Montana dryland spring wheat is frequently infested by both a grassy weed, wild oat, and the wheat stem sawfly, Cephus cinctus Norton. Although sawfly accepts wild oat for oviposition, mortality in this host species reaches 100% by the third larval instar. Factors such as host species abundance, relative host species abundance, and oviposition site proximity to adult emergence site were examined for potential influence on site-specific host species acceptance.

Species 1: Hymenoptera Cephidae Cephus cinctus
Keywords: host species acceptance
