Spatial and Temporal Dynamics of Arthropods in Arable Fields

摘要: Pest distribution in an arable field is rarely homogeneous. As for diseases and weeds many different abiotic biotic factors can induce non-homogeneous or even aggregated distributions. Moreover animal pests are able to respond actively themselves external such as small differences local habitat quality through their behaviour. The combined effects of variations plant physiological stage climate, arthropod behaviour population dynamics , (tri-)-trophic interactions often result spatial distributions the pest, which evolve over time due pest-plant interactions. large number potential makes it almost impossible foresee at scale. In situ studies on pest be used reveal (stable) patterns. Then tempted correlate these intra-field variation (plant, etc.) characteristics. Stable (and/or predictable) patterns will certainly not occur all pests. Some examples cited, mainly occurring perennial crops and/or highly mobile Knowledge sustainable then optimise monitoring management. However, practical implementation knowledge management seems still very limited because technical (equipment) reasons impacts working methods
