Description:

Slugs are important pests of many agricultural crops, especially oilseed rape. The carabid beetles Pterostichus melanarius Illiger and Poecilus cupreus L. are among the most abundant large carabid beetles of European arable land and were therefore explored as potential slug antagonists. Damage to oilseed rape caused by the slugs Deroceras reticulatum Müller and D. laeve Müller in the presence or absence of P. melanarius and P. cupreus was observed in the laboratory. Whereas P. cupreus failed to reduce damage to oilseed rape by D. reticulatum, P. melanarius significantly reduced slug damage. However, P. melanarius was unable to protect oilseed rape from damage by D. laeve. This can be explained by the fact that D. laeve caused damage to oilseed rape below ground, where P. melanarius did not encounter the slugs. According to our laboratory experiments P. melanarius has the potential to reduce slug damage to oilseed rape by D. reticulatum.
