The arboviruses transmitted by Culicidae of the genus Aedes, Dengue (DENV), Chikungunya (CHIKV) and Zika virus (ZIKV), have recently been considered a major public health challenge. New monitoring methodologies for the knowledge of vulnerable areas for the transmission of arboviruses have been used and the oviposition traps (OVITRAMPAS) have been sensitive to the knowledge of these areas, associated with favorable conditions. The use of georeferencing through the construction of maps is another tool that allows visualizing the distribution, concentration and incidence of health problems. Therefore, the present work had as objective to know areas vulnerable to presence through the use of oviposition traps and georeferencing in the municipality of Agrestina, PE. For egg collection, oviposition traps were used in 35 georeferenced points, distributed in seven neighborhoods, as a biweekly collection, from May 2016 to April 2017. The climatic data of temperature, humidity and rainfall were correlated as the (IPO), Egg Density Index (IDO) and Vector Density Index (IDV) for the classification of areas between control, alert and risk. After these steps Kernel themed maps were constructed for the knowledge of the areas of greatest vector infestation. A total of 44,936 eggs were collected. Throughout the study period, the rates of infestation showed variations between control, alert and risk zones. Regarding the climatic factors, rain was the factor that contributed significantly to the vector infestation and through the thematic maps the spatial distribution of the areas of higher transmission to the arboviruses was verified. The oviposition traps, associated with the analysis of climatic factors, as well as the use of entomological indexes and the application of georeferencing tools, indicate good strategies for the knowledge of control of areas vulnerable to arbovirus transmission.
