Filbertworm, Cydia latiferreana is considered as an economically important insect pest of hazelnuts, Corylus avellana in North America. Three entomopathogenic nematode species including Heterorhabditis marelatus Pt. Reyes strain, Steinernema carpocapsae All strain and Steinernema kraussei L137 strain have been tested as biological control agents against filbertworm under both laboratory and field condition (Chambers et al., 2010; Bruck and Walton, 2007). These studies showed that these nematodes can cause about 73–100% mortality of filbertworms (Bruck and Walton, 2007) and can be used to manage overwintering worms on the hazelnut orchard floor (Chambers et al., 2010).
