Pest control ~ Landscape complexity

Image: Fig 1 from Rusch et al. (2016)¬†Agric Ecosyst Environ. It’s well demonstrated that increased habitat complexity tends to increase arthropod biodiversity and, importantly, the abundance of natural enemies. Therefore, it is thought that increasing complexity in agricultural landscapes should increase the level of pest control too. But is this true? Does increased landscape complexity actually result in fewer pests? There have been a few great studies that have looked at this question (e.g. Gardiner‚Ķ
