Hedgerows and beneficial phytophagous arthropods Organic Eprints
SIMON, S.; DEFRANCE, H.; RIEUX, R.; SAUPHANOR, B..
Introduction Organic Farming and Integrated Pest Management aim to favour and to rely on natural enemies for pest management. The ability of plant diversity to provide the orchard with natural enemies without any induced damage was studied: (1) in hedgerow lined orchards from different areas in order to assess the effect of hedgerows on the orchard arthropod community and (2) in experimental orchards, in order to test tree assemblages designed for the pear orchard, likely to supply the crop with psyllid (Cacopsylla pyri) antagonists. Materials and methods Arthropods were sampled fortnightly from April to October 1997 in eight (8) commercial pear orchards (Bartlett cultivar) and from main tree species of their lining hedgerows. For each tree species, 30...

Pest management and biodiversity in organic fruit production: the case of apple orchards Organic Eprints
SAUPHANOR, B.; SIMON, S.; BOISNEAU, C.; CAPOWIEZ, Y.; RIEUX, R.; BOUVIER, J.C.; DEFRANCE, H.; PICARD, C.; TOUBON, J.-F..
Numerous pesticide applications are required for orchard protection, regardless of the guidelines. Organic fruit production (OFP) mainly relies on the use of mineral fungicides and microbiological or naturally-occurring insecticides. The environmental impact of this type of production does not significantly differ from that of conventional production when assessed in terms of synthetic indicators. However, the abundance of earthworms, as well as the abundance and specific richness of arthropod pests and beneficials in the orchards and surrounding hedges, is greater in OFP than in conventional orchards. Generalist predators are usually less affected by OFP compounds than by the chemical pesticides applied in conventional orchards. OFP also benefits avian...
