SylvanYellow Fever Vectors: Updating the distribution of these mosquito species(Diptera:Culicidae) in Argentina María Eugenia CanoI;Evangelina MuttisI; Agustín BalsalobreI; Ailen ChuchuyI;Melisa B BonicaI; Soledad CeccarelliI; Gerardo A MartiI;María V MicieliII Centro de Estudios Parasitológicos yde Vectores (CEPAVE-CCT-La Plata-CONICET- UNLP), La Plata, Buenos Aires, 1900,Argentina. Yellow fever (YF) is an endemic disease in tropicalareas of Africa and South America whose etiologic agent is the yellow fevervirus (YFV) (Flaviviridae). This disease presents a sylvan cycle involvingnonhuman primates (NHP) and diurnal mosquitoes (Haemagogus sp. and Sabethessp.) that breed in these areas where humans might be incidentally infected andan urban cycle where the virus circulates among Aedes aegypti mosquitoes and humans. There is no intermediate cycleknown so far in South America, and it is presumed that the dispersion to urbanareas would be due to sporadic bites to humans in the sylvan areas where wildmosquitoes feed on monkeys Alouattaand Cebus genera, which are the mainhost/reservoirs of YFV. In Argentina, between 2007 and 2008, epizootics werereported in howler monkeys, causing high mortality in natural populations. Thisreemergence of YF represents a risk for human populations, and it is necessaryto conduct studies on distribution geographic patterns of sylvan mosquitospecies that are involved in these epizootics. These species have been poorlyreported in the last years (mainly in Yungas and Paranaense phytogeographicprovinces), although their historical distribution covers all of NorthernArgentina. In this study, we developed a database which gathers all theinformation available in literature and biological collections. Following theformat of DarwinCore, the database includes 76 fields grouped in categories:systematic, administrative divisions, geographical coordinates, specimencollection date, name/s of specimen collector/s, sampled habitat, samplingprotocol, total number of individuals sampled, references of the record.Recently, 35 scientific publications were reviewed and the database consists of445 records. Once these were obtained, distribution maps were made throughQGIS. The resulting maps of the genera Haemagogussp. and Sabethes sp. showed thatdespite having reviewed 35 from approximately 100 papers (35%), it is alreadypossible to confirm the original areas in addition to finding records indifferent areas such as the Chaco phytogeographic province. Furthermore, fieldstudies to be carried out in the coming years, will be conducted to update thisspecies distribution patterns and corroborate their historical distribution
