Lutzomyia (Nyssomyia) whitmani s.l . (Antunes & Coutinho, 1939)(Diptera: Psychodidae: Phlebotominae): geographical distribution and the epidemiology of American cutaneous leishmaniasis in Brazil Mini-review [PDF]

Memórias do Instituto Oswaldo Cruz, 2007
The aim of the present study, in view of the widespread geographical distribution of Lutzomyia (Nyssomyia) whitmani s.l. in Brazil, in close association with the regions of transmission of Leishmania (Viannia) braziliensis and L. (V.) shawi, is to investigate the distribution of this sand fly species and American cutaneous leishmaniasis (ACL) in ...

Distribution and Abundance of Phlebotominae, Vectors of Leishmaniasis, in Argentina: Spatial and Temporal Analysis at Different Scales [PDF]

Journal of Tropical Medicine, Volume 2012, Issue 1, 2012., 2012
The spatial-temporal analysis of the abundance of insects, vectors of tegumentary leishmaniasis (TL) and visceral leishmaniasis (VL),was performed in Argentina using spatial-temporal increasing scales.In the microscale(microfocal), the effect of the ...

Molecular polymorphism, differentiation and introgression in the period gene between Lutzomyia intermedia and Lutzomyia whitmani. [PDF]

BMC Evol Biol, 2006
AbstractBackgroundLutzomyia intermediaandLutzomyia whitmani(Diptera: Psychodidae) are important and very closely related vector species of cutaneous leishmaniasis in Brazil, which are distinguishable by a few morphological differences. There is evidence of mitochondrial introgression between the two species but it is not clear whether gene flow also ...

Association between the potential distribution of Lutzomyia longipalpis and Nyssomyia whitmani and leishmaniasis incidence in Piauí State, Brazil. [PDF]

PLoS Negl Trop Dis, 2023
Background Leishmaniases are vector borne diseases caused by Leishmania spp. parasites transmitted by female sandflies (Diptera: Psychodidae) whose geographic distribution is influenced by environmental factors. Among the main tools for studying the distribution of vector species, modeling techniques are used to analyze the influence of climatic and ...

A periurbanização de Lutzomyia whitmani em área de foco de leishmaniose cutânea, no Estado do Maranhão, Brasil [PDF]

Revista da Sociedade Brasileira de Medicina Tropical, 2004
Em um inquérito entomológico realizado em 2000, na zona periurbana do município de Dom Pedro-MA, pretendia-se estimar a abundância de Lutzomyia longipalpis, por conta da ocorrência de um óbito suspeito de calazar. Entretanto, constatou-se que do total de

Species, Natural <i>Leishmania</i> spp. Detection and Blood Meal Sources of Phlebotomine Sandflies (Diptera: Psychodidae: Phlebotominae) in Peridomiciles from a Leishmaniases Endemic Area of Brazil. [PDF]

Transbound Emerg Dis
Leishmaniases are important neglected tropical diseases caused by protozoans of the genus Leishmania spp. The female sandflies bite (Diptera: Psychodidae: Phlebotominae) is the main transmission form in the epidemiological chains of these diseases.

Trypanosomatid infections in captive wild mammals and potential vectors at the Brasilia Zoo, Federal District, Brazil

Veterinary Medicine and Science, Volume 6, Issue 2, Page 248-256, May 2020., 2020
Conservation projects in zoos require translocations of captive animals, which may spread pathogens. We aimed to verify the occurrence of vectors (triatomines and sandflies) and to investigate Trypanosoma cruzi and Leishmania infections in captive wild mammals in the Zoo Brasília.

Species structure of sand fly (Diptera: Psychodidae) fauna in the Brazilian western Amazon

Memorias do Instituto Oswaldo Cruz, 2009
We surveyed areas of the state of Rondônia in western Amazon for phlebotomine, which are potential vectors of leishmaniasis. A total of 5,998 specimens were captured, resulting in the identification of 48 species within the Lutzomyia (99.98%) and ...
