Observações sobre o comportamento de flebotomíneos em ecótopos florestais e extraflorestais, em área endêmica de leishmaniose tegumentar americana, no norte do Estado do Paraná, sul do Brasil

Abstract

10,17,23,24 . Além disso, há evidências de que os flebotomíneos vêm encontrando nesses locais, ou nas suas proximidades, condições apropriadas para a procriação, devido à elevada densidade de insetos machos, que têm menor capacidade de dispersão 28 . O caráter endêmico da leishmaniose tegumentar no Norte do Paraná requer investigações sobre o comportamento dos flebotomíneos, em decorrên-

Ecologia de Lutzomyia (Nyssomyia) whitmani em área urbana do município de Maringá, Paraná

“…Thus, seasonality similar to what has previously been observed in rural areas of northern Paraná for L. whitmani using the same trap type can be confirmed. 11,14,15 The results from the present work also show that, in the collections performed in the Shannon traps, the greatest number of specimens of L. whitmani (55.1%) was collected in one of the driest and coldest months of the year (August). This therefore differs from the seasonality observed previously, 12 which was also in the rural area of this region, and using the same trap type.…”

Sandflies (Diptera: Psychodidae) in rural and urban environments in an endemic area of cutaneous leishmaniasis in southern Brazil

“…In other studies, different results have been found for PR, where Ny. whitmani prevailed in the northwestern region (67.82%) (Teodoro et al 1991), in the northern region (76.3%, 70%) (Teodoro et al 1993a, Muniz et al 2006) and even in Bandeirantes (58.9%) (Massafera et al 2005). Ny.…”

“…in many studies) and Ny. whitmani are consistently present in high numbers in peridomestic and domestic areas in most parts of northern PR (Teodoro et al 1993a, b, Teodoro & Kuhl 1997, Oliveira et al 2000, Massafera et al 2005.…”

“…Studies of the sandfly fauna in PR have been undertaken more extensively in the northern region, where the greatest numbers of ACL cases have been registered (Gomes & Galati 1977, Teodoro et al 1991, 1993a, b, 2001, Teodoro & Kuhl 1997, Oliveira et al 2000, Massafera et al 2005. Nyssomyia neivai (Pinto, 1926), Nyssomyia whitmani (Antunes & Coutinho, 1939), Pintomyia pessoai (Coutinho & Barretto, 1940), Pintomyia fischeri (Pinto, 1926) and Migonemyia migonei (França, 1920) are the most commonly suspected vectors of Leishmania sp.…”

Diversity of sand flies in domiciliary environment of Santarém, state of Pará, Brazil: species composition and abundance patterns in rural and urban areas

“…However, cases of canine and human AVL in typical urban areas are now more frequent, suggesting a modification of the classic model of endemic area (Rêbelo et al 1999;Teodoro et al 1993). Higher disease prevalence in women and children and markedly domiciliary and peridomiciliary presence of vectors reveal a tendency of sand fly adaptation to man-made habitats, where they are responsible for transmission of Leishmania spp.…”
