Previous issue date: 2014-09-30 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (CAPES) / Em diversas regi?es do pa?s foram realizados estudos da fauna de culic?deos em ?reas
antropizadas de ambientes variados, urbanos, rurais e florestais. 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.
