Antônio Hydroelectric System in Western Amazonian Brazil

“…complexus are also likely involved in the transmission of agents of ACL in Brazilian Amazonia. Trichophoromyia ubiquitalis is the only sand fl y vector associated with the transmission of L. (V.) lainsoni (28) , a parasite recently identified in State of Rondônia (8) . However, Trichophoromyia species are also thought to be carriers of L. (V.) lainsoni, as deoxyribonucleic acid (DNA) of this parasite was found in Trichophoromyia auraensis specimens in the Peruvian Amazon (29) .…”

“…Although it has previously been suggested that Th. ubiquitalis does not exhibit high levels of anthropophilic behavior under field conditions (28) Nyssomyia umbratilis has been identifi ed as the main vector of L. (V.) guyanensis in northern Brazil, particularly in the Guianan ecoregion complex (31) . The fi ndings of the present study suggest that Ny.…”

Sand flies (Diptera, Psychodidae, Phlebotominae) from Central Amazonia and four new records for the Amazonas state, Brazil

“…Trichophoromyia ubiquitalis is widely distributed throughout the Amazon, and it has been described as an anthropophilic species, and incriminated as a vector of Leishmania (Viannia) lainsoni Silveira, Shaw, Braga & Ishikawa, 1987(Silveira et al 1991Lainson et al 1992). Females of most species of Trichophoromyia cannot be distinguished based on morphology and little is known about the bio-ecology of most species in this genus, while their role as potential vectors of ACL agent is unclear.…”

Ecology of the Leishmania Species in the Guianan Ecoregion Complex

“…It was also shown that it would feed on humans in the laboratory, as well as in the field, even if it did not appear to be an anthropophilic species. 199 The pathogenic complex of this parasite seems to develop at least in primary forests from northern Pará to French Guiana and it exists in other regions where the sand fly vectors and the reservoir hosts occur together.…”
