phlebotomines (diptera: psychodidae) in a hydroelectric system affected area from northern amazonian brazil: further insights into the effects of environmental changes on vector ecology.during 2012-2015, an entomological survey was conducted as part of a phlebotomine (diptera: psychodidae) monitoring program in an area influenced by the santo antônio do jari hydroelectric system (amapá state, brazil). the purpose was to study aspects of amazon/guianan american cutaneous leishmaniasis (acl) vectors subjected to stresses by anthropogenic environmental changes. for sampling, cdc light traps were positioned 0.5, 1, and 20 m above ground at five capture locations along the jari rive ...201628042300
[sandfly fauna (diptera: psychodidae) in a focus of american cutaneous leishmaniasis on the urban periphery of manaus, state of amazonas].from august 2001 to july 2002, sand flies were collected from the bases of trees and, using cdc and disney traps, from areas surrounding homes and forested areas in the são joão community, on the urban periphery of manaus, state of amazonas. 4,104 specimens belonging to four subtribes, 13 genera and 49 species of the phlebotominae subfamily were collected. the subtribe psychodopygina predominated, with 3,403 (83%) specimens, especially of nyssomyia umbratilis, nyssomyia anduzei, trichophoromyia ...200819009191
natural infection of phlebotomines (diptera: psychodidae) by leishmania (leishmania) amazonensis in an area of ecotourism in central-western brazil.bonito municipality, known as an area of ecoturism, in mato grosso do sul state, brazil, is also a focus of visceral and cutaneous leishmaniases, with cases registered in both human and canine populations. this study sought to investigate natural infection by flagellate forms of leishmania in phlebotomines of the urban area of bonito.201526435708
sandflies in an urban area of transmission of visceral leishmaniasis in midwest brazil.the phlebotomine fauna of campo grande city, capital of mato grosso do sul state in brazil, an endemic area for visceral leishmaniasis, has been thoroughly investigated, but all the insect collections were undertaken with automatic light traps. the present study sought to investigate the fauna in this city using shannon and disney traps, having human beings and hamsters, respectively, as bait. both types of traps were installed in forest fragment and peridomiciliary areas in the period from 2007 ...201627593433
