Summary When pollen of sowbane mosaic sobemovirus (SoMV)‐infected Chenopodium amaranticolor was dusted onto C. amaranticolor and C. quinoa test seedlings which were then infested with 5–10 adult Thrips tabaci , SoMV was transmitted to 25% C. amaranticolor and 88% of C. quinoa plants. Five hours access of T. tabaci to pollen‐contaminated C. quinoa seedlings was sufficient for SoMV transmission, but 1 h was not. SoMV was also transmitted when T. tabaci was mixed with pollen of C. amaranticolor and then placed on C. quinoa test seedlings. Further, plant‐to‐plant transmission of SoMV occurred in the absence of virus‐carrying pollen when T. tabaci was caged on infected non‐flowering C. amaranticolor or C. quinoa for 1–8 days and then adults transferred to C. quinoa test seedlings. This is the first time that thrips have been shown to be a vector of SoMV, and that a virus outside the ilarvirus group is reported to be transmitted using pollen and thrips.
