Pest-suppressive landscapes from a natural enemy perspective

Analysis of sentinel data acquired in many different landscapes showed significant relationships between the green-veining of the landscape (non-crop areas) and the level of biocontrol observed in the crops. For instance, the presence of forest within 500 m appears to be associated with a high rate of parasitism of diamondback moth larvae in cabbage fields. Applying a new analysis method, a kernel approach, we are able to derive maps showing the intensity and spatial extent of biocontrol services provided by the landscape.
