Durante dois anos foi feito um estudo ecologico sobre os flebotomineos em foco de leishmaniose cutânea em Itaguai, Estado do Rio de Janeiro. As capturas (isca humana, paredes e armadilha luminosa) foram efetuadas, simultaneamente, em tres sitios de coleta: domicilio, peridomicilio e floresta. Foram capturados 10.172 flebotomineos, de 17 especies, sendo 3 do genero Brumptomyia e 14 do genero Lutzomyia. A especie mais prevalente a 100m do nivel do mar e L. intermedia, seguida de longe por L. migonei e L. fischeri. A especie mais endofila e que apresenta um certo ecletismo quanto ao local de hematofagia e L. fischeri, enquanto L. intermedia e L. migonei provaram ser mais exofilicas. L. intermedia pode ser incriminada como o principal vetor potencial do agente de leishmaniose tegumentar, pela sua prevalencia, antropofilia e por ser comprovada a veiculacao da Leishmania (Viannia) braziliensis em outras areas do Estado do Rio de Janeiro. L. fischeri, pela avidez com que pica o homem, pode ser um coadjuvante na transmissao do parasita. Sua predominância na floresta sugere participacao da transmissao em seu ciclo enzootico natural. A presenca de L. longipalpis e um risco potencial de veiculacao do agente etiologico da leishmaniose visceral nessa regiao, particularmente pela baixa imunidade da populacao local.

Ecologia dos flebotomíneos da Serra do Mar, Itaguaí, Estado do Rio de Janeiro, Brasil. I - A fauna flebotomínica e prevalência pelo local e tipo de captura (Diptera, Psychodidae, Phlebotominae)

A two-year investigation was conducted in Itaguai, State of Rio de Janeiro, an area with cases of cutaneous leishmaniasis, in order to study the ecology of sandflies and their habits and role as parasitic vector for men and animals. Capturing took place at three sites: domiciliary (human bait, walls, and light traps); peridomiciliary (walls, from baits used simultaneously: hu- mans, dogs, and chickens; and light traps); and sylvatic (human bait and light traps). A total of 10,172 sandflies were captured, belonging to 17 species of genuses Brumptomyia Franca & Par- rot, 1921 and Lutzomyia Franca, 1924. L. intermedia was predominant, 100 m above sea level, as compared to L. migonei and L. fischeri. In a drier area 300 m above sea level L. migonei was prevalent, followed by L. longipalpis and L. fischeri. The species which presented the greatest en- dophily was L. fischeri, showing a certain degree of eclecticism regarding the biting site. L. inter- media and L. migonei proved to be more exophilic. L. intermedia was considered to be poten- tially the main transmitter of the disease because of its prevalence, anthropophily, and the fact it is known to be a vector of Leishmania ( V.) braziliensis in other areas of the Southeastern region of Brazil. L. fischeri, because of its anthropophily, might also be involved.

Cutaneous leishmaniasis (CL) in the state of Rio de Janeiro is sporadic and can be characterised as a peridomestic transmission that occurs in modified natural environments. The aim of this work was to study the fauna and ecological characteristics of sandflies in an environmentally protected area (the State Park of Serra da Tiririca) within the remnants of the Atlantic Forest in the municipalities of Niteroi and Marica and their possible relationship with leishmaniasis. Captures were performed using light traps during the night once a month for one year in both sylvatic environments and areas surrounding homes near the park. A total of 1,037 sandflies were captured, belonging to nine genera and 12 species: Evandromyia tupynambai (34.1%), Migonemyia migonei (20.6%), Brumptomyia cunhai (13.8%), Micropygomyia schreiberi (9.7%), Psathyromyia lanei (6.5%), Brumptomyia nitzulescui (5.7%), Evandromyia edwardsi (5.4%), Nyssomyia intermedia (2.8%), Evandromyia cortelezzii (0.6%), Pintomyia bianchigalatiae (0.5%), Lutzomyia longipalpis (0.2%) and Sciopemyia microps (0.1%). Both Mg. migonei and Ny. intermedia may be acting as vectors of CL in this area.

The municipality of Cantagalo is an area with sustained transmission of American Cutaneous Leishmaniasis (ACL). Monthly sand fly collections were performed for three years (June 2012 - May 2015) using a CDC light trap. A total of 3,310 specimens belonging to 12 species were trapped: Nyssomyia intermedia, Nyssomyia whitmani, Migonemyia migonei, Evandromyia lenti, Evandromyia cortelezzii, Micropygomyia quinquefer, Brumptomyia brumpti, Psathyromyia aragaoi, Micropygomyia schreiberi, Pintomyia fischeri, Sciopemyia sordellii, and Evandromyia edwardsi. The last seven species have not been previously recorded in this area. The highest abundance of species occurred between October and March. October was the month with the highest number of captured sand flies, one month before the peak in the summer rainfall. In October the highest number of Ny. intermedia, Ny. whitmani and Mg. migonei, were also collected, the three epidemiologically most important species. The high abundance of species with epidemiological importance for ACL transmission might explain the sporadic occurrence of the disease in the area.
