Abstract
DAGGER nematodes (Xiphinema spp.) are now recognized as important crop pests in many North American states1–3 and occur widely in tropical countries4,5 in close association with plant roots. Because of their migratory ectoparasitic habit they are seldom observed feeding on the host plant, and where they appear to be associated with crop damage pathogenicity is difficult to prove.
