“…These parks, which are located in densely populated areas, have undergone major environmental changes as a result of human activities and urbanization. More than 1 million people visit Ibirapuera park every month, and Piqueri park is located next to a major highway, where more than 400 thousand vehicles circulate every day [7,12]. …”

“…The species is able to survive in wild, semi-wild, suburban and urban areas [10,11]. Indeed, it successfully inhabits urban environments and is found abundantly in the city of São Paulo, where it represented around 10% of all mosquito specimens collected in recent studies, indicating that it is well adapted and established in this urban environment [7,12]. Females of the species are highly anthropophilic and have been reported to ingest human blood while their eggs are developing [13].…”

Population Genetic Structure of Aedes fluviatilis (Diptera: Culicidae)

et al. 2016

Although Aedes fluviatilis is an anthropophilic mosquito found abundantly in urban environments, its biology, epidemiological potential and genetic characteristics are poorly understood. Climate change and urbanization processes that result in environmental modifications benefit certain anthropophilic mosquito species such as Ae. fluviatilis, greatly increasing their abundance in urban areas. To gain a better understanding of whether urbanization processes modulate the genetic structure of this species in the city of São Paulo, we used eight microsatellite loci to genetically characterize Ae. fluviatilis populations collected in nine urban parks in the city of São Paulo. Our results show that there is high gene flow among the populations of this species, heterozygosity deficiency and low genetic structure and that the species may have undergone a recent population expansion. There are two main hypotheses to explain these findings: (i) Ae. fluviatilis populations have undergone a population expansion as a result of urbanization; and (ii) as urbanization of the city of São Paulo occurred recently and was quite intense, the structuring of these populations cannot be observed yet, apart from in the populations of Ibirapuera and Piqueri parks, where the first signs of structuring have appeared. We believe that the expansion found in Ae. fluviatilis populations is probably correlated with the unplanned urbanization of the city of São Paulo, which transformed green areas into urbanized areas, as well as the increasing population density in the city.

“…The more urbanized an area is, the lower the mosquito richness and the higher the abundance of a few, epidemiologically important mosquito species that are well adapted to urban environments [1–3]. Mosquitoes of the Aedes , Culex and Anopheles genera are responsible for the transmission of highly important infectious diseases such as dengue, filariasis, West Nile virus disease and malaria.…”

Morphometric Wing Characters as a Tool for Mosquito Identification

et al. 2016

Mosquitoes are responsible for the transmission of important infectious diseases, causing millions of deaths every year and endangering approximately 3 billion people around the world. As such, precise identification of mosquito species is crucial for an understanding of epidemiological patterns of disease transmission. Currently, the most common method of mosquito identification relies on morphological taxonomic keys, which do not always distinguish cryptic species. However, wing geometric morphometrics is a promising tool for the identification of vector mosquitoes, sibling and cryptic species included. This study therefore sought to accurately identify mosquito species from the three most epidemiologically important mosquito genera using wing morphometrics. Twelve mosquito species from three epidemiologically important genera (Aedes, Anopheles and Culex) were collected and identified by taxonomic keys. Next, the right wing of each adult female mosquito was removed and photographed, and the coordinates of eighteen digitized landmarks at the intersections of wing veins were collected. The allometric influence was assessed, and canonical variate analysis and thin-plate splines were used for species identification. Cross-validated reclassification tests were performed for each individual, and a Neighbor Joining tree was constructed to illustrate species segregation patterns. The analyses were carried out and the graphs plotted with TpsUtil 1.29, TpsRelw 1.39, MorphoJ 1.02 and Past 2.17c. Canonical variate analysis for Aedes, Anopheles and Culex genera showed three clear clusters in morphospace, correctly distinguishing the three mosquito genera, and pairwise cross-validated reclassification resulted in at least 99% accuracy; subgenera were also identified correctly with a mean accuracy of 96%, and in 88 of the 132 possible comparisons, species were identified with 100% accuracy after the data was subjected to reclassification. Our results showed that Aedes, Culex and Anopheles were correctly distinguished by wing shape. For the lower hierarchical levels (subgenera and species), wing geometric morphometrics was also efficient, resulting in high reclassification scores.

Os Flavivirus são transmitidos por mosquitos (Diptera: Culicidae) que se refugiam em remanesctentes de Mata Atlântica. Essas áreas verdes correspondem às Unidades de Conservação e parques urbanos, que estão espalhados pela região metropolitana de São Paulo. Este estudo foi realizado com o intuito de conhecer as espécies de culicídeos que circulam na Área de Proteção Ambiental (APA) Capivari-Monos, na zona Sul do município de São Paulo, e no Parque Estadual da Cantareira (PEC), na zona Norte do mesmo município, e de investigar infecção natural por Flavivirus na fauna de culicídeos amostrada. Também foi proposto relacionar a variedade, a quantidade e identidade dos Flavivirus detectados com os padrões de riqueza, abundância e diversidade das assembleias de mosquitos. Foram realizadas 14 coletas, mensalmente, em quatro pontos de coleta na APA e três no PEC, todos com diferentes níveis de intervenção antrópica, no período de março de 2016 a abril de 2017. Armadilhas automáticas luminosastipo CDC (com atração de CO2 e ácido lático) foram instaladas na copa das árvores e no nível do solo. O esforço amostral foi equivalente para os todos os pontos, sendo que foram instaladas duas armadilhas em cada ponto (uma na copa e outra no solo), com 18 horas de coleta, permitindo amostragem de culicídeos de hábitos diurnos, crepusculares e noturnos. Os espécimes foram transportados com vida para o
