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 …

The role of generalist predators in biological control remains controversial as they may not
only reduce pest populations but also disrupt biocontrol exerted by other natural enemies …

Natural enemy biodiversity reflects both the number of species attacking pests (species
richness) and their relative abundances (species evenness). Recent experimental work …

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 …

Conservation biological control in agroecosystems requires a landscape management
perspective, because most arthropod species experience their habitat at spatial scales …

Throughout the last century, the multicolored Asian lady beetle, Harmonia axyridis (Pallas)
has been studied quite extensively, with topics ranging from genetics and evolution to …

How will biodiversity loss affect ecosystem functioning, ecosystem services, and human well-
being? In an age of accelerating biodiversity loss, this timely and critical volume summarizes …

Background Recent genomic analyses of arthropod defense mechanisms suggest
conservation of key elements underlying responses to pathogens, parasites and stresses. At …

Natural enemies are important ecological and evolutionary forces, and heritable variation in
resistance to enemies is a prerequisite for adaptive responses of populations. Such variation …

The suppression of agricultural pests has often been proposed as an important service of
natural enemy diversity, but few experiments have tested this assertion. In this study we …
