Technical Abstract: If the foundation of an effective pest management program is an understanding of pest ecology and behavior, then this understanding must be at an appropriate spatial and temporal scale for the pest species. This is because the structure of the landscape mosaic influences ecological processes such as population dynamics, movement patterns, and spatial distribution. Stored-product pests occupy spatially and temporally fragmented landscapes that can have profound impacts not only on their population dynamics, but also our ability to monitor populations and effectively target pest management. Recent research findings regarding these broader landscape issues in relation to stored-product pest spatial distribution and movement patterns will be presented. The focus will be on recent research findings on Rhyzopertha dominica, the lesser grain borer, temporal and spatial patterns in flight activity and dispersal, and the influence of land-cover and land-use patterns on flight activity. How this data has generated new hypotheses about the ecology and behavior of this pest and provided insight into more targeted pest management approaches will also be discussed.
