Abstract
Experiments conducted in sward boxes under controlled conditions showed that the carabid beetlesAbax parallelepipedus (Piller & Mitterpacher) andPterostichus madidus F. controlled slugs in a grass/clover sward. Control was shown to be as good as that by the molluscicide, methiocarb.A. parallelepipedus proved to be more successful thanP. madidus at controlling the slugs, damage to the clover being kept to a minimum.P. madidus controlled the slugs only after some damage to the clover was sustained.
Résumé
Des expériences menées en conditions contrôlées dans des boîtes carrées semées de trèfle ou de ray grass ont montré que les CarabesAbax parallelepipedus (Piller & Mitterpacher) etPterostichus madidus F. limitent les populations de limaces dans les champs de trèfle et de ray grass. La limitation par ces carabes se révèle aussi bonne que celle obtenue avec le molluscicide methiocarb.A. parallelepipedus semble plus efficace queP. madidus dans ce rôle, les dégâts sur le trèfle étant maintenus à un minimum.P. madidus ne limite les limaces qu'une fois le trèfle déjà attaqué.
