TL;DR: Analysis of the largest pest-control database of its kind shows that surrounding noncrop habitat does not consistently improve pest management, meaning habitat conservation may bolster production in some systems and depress yields in others.

TL;DR: In landscapes with high edge density, 70% of pollinator and 44% of natural enemy species reached highest abundances and pollination and pest control improved 1.7- and 1.4-fold respectively, suggesting that enhancing edge density in European agroecosystems can promote functional biodiversity and yield-enhancing ecosystem services.

TL;DR: It is found that parasitoids and ground-dwelling predators acted in a complementary way to suppress pollen beetles in oilseed rape, suggesting that pest control by multiple enemies attacking a pest during different periods of its occurrence in the field improves biological control efficacy.

TL;DR: It is recommended that future management schemes should coordinate the spatial aggregation and annual dynamics of oilseed rape (OSR) cover in a landscape as a potential way to reduce pest impacts in intensively managed OSR fields.

TL;DR: A strong spillover of carabid beetles from adjacent crop fields after crop harvest is found, which may result in transiently increased predation pressure and resource competition in calcareous grasslands.
