Abstract:Changes in land use is an important driver of insect pest population dynamics, but the long-term effects of land use may be contingent on changes in some factors. To identify potential effects of change in cropping pattern on agricultural pest population trends, data from large temporal and spatial scales are needed but are rarely available. Here, we use long-term pest monitoring data across a regional scale and across independent gradients of land-use intensity at the landscape level, to investigate the effec… Show more
