Previous issue date: 2017-02-13 / Conselho Nacional de Desenvolvimento Cient?fico e Tecnol?gico (CNPq) / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (CAPES) / As leishmanioses s?o graves problemas de sa?de p?blica no Brasil, causadas por protozo?rios do g?nero Leishmania transmitidos pelos flebotom?neos, pequenos insetos da ordem Diptera cujas f?meas s?o hemat?fagas. A leishmaniose visceral (LV) ou calazar, tem como principal vetor nas Am?ricas Lutzomyia longipalpis e Leishmania infantum como agente etiol?gico. No Brasil, a Regi?o Nordeste se destaca com a maior incid?ncia de casos de LV, principalmente entre as camadas mais desfavorecidas da sociedade. A leishmaniose tegumentar (LT) possui diferentes vetores e agentes etiol?gicos em todo o pa?s, tem ampla distribui??o, e apesar da menor gravidade, causa s?rias les?es desfigurantes e incapacitantes em todas as regi?es, principalmente na regi?o Norte. ? relevante a introdu??o de estrat?gias de preven??o que venham a modificar as a??es humanas por meio da informa??o e sensibiliza??o para o problema, sendo a literatura de cordel um instrumento educativo que atrai por sua conota??o l?dica e informal, despertando a aten??o das pessoas. O presente estudo buscou, portanto, conhecer os flebotom?neos de uma Unidade de Conserva??o da Mata Atl?ntica e seu entorno, bem como alguns fatores bi?ticos e abi?ticos relacionados ? sua ocorr?ncia, al?m de testar a utiliza??o do cordel como ferramenta informativa sobre o tema. O estudo aconteceu durante tr?s anos na ?rea interna e externa da Floresta Nacional (Flona) de N?sia Floresta, localizada no munic?pio de N?sia Floresta, regi?o metropolitana de Natal, Rio Grande do Norte, utilizando-se armadilhas Shannon e CDC. Foi produzido um cordel, em seu formato cl?ssico, intitulado ?Um bebedor de sangue na terra do mandacaru - Peleja contra o calazar?, para a??es de educa??o em sa?de com a popula??o residente no entorno da Flona e com alunos de escolas do munic?pio. Foram coletados e identificados 82.638 flebotom?neos das esp?cies Evandromyia evandroi, Evandromyia lenti, Evandromyia walkeri, Evandromyia sallesi, Lutzomyia longipalpis, Micropygomyia schreiberi, Nyssomyia intermedia, Nyssomyia whitmani, Psathyromyia abonnenci, Psathyromyia brasiliensis, Psathyromyia shannoni, Psychodopygus wellcomei e Sciopemyia sordellii. Os flebotom?neos foram mais abundantes junto ao solo do ambiente silvestre, apesar de tamb?m serem abundantes junto ?s copas e no peridomic?lio rural. Evandromyia walkeri foi a esp?cie mais abundante, representando 76% de todos os flebotom?neos coletados, sendo importante outras investiga??es acerca dessa esp?cie. Lutzomyia longipalpis, E. evandroi e E. lenti demonstraram prefer?ncia pelos ambientes antropizados. Esse estudo comprova a elevada antropofilia de P. wellcomei, que se mostra ativo durante quase todo o dia no ambiente silvestre, bem como sua rela??o com os meses chuvosos. Com base no conhecimento da bioecologia dos flebotom?neos vetores das leishmanioses na ?rea, espera-se que esse trabalho possa contribuir com estrat?gias de preven??o e controle das leishmanioses no Nordeste.O cordel teve grande aceita??o por parte dos estudantes da EJA e a experi?ncia demonstrou que esse pode ser um importante meio para a dissemina??o de informa??es acerca da leishmaniose visceral, regionalizando as estrat?gias, sensibilizando e divulgando um tema t?o importante em sa?de p?blica. / Leishmaniasis is a serious public health problem in Brazil, caused by protozoa of the genus Leishmania transmitted by sand flies, small insects of the order Diptera whose females are hematophagous. The main vector of visceral leishmaniasis (VL), or kala-azar, in the Americas is Lutzomyia longipalpis while Leishmania infantum is the etiological agent. In Brazil, the Northeastern Region stands out with the highest incidence of VL cases, especially among the most disadvantaged groups of society. Tegumentary leishmaniasis (TL) has different vectors and etiological agents throughout the country, a wide distribution, and despite its lower severity, it causes serious disfiguring and disabling lesions all over the country, especially in the North Region. It is relevant to introduce prevention strategies, through information and consciousness of the problem, in order to modify deleterious anthropic actions. Cordel folk literature has proved to be an educational instrument with potential use to address this issue, since it attracts by its playful and informal connotations and awakens the attention of people of different age groups. This study aimed, therefore, to know the sand flies fauna at an Atlantic Forest Conservation Unit and its surroundings, as well as some factors related to their occurrence, in addition to testing the use of cordel literature as an informative tool on the subject. The study took place over three years in the internal and external area of the N?sia Floresta National Forest (Flona) located in the city of N?sia Floresta, metropolitan region of Natal, Rio Grande do Norte, using Shannon and CDC traps. A cordel pamphlet in its classic format was produced, entitled "A blood drinker in the land of mandacaru - fight against kala-azar," for health educational activities among the population living in the vicinity of the Flona and students. The use of the cordel was validated through questionnaires applied to students of the Education of Young and Adults Program. The pamphlet approaches the transmission, symptoms, treatment and prophylaxis of the disease. There were collected and identified 82,638 sand flies of the species Evandromyia evandroi, Evandromyia lenti, Evandromyia walkeri, Evandromyia sallesi, Lutzomyia longipalpis, Micropygomyia schreiberi, Nyssomyia intermedia, Nyssomyia whitmani, Psathyromyia abonnenci, Psathyromyia brasiliensis, Psathyromyia shannoni, Psychodopygus wellcomei and Sciopemyia sordellii. Phlebotomines were more abundant near the soil of the wild environment, although they were also abundant near the canopy and in the rural peridomicille. L. walkeri was the most abundant species, representing 76% of all sandflies collected, and other investigations about this species are important. L. longipalpis, E. evandroi and E. lenti showed preference for anthropized environments. This study confirms the high anthropophilic behavior of P. wellcomei, which is active throughout the day in the wild, as well as its relationship with the rainy months. Based on the knowledge of the bioecology of sand flies vectors of leishmaniasis in the study area, as well as the factors involved in its occurrence, it is expected that this work may contribute to strategies for the prevention and control of leishmaniasis in Northeastern Brazil. The cordel literature was widely accepted by students and the experience has shown that this may be an important way for dissemination of information about visceral leishmaniasis. It is also desired that the regionalization of educational strategies through cordel literature can contribute to the dissemination of knowledge, sensitizing the community and disseminating such an important subject in public health. / 2019-05-04
