Ecology Letters (2011) 14: 922–932 Abstract Many studies in recent years have investigated
the relationship between landscape complexity and pests, natural enemies and/or pest …

Agricultural intensification has resulted in a simplification of agricultural landscapes by the
expansion of agricultural land, enlargement of field size and removal of non-crop habitat …

Numerous studies show that landscape simplification reduces abundance and diversity of
natural enemies in agroecosystems, but its effect on natural pest control remains poorly …

Landscape management could contribute to sustainable pest control. Landscape
composition, in particular, could either directly impact a pest abundance by affecting its …

Landscape structure influences local diversity and ecosystem processes, including cross-
habitat fluxes of organisms coupling the dynamics of different habitats. The flow of …

Numerous recent studies have tested the effects of plant, pollinator, and predator diversity
on primary productivity, pollination, and consumption, respectively. Many have shown a …

Agricultural land use threatens ecosystem services such as biological control by natural
enemies because of simplification of habitat structure and intensification of disturbance and …

Numerous studies have demonstrated that diverse predator assemblages can be more
effective at controlling prey populations. Yet, other studies have shown no effect of predator …

A growing body of literature points to a large-scale research approach as essential for
understanding population and community ecology. Many of our advances regarding the …

The loss of landscape heterogeneity through agricultural intensification is known to affect
aphid–parasitoid–hyperparasitoid interactions, with consequences for biological control …
