Transmission Of Triticum Mosaic Virus And Its Impact On The Biology Of The Wheat Curl Mite Aceria Tosichella Keifer (Eriophyidae), And An Evaluation Of Management Tactics For The Wheat Curl Mite And The Wheat-Mite-Virus Complex, Anthony J. Mcmechan
Department of Entomology: Dissertations, Theses, and Student Research
The wheat-mite-virus complex is an important production constraint to winter wheat production in the Great Plains, and consists of three viruses; wheat streak mosaic (WSMV), wheat mosaic (WMoV) and Triticum mosaic virus (TriMV). Synergistic interactions between these viruses have resulted in increased rates of replication and transmission of viruses, thus increasing the potential impact on wheat yields. The wheat curl mite (WCM), Aceria tosichella Keifer is the only known vector of the viruses within the wheat-mite-virus complex.
Currently, three colonies of WCM have been characterized by differential responses to mite resistant genes (biotypes) in wheat and differential transmission of WMoV. …
