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

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.

Ecological Aspects of Phlebotomine Sand Flies (Diptera, Psychodidae, Phlebotominae) in Areas of American Cutaneous Leishmaniasis, in the Municipality of Paraty, Rio de Janeiro, Brazil. I-Index of Abundance by Location and Type of Capture.

The description of the first and autochthonous case of diffuse cutaneous leishmaniasis in the municipality of Paraty, State of Rio de Janeiro, brought the interest of this study. Sand flies were captured over a 3-yr period. Using manual suction tubes, sand flies were collected from the inner and outer walls of homes, in the living spaces of domestic animals, and in Shannon light traps, which were set up outside homes and in the forest. CDC light traps were installed inside homes, around the exterior of the houses, and along the divide and within the forest. A total of 102,937 sand flies were collected, representing 23 species--three from the genus Brumptomyia and 20 from the genus Lutzomyia. Of these, six species, Lutzomyia intermedia, Lutzomyia fischeri, Lutzomyia migonei, Lutzomyia whitmani, and Lutzomyia pessoai have already been recorded as being naturally infected by Leishmania braziliensis, and one species, Lutzomyia ayrozai, by Leishmania naiffi. Lu. intermedia is the vector of Le. braziliensis in the study area, particularly inside the homes and on the exterior of the houses. Lu. fischeri can also act as vector of Le. braziliensis in domestic environments and particularly in the wild. The third-ranked Lu. migonei was the most abundant in kennels, suggesting its canine affinity. Lu. whitmani, ranked fourth, still has characteristics indicative of the wild, but with a significant number located on the edge of the forest, suggesting a selection process of adaptation to the anthropic environment.
