Leishmaniose tegumentar americana: flebotomíneos em área de transmissão no Município de Uberlândia, MG

Abstract

From May 2000 to January 2001 four, 15 hour-long collections of phlebotomine were done to the insect monitoring. The collection was done in an area of infection of American cutaneous leishmaniasis in the basin of the Araguari River in the municipality of Uberlandia (MG). The first collection was made in May (a cold, damp month), the second in June 2000 (a cold, dry month) the third in October 2000 (a hot, dry month) and the fourth in January 2001 (a hot, rainy month). CDC and Shannon light traps were used 6551 phlebotomne were captured and identified, 1990 male and 4562 female, comprised of two lines (Lutzomyia and Brumptomyia) and 8 species. Lutzomyia intermedia predominated with the largest number of specimens (6531), which accounted for 99.7% of the collected insects. In the four collections, it was observed that Lutzomyia intermedia manifested a preference for the month preceding the rainy season, with its high temperatures and humidity.

Tegumentary leishmaniasis outbreak in Bella Vista City, Corrientes, Argentina during 2003

“…intermedia (from the same species complex as Lu. neivai) was the incriminated vector (Kawa & Sabroza 2002, Lemos & Lima 2005, Massafera et al 2005. The relative proportion of females and gravid females suggest breeding sites in the rural secondary vegetation, and potential colonization of peridomestic habitats in surrounding vegetation patches.…”

“…After this outbreak, the relative increased incidence of TL both children and females suggested a transmission shift from the forest to peridomestic habitats (Sosa Estani et al 2001, Sosa Estani & Salomon 2002. In addition, since the early 1980s the re-emergence of TL has been reported for many countries in the region, and urban transmission was proposed by many other investigators (Mott et al 1990, Desjeux 2001, Campbell-Lendrum et al 2001, Bejarano et al 2002, Leonardo & Rebêlo 2004, Lemos & Lima 2005.Lutzomyia intermedia sensu lato, currently termed Lu. neivai (Marcondes 1996), is widely distributed in the province of Corrientes.…”

Phlebotomine sand flies (Diptera: Psychodidae) of the state of Minas Gerais, Brazil

“…whitmani (Antunes & Coutinho) are those that deserves the most attention. Both species are suspected to be involved in the transmission of L. (V.) braziliensis in other parts of Brazil (Marcondes et al 1998, Andrade Filho et al 2007, Costa et al 2007, are highly anthropophilic, and are often present in foci of cutaneous leishmaniasis in Minas Gerais (Casanova 2001, Lemos & Lima 2005.…”

Flebotomíneos (Diptera: Psychodidae) coletados com armadilha malaise no Centro-Oeste de Minas Gerais

“…Vários trabalhos têm sido feitos com esses insetos na tentativa de se elucidar algumas questões relacionadas com sua ecologia, sazonalidade e importância na transmissão das leishmanioses (Andrade Filho et al 1998, Lemos & Lima 2005, Salomon & Orellano 2005.…”
