Abstract
The raspberry beetle (Byturus tomentosus F.) is a widespread pest of raspberry in Europe. Although it is being controlled chemically, alternative strategies should be developed, based on biological control by polyphagous predators. Laboratory feeding tests were used to investigate the role of raspberry beetle larvae in the diet of the carabid species, Pterostichus melanarius, P. niger, Carabus nemoralis and Harpalus rufipes. In no-choice and choice feeding tests with aphids or raspberry beetle larvae P. melanarius and P. niger preferred to consume raspberry beetle larvae. C. nemoralis quickly consumed both prey items. H. rufipes preferred to eat raspberry beetle larvae to Thlapsi arvense seeds. According to the consumed biomass of each food item, larvae of the raspberry beetle were preferred by each carabid species tested. Data reported here clearly indicate that large carabids − P. melanarius, P. niger, C. nemoralis and H. rufipes could play an important role in regulating raspberry pest populations.
