Technical Abstract: Mosquitoes transmit (vector) disease agents that cause malaria, yellow fever, dengue, West Nile fever, and encephalitis. Spread of these diseases is controlled by the management of mosquito population levels, changes in which are monitored in vector surveillance programs by the use of mechanical traps. Graphical depiction of mosquito surveillance data facilitates understanding of the spatial extent of mosquito distribution and disease transmission patterns. At this meeting of Geographic Information System (GIS) software users, ARS scientists demonstrated a graphical model of temporal change in mosquito surveillance data collected in northeastern Florida in 2005. The data were analyzed with the Geostatistical Analyst extension in ArcGIS v9.2 and the density contours generated using Inverse Distance Weighted Interpolation. Output comprised color contours for three different species of mosquitoes representing, in each case, the maximum monthly density of females per trap night. As a result of this process, multiple discrete locations of mosquito activity were identified and geo-referenced within the study area thereby providing a focus for the precision targeting and application of mosquito control measures.
