SUMMARY Oulema melanopa and O. lichenis both transmit cocksfoot mottle and phleum mottle viruses with similar efficiencies. The viruses were serologically dissimilar and did not cross‐protect against each other in barley. Both viruses were acquired after a few minutes feeding, but longer acquisition feeding periods increased both the efficiency of transmission and persistence in the vectors. Acquisition of either virus increased vector mortality whilst acquisition of both together did not. When both viruses were ingested, only one was transmitted. Each virus could be recovered from haemolymph and faeces, but regurgitation was not observed and could only be induced with the greatest difficulty. The results suggest possible circulative transmission of some beetle‐borne viruses.
