The number of invasive non-native pests is increasing rapidly in forests as a result global change. It therefore important to prevent their damage order preserve the integrity forest ecosystems and associated services. According biotic resistance hypothesis, species-rich communities are less likely be invaded. associational hypothesis states that insect herbivores more colonise exploit plants surrounded by conspecific neighbours than heterospecific, non-host plant species. More diverse would damaged tree monocultures. We tested this comparing caused seeds western conifer bug Leptoglossus occidentalis, an native North America, plots pure maritime pine mixed birch. These were two diversity experiments Europe. Mixed differed terms density (1,250 versus 625 pines/ha), proportion birch (25%, 50%, 75%) spatial mixing pattern (aggregated dispersed). Overall, was significantly lower at both experimental sites. There no significant effect or relative mixtures on seed damage. Aggregated pines dispersed pines, suggesting bugs did when they had difficulty locating host trees, which consistent with apparency. results confirm plantations species, known vulnerable attack insects, also resistant infestation exotic insects. Row-wise, intimate species represent promising option for designing easier manage.

How frequently, and under what conditions, biodiversity reduces disease through "dilution effects" has been a subject of ongoing research. A new study forest pests in PLOS Biology provides strong evidence for their generality.
