    Abstract

    Field margins can attract and conserve predators and parasitoids, and thus contribute to pest suppression. On 20 hectares of organic farming, a network of field margins has been laid down to investigate two main questions: how far can field margins be apart and what vegetation diversity is required in order to achieve pest populations suppression? Pitfall traps and yellow water pans in field margins and crops are used to assess antagonists’ densities. Samples of key pests and damage assessments in different crops are related to the distance from the nearest margins. The first results out of these massive data sets are presented.
