【 摘 要 】

Cutaneous (LTA)and Visceral (LVA) American Leishmaniasis incidence is increasing in human andcanine hosts, especially LVA, which is expanding throughout the State of SãoPaulo. Knowledge of the distribution and ecology of different sand fly speciesis essential for leishmaniasis epidemiological surveillance. The communicationof new findings of vectors, mainly the main LVA vector Lutzomyia longipalpis,is mandatory for determination of these illnesses' transmission risk. In thisstudy, sand flies were trapped in domiciliary, peridomiciliary and bushed areas,in different localities in rural areas of the Ipeúna and Itirapina counties,between October 2001 and February 2004. CDC automatic light traps were usedfrom 18h to 8h, during 14 nights, resulting in 420 hours of captures. A totalof 177 specimens pertaining to twelve different species were sampled. The mostabundant species was Nyssomyia neivai, pointed out as the main LTA vectorin the State of São Paulo, which totaled 85.4% of the specimens trappedin Ipeúna. The finding of Lutzomyia longipalpis in a cave in Itirapinaindicates the risk of LVA establishment in the area and the need for new localstudies on its ecology, especially with regard to occupation of anthropic environments.
