Context Manipulating crop diversity in the landscape has been suggested as a promising management option to enhance biocontrol but how crop diversity independently of other important aspects of landscape structure affects predator and pest abundances remain largely unexplored.Objectives Our study assessed the relative and interactive effects of...

The farming practices adopted since the end of the Second World War, based on large areas of monocultures and chemical use, have adversely affected the health of farmers and consumers and dramatically reduced farmland biodiversity. As a consequence, many studies over more than twenty years have stated that agriculture is facing three main...

A considerable body of evidence has demonstrated the positive impact of the diversity of plant species on biological control of pests at the field scale. However, very few studies have assessed the effect of crop diversity on natural enemy performance and pest control. In order to test our hypothesis that crop diversity could increase natural...

Protéger les cultures par des moyens naturels est une nécessité pour la transition vers une agriculture respectueuse de l'environnement. Un effort de recherche et développement sans précédent est aujourd'hui mis en œuvre dans le domaine du biocontrôle, qui rassemble des approches basées sur l'usage d'organismes vivants et de produits d'origine...

International audience

The importance of plant richness to enhance the presence, biodiversity and efficiency of natural enemies in agricultural systems has largely been studied and demonstrated these last decades. Planting and preserving non-crop plants or manipulating crop richness in fields are practices that have proven their efficiency. However, the impact of...
