Figure 2. Effect of spatial scales on the Pearson correlation between the proportion of cropland and the abundance of cereal aphids and their natural enemy in agricultural landscapes (cereal aphids (individuals/100 straws): solid circular indicates S. avenae, hollow circular indicates S. graminum; primary parasitoids (individuals/100 straws): solid triangle indicates A. avenae, hollow triangle indicates A. gifuensis; leaf-ground predators (individuals/100 nets): solid square indicates H. variegata, hollow square indictes S. nitens; ground-dwelling predators (individuals/traps): solid rhomb indicates P. astrigena, hollow rhomb indicates C. spallipes).
