| description | Culicid species, which include potential vectors of yellow fever, are diverse and abundant, with species commonly co-occurring in certain sites. Studying these species can provide important insights into their vector potential and, consequently, epizootic cycles of arboviruses carried about by these vectors. Here, we evaluated the vertical distribution and temporal segregation of mosquito oviposition with emphasis on arbovirus vectors in a fragment of the Atlantic Forest in Casimiro de Abreu, Rio de Janeiro, Brazil. Two sampling points were selected: Fazenda Três Montes and the Reserva Natural de Propriedade Privada Morro Grande. Collections were carried out at two sites using 10 ovitraps installed on the vegetation cover at different heights (0, 2, 4, 6, and 8 m above ground level) and monitored monthly from July 2018 to December 2020. The hypotheses of temporal and vertical stratification were tested through a PERMANOVA, and the relationship of each species with the vertical distribution was evaluated individually through a correlation analysis. We collected a total of 3075 eggs, including four species of medical importance: <i>Haemagogus leucocelaenus</i> (<i>n</i> = 1513), <i>Haemagogus janthinomys</i> (<i>n</i> = 16), <i>Aedes albopictus</i> (<i>n</i> = 1097), and <i>Aedes terrens</i> (<i>n</i> = 449). We found that <i>Hg. leucocelaenus</i> had a positive relationship with height, exhibiting behavior that appears to benefit from higher heights. The abundance of <i>Ae. terrens</i> seemed to follow <i>Hg. leucocelaenus</i>, although we did not find a relationship with height for the former species. On the other hand, <i>Ae. albopictus</i> exhibited a negative relationship with height, becoming absent or outnumbered at higher strata. Our study site has already presented evidence of recent transmission of the wild yellow fever virus, supporting the need to carefully monitor the emergence of febrile diseases among residents in the surrounding areas and the local population. |
