The impact of entomopathogenic nematodes on a non-target, service-providing longhorn beetle is limited by targeted application when controlling forestry pest Hylobius abietis

► Entomopathogenic nematodes (EPN) are used to control the large pine weevil. ► EPN can infect and reproduce in non-target beetle Rhagium bifasciatum within deadwood. ► R. bifasciatum infection in EPN-treated deadwood was lower in field than in lab. ► EPN can locally persist in deadwood in the field by recycling in R. bifasciatum. ► Overall impact on R. bifasciatum is limited by targeted EPN application.
