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

Many plant‐feeding insect species considered to be polyphagous are in fact composed of
genetically differentiated sympatric populations that use different hosts and between which …

Host specialization in aphid parasitoids is important both from a theoretical and an applied
point of view. It arises from various ecological mechanisms involving their interactions with …

Few insects can match the ecological flexibility of aphids with their range of environmentally
and genetically determined phenotypes (Williams and Dixon, Chapter 3 this volume). They …

The ecosystem service of insect pest regulation by natural enemies, such as primary
parasitoids, may be enhanced by the presence of uncultivated, semi‐natural habitats within …

In agrosystems, the increase in non-crop plant diversity by habitat management in or around
arable fields contributes to improved Conservation Biological Control. During winter, plant …

Asexuality confers demographic advantages to invasive taxa, but generally limits adaptive
potential for colonizing of new habitats. Therefore, pre‐existing adaptations and habitat …

Given the negative environmental effects of conventional agricultural techniques, the need
for biodiversity-friendly agriculture systems that rely more on ecosystem services and less on …

A wide-ranging, interdisciplinary exploration of key topics that interrelate pest management,
public health and the environment This book takes a unique, multidimensional approach to …

Naturally occurring predators and parasitoids are known to reduce the abundance of pest
invertebrates in arable crops, yet current treatment thresholds do not account for such a …
