Abstract
ABSTRACTThis is the description of how nine Aedes aegypti larvae were found in a natural breeding site in the Pinheiros neighborhood, city of Sao Paulo, SP, Southeastern Brazil. The record was conducted in December 2014, during an entomological surveillance program of dengue virus vectors, with an active search of potential breeding sites, either artificial or natural. Finding Ae. aegypti larvae in a tree hole shows this species’ ability to use both artificial and natural environments as breeding sites and habitats, which points towards the importance of maintaining continuous surveillance on this mosquito in all kinds of water-holding containers.
Highlights
Aedes (Stegomyia) aegypti (Linnaeus, 1762) is considered a mosquito of great importance to public health care since the early 20th century, when it was found to be a vector of urban yellow fever
This study aimed to report the finding of Ae. aegypti larvae in a natural breeding site in an urban area of the city of Sao Paulo, during entomological surveillance procedures
In Brazil, field studies with Ae. aegypti show that this mosquito is more frequently captured inside houses, and female mosquitoes are found to be engorged with human blood
Summary
Aedes (Stegomyia) aegypti (Linnaeus, 1762) is considered a mosquito of great importance to public health care since the early 20th century, when it was found to be a vector of urban yellow fever. Ae. aegypti is considered the main vector of the four dengue virus serotypes circulating in Brazil (DENV-1, DENV-2 DENV-3, and DENV-4), besides being a competent enough vector to transmit the arboviruses chikungunya and Zika, which have just arrived in the country[5]. The behavior of this vector is highly endophilic and anthropophilic; it seeks shelter inside houses, where it feeds from human blood. Albeit rarely, some studies report the finding of Ae. aegypti larvae in bromeliad plants in urban areas[2,4]
