Cutaneous Leishmaniasis in Ceara State in Northeastern Brazil: Incrimination of Lutzomyia whitmani (Diptera: Psychodidae) as a Vector of Leishmania braziliensis in Baturite Municipality

The American Journal of Tropical Medicine and Hygiene, 1994
Baturite is an important endemic zone of American cutaneous leishmaniasis in the state of Ceara, where an entomologic survey has been carried out to obtain information about transmission of the disease. From October 1989 through August 1991, natural infections with flagellates were detected in 34 of 3,000 Lutzomyia whitmani, five of 1,667 Lu.

Domesticity of Lutzomyia whitmani (Diptera: Psychodidae) populations: field experiments indicate behavioural differences

Bulletin of Entomological Research, 2000
The sandfly Lutzomyia whitmani (Antunes & Coutinho) is an important vector for cutaneous leishmaniasis throughout much of Brazil, and has recently been shown to consist of more than one mitochondrial lineage. It has frequently been asserted that the degree of adaptation of L. whitmani to human environments varies across its range.

Genetic Variability in Geographical Populations ofLutzomyia whitmaniElucidated by RAPD-PCR

Journal of Medical Entomology, 2004
Unequivocal identification of phlebotomine sand flies is of crucial importance in epidemiological studies of leishmaniasis, because certain species may act as vectors, depending on behavior and physiology. For Lutzomyia whitmani, a major vector of American human cutaneous leishmaniasis in Brazil, an increasing number of studies have suggested the ...

Morphometric and Phenetic Studies of Five Geographical Populations ofLutzomyia whitmani(Diptera: Psychodidae) in Brazil

Journal of Medical Entomology, 1999
A morphometric survey examined adult specimens of Lutzomyia whitmani (Antunes & Coutinho) captured at 5 municipalities in southeastern and northeastern Brazil to compare the populations. The localities were Ilhéus (Bahia), Martinho Campos (Minas Gerais), Corte de Pedra (Bahia), Baturité (Ceará), and Amaraji (Pernambuco): all are known foci of American ...

Lutzomyia whitmani(Diptera: Psychodidae) as vector ofLeishmania (V.) braziliensisin Paraná state, southern Brazil

Annals of Tropical Medicine & Parasitology, 2000
The phlebotomine sandflies in the northern areas of the state of Paraná, Brazil, particularly those in the '16a' health region, were investigated over a 3-year period. Using CDC light traps (with and without hamster bait) and Shannon traps (with lights and horse or human bait), 16 species were collected from seven municipal districts which were known ...
