Finding Aedes aegypti in a natural breeding site in an urban zone, Sao Paulo, Southeastern Brazil

Abstract

This 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.

Parity and gonotrophic discordance of females of Aedes aegypti and Aedes albopictus (Diptera: Culicidae) in the city of São Paulo, SP, Brazil

“…In fact, in area 2, where a larger number of Ae. aegypti was captured, the presence of this species has already been recorded in natural and artificial larval habitats (Lima‐Camara et al , Bermudi et al ).…”

“…aegypti was predominant in area 2, which is more developed and has a considerable movement of people. For both species, the number of males captured was greater than that of females in both collection areas, and this could be associated with the proximity of larval habitats, as the dispersal of the males seems to be more limited (Valerio et al , Lima‐Camara et al ). Beyond that, we found 40% and 39% of nulliparous females of Ae.…”

“…Further, the presence in area 2 of Ae. aegypti in both natural and artificial breeding sites was reported (Lima‐Camara et al , Bermudi et al ). The area was also very close to two cemeteries that might act as important larval sites for both Ae.…”

“…Five studies examined mosquito species composition at the neighbourhood level [112–116]. Three were conducted in Brazil [113–115], one in Haiti [112] and one in Argentina [116]. Both large-scale studies conducted in Brazilian parks in Sao Paulo found Ae.…”

“…Another study conducted in Brazil led to the collection of a small number of mosquito larvae in artificial and natural breeding sites, all of which were identified as Ae. aegypti [115]. The study conducted in Haiti found that an earthquake made conditions more suitable to Ae.…”
