The sand fly fauna (Psychodidae: Phlebotominae) in the region of Saquarema, State of Rio de Janeiro, Brazil, an endemic area of cutaneous leishmaniasis transmission

Abstract

Cutaneous leishmaniasis, caused by Leishmania (Viannia) braziliensis, is sporadic in many rural and suburban areas of Rio de Janeiro State. An investigation was carried out during 2008/9 in the Municipality of Saquarema, Rio de Janeiro, Southeast Brazil, in order to identify the phlebotomine sand fly fauna. More than 2,100 sand flies were collected in peridomestic areas in two chicken coops using CDC light traps. Nine species of phlebotomine sand flies were identified: Nyssomyia intermedia, Nyssomyia whitmani, Pintomyia (P.) pessoai, Pintomyia (P.) fischeri, Pintomyia (P.) bianchigalatiae, Migonemyia (M.) migonei, Lutzomyia (L.) longipalpis, Brumptomyia cunhai and Brumptomyia guimaraesi. Based on the results of this study together with related studies in other CL foci in Rio de Janeiro, both Nissomyia intermedia and Migonemyia migonei can be considered suspect vectors of the disease in the region. The potential risk of VL due to the presence of its proven vector L. longipalpis is discussed. Journal of Vector Ecology 36 (Supplement 1): S95-S98. 2011.

The sandfly fauna (Diptera: Psychodidae: Phlebotominae) of the Parque Estadual da Serra da Tiririca, Rio de Janeiro, Brazil

“…All of the species found in this work have been recorded in other regions of RJ ( de Aguiar et al 1986 , Rangel et al 1990 , Brazil et al 1991, 2011 , Oliveira et al 1995 , Souza et al 2003 , Alves 2007 ). Evandromyia was the most abundant genus in the collections, represented by the species Ev.…”

“…Migonemyia was the second most abundant genus and was represented only by the species Mg. migonei , which was the second most frequent. This species is widely distributed in all regions of Brazil and it has been recorded throughout almost the entire RJ ( Rangel et al 1986 , Brazil et al 1991, 2011 , Souza et al 2002, 2003 ).…”

“…However, we emphasise that Mg. migonei was observed at in a higher density in this ecotope compared with the results of a recent study by our group performed in Saquarema. It was also one of the most abundant species around houses ( Brazil et al 2011 ). This finding agrees with those of Rangel and Lainson ( 2003 ), who showed that Mg. migonei displays a feeding habit characterised by a remarkable degree of anthropophily while also feeding on domestic animals, such as dogs.…”

Leishmaniasis transmission in an ecotourism area: potential vectors in Ilha Grande, Rio de Janeiro State, Brazil

“…Its sylvatic origin has been discussed elsewhere [ 1 ]. This suggests that, in Ilha Grande, L. (L.) longipalpis is probably more common in forest areas, as it was also found in other Atlantic Forest areas of Rio de Janeiro, Espírito Santo and São Paulo States [ 36 , 57 - 60 ].…”

Presence of Lutzomyia longipalpis (Diptera: Psychodidae) in the Parque Estadual da Serra da Tiririca, State of Rio de Janeiro, Southeastern Brazil

“…More recently, Brazil et al (8) and Rodrigues et al (9) showed the presence of Lu. longipalpis in transition areas of Atlantic Forest in Saquarema and Niterói, respectively.…”
