Transmission of squash mosaic comovirus by Diabrotica barberi

During studies carried out in South Dakota on Cucurbita pepo plants affected by squash mosaic comovirus, the presence of Diabrotica barberi (EPPO A1 quarantine pest) and D. undecimpunctata howardii was noted. In transmission tests, it was found that D. barberi could act as an efficient vector for the transmission of squash mosaic comovirus in the field, as transmission percentages could reach up to 16.7 %.
