In South Dakota, wheat stem sawflies, Cephus cinctus (Norton) (Hymenoptera: Cephidae), are considered a minor pest. Previous surveys of wheat in South Dakota revealed limited detection of the wheat stem sawfly. One potential explanation for this is reduced wheat acreage compared to historical records. Rand et al. (2014) determined that wheat stem sawfly population outbreaks are dependent on the availability of wheat fields. An additional explanation may be the presence of parasitoid wasp species in South Dakota.
