Phlebotomine sand flies (Diptera: Psychodidae) in the municipality of Várzea Grande: an area of transmission of visceral leishmaniasis in the state of Mato Grosso, Brazil
Missawa, Nanci Akemi;Dias, Edelberto Santos;
Memórias do Instituto Oswaldo Cruz , 2007, DOI: 10.1590/S0074-02762007000800004
Abstract: visceral leishmaniasis (vl) has been naturally transmitted in periurban areas due to the emergence and reemergence of its vectors in such areas. aimed to further knowledge on ecological aspects affecting the occurrence of phlebotomine sand flies in vl transmission areas in the municipality of várzea grande, state of mato grosso (mt), brazil, sand fly captures were carried out. monthly collections of sand flies were undertaken with cdc light-traps, which were left in both intradomiciliary and peridomiciliary areas of ten residences during four consecutive days between january 2004 and june 2006. twenty-two species of genus lutzomyia and one of brumptomyia were captured. the most abundant species was lutzomyia longipalpis (65.23%), followed by l. evandroi (16.26%), l. lenti (7.69%), l. whitmani (4.92%), l. sallesi (2.34%) and l. termitophila (1.32%). the highest density of the main vl vector, l. longipalpis, was found in peridomiciliary areas, mostly males. no significant correlation was found between environment (temperature, air relative humidity and rain fall) and phlebotomine density; although a slight increase in sand fly density has been observed in the period following rainfalls, particularly l. longipalpis. no correlation was observed between distribution and density of l. longipalpis, prevalence of human vl cases and the presence of serologically positive dogs. the presence of infected dogs, increased vector density, susceptibility rate and interruption of epidemiological surveillance may raise the risk of vl transmission to man in várzea grande.
Estudos sobre a fauna de Sarcophagidae (Diptera) de Belo Horizonte, Minas Gerais. III - atratividade das iscas
Dias, Edelberto Santos;Neves, David Pereira;Lopes, H. de Souza;
Memórias do Instituto Oswaldo Cruz , 1984, DOI: 10.1590/S0074-02761984000400003
Abstract: systematic collection of sarcophagidae was made between may 1980 and april 1981 with two types of traps and five different baits. twenty-five species were represented amingst the 9,592 specimens identified. the results are analysed to determine the attractiveness of different baits for sarcophagidae in general and for each of the species obtained. for the commonest species, attractiveness of baits is correlated to climatic conditions.

Memórias do Instituto Oswaldo Cruz , 1984, DOI: 10.1590/S0074-02761984000400002
Abstract: systematic capture of sarcophagidae was made over a period of one year (may, 1980 - april, 1981) in three different areas (urban, rural and silvatic), using two types of traps and five different baits. the total of 9,582 flies identified represented 25 especies. the monthly variations and seasonal abundance of each species are recorded.
Estudos sobre a fauna de Sarcophagidae (Diptera) de Belo Horizonte - Minas Gerais. I- Levantamento taxon?mico e Sinantrópico
Dias, Edelberto Santos;Neves, David Pereira;Lopes, H. de Souza;
Memórias do Instituto Oswaldo Cruz , 1984, DOI: 10.1590/S0074-02761984000100010
Abstract: over a period of one year (may, 1980 to april, 1981), systematic collections of sarcophagidae were made in three ecologically distinct areas of belo horizonte, minas gerais. two types of traps and five types of bait were used: raw fish, carcasses of mice, viscera of chickens, banana mashed with sugar, and human faeces. of the total of 10,097 specimens captured, the 9,582 studied included 25 species. indices of synanthropy (i.s.) for the 25 species varied considerably. the most synanthropic were parasarcophaga ruficornis (i.s. = + 94.7) and bercaea haemorrhoidalis (i.s. = + 84.3), and the least were euboettcheria florencioi (i.s. = - 98.8) and oxysarcodexia augusta (i.s. = - 96.9).

Abstract: a description is given of the female of lutzomyia amilcari, which was collected in cubiro, municipio diego de lozada, estado lara. the male of the same species was earlier described )arredondo, 1984).
Preferência alimentar de Lutzomyia longipalpis (Lutz & Neiva, 1912) em área de transmiss?o de leishmaniose visceral em Mato Grosso
Missawa, Nanci Akemi;Lorosa, Elias Seixas;Dias, Edelberto Santos;
Revista da Sociedade Brasileira de Medicina Tropical , 2008, DOI: 10.1590/S0037-86822008000400008
Abstract: studies on the feeding habits and intestinal content of sandflies make it possible to identify hosts, thereby indicating potential reservoirs for leishmania. the present study had the aim of determining the feeding preferences of lutzomyia longipalpis and its relationship with the transmission of visceral leishmaniasis. specimens were caught every month in a transmission area of visceral leishmaniasis, in the municipality of várzea grande, state of mato grosso, from january 2004 to june 2006, using cdc light traps. 2,376 females of lutzomyia longipalpis were caught, of which 104 (4.4%) were engorged. among these, 32 (30.8%) were caught inside homes and 72 (69.2%) in areas surrounding homes. from the precipitin reaction, it was observed that lutzomyia longipalpis females fed preferentially on birds (30.8%) and rodents (21.2%), but they were also found to have fed on blood from humans, opossums, oxen, horses and dogs, thus demonstrating the opportunist nature of this species.

Nota sobre Lutzomyia (Lutzomyia) Cruzi (mangabeira, 1938), com a descri??o da fêmea (Diptera, Psychodidae, Phlebotominae)
Martins, A. Vianna;Falc?o, Alda Lima;Silva, Jo?o Evangelista da;Dias, Edelberto Santos;
Memórias do Instituto Oswaldo Cruz , 1984, DOI: 10.1590/S0074-02761984000400007
Abstract: after examining the type of lutzomyia (lutzomyia) cruzi (mangabeira, 1938), kept in the collection of the instituto oswaldo cruz (rio de janeiro), under number 941, and 74 male specimens of the species, mostly from the type locality (camapuan, state of mato grosso do sul), the authors verified that the basal tuft of the coxite is composed of only four foliaceous setae, and not six, as stated by mangabeira, due the superposition of the two coxites holotype. a redescription of the male based on the holotype and a description of the previously unknown female are presented.
