13. Description of a new phlebotomine species, Martinsmyia reginae sp. nov. (Diptera: Psychodidae: Phlebotominae) from a cave in the state of Tocantins Brazil
As inhabitants of forested areas, caves and anthropic environments, the phlebotomines deserve special attention because some species are able to transmit trypanosomatids, bacteria and viruses to vertebrates. Phlebotomines are also a nuisance because they cause painful bites, which may ultimately produce allergic manifestations. The lack of information about

14. Caracterização do mecanismo de controle do pH no tubo digestivo de Lutzomyia longipalpis (Lutz e Neiva, 1912) (Diptera: Psychodidae) e sua importância no desenvolvimento de Leishmania Ross, 1903
The midgut pH control is a key step during Lutzomyia longipalpis digestion process. Phlebotomines have to change from a favorable carbohydrate digestion (luminal pH = 6) to blood digestion (luminal pH~8). Until blood ingestion, the acidic pH in the midgut is rigorously maintained closely to pH 6 by an efficient mechanism. Apparently, alkalization in the abdo

Aspectos ecológicos da fauna flebotomínea (Diptera, Psychodidae) do Parque Estadual da Cantareira (PEC) e Parque Estadual Alberto Löfgren (PEAL) região metropolitana de São Paulo, Estado de São Paulo, Brasil / Ecological aspects of the phlebotomines (Diptera, Psychodidae) from the Parque Estadual da Cantareira (PEC) and Parque Estadual Alberto Löfgren (PEAL) metropolitan region of Sao Paulo City, São Paulo State, Brazil
Introdução. As leishmanioses são doenças infecciosas, causadas por protozoários do gênero Leishmania, transmitidos por insetos da subfamília Phlebotominae (Diptera, Psychodidae). No Estado de São Paulo a incidência da leishmaniose tegumentar americana (LTA) e da leishmaniose visceral americana (LVA) está aumentando tanto em regiões rurais como urb

17. The first report of the main vector of visceral leishmaniasis in America, Lutzomyia longipalpis (Lutz & Neiva) (Diptera: Psychodidae: Phlebotominae), in the state of Rio Grande do Sul, Brazil
Visceral leishmaniasis (VL) is a widespread zoonosis in Brazil and, up to now, there has been no record of the main vector of its agent, Lutzomyia longipalpis, in the Southern Region. Due to the diagnosis of VL in a dog in October 2008 in the city of São Borja, in the southernmost Brazilian state of Rio Grande do Sul, a collection of phlebotomines was under

18. Dispersal and survival of Nyssomyia intermedia and Nyssomyia neivai (Diptera: Psychodidae: Phlebotominae) in a cutaneous leishmaniasis endemic area of the speleological province of the Ribeira Valley, state of São Paulo, Brazil
The dispersal and survival of the phlebotomines Nyssomyia intermedia and Nyssomyia neivai (both implicated as vectors of the cutaneous leishmaniasis agent) in an endemic area was investigated using a capture-mark-release technique in five experiments from August-December 2003 in municipality of Iporanga, state of São Paulo, Brazil. A total of 1,749 males an

19. Studies on the sandfly fauna (Diptera: Psychodidae: Phlebotominae) from transmission areas of American Cutaneous Leishmaniasis in state of Acre, Brazil
Studies were undertaken on the phlebotomines in the municipalities of Bujari, Xapuri and Rio Branco in the state of Acre. The abundance of species on the ground and in the tree canopy was estimated by Standardized Index of Species Abundance. Of the 52 species identified, Lutzomyia (N.) antunesi, Lutzomyia (N.) whitmani, Lutzomyia (P.) davisi, Lutzomyia migon

20. Leishmaniose Visceral Americana: Análise das estratégias de controle da doença na micro-região de Dracena na Alta Paulista/SP Brasil / American Visceral Leishmaniasis Control Strategics of the Disease in the Microregion of Dracena in Alta Paulista/SP Brazil
The American Visceral Leishmaniasis (LVA) has been spreading in a short period of time with deep concern for all West of São Paulo State, instead of the measures that have been taken to control it. This search was made in order to study the variability involved in the disease cycle, as well as the efficacy of the measures to control it. The study involved t

21. American cutaneous leishmaniasis on the northern coast of São Paulo state, Brazil, 1993 to 2005. / Leishmaniose tegumentar americana no litoral norte paulista, período 1993 a 2005
Introduction. The northern coast of the State of São Paulo was, up to the decade of the 1980´s, hypoendemic for the transmission of American cutaneous leishmaniasis (ACL). However, as from the decade of the 1990´s this disease acquired epidemic characteristic in all the municipalities: Caraguatatuba, Ilhabela, São Sebastião and Ubatuba. Objective. To un

22. Phlebotomines (Diptera: Psychodidae) in forested areas of the Serra da Bodoquena, state of Mato Grosso do Sul, Brazil
Investigation was undertaken on the behaviour of the phlebotomine fauna in caves, forests, and anthropic environments of the Serra da Bodoquena, between January 1998 and January 2000. This paper reports on the phlebotomines captured in forested areas with automatic light traps (ALT), Shannon traps (ST), aspiration (AN), at natural resting sites and by human

23. Estudos epidemiológicos em área de leishmaniose tegumentar no município de Bela Vista, Estado de Mato Grosso do Sul, Brasil
The epidemiological studies undertaken permitted the isolation and identification of Leishmania (Leishmania) amazonensis in patients from the municipality of Bela Vista, Mato Grosso do Sul State, Brazil, thus expanding our knowledge of this parasites distribution. The captures of phlebotomines were undertaken from February 2004 to January 2006, using automat

24. Impact of leishmaniasis on public health
Leishmaniasis is a parasitic zoonosis caused by protozoans of the genus Leishmania transmitted by insects known as phlebotomines, which are found in wild or urban environments. It affects domestic and wild animals and transmission to man happens by accident. The disease occurs in tropical and sub-tropical areas, mainly in Asia, Europe, Africa, and the Americ
