Question 1 Report
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.
(a) Explain how the wildflower strip could help reduce aphid damage to the crop. [2]
(a) Wildflowers provide nectar/shelter for predators such as ladybirds [1]; more predators eat aphids, reducing aphid numbers and crop feeding damage [1].
