“…Similarly, a study conducted in the Private Natural Heritage Reserve of the Guapiaçu Ecological Reserve (REGUA) in the State of Rio de Janeiro recorded the highest numbers of mosquitoes in April and December (fall and summer, respectively), and the lowest numbers in June and October (winter and spring, respectively) [24]. However, this coincidence is not the case for other biomes, as reported by Freire et al ( 2021) in a study on a fragment of seasonal dry tropical forest (Caatinga biome) of the Conservation Unit Floresta Nacional de Açu [25]. Freire et al reported that the total number of mosquitoes collected varied widely, with September 2011 and July and May 2013 having a significantly higher abundance of culicids than in other months.…”

The yellow fever (YF) virus has been detected throughout Brazil, with the occurrence of human cases, cyclic epizootics, and its isolation from Haemagogus janthinomys and Hg. leucocelaenus. We assessed the seasonal occurrence, egg abundancy, and oviposition interaction of mosquito vector species captured at a Private Natural Heritage Reserve in the Atlantic Forest biome. A total of 2943 eggs and 1538 mosquito larvae were collected from which 1231 belonged to entomologically important species. Ovitraps were used to collect immature mosquitoes from September 2019 to January 2021. The Mann–Whitney test was used to assess the differences in the abundance of eggs between rainy and dry seasons. Kruskal–Wallis and Dunn’s post hoc tests were used to evaluate the significance of the differences in the number of individuals from vector species. The highest percentage of mosquito vector eggs were collected during the rainy season, from December to February. Most eggs recovered from ovitraps belonged to the species Hg. leucocelaenus, representing 85% of all mosquito eggs identified. The other species had lower abundances and percentages: Aedes terrens (7%), Haemagogus janthinomys (5%) and Aedes albopictus (3%). The species that shared breeding sites with a higher frequency were Hg. leucocelaenus and Hg. janthinomys, with a statistically positive correlation (ρ = 0.74). This finding suggests that maybe the presence of Hg. leucocelaenus eggs acted as an attractant for Hg. janthinomys or vice versa. An understanding of mosquito oviposition behavior is necessary for the development of surveillance and control approaches directed against specific pathogen vectors of medical and veterinary importance.

“…In ecosystems with high rainfall seasonality, as in our case, the rainy season presents favourable environmental and climatic conditions for the proliferation of mosquitoes, such as high relative humidity, higher average temperature and availability of breeding sites, which consequently lead to a greater diversity of mosquitoes in this period compared with the dry season (Afolabi & Aladesanmi, 2018;Freire et al, 2021;Steiger, Ritchie, & Laurance, 2016). Here, we demonstrated the temporal variations in a mosquito community along a rainy season, with the mosquito assemblage showing a peak in the number of species ( 0 D) and abundance in the month following the months with greater precipitation, which coincided with the middle of the rainy season.…”

“…For instance, Reiskind et al (2017) although found an overall decrease in species richness of mosquitoes from forest interior to pasture, show four common species significantly associated with this habitat. In addition, previous studies reported that some mosquito species, such as A. scapularis, often appear in high abundance and show a preference for open and modified areas in the Brazilian semiarid region (Ferreira et al, 2016;Freire et al, 2021;. When available, some mosquito species can take advantage of the conditions of artificial water containers in pasture areas, such as lower decaying matter, higher sunlight incidence, water temperature and algal proliferation to increase their populations (Tuno et al, 2005).…”

“…Regarding temporal variations, mosquito communities strongly respond to rainfall, exhibiting synchronized or highest activity when there is an increase in precipitation (Arcos et al, 2021; Freire et al, 2021; Steiger, Ritchie, & Laurance, 2016). Even in environments with limited seasonality such as the Amazon rainforest, mosquito species diversity is greater in periods of higher precipitation (Arcos et al, 2021).…”

“…Even in environments with limited seasonality such as the Amazon rainforest, mosquito species diversity is greater in periods of higher precipitation (Arcos et al, 2021). This seasonal pattern becomes more evident when mosquito diversity is compared between the dry and wet seasons of highly seasonal environments (Afolabi & Aladesanmi, 2018; Freire et al, 2021; Santos et al, 2015). The greater diversity of mosquito species in the rainy season has been mainly associated with the creation and/or increased availability of breeding sites for larval development (Arcos et al, 2021; La Corte et al, 2019).…”

Mosquito (Diptera: Culicidae) diversity along a rainy season and edge effects in a riparian forest in Southeastern Brazil

et al. 2022

Knowledge on the distribution of mosquito communities over time and across human‐modified landscapes is important in determining the risk for vector‐borne disease. The diversity of mosquitoes along a rainy season and edge effects were evaluated in a riparian forest in the Cerrado biome, Southeastern Brazil. Mosquito communities were sampled with Shannon traps in three distinct habitats (forest interior, forest edge and pasture) throughout an entire rainy season, comprising five sampling months (December 2015 to April 2016). A total of 13 549 mosquitoes belonging to 54 species were sampled. Mosquito species richness and abundance were greater in February, which coincided with the middle of the rainy season and just after the months with greater rainfall. Mosquito species richness did not differ among habitats for any particular month. In February, month when 74% of individuals were recorded, mosquito abundance was lower in the pasture compared with the forest edge and interior, which did not differ statistically from each other. Four of the six most abundant mosquito species (which account for 93.5% of the sampled individuals) had more individuals collected in the forest edge, and 28 species were more abundant at the edge compared with 15 species in the forest interior. Months with high rainfall probably allowed the availability and maintenance of high‐water level in breeding sites leading to a further increase in mosquito populations. While the pasture did not seem to have the ideal abiotic conditions and/or resources (e.g. food and breeding sites) for mosquito species, edge effects appear to favour mosquito populations. Therefore, the risk of mosquito‐borne diseases is expected to be greater in the middle of the rain season at the riparian forest‐pasture edge, when and where a greater number of disease‐vectoring species are present.
