The functional role of biodiversity in ecosystems: incorporating trophic complexity. (2007, background): “Plant diversity can also reduce infestation by specialist insect parasites, probably for similar reasons (Otway et al. 2005).”
Synthesis and future research directions linking tree diversity to growth, survival, and damage in a global network of tree diversity experiments (2018, result): “This finding matches the resource dilution hypothesis (Otway et al., 2005), which predicts that herbivore abundance can be diluted among many hosts at high host frequency, and may be explained by the aggregation of attacks on the fewer and more apparent pines in mixed stands (Bañuelos and Kollmann, ”
Biological Control of Insect Pests in Agroecosystems: Effects of Crop Management, Farming Systems, and Seminatural Habitats at the Landscape Scale: A Review (2010, result): “…of this hypothesis in many cases (Andow, 1991), several recent studies have invalidated this prediction (see Yamamura, 1999, for a review), providing support for a Resource Dilution Hypothesis (Otway et al., 2005; Rhainds and English-Loeb, 2003) associated with different patterns of responses.”
