Current Developments in the Integrated Management of Pests and Arthropod-Borne Diseases Using Spatially Based Risk Assessment Methods

摘要

Precision targeting is a method of determining the total distribution of any parameter of interest, and directing interventions based on that distribution. Based on geostatistics, precision targeting analyzes the locations and values of observations to discern a pattern of spatial continuity of the observations, then uses this pattern to estimate distributions between sampled locations. The total distribution is then expressed as a contour map showing isolines of equal parameter density. Precision targeting has many advantages, but perhaps the greatest improvement it brings to the pest manager is the reduction in pesticides needed to control pests. Precision targeting's inherent pinpointing of pest infestations eliminates the need to treat the entire facility, thereby reducing the amount of pesticide used, the exposure, and expense associated with current methodologies. Precision targeting can make a key contribution to achieving DoD's mandate to reduce pesticide use by 50 per cent by 2000 while actually increasing the effectiveness of operations.
