Resistance to the wheat curl mite (WCM), Eriophyes tulipae, derived from cultivar Salmon wheat, reduced the incidence of wheat streak mosaic by 58% in naturally infested wheat nurseries in 1979, 1981, and 1982. The transmission of wheat streak mosaic virus (WSMV) to WCM-resistant KS80H4200 was reduced by 74% compared to WCM-susceptible cultivar Sage in greenhouse seedling tests. Reduced transmission of WSMV to WCM-resistant cultivars coupled with WCM control in WCM-resistant volunteer wheat should give effective levels of WSM control.
