As part of area-wide pest management programs, insect abundance is often sampled at many locations distributed across large areas. These counts are then interpolated to form density surfaces that are used to make management decisions. Unfortunately traditional approaches to the design of sampling plans are not applicable to such programs but we review here some alternative geostatistical approaches that can be applied to estimate sampling intensities that are necessary to achieve fixed levels of precision. These methods are illustrated using historical counts of gypsy moths, Lymantria dispar, from regional trapping grids.
