Goal within the TERRECO Assessments:
Abstract: Landscape context and management intensity are major determinants of biodiversity patterns in agricultural landscapes, particularly those associated with biological pest control. In Haean, South Korea, we investigated the influence of landscape and management on the diversity of insect natural enemies and on their performance for pest control at multiple spatial scales. Results show that enemy diversity is generally higher in complex landscapes and in organic fields, and that different enemy guilds react to the landscape at different scales. Herbivory rates show a positive relationship with the abundance of natural enemies; a further exclusion experiment aims to clarify the direction and nature of this relationship and associated multitrophic interactions. In a separate experiment, herbivory rates are shown to increase with increased fertilizer input, while the presence of enemy pressure led to 20-60% decreased damage in all four fertilizer treatments.
