A Floresta Nacional de N?sia Floresta (FLONA-NF), localizada na regi?o Metropolitana de Natal, ? um remanescente de Mata Atl?ntica submetida a hist?ricas etapas de antropiza??o. Os fragmentos encontram-se em lenta regenera??o da mata nativa, portanto apresenta uma heterogeneidade de habitats, o que permite o desenvolvimento de esp?cies de culic?deos com variados h?bitos hematof?gicos e comportamentais, tais fatores estimularam a realiza??o do presente estudo na unidade de conserva??o. Os estudos com culic?deos permitem tamb?m avaliar o grau de altera??o ambiental em algumas regi?es. Esses insetos participam das cadeias epidemiol?gicas de doen?as com distribui??o geogr?fica extensa e ocorr?ncia em grandes grupos populacionais, tornando necess?rio o conhecimento das caracter?sticas biol?gicas das esp?cies com a finalidade de se conhecer pontos vulner?veis que facilitem o controle dos insetos vetores. Com o objetivo de realizar o primeiro levantamento de culicideos na ?rea preservada de N?sia Floresta foram realizadas coletas mensais de mosquitos adultos e imaturos por meio de quatro procedimentos metodol?gicos, coletas com armadilha Shannon, aspirador de Nasci, em brom?lias e larvitrampas entre fevereiro de 2013 e fevereiro de 2014. Foram coletados e identificados morfologicamente por meio de chaves entomol?gicas de identifica??o espec?fica, 8.299 indiv?duos, com a seguinte distribui??o: 7.677 mosquitos adultos coletados na armadilha Shannon; 397 mosquitos capturados por meio de aspirador el?trico de Nasci; 93 e 132 mosquitos imaturos em larvitrampas e brom?lias respectivamente. Entre os culic?deos foram encontrados nove g?neros com 19 esp?cies e 3 g?neros sem identifica??o da esp?cie. O presente estudo mostra-se relevante por ser o primeiro estudo realizado no local, com registro de ocorr?ncia de esp?cies no Rio Grande do Norte; pelo acr?scimo de informa??es sobre a ecologia dos culicideos e por acrescentar conhecimento sobre t?xons com import?ncia m?dica em outras regi?es do pa?s. Al?m disso, sinaliza para a import?ncia da conserva??o do fragmento florestal de mata atl?ntica e an?lises acerca da urbaniza??o das ?reas do entorno da unidade de conserva??o considerando a aproxima??o potencial de hospedeiros invertebrados, vertebrados e consequentemente a veicula??o de pat?genos com impacto na sa?de p?blica. / Studies on culicid fauna were conducted in anthropized areas of urban, rural and forest environments in different regions of Brazil. The National Forest of Nisia Floresta (FLONANF), located in the metropolitan region of Natal, is an Atlantic Forest remnant submitted to historical stages of anthropization. The fragments are in a stage of slow regeneration of native forest, exhibiting, therefore, heterogeneity of habitats, which enables the development of culicid species with varied hematophagic and behavioral habits. These factors stimulated the present study at the conservation unit. Studies of culicids also allow assessing the degree of environmental change in a number of regions. These insects participate in the epidemiological chains of diseases with extensive geographic distribution and occurrence of large population groups, requiring knowledge of the biological characteristics of species in order to determine the vulnerable points that facilitate control of vector insects. With the aim of performing the first culicid survey in the preserved area of Nisia Floresta, monthly collections of adult and immature mosquitoes were conducted by means of four methodological procedures, using a Shannon trap and Nasci aspirator in bromelias and larvitraps between February 2013 and February 2014. A total of 8,299 individuals were collected and identified morphologically using identification keys. The following distribution was obtained: 7,677 adult mosquitoes collected in the Shannon trap; 397 mosquitoes captured by the Nasci aspirator; and 93 and 132 immature mosquitoes in larvitraps and bromelias respectively. Nine genera of culicids were found with 19 species and three genera without species identification. The present study is relevant for being the first conducted at the site, with the occurrence of species in Rio Grande do Norte state; for adding knowledge about both the ecology of culicids and taxa with medical importance in other parts of the country. Furthermore, it highlights the need for conservation of the Atlantic Forest fragment and analyses regarding urbanization of areas surrounding the conservation unit, considering the potential presence of vertebrate and invertebrate hosts and consequent spread of pathogens with an impact on public health.

O s?tio Areias, no qual foi realizado o presente trabalho, est? localizado no munic?pio de Currais Novos-RN, no Serid? potiguar. Em tal regi?o ? predominante a Caatinga Hiperxer?fila Serid?, conhecida por ser a vegeta??o mais seca do estado, e est? em processo de desertifica??o. Durante o per?odo chuvoso, a caatinga pode apresentar h?bitats prop?cios para a prolifera??o de mosquitos, pois ? poss?vel o ac?mulo de ?guapermitindo assim o desenvolvimento de mosquitos com h?bitos comportamentais e hematof?gicos diversos. Tais fatores aliados a escassez de conhecimento da entomofauna de culic?deos na caatinga instigaram a realiza??o deste estudo. Para realiza??o do estudo, foram realizadas coletas mensais de mosquitos adultos, ovos e larvas por meio de dois procedimentos o primeiro com a armadilha Shannon e o segundo com a ovitrampa durante os per?odos de mar?o-maio e agosto-outubro dos anos de 2014 e 2015, em tr?s intervalos de hor?rios (17h-18h, 18h-19h e 19h-20h). Foram coletados e identificados 2291 esp?cimes, apenas na armadilha Shannon, n?o sendo observado nenhum ovo ou larva nas ovitrampas instaladas. A classifica??o revelou 14 t?xons: Anopheles marajoara; Anopheles argyritarsis; Anopheles braziliensis; Anopheles deaneorum; Aedes lepidus; Aedes scapularis; Aedes taeniorhynchus; Culex coronator; Culex (Cux.) spp.; Haemagogus spegazzinii; Mansonia indubitans; Mansonia wilsoni; Psorophora ferox e Uranotaenia lowii. Al?m da ocorr?ncia de esp?cies para o Rio Grande do Norte s?o mostradas rela??es ecol?gicas dos mosquitos na Caatinga potiguar. Tal estudo registrou pela primeira vez no Estado a presen?a das esp?cies Culex (Cux.) coronator e Anopheles (Nys.) deaneorum. Vale ressaltar ainda, que, a presen?a de algumas esp?cies em ?reas rurais pode ter alguma import?ncia quando se considera insetos com capacidade vetorial em ?reas pr?ximas aos hospedeiros, o que pode gerar impacto na sa?de p?blica. / In Rio Grande do Norte the latest studies on mosquito fauna have been carried out in protected areas in both morphoclimatic domains present in the state, the Atlantic Forest and Caatinga, these studies are limited in their geographical scope. The farm Areias, where this work was done, is located in the city of Currais Novos, RN, in the region of Serid?. On this region is predominantly Caatinga Hyperxerophilic Serid?, known by being driest vegetation of the state, in the process of desertification. During the rainy season, the caatinga can show habitats conducive to the proliferation of mosquitoes because the water accumulation is possible, allowing the development of mosquitoes with behavioral habits and several hematophagous. These factors associate with lack of knowledge of the insect fauna of mosquitoes in the bush, prompted this study. For the study, monthly mosquito, eggs and larvae collections were made through two procedures: the first with Shannon trap and the second with the egg trap during the period from march to may and august to october the years 2014 and 2015 in three intervals of time (17h-18h, 18h-19h and 19h-20h). They were collected and identified 2291 specimens, only the Shannon trap, eggs or larvae were not observed in ovitraps installed. The classification revealed 14 taxa: Anopheles argyritarsis; Anopheles braziliensis; Anopheles deaneorum; Anopheles marajoara; Aedes lepidus; Aedes scapularis; Aedes taeniorhynchus; Culex coronator; Culex (Cux.) spp.; Haemagogus Spegazzinii; Mansonia indubitans; Mansonia wilsoni; Psorophora ferox and Uranotaenia lowii. In addition to the occurrence of species in the Rio Grande do Norte state ecological relationships of mosquitoes are shown in Caatinga. This study recorded the first time in the state the presence of species Culex (Cux.) coronator (Group) and Anopheles (Nys.) deaneorum (identification male genitaly). It is worth noting also that the presence of some species in rural areas may have some importance when considering insects with vectorial capacity in areas close to the host, which may have an impact on public health.
