Abstract

Crop productivity most often varies across a field, with areas of relatively high and low crop yields. These landscape patterns for crop productivity may be associated with landscape patterns for differing levels of weed, disease, or insect pest pressure. An understanding of the landscape patterns for pests will be an integral component of effective and efficient pest management strategies designed to maintain high levels of crop production across all areas of a field. A path to such an understanding will require basic knowledge of where pests occur and processes controlling these landscape patterns.
