“…The subgenus Psychodopygus represented 59.5% of the total specimens captured and the subgenus Nyssomyia represented 23.7%. These two subgenera are indeed described as the most predominant in the Amazon Region and are more prevalent there than in any other region of the Americas (Ward et al 1973, Silva et al 2007). Species considered important vectors for cutaneous leishmaniasis, in both enzootic and zoonotic cycles, are classified into these two subgenera (Grimaldi et al 1991, Gil et al 2003.…”

“…Previous works published on the sand fly fauna collected in the state of Amazonas using various strategies reported three genera as the most abundant: Nyssomyia Barretto, 1962, Psychodopygus and Trichophoromyia (Barrett et al 1996;Castellón et al 2000;Dias-Lima et al 2002;Feitosa & Castellón 2006;Silva et al 2007;Guerra et al 2006). Two other common genera found by these studies were Psathyromyia (Barrett et al 1996) and Trichopygomyia (Silva et al 2007). Unlike these previous studies, our results showed the largest abundance of specimens in the genera Trichopygomyia, Psathyromyia, Psychodopygus and Trichophoromyia, respectively, and this fact is due to one or two highly abundant species in each of these genera (Ty.…”

ResumoOs flebotomíneos transmitem doenças a humanos e animais, como as arboviroses e bartonelose, além das leishmanioses. O objetivo desta pesquisa foi identificar possíveis espécies de flebotomíneos vetores da doença nessa região no município de Tabatinga. Flebotomíneos foram capturados com armadilhas luminosas e em coletas manuais por aspiração em bases das árvores. Nos meses de agosto dos anos 2010 e 2011, foram capturados 4.542 flebotomíneos (♂: 71,9% e ♀: 28,1%) vetores ou suspeitos de transmitirem tripanosomatídeos, pertencentes a 13 espécies. A espécie mais abundante foi Lutzomyia umbratilis com 78,7%. Um total de 576 (74,0%) flebotomíneos do gênero Lutzomyia foram dissecados, sendo observada infecção natural por tripanosomatídeos em 44 fêmeas. Observou-se no trato digestório dos flebotomíneos a presença de sangue em decomposição em 86,3%; sendo que no que se refere aos ovários, 59,0% mostravam-se em desenvolvimento. A análise isoenzimática de dez isolados, demonstrou perfis similares a Leishmania colombiensis e Endotrypanum sp., no entanto, o perfil do locus Malato Desidrogenase (MDH) demonstrou maior similaridade para o gênero Endotrypanum. Esta é a primeira investigação da fauna entomologia e tentativa de isolamento de tripanosomatídeos no município de Tabatinga, área de tríplice fronteira com o Brasil.Palavras-chave: Amazonas, Endotrypanum, flebotomíneos, Lutzomyia. Vectors of Trypanosomatids (Kinetoplastida: Trypanosomatidae) in Tabatinga,Amazonas, Brazil AbstractThe sand flies transmit diseases to humans and animals, such as arboviruses and bartonellosis, besides the leishmaniasis. The objective of this research was identified potential vectors of this disease in the municipality of Tabatinga. Sand flies were captured with miniature light trap and manual collection by aspiration at the bases of trees. In the months of august 2010 and 2011, were captured 4,542 sand flies (♂: 71.9% and ♀: 28.1%) vectors or suspected of trypanosomatids transmission, belonging to 13 species. The most abundant species was Lutzomyia umbratilis with 78,7%. A total of 576 (74.0%) sand flies of the genus Lutzomyia were dissected and natural infection by trypanosomatids was observed in 44 females. Blood in decomposition was detected at the digestive tract in 86,3% insects; being 59.0% of the ovaries in developing. The isoenzymatic analysis of ten isolates showed similar profiles to Leishmania colombiensis and Endotrypanum sp., however, the profile of the locus Malate Dehydrogenase (MDH) showed major similarity to the genus Endotrypanum. This is the first investigation of the fauna entomology and attempt of trypanosomatids isolation in the municipality of Tabatinga, area of triple border with Brazil.
