The present study aims at measuring the influence of the diversity and spatial organization of organic and conventional farming practices on aphids and their natural enemies (ladybirds, predatory carabid beetles and parasitoids) in winter wheat. Higher abundances of beneficial insects were expected in organic fields and “organic landscapes” but with important variations due to practices diversity. Moreover, fields directly surrounded by extensive practices, either organic or conventional, were expected to present high abundance of natural enemies.
