The cutaneous leishmaniasis (CL) is a chronic infectious disease with worldwide distribution, characterized by the manifestation of lesions in the skin. The etiologic agents are protozoa of the genus Leishmania. The epidemiology of CL has its own characteristics in each area, resulting in variables related to parasites, vectors and processes for use and occupation of soil. The aim of this study was to visualize, identify and determine the locations to capture and study of phlebotomine fauna in the municipality of Santarém / PA by using a GIS. The kernel was used to select study areas and thus realize a survey the sandfly fauna using CDC traps in intra (IH) and outside homes (OH) and Shannon traps in wild environment (WE). The kernel has identified the two major circuits spatial production of CL cases, Jatoba and Corta-Corda. The total of 222 sandflies of 15 species was captured in the two circuits. Jatoba had the largest number of specimens captured in IH/OH and the specimen Lutzomyia longipalpis was more abundant. In WE, the largest number was captured in Corta-Corda and Psychodopygus davisi predominated in this environment. The presence of B. flaviscutellata in IH/OH indicates greater exposure to the domestic Le. amazonensis. The presence of Lu. longipalpis in IH/OH suggests that these environments are providing adequate conditions for the establishment of this species. The kernel was a useful strategy to guide the surveillance and prevention of disease. The generated data supports decision making to define priority areas for interventions. (AU)
