Fig. 1 shows the edge of an agricultural field beside a small woodland in France. A farmer has planted a strip of native wildflowers between the crop and the wood. The diagram shows ladybirds, aphids on crop plants and a bird feeding in the strip. The farmer hopes to reduce pesticide use while maintaining yields. This study figure can be used to consider biological control in a managed landscape.
