Interpretive Summary: The wheat stem sawfly, Cephus cinctus Norton, is the primary arthropod pest of wheat, Triticum aestivum, in the Northern Great Plains. Rotation to non-host crops should decrease infestation of susceptible spring or winter wheats. Information is unavailable on wheat stem sawfly infestation potential of currently grown durum cultivars. Field trials were conducted in 1998 and 1999 to determine wheat stem sawfly susceptibility of thirteen spring durum cultivars and one hard red spring wheat. Pre-harvest infestations ranged from 2 to 55 percent. Post-harvest larval infestations of stubble ranged from 1 to 9.5 percent. Three durum cultivars, ‘Lloyd’, ‘Plenty’, and ‘Sceptre’ appear to offer potential, as a rotation crop, for management of wheat stem sawfly.
