Isolation of Trypanosoma freitasi (Kinetoplastida: Trypanosomatidae) from Psych...

Sand flies (Diptera, Psychodidae, Phlebotominae) from central amazonia and four...

Sand flies from Central Amazonia and four new records for the Amazonas state, Brazil. A survey was conducted in May and June 2008 to study the fauna of insects in Central Amazonia, Brazil. As part of the survey, we report here that sixty species of phlebotomine were identified, totaling 13,712 specimens from 13 genera. The collection sites were located at the border between the states of Pará and Amazonas, comp...

Lutzomyia derelicta (Diptera: Psychodidae) a Singular New Phlebotomine Sand Fly...

Lutzomyia derelicta n. sp. is described from specimens collected in an isolated xeric habitat in the rainforest in the north of the State of Pará, Brazil. The new species lacks the posterior bulge in the dorsal wall of the cibarium characteristic of the New World genus Lutzomyia, and the armature of the male genitalia is of the pattern found elsewhere only in the Old World species of Sergentomyia. L. derelicta ...

Current research on Amazonian triatominae.

Report on a Collection of Lutzomyia Sand Flies (Diptera: Psychodidae) from the ...

Fifty-two species of Lutzomyia sand flies were identified in contemporaneous samples totalling only 1875 individuals, collected at the same site in tall primary terra-firme rainforest, near the south bank of the Solimões River. The most abundant species belonged to the subgenera Trichophoromyia and Nyssomyia. The subgenera Psathyromyia, Nyssomyia and Psychodopygus represented the greatest number of species. A n...

Descriptions of Lutzomyia (Evandromyia) georgii n. sp. and a synopsis of the Se...

Lutzomyia georgii n. sp. and the female of L. tarapacaensis in the Series infraspinosa of the subgenus Evandromyia are described, from specimens collected in rainforest in the north of the State of Para, Brazil. The new species was taken together with five other Evandromyia species including L. infraspinosa (sensu strictu) in the same locality, I., georgii has previously been confused with both L. begonae and L...

Attraction of Chagas disease vectors (Triatominae) to artificial light sources ...

Adult triatomines occasionally fly into artificially lit premises in Amazonia. This can result in Trypanosoma cruzi transmission to humans either by direct contact or via foodstuff contamination, but the frequency of such behaviour has not been quantified. To address this issue, a light-trap was set 45 m above ground in primary rainforest near Manaus, state of Amazonas, Brazil and operated monthly for three con...

Trypanosomes of the subgenus Megatrypanum from armadillos (Xenarthra:Dasypodidae).

A new species of trypanosome, Trypanosoma (Megatrypanum) peba, is described from the peripheral blood of the armadillo Euphractus sexcinctus setosus from Bahia State, Brazil. Ten out of 29 specimens of the armadillo Dasypus novemcinctus from Pará State were found to have trypanosomes, including epimastigote forms, in impression smears of subcutaneous lymph nodes. The trypanosomes from D. novemcinctus are illust...

Species diversity and flagellate infections in the sand fly fauna near Porto Gr...

Forty-six species of Lutzomyia and one species of Brumptomyia were identified among 20,008 sand flies collected in central Amapá. L. squamiventris maripaensis, L. infraspinosa, L. umbratilis and L. ubiquitalis accounted for 66% of the specimens caught in light traps, and L. umbratilis was the commonest of the 16 species found on tree bases. Seven species of Lutzomyia including L. umbratilis were collected in a ...
