PhD Thesis: "The effects of surrounding landscapes on the biocontrol-production function in rice dominated agroecosystems"
In the Asian rice agroecosystems, the brown planthopper (Nilaparvata lugens) is a major threat to rice production, causing significant yield loss.
My research aims to test the potential influence of landscape complexity on the distribution of specific species representative for the given predator-prey system. I use a landscape ecology approach together with a simulation model to understand the basic dynamics of the predator-prey system and examine the effects of temporal land use regimes on the distribution of rice pests and pest-controlling species at a regional scale.
