Abstract

Leishmaniosis mainly in its visceral form caused by Leishmania (Leishmania) chagasi has been considered in the last decades, the most important zoonosis related to public health in São Paulo state in reason of its fast dissemination and potential risk to the human and animal health. For the maintenance of its epidemiological cycle its necessary the existence of three mainly factors. The first one is the presence of an infection source represented in urban areas by the dog or others domestics animals. The second one is the presence of invertebrate vector usually a sand fly of the sort Lutzomia spp and the third one is the existence of a propitious environment to the vector multiplication with decomposing organic material, humidity and shadow. The control of this illness represents a huge challenger for the local vector control team especially in the environmental factor that's depends directly on the interest of the population. The city of Botucatu, located in the interior of the state of São Paulo, to the edges of the Highway Marechal Rondon, next the cities as Bauru and Lençóis Paulista, cities these with confirmed transmission of L. (L.) chagasi, come suffering a great epidemiological pressure in reason from its localization and the flow of animals and human beings between these places, however until the present moment, they have not confirmed the local transmission of the visceral form of the illness, being endemic area only for the cutaneous form of leishmaniosis. This condition can be explained due to the fact that the Lutzomia longipalpis, mainly vector of visceral form, was not found in Botucatu city till the present moment. With the purpose to collaborate with the surveillance actions to this vector, it has been proposed to study thirteen selected areas with the higher risk to the presence of L. longipalpis with capture and identification of species and some spatial reflections as well based on geoprocessing and spatial statistics techniques.
