Effects of the spatio-temporal arrangement of agroecological cropping systems on generalist predators and biological regulation

2022

Facing the current agricultural challenges, agroecological systems place ecosystem services at the core of their production processes. Among these services is induced biological regulation, which keeps pest populations below an acceptable level in order to meet agronomic objectives. Despite the fact that this service is the result of an active scientific field, the effects of cropping systems that enhance regulation at supra-parcel scales are poorly understood. It is therefore essential to assess the effect of various cropping systems and agro-ecological infrastructures on natural enemy communities, as well as their resulting biological regulation potential, at broad spatio-temporal scales.…
