Popis:	Intercropping has potential as an alternative to chemical methods of pest control, and one of its effects may be to provide a favourable environment for beneficial invertebrates, including polyphagous predators such as carabid beetles (Coleoptera: Carabidae). This paper compares pitfall catches of carabids from clover-undersown cabbages and cabbages which were kept weed free by hoeing. There were four undersowing treatments consisting of two clover seed rates combined with high and low sward heights. Two species of carabid, Pterostichus melanarius and Loricera pilicornis, were collected in higher numbers from the undersown plots, but four species, Bembidion tetracolum, Trechus quadristriatus, Notiophilus biguttatus and Amara apricara, were more frequent in the hoed plots. All six of these species did not differ in numbers among undersown treatments. Two other species, Agonum muelleri and Bembidion lampros, did differ numerically among undersowing treatments, but the biggest differences were early...
