| Popis: | Several mosquito species in the Atlantic Forest are yellow fever vectors; therefore, this biome can represent a potential risk to the human population. Studies on mosquitoes from predominantly sylvatic areas produce valuable data for understanding the emergence of new epidemics. In addition, they can elucidate environmental components favoring or hindering biodiversity and species distribution. Our study aimed to evaluate the monthly distribution, composition, diversity, and influence of seasonal periods (dry and rainy) on the mosquito fauna. We used CDC light traps at different levels in a forest area bordering a Conservation Unit of Nova Iguaçu in the state of Rio de Janeiro, Brazil. Specimens were collected from August 2018 to July 2019 by installing traps in sampling sites under different vegetation covers. We detected some species of epidemiological importance in terms of arbovirus transmission. A total of 4,048 specimens representing 20 different species were collected. Among them, Aedes (Stg.) albopictus Skuse, 1894 showed recurrent association with the closest level to human residences and Haemagogus (Con.) leucocelaenus Dyar and Shannon, 1924 with the most distant levels. Since these mosquitoes are possible vectors of yellow fever, monitoring the area is extremely important. Under the studied conditions, the mosquito populations were directly influenced by dry and rainy periods, posing a risk to the nearby resident population. |
