Évaluation et prévision du risque lié aux populations de limaces nuisibles aux grandes cultures : constitution d’un réseau expérimental permettant de comprendre l’impact des pratiques agricoles et des facteurs environnementaux (RESOLIM)

Abstract : In field crops, by the destruction of seeds and young seedlings, slug attacks are recognized as very harmful. This damage is often amplified in climatic conditions favorable to slugs and in the implementation of cultivation practices reducing the intensity of tillage. A large network of observations of more than 80 farmer plots and crop plant trials provided many data that were compared with information from other studies and literature. Slugs sampled from this network were studied in the laboratory in order to specify their thermotolerance and their biochemical composition during their growth. Data analysis provided details concerning the harmfulness of slugs, their life traits in fields cultivated during the seasons; the effects of different agricultural practices, beneficial organisms and weather conditions. This project contributed to the construction of a multicriteria assessment tool for slug risk and a conceptual model of slug population dynamics taking into account climatic factors. Nevertheless, their computer development remains to be made to make them available.
