摘要：

The potential of the ground beetle, Megadromus antarcticus (Chaudoir) (Coleoptera: Carabidae) to prey upon slugs was investigated in laboratory and field experiments. This beetle preyed upon both Deroceras panormitanum (Lessona & Pollonera) and D. reticulatum (Muller) and consumed, on average, 0.55 slug per beetle per day. A positive linear relationship between slug density and slug consumption was observed. However, the biomass of slugs consumed remained relatively constant at 0.3 g slug per beetle per day. Slug numbers were reduced in small field plots of lettuce by beetle predation. However, this ground beetle is unlikely to be a useful biological control agent for slugs in intensive field crops because large innudative releases would be needed.
