Captura e identificação de culicídeos na cidade de Maceió, Alagoas

Abstract

Arthropods have vast biodiversity that represents their biological success. The characterization of the Culicinae subfamily is given by the presence of hairs and scales that give characteristic patterns used for the identification of these animals, considered, of great epidemiological importance due to the role they play as vectors of a range of pathologies such as viruses and parasitosis, especially in humans, and given the lack of recent studies in this location, this study aimed to identify and quantify the genera of mosquitoes (Diptera: Culicidae) in the urban area of the city of Maceió, Alagoas, for this, collections were carried out in the homes of volunteers randomly chosen in the districts of Ipioca and Cruz das Almas as with the use of CDC light traps, and in the district of Antares with Castro's manual catcher, later the quantification of individuals and the fixation and identification of females was carried out, following the Keys for identification of Culicidae described by Forattini (2002). The collections were carried out from November 2019 to July 2020, and 902 individuals were captured, of which 514 females and 381 males, and nine distinct genera Culex sp., Aedes sp., Haemagogus sp., Phoniomyia sp., Mansonia sp., Psorophora sp., Uranotaenia sp., Wyeomyia sp. and Limatus sp., the most abundant being Culex sp. followed by Aedes sp. with frequencies of 40% and 30% respectively. A variation in the distribution of genera was observed over the eight months of the study and between the districts where the collections were placed and between the collection methods, with a decrease in species diversity in the captures carried out using the Castro's manual catcher, however, further studies are needed to determine the correlation of this variation, with abiotic factors such as precipitation, and knowledge about possible differences in the distribution of Culicidae genera in other districts of Maceió.
