Simple Summary Zoological gardens in forest areas host a large diversity of vertebrate species (exotic and indigenous, free-living and captive, migrant and resident), resulting in an artificial proximity of animal species that would never share the same environment in natural conditions. The presence of mosquitoes enables the transmission of vector-borne pathogens, as is the case with avian malaria parasites. The mild infections in some bird species may become a serious threat to others that do not possess a natural resistance. Thus, the identification of the potential vectors of these parasites is important for future control of these agents, aiming at the bird species conservation. In this study, we collected over 2000 mosquitoes in Sao Paulo Zoo and analyzed them through molecular methods. Six different mosquito species yielded positive for the targeted parasite DNA. We demonstrated that these culicids had fed mainly on bird species and we reported three mosquito species that have never been previously incriminated as potential vectors of these parasites, enabling the use of more specific measures for vigilance and mosquito control. Avian malaria parasites are widespread parasites transmitted by Culicidae insects belonging to different genera. Even though several studies have been conducted recently, there is still a lack of information about potential vectors of Plasmodium parasites, especially in Neotropical regions. Former studies with free-living and captive animals in Sao Paulo Zoo showed the presence of several Plasmodium and Haemoproteus species. In 2015, a pilot study was conducted at the zoo to collect mosquitoes in order to find out (i) which species of Culicidae are present in the study area, (ii) what are their blood meal sources, and (iii) to which Plasmodium species might they be potential vectors. Mosquitoes were morphologically and molecularly identified. Blood meal source and haemosporidian DNA were identified using molecular protocols. A total of 25 Culicidae species were identified, and 6 of them were positive for Plasmodium/Haemoproteus DNA. Ten mosquito species had their source of blood meal identified, which were mainly birds, including some species that were positive for haemosporidian parasites in the former study mentioned. This study allowed us to expand the list of potential vectors of avian malaria parasites and to improve our knowledge of the evolutionary and ecological relationships between the highly diverse communities of birds, parasites, and vectors present at Sao Paulo Zoo.
