摘要: The reintroduction of sylvatic yellow fever in the state Sao Paulo after about six decades was confirmed Northwestern region 2000, where 2008 there also occurred an important epizootic. purpose this study to investigate feeding habits culicids potentially involved transmission virus region. Specimens were collected 24 forested localities at ground level with hand nets and mouth aspirators. Collections made quarterly between October 2006 July during daylight hours. Blood-meal identification carried out mosquitoes tribes Aedini, Mansoniini Sabethini. biotin/avidin sandwich ELISA employed determine source types: bird, bovine, equine, rat, human monkey. A total 24,879 females three obtained, 245 (0.98%) which engorged. presence different blood sources per engorged female predominant situation, included 35.10% samples processed. Samples two or four represented by 25.31% 25.71%, specimens, respectively, while just 9.39% had only one type 1.22%, five sources. Aedes scapularis, Ae. serratus (Group), Psorophora albigenu Ps. ferox most abundant species accounted for 95% specimens. Of principal vector species, Haemagogus janthinomys/capricornii found bovine primate blood. These alternated top ranking as frequent according mosquito collection site.
